In theory, we could say that almost every projector can be a candidate when we’re looking for the best ceiling mounted projectors.
In practice, ultra short throw projectors are not intended for a ceiling mount. The whole purpose of a ultra short throw model is that it can be placed close to the projection screen so their convenience is in the fact that we don’t need to do a ceiling mount to enjoy whatever content we want.
In fact, if you have a ultra short throw and you don’t want to place it close to the screen the alternative is to do a wall mount.
Check out my reviews for the best projector ceiling mounts if you want to see what you need to know about ceiling mounts and which one would work best for your device.
On the other hand, short throw projectors can definitely be mounted on the ceiling without any problems. There’s a clear difference between short throw and ultra short throw models. But there might also be a few short throw models that don’t have any mounting holes on the back.
Thus, in order to do a ceiling mount, a projector must have mounting holes on the back. The distance between the mounting holes on your device must fit the arms of the mount, that’s how you determine compatibility between projector and ceiling mount.
Plus, portable and mini projectors are also not intended for being ceiling mounted. I guess the word portable clearly indicates that they’re made for being carried around wherever we want to use them, like using a projector for camping. They can also be a good pick for the best projectors for dorm rooms or for places where we can’t drill holes in the ceiling.
Best Ceiling Mounted Projectors
The fact that a larger majority of projector can be picked for the best ceiling mounted projectors doesn’t make things very easy or uncomplicated.
There are a lot of devices to go through in order to pick the best.
As I’ve already mentioned, portable, mini, and ultra short throw projectors won’t be included among my picks for ceiling mounted projectors.
To make things easier, I recommend having a budget in mind. This is a clear criteria to pinpoint which device would be perfect for you.
There are projectors for all price ranges: for budgets around $500 or under, between $500-$1,000, above $,1000, a few that cost between $2,000-$3,000, etc. In terms of price, my recommendations for the best ceiling mounted projectors will stop at about $4,000-$5,000.
I truly believe that everyone can find the most amazing device for them, no matter their budget and that’s what I intend to do. Don’t forget about pairing your device with an awesome projector screen if you want to make the experience truly magical.
Also, if you change your mind and you decide that drilling holes is not exactly what we want or can do, then there’s an alternative that will work for projectors that are not very big or heavy. You can buy a projector tripod stand.
There are some that will have a max load of 11 pounds but there are also stands that have a max load of 33 pounds. If you decide to go this route, the weight and size of your device is extremely important.
1. Epson Home Cinema 5050UB: Overall the Best Ceiling Mounted Projector
However, it’s also one of the most expensive models we could buy, with a price around $3,000. Not many people are going to be able to afford this one but if you’re looking for an amazing model, this Epson Home Cinema 5050UB certainly fits the bill.
It also is one of the best projectors with horizontal lens shift.
Given just how expensive this Epson is, some people might expect it to be a laser 4K. After all, there are plenty of laser projectors that are so much cheaper.
Unfortunately, it’s still a lamp-based model.
That might be a deal breaker for some. If you don’t enjoy thinking that you’ll have to change the lamp at some point in time, certainly after a few good years of use, then you might not be too excited about the Home Cinema 5050UB.
I don’t have a problem with it since I’m completely used to this type the most.
The lamp life is up to 3,500 hours on High Mode, up to 4,000 hours on Medium Mode, and up to 5,000 hours on ECO Mode.
It uses advanced 3LCD technology, which is the norm for all Epson models. LCD is awesome for those who have experienced the rainbow effect with DLPs. LED DLPs are the only ones where there’s no risk of rainbow effect.
Epson Home Cinema 5050UB is a 4K PRO-UHD 3-Chip HDR projector.
Epson calls it the ultimate 4K experience for the DIY home theater. It certainly can be for those who can afford what it offers.
Since we’re talking about resolution, let’s understand what 4K PRO-UHD means.
It’s certainly not true 4K.
4K PRO-UHD is called 4K Enhancement by this brand. It’s described as being 1920 x 1080 x 2 pixels.
The image is created with the help of an advanced pixel-shifting processor and that’s why it’s named resolution enhancement technology.
What we can say is that the 4K visual experience is fantastic. But the same applies for Full HD content. We must also keep in mind that most content is still Full HD.
Epson Home Cinema 5050UB stands out and creates the best visual experience no matter which content we enjoy, in whatever resolution it comes. That is its true power and what makes it my first choice for those who can afford it.
The maximum supported resolution is 4096 x 2160. And that’s true 4K. So it plays true 4K content but the native resolution is 4K PRO-UHD (3840 x 2160).
Is there a difference between 4K UHD and true 4K?
In numerical terms, the difference is 500 million pixels.
In terms of cost, obviously 4K UHD is the cheaper alternative to native 4K projectors, like the ones from Sony or JVC.
However, when it comes to the viewing experience, most of us will notice no difference. Both are excellent and both resolutions offer jaw-dropping experiences to even the most hard to please viewers.
We get a brightness of 2,600 lumens.
Can we use the Epson 5050UB during the day?
I would say that the answer is no. 2,600 lumens is not enough for decent daylight viewing.
I found a YouTube video on the Epson 5030UB on how it performs in daylight. It should give you an idea about how the 5050UB would do in similar conditions.
Obviously, home theater projectors are best enjoyed in the dark, in a home theater setting as their name suggests. That’s when they truly shine.
Data projectors (for education and business purposes) are the ones that have a really high brightness so they can be used during daylight.
The contrast ratio is up to 1,000,000:1.
The throw ratio is 1.35-2.84.
We also get vertical and horizontal lens shift.
And there’s vertical and horizontal keystone correction +/- 30 degrees.
Yes, this is a 3D projector but you’ll have to buy compatible 3D glasses if you want to enjoy this type of content.
In 3D we get two color modes: Dynamic and Cinema.
For 2D we get the following color modes: Dynamic, Bright Cinema, Natural, Cinema, Digital Cinema, Black & White Cinema.
We get the basic but nothing impressive: 2 HDMI, USB-A, USB for wireless and firmware, Mini USB but it’s service only, LAN.
It’s not a wireless projector.
One thing that might bother some people is that this Epson doesn’t have built-in speakers.
I’m certainly not bothered by the lack of an internal speaker because I don’t use it anyway.
However, I am bothered by the fact that we don’t get an Audio out port. I really don’t get it because having an Audio out connection is so helpful to many people.
Anyway, there are certainly alternatives from connecting the audio system to the video source, or connecting your speaker to the streaming device that is connected to the projector via HDMI or you can use an AV receiver, etc.
The thing is that I really don’t see why there’s no Audio out included when the Epson 5050UB is such an expensive model.
There’s also no Bluetooth support. Bluetooth speakers are very popular for those who don’t want to spend money on a bulky audio system.
You can still use them even with this Epson by connecting the Bluetooth speaker to your streaming device (Roku, Chromecast, etc.) or to your source device (tablet, smartphone, laptop, PC).
It measures 20.5 x 17.7 x 7.6 inches.
And it weighs 24.7 pounds.
Where to Buy?
2. Epson Home Cinema LS11000: Impressive Ceiling Mounted Projector
It’s one of the newest projectors from Epson. And this time we have laser technology for those who can afford to pay for it.
Obviously, the LS11000 is going to be my most expensive recommendation for the best ceiling mounted projectors.
What we can safely say is that the Epson Home Cinema LS11000 comes as close to perfect as it possibly gets, which is the highest distinction we could offer it.
Being a laser projector means that there’s no lamp to change, there’s basically no maintenance, and the brightness decreases less noticeably as years pass.
We get an estimated life span of up to 20,000 hours for normal, medium, and eco mode. There’s no difference for laser models.
We could say that the Home Cinema LS11000 is the laser alternative to the above Home Cinema 5050UB.
It’s the answer for those who love what the 5050UB has to offer but are not comfortable with lamp projectors.
And it’s the perfect option for those who can easily afford spending about $4,000 for one of the most desirable projectors at the moment.
It’s a beauty in all aspects.
Still, I want to answer a question since we have two outstanding Epson models that are two of the best ceiling mounted projectors.
Is it worth buying the LS11000 over the 5050UB when you have to pay an extra $1,000?
In my opinion, no.
I would choose the 5050UB over the LS11000 and invest that $1,000 price difference in anything else that I want, like maybe some speakers, if you don’t already own some.
Even the laser technology isn’t enough to convince me that the Epson Home Cinema LS11000 is the one I would choose.
I prefer the idea of changing the lamp in many years down the line because I simply believe that the Epson Home Cinema 5050UB offers the better picture, it’s capable of overall better image quality between the two.
Basically, if you see that a projector costs less than $5,000, you can expect it to be a 4k UHD and not a native 4K. There might be a few exceptions to this rule but I don’t know about them.
That’s the case for the LS11000, too.
We get 4K PRO-UHD resolution, 3840 x 2160 pixels. It’s quite close to true 4K so I don’t consider it a con, not in the least.
Of course, it projects the image with the help of 3LCD chip technology. For those who are sensitive to the rainbow effect that some DLPs create, LCD is the alternative.
There’s also an up to and over 1,200,000:1 contrast ratio.
Of course, there’s vertical and horizontal keystone correction +/- 30 degrees. And we get horizontal and vertical lens shift.
The throw ratio range is 1.35 – 2.84.
We get a brightness of 2,500 lumens. This is absolutely a projector that must be watched in the dark.
If you want a projector that looks pretty decent in ambient light, I wouldn’t recommend considering the Epson LS11000.
However, in dark settings, you’ll be blown away by the overall picture quality.
I would also say that this Epson can be quite a fantastic model for those who want to project a really big image, like on a 150 inch projection screen.
It seems that for these two expensive 4K UHD models, Epson doesn’t offer that many connections.
We once again get just the basics: 2 HDMI, 2 USB-A, service only mini USB, and LAN.
Once again, we get no Audio out and no Bluetooth.
I’ve already mentioned alternatives for connecting audio systems if we have no Audio out or Bluetooth when I reviewed the Epson 5050UB just above.
Of course, there are plenty of alternatives we can use for audio systems of all types and they’re very easy to put in practice. That still doesn’t mean that I approve that Epson didn’t include an Audio port.
I should also mention that the Epson LS11000 is not a 3D projector. The Epson 5050UB is. I don’t mind either way but it might be something that matters for some people who are looking for the best ceiling mounted projectors.
It also doesn’t support Dolby Vision but I’m not going to count it as a con because there are only a few projectors with Dolby Vision. These are certainly not the norm and I don’t think that it’s a huge loss not having DV.
It measures 10.5 x 17.6 x 7.6 inches.
And it weighs 28 pounds.
Where to Buy?
3. Epson Home Cinema 880: One of My Favorites
If you’re willing to buy one of the best ceiling mounted projectors for a price under $1,000, then the Epson Home Cinema 880 might be right up your alley.
Also, I might give the impression that I’m writing a post dedicated to Epson but they really do have amazing models that fit so many budgets and requirements. If you don’t like Epson, you’ll find other options recommended below.
In a price range of $700, you can totally expect a lamp projector. LED projectors are also cheap but laser models are expensive.
However, what I love is that this Epson 880 has a high lamp life, much better than a lot of other lamp projectors.
We get up to 6,000 hours on normal mode. It’s truly great.
There’s also Eco mode for which we get up to 12,000 hours.
However, I’m sure that most of us are going to prefer using the normal model because the Eco mode decreases the brightness of the lamp.
Still, 6,000 hours on normal use amounts to a lot of years of running this projector without needing to get a replacement lamp.
Projectors with Full HD native resolution are still amazing, even as we become surrounded more and more by 4K models.
An 1080p device is still amazing to use, whatever content we enjoy watching. I love it and, for this price level, we couldn’t ask for better image quality.
What I love about the Epson Home Cinema 880 is that it gives the impression that it’s more expensive than its real price.
It doesn’t support 4K content so we’ll enjoy only 1080p content. We can of course play 4K content but it will be plated at 1080p.
There are Full HD projectors that have a 4K max supported resolution but that’s not the case for this Epson 880. Frankly, we’re really not losing anything.
There’s also a 16,000:1 contrast ratio. It’s obviously not a high number. It’s a decent contrast, in my opinion.
If we watch in dark rooms, it will be more than enough.
Frankly, its ability to play life-like images is what makes this Epson 880 one of the best ceiling mounted projectors for people on a budget. There’s a high chance that you’ll love it.
We get 4 modes: Dynamic, Bright Cinema, Cinema, Natural.
+/- 30 degrees both vertical and horizontal keystone correction, which is typical for cheaper devices.
The throw ratio range is 1.21-1.63. It will work well even for smaller rooms and that’s why I also reviewed it as one of the best projectors for the bedroom.
What is incredibly impressive about this Epson Home Cinema 880 is the high brightness.
This one has a volume of 3,300 ANSI lumens.
There’s a high chance that you’ll be able to love it in ambient light as well. For example, if you’re looking for a projector for watching sports that costs less than $1,000, this one might be it.
I’m really satisfied with the connections we get: HDMI, LAN, USB Plug ‘n Play, USB Type A, Audio out.
I’m glad that we have an Audio out port for speakers and audio systems of all kinds.
It also supports Mira casting for smartphones, laptops, tablets. If you want to know how to project from a phone, you’ve just found out that Epson 880 offers a very easy answer.
There’s also a very tiny 2W built-in speaker.
There’s no Bluetooth support.
And it’s not a 3D projector.
It measures 11.9 x 9.3 x 3.2 inches.
And it weighs just 5.95 pounds.
It’s a small and quite lightweight device. If you want to use a tripod stand instead of doing a ceiling mount, that will work, too.
Where to Buy?
4. BenQ HT2150ST: Best Gaming Ceiling Mounted Projector
This is another favorite of mine as one of the best ceiling mounted projectors.
In case you’re interested, BenQ has a universal ceiling mount but you can also buy another one from a different manufacturer as long as you make sure that the distance between the holes fits the arms of the mount.
Of course, given the affordable price, we can only expect it to be a lamp-based projector. Well, LEDs are also cheap but LED projectors are usually portable so they don’t qualify as ceiling mounted projectors.
The lamp life span is nothing impressive but there are other much more expensive models who sport the same numbers.
We get: 3,500 hrs for Normal, 5,000 hrs for Eco and 7,000 hrs for SmartEco.
It’s decent but certainly not the best lifespan.
This is also a DLP projector. BenQ, Optoma and a few other brands are well-known for their DLP models.
It’s an amazing technology and the image quality can be even better than what we get with some LCD models if it’s done right.
The problem is not in the image quality because I have no complaints.
The thing is that some people might be affected by the rainbow effect. It might not be bad and you won’t know if you’re one of those until you actually try using a DLP.
I’m not affected at all but my boyfriend can spot it from time to time, although he says that it’s not annoying. So, not everyone is susceptible to the rainbow effect and that’s why we can’t know for sure who will be unfortunate or not.
Of course, we get Full HD native resolution.
There are also a few picture modes to choose from if we don’t want to make our own calibrations: 3D, Cinema, Game, Game Bright, ISF Day, ISF Night, User, Vivid.
The 15,000:1 contrast ratio is not all that exciting but what can we do, nothing is truly perfect. It’s just decent.
We should also mention that this is actually a short throw projector.
It has a 0.69-0.83 throw ratio.
It’s great if you want to install it in a smaller room. Or if you want to create a very big image from a shorter distance.
Still, when it comes to Full HD projectors, I recommend sticking to projecting on 100 inch screens, maybe 120 inch if you want something bigger.
There’s only vertical keystone correction, no horizontal.
The brightness is nothing impressive so you’ll have to use this one only in dark environments.
We get 2,200 ANSI lumens, which will be beautiful in the dark but won’t be enough for ambient light.
One of the features you’ll notice about the BenQ HT2150ST is that it’s advertised as a gaming projector.
BenQ boats of ultra-fast 16ms low input lag.
It is supposed to convey our sights, hearings, and thoughts into actions with zero delay.
16ms is a good latency. I would say that a 0ms to 16ms input lag is unnoticeable, which makes this HT2150S claim that it will work perfectly as a gaming projector. I’m impressed.
Besides being a gaming projector, it’s also a 3D projector.
Of course, you’ll have to buy compatible 3D glasses, which cost about $50 or a bit more per pair. The ones you need are called DGD5.
We get the usual and the classics: 2 HDMI ports, PC, DC, USB, mini USV, RS232, Audio out/in.
One of the HDMIs is for 3D content.
There are also 2 built-in speakers 10W.
It measures 15 x 4.8 x 10.9 inches.
And it weighs 7.9 pounds. It’s not the lightest but it’s still lightweight.
Where to Buy?
5. Optoma HD146X: Affordable Ceiling Mounted Projector
For that low price, I absolutely love the Optoma HD146X as one of the best ceiling mounted projectors.
I own both an Optoma and an Epson. Since my Optoma is quite small and really lightweight, similar to this HD146X, I have it on a stand, placed right behind my couch so it’s not in anyone’s way. But you can totally do a ceiling mount if that’s what you want.
Still, when it comes to such tiny and lightweight devices like this Optoma HD146X I find it much easier to use a tripod stand. But that’s also because I can’t do a ceiling mount for all my models.
And I like having a projector that is portable and can be used in various rooms of the house. I have a wall mounted fixed frame projector screen exactly for that purpose.
I really love Optoma. While I am aware that their various models receive quite a few negative reviews, I really love mine.
Optoma manages to do exactly what I’m looking for: sharp images, bright colors, amazing contrast, lightweight devices, and just an amazing overall image quality for affordable prices.
Of course, Optoma also has 4K projectors that are quite expensive, some costing $5,000 or more. But I think that Epson is better at the whole 4K thing, it’s a better choice, although Epson’s prices might make some of us want to cry.
Anyway, the Optoma HD146X can be an awesome model for people with a budget around $600. I think it’s one of the best if you don’t want to spend more than that.
Naturally, the Optoma HD146X is a lamp model. But we get some good numbers.
The lifespan is: 4,000 hours for Bright, 15,000 hours for Dynamic, and 10,000 hours for Eco.
It’s another DLP projector, Optoma is famous for them. Still, you must keep in mind that there’s a chance that you might be affected by the rainbow effect.
We get Full HD native resolution, which is great, especially considering the affordable price.
There’s also a pretty high 25,000:1 contrast ratio. As far as my experience has been, Optoma has awesome contrast.
We only get keystone vertical correction so you must be careful with positioning it carefully when you do a ceiling mount before drilling the holes.
The throw ratio is 1.47-1.62.
This is where things are really impressive.
It has a 3,600 lumens brightness.
That means that it’s fabulous in the dark but it also works quite nicely in ambient light, especially if it’s paired with a good ALR (Ambient Light Rejecting) projecting screen.
If you want to watch content in ambient light, you absolutely need an ALR screen.
The Optoma HD146X is among one of the most affordable 3D projectors.
It has a 16ms input lag, which is low enough for gaming. It’s a projector full of surprises, that’s for sure.
We get a few ports, very basic but exactly what we need: HDMI, Audio, and USB-A.
There’s no Bluetooth support.
There’s also a 5W speaker.
Separately, we can buy the Wireless HDMI System WHD200. This accessory is only needed to provide wireless streaming.
On the other hand, instead of buying this wireless system, you might prefer spending your money on a streaming device. It depends just what devices you prefer to use.
It measures 4.3 x 12.4 x 9.5 inches.
And it weighs just 6.2 pounds, it’s very light.
Where to Buy?
6. Epson EpiqVision Flex CO-W01: Cheapest Ceiling Mounted Projector
If you find this EpiqVision Flex CO-W01 being sold for a price around $300, then it’s totally worth the price. I don’t think there could be a better deal than that.
I will admit that the EpiqVision Flex CO-W01 is not the most impressive at first glance but for a price around $300, I don’t think it gets any better than that, really.
Of course, we get a lamp projector but we get a really amazing life span.
On normal mode we get up to 6,000 hours.
Eco mode can make the lamp last up to 12,000 hours until the brightness decreases significantly and we need to buy a replacement lamp.
It’s also a LCD model so there’s no worry about the rainbow effect.
It’s mainly created as a business projector but it also works well for movies or TV shows or other entertainment content. It’s good for both.
The WXGA (1280 x 800 pixels) resolution is really good. It’s not as good as Full HD but if you buy the EpiqVision Flex CO-W01 for $300-$400 it’s totally worth it.
There’s also +/- 30 degrees vertical and horizontal keystone correction. No lens shift because this is a cheap device so we won’t find lens shift among their specs. Just keystone correction.
Epson describes the EpiqVision Flex CO-W01 as being perfect for business and epic for play.
When we see words like business or education then you should expect a high brightness.
The 3,000 lumens indicate a very high brightness.
We will get good quality images in a variety of lightning conditions.
It will be good in ambient light but I recommend enjoying your favorite entertainment in the dark.
These are the very basic: HDMI and USB-A.
Once again, there’s no Audio out so you’ll have to connect your speaker or audio system to your source device (laptop, tablet, PC) or you’ll have to connect it to your streaming device (Roku, Fire TV, Chromecast, etc.).
We also get a built-in speaker.
It measures: 11.6 x 3.4 x 8.3 inches.
At 5.3 pounds, it’s a portable, lightweight projector that can be ceiling mounted if that’s what you want.
Where to Buy?
7. Epson Home Cinema 3200
While I reviewed models in a wide variety of price ranges, I still didn’t include a single device in the $1,000-$2,000 price range.
Once again I’m back to Epson because they have the perfect model if this is your price range when you’re looking for the best ceiling mounted projectors.
Frankly, I am totally aware that Epson featured a lot in my recommendations but they do have some of the best devices at the moment so it’s really not my fault. I also love that they have a model for everyone, no matter what our budgets, needs or expectations are. That’s why I ended up reviewing so many models from them.
While we saw what Epson offers for prices around $3,000-$4,000, we also saw what this brand offers for budgets under $1,000.
Also, if you are on an under $1,000 budget and you want something different, I also recommended two excellent options from BenQ and Optona. There’s plenty for everyone.
I should also admit upfront that Epson Home Cinema 3200 is an impressive projector and I’m sorry that it ended up being mentioned last but that’s how it ended up being.
Just because it ended up being last, it doesn’t reflect on its quality. Quality is top-notch.
You’ll get your money’s worth if your budget is under $2,000. It’s pretty much amazing, although we should expect a lot from it since it’s certainly not cheap.
In this price range, you can definitely come across laser projectors from quite a few brands.
However, when it comes to Epson, their laser models are going to cost a lot more than this Home Cinema 3200.
Thus, we get a lamp-based device with the following estimated lifespan: 3,500 hours on High mode, 4,000 hours on Medium mode, and up to 5,000 hours on Eco.
That’s not an impressive lamp lifespan but it will last a few good years.
This is where things get extremely exciting.
We actually have a 4K PRO-UHD native resolution.
As we’ve already said, 4K UHD is not true 4K but they’re close enough for most of us. Frankly, I don’t really care about the distinction between these two.
I’m just happy to say that the Epson Home Cinema 3200 is a 4K projector for a pretty good price.
The 40,000:1 contrast ratio is very nice, too.
It doesn’t get close to reproducing the same ultra-deep blacks that a high-end model does but it still has a really nice contrast.
The lens shift is pretty awesome. We don’t get the biggest numbers but it’s still more than enough.
+/- 60% vertical lens shift.
+/- 24% horizontal lens shift.
Besides the amazing high resolution, this Home Cinema 3200 also has a pretty impressive brightness, as well.
It boasts of a 2,900 lumens brightness. That means that it can be used in ambient light, which is very nice.
It utilizes tone mapping to maintain bright highlight details and full screen brightness.
I’m sure that there would be some people who would be glad to see that the Home Cinema 3200 is also a 3D projector.
We get the usual: 2 HDMI, USB-A, USB for wireless accessory, mini USB for service only, and Audio out.
It’s pretty amazing to see that this one does have an Audio out port.
It measures 16.1 x 13 x 6.5 inches.
And it weighs 14.6 pounds so it’s not all that heavy, it’s in the middle.
Where to Buy?
Overall, I hope you enjoyed my reviews for the best ceiling mounted projectors, it has been my pleasure to be able to review all these awesome models.
Best ceiling mounted projectors FAQs
Let’s answer a few questions related to our search for the best ceiling mounted projectors.
1. What projectors can be ceiling mounted?
A large majority of projectors can be ceiling mounted. Every projector that comes with mounting holes can be ceiling mounted. The only ones that are an exception are portable, tiny projectors.
2. Should I mount my projector on the wall or ceiling?
Most of us prefer doing a ceiling mount. But a wall mount is also a possibility, especially for ultra short throw projectors.
3. How do you run power to a ceiling mounted projector?
We usually choose to use a cable that is long enough to reach an electrical outlet from the projector that is mounted on our ceiling. We can tuck the wires behind crown molding. Or we can run the wires down a window frame. Another option for hiding projector wires is to hang soundproofing material to cover the wires. Of course, we can always sneak wires behind your couch and other furniture. The other option is to install an electrical outlet and wiring in the ceiling next to our projector. All in all, besides lookin for the best ceiling mounted projectors, there are these kinds of considerations to keep in mind, too.
