“Had the Optoma UHD50X for a while and eventually returned it because it started getting dead pixels all over and they wouldn't be able to fix it for over a year with warranty.”— spicyrocket1 on Reddit
“Had a UHD50x for a year, it got a good amount of use but roughly one month outside warranty I had over 5 dead black “pixels” and a few white ones, from the DLP chip sticking/dying. The lenses were also visibly yellowing (almost a tobacco color)”— TheGoingVertical on Reddit
“in almost 3 years I've changed the bulb twice and the DMD chip 3 times because of dead pixels on my UHD50x. Like others, it will be my last purchase from Optoma.”— Jedcrandy on Reddit
“I have 2 dead pixels on my 2 year old uhd50x…I’m very skeptical of this and already bought a non Optoma replacement”— crushinit2 on Reddit
“I dropped my uhd50x after a year for the LG OLED it's way better. Other than size of screen it's not even close.”— soldier70dicks on Reddit
“I found the Optoma to just be too bright. It could not achieve dark enough black levels when watching movies. The darkest areas were a dark grey.”— getbiggetlean on Reddit
“My UHD50X started displaying a white dot around 14 months of ownership. It was extremely embarrassing having people over with a defect like that showing up on the screen. I replaced the DMD chip, but now I have a couple other issues. I would recommend avoiding this brand as others have mentioned.”— RubiconTitan on Reddit
“Optoma was not as color accurate and black as 2050A,”— bohaan on Reddit
“With the uhd50x last month I encountered color degradation from normal to fade and shifting color tone’s until completely failure with lamp code led.”— Ramado1972 on Reddit
“The UHD50X isn’t as great as Optoma wants people to believe it is. It downscales 4K to 1080p in its “4K game mode”. They have lied with their marketing.”— pixelpusher15 on Reddit
“My issue with the optoma was extremely bad banding on light sky scenes or anything where the light source originates (ie candlelight) while using HDR. It was fine viewing in SDR. But the HDR image was trash.”— MrMojoRyzing on Reddit
“I have the UHD50X and have just disabled HDR because there were more issues (primarily terrible banding) and very little/no benefit to the picture since the projector can't do real HDR.”— RipGroundbreaking892 on Reddit
Not complaints — practical notes from owners that didn't affect the score.
“I have the UHD50X as well. I’ve not noticed any colour banding, but sometimes my screen will have a clear vertical division down the middle where one half the screen looks slightly different colour/brightness than the other. Simply hitting the “refresh display” button (right arrow) fixes it.”— ON3i11 on Reddit
“The Optoma will do 1080p@120Hz but the Epson won’t go beyond 60Hz in any resolutio. On the other hand the Epson will give you better blacks/colors and no rainbow effect”— reward72 on Reddit
“I had a single dot on my UHD50X. It drove me nuts. New DMD purchase through eBay, $247.92. It took a couple of hours to repair.”— Burgh15071 on Reddit
“Its definitely not as crisp as my monitor but I was never expecting it to be.”— Spanishsoul on Reddit
