Projector selection advice sub $2k

***updated

Alright im finally back on track with my basement HT build...
So heres the layout
100% light controlled dedicated room, fabric walls, black ceilngs
178" AT screen 16:9 .8 gain? Old theater screens or carls
Probably 60% gaming 40% movies & sports
2 rows of 3 seats 1 riser with a bar and stools behind the back row, front row at 11'
I understand thats close seating but we literally built our basement with 9.5' ceilings just to accommodate a 170-200" screen.

Looking at a few different projectors-

Epson 4010
2400 lumens
200,000:1


Epson 5040ub
2500 lumens
1,000,000:1

Benq ht3550
2000 lumens
3,000:1

Epson PowerLite Pro G7400U
5500 lumens

The lumen claim by manufacturer are not accurate. You can get them from reviews which have measured them. Same with contrast.

An 185" screen is very large. How have you come to this diagonal?

What kind of AT screen is it, how do you know it's 1.1 gain?

What is the seating distance?

Color of walls?

What is the source?

First our definition of a 100% light controlled dedicated room will have no white/light colored surfaces like a white ceiling. If that's the case the 5040 refurbed deal is the only projector in your list I would even consider. This is also if you can deal with the 10Gb HDMI that will defiantly cause issues with many streaming devices and gaming consoles. The Epson 3800 is more likely a better fit (18Gb HDMI/brightest in this class) especially if your surfaces aren't dark non reflective. Rarely do you see an AT screen even get to a gain of 1.0 so check from independent sources don't trust the manufactures spec. 185" is a big screen so forget HDR as it's sure to be too dim.

Yes i know it is a large screen its the biggest i can fit and still be able to fit trim up top and a platform on the bottom etc. Thats the reason we built our basement with 9.5' ceilings so i can fit a 200ish screen.
*Screen: i have 2 options a local big theater closed and i can get some of the screens they removed or ill likely go with the carls screen
*front row is 11' away from the screen
*walls will be dark and ceilings will be black
*video source will be oppo blue ray, xbox oneX, DirecTV reciever, computer

Before deciding on a screen size the projector should be used an a surface for a few weeks.

A very general ratio is 10-12" in diagonal for every foot in distance. There may be seat rows after the first, but 185" from 11' is very close.

As rekbones said above, the highest gain white AT screen is ~0.95. I don't know what gain the theater screen has, but I doubt it's 1.1. Very likely 0.8 or lower.

While there is some preference on how bright a screen should be, for an 185" AT screen there is no Home Cinema projector I could recommend. You would need some sort of small venue unit, which is a few times the budget.

For SDR the minimum recommendation is 12-15fL, but HDR needs a lot more. With lamps aging the initial brightness should be higher to compensate.

Even some of the brightest projectors in HC, the Epson HC3700 and HC3800 (for 4K) are probably not enough. They will have to be used in High lamp and placed closest to the screen to get the highest brightness.

The HC3700 is ~15% brighter than the HC3800.

Use this calculator:
https://webprojectorcalculator.com/

So I highly recommend the diagonal be lowered, like ~150".

The HC3000 series don't have great blacks/contrast. The 5040/5050UB is better, but it would be at the limit with an 150" screen on an AT screen of unknown gain. For SDR it would probably be fine, but not sure for HDR.

Getting a Panasonic UB420/820/9000 will help with HDR, but I would still not go over 150". No gaming, just movies/streaming.

The 5040UB has a 10GB HDMI which limits some streaming services for 4K HDR and 4K gaming.


The 150" recommendation is for watching with lights off. With some ambient light you need an actual light cannon.


LE: also for lights off viewing, with a smaller screen of course, DLP projectors have better motion handling so better for sports and gaming if it's fast paced. But black level will be lacking.
The Optoma UHD52ALV is somewhere between the 5050UB and HC3800 brightness wise.

The Optoma UHD50X will be best for gaming but see this thread for some user comments:

https://www.avsforum.com/forum/68-di...-canadian.html

IMHO, based upon using a UHD50 (and a Viewsonic PX-747-4K) on a 145in low gain, grey screen, I think you'll be fine at 185in 1.1 gain screen.

Not too familiar with venue projectors. Since the unit might exceed $3K might want to post here:
https://www.avsforum.com/forum/24-di...-000-usd-msrp/

Something like that, g7500u even. If the screen is going to be the same. Sure there is some room for preference, but from 11' first row and 14' second, an 185" is too large. As I mentioned if the screen is smaller you could go for the 3000 or even 5000 series.

Or LS800WU.

The Epsons probably have better black level and are brighter.
