Optoma UHD35STx Short Throw True 4K UHD Gaming and Home Entertainment Projector 3,600 Lumens 240Hz Refresh Rate and Ultra-Low 4ms Response Time

Incredible. It is I think worth the price tag for 4K with silent noise. Had an old Viewsonic HD3D that was making so much noise on top of our heads, we had headaches watching stuff over time.... then we tried optoma laser DX2 but it's absolutely horrible (I have a separate review on it). Was about to abandon optoma brand entirely, but tried this one as last ditch effort. Wow. just wow. Makes almost no noise after hours of watching. Someone on youtube made a video review on this one and I couldn't hear the fan noise while he was talking, very close to the device. So I tried it. No regrets, it's awesome. wow.

It's a really good projector if you want a huge screen. I get a 190" picture that covers my whole wall from 7' distance, and this is priceless. It also provides a great contrasty HDR. Better than some other DLP projectors I tried, and very close to my 4K HDR DisplayHDR 600 certified 32" screen. It does need some tuning though. I have a yellowish drywall. It's not a dedicated screen, low gain, so my settings are: Brightness: 5, Contrast: 9, Sharpness: 9, Color: 50, HDR/HLG: Auto, HDR Picture Mode: Bright, HDR Strength: 9, Brightness Mode: Bright, BrilliantColor: 10 I also tuned colors a little to negate yellow tint of my 'screen': Color Temperature: D75, Wall Color: Off, Red: -6 13 18, Cyan: 10 0 20, Yellow: -19 3 15, Magenta: 21 0 20. Don't forget to switch on 10 bit on your source too (I have Fire Stick 4K). And if you're on Apple TV switch Chroma to 4:2:2 (makes a huge difference, but you also need an HDMI 2.1 cable) It took me quite some time to figure out those, maybe it helps others. What I like about the picture that it gives you a depth sense. I tried some other brands, picture looked too flat. And even before tuning colors I liked its color reproduction. 5 stars, I really enjoy watching 4K/2160p movies on it. The games look great too, haven't tried Gaming mode, only using 4K/60fps and it's working out even for really hard and fast pacing games like Returnal (using Moonlight streaming over a gigabit ethernet). The cons are: slow menu (not a big deal), bad contrast out of the box, picture little darker than 3,600 Lumens.

Absolutely amazing picture. Bright, crisp, and the short-throw lens works perfectly in smaller spaces. Runs quiet, easy to mount, and handles gaming/movies/golf sim equally well. Worth every penny for a home setup. Used it on my golf simulator provided by gosport (highly recommend for the price) Lots of adjustability and customization on the screen. For the price compared to others it was totally worth it.

Disappointed with the Product and Extremely Poor Customer Support I was initially satisfied with the UHD35STx projector — it worked well for about 20 days. However, it soon started showing display issues, with constant green and red lines appearing at the bottom of the screen initially adjusted after turning on game mode on/off Shortly after, the projector began making loud noises, even when in Eco mode. Sometimes, it would make a sudden, blast-like sound when shutting down, which was alarming. I reached out to Amazon support, but the experience was extremely frustrating. They only focused on the return window and offered no real help or solutions. Despite the listing claiming “product support included,” there is absolutely no meaningful support provided. I’m currently not satisfied with this product and extremely disappointed with the overall customer support experience

Picture looked alright. I tried to watch football but the picture didn’t look so nice. The green of the grass wasn’t very deep or rich.
