New Projector Needed - Help Please

I have an Optoma UHD55X which has been a decent projector (apart from HDR) but it has now developed a single dead pixel right in the middle

So think I need a new one as dead pixels are not cheap to repair and have been looking at the Epson EH-TW7400

Can anyone comment on the comparison between this projector and my current one please ? In particular the 4k pixel shifting. The Optoma uses the Texas Inst chip but the Epson does not - does it do as good a job as the Optoma in this regard ?

Must admit the size of the projector is putting me off a little so if anyone can recommend an alternative I would be grateful.

I have a home cinema room with screen but it is not man cave level (e.g white ceiling and light-ish walls) so am taking that into consideration.

Many thanks for your help and support :)

Screen size?

Seating distance?

From what I've read the optoma has a slightly sharper image but the Epson has better contrast. Bottom line you really need to find a dealer and see if the change is to your liking. Personally I'd go for the Epson.

About 120" screen size. Seated about 12ft away
4K 3LCD on the Epson has ~4m pixels, with ~8m on 4K DLP.
Other factor that influence sharpness is lens quality. The TW7400 has better lens than a lot of projectors in this budget.
Another factor is the source. 4K is better than the source. But even if the video is 4K, many movies for example are shot in 2K and upscaled to 4K. There is a difference in sharpness. There are only ~80 titles shot in 4K.
Seating distance and visual acuity are also a factor.
Finally contrast can improve perceived sharpness.

Generally speaking, the TW7400 on an 120" screen from 12' is fine, may be less sharp in certain scenarios.

One issue with it is that it has a 10GB HDMI. Which means it can't do 4K HDR 60Hz, 30Hz at the most. 60Hz is required for gaming and some streaming services.
This bottleneck can be bypassed by dropping the bit depth from 10bit to 8. Outside a PC/Shield, an HDFury linker can do it.
I don't know if it's worth it.

Can the walls be treated for reflections? They have a negative effect on the contrast/black level of any projector:


If yes then get a TW9400. It's the good black version of the TW7400. It also has a 18GB HDMI.


If no get a Benq W2700 or Optoma UHD50/51/300x/350x or TW7400.
The W2700 and TW7400 have active irises which will help with black level. They also cover a larger part of the DCI P3 spectrum, even without the filter.


As for HDR tone mapping, it's still not a mature feature. For best results get a Panasonic UB420/820/9000 (last two have Dolby Vision).
If using a HTPC, madvr is great, but it can't do streaming.

Many Thanks Noob0101 that's great information there.

I will certainly look at those alternative projectors you suggest, the sheer physical size of the Epson is off putting - although it will be hung from the ceiling it is still will be very obtrusive.
