Optoma UHZ35 Projector - 4K UHD Laser Projector for Home Theater and Gaming | High Brightness 3500 Lumens, Compact, HDMI eARC, Lightning Fast Games 1080p 240Hz at 4.4ms and 4K 60Hz at 17ms

Very pleased. Make sure you use fiber optic HDMI cables. Remote is an embarrassment. Fan is tad noisy. But overall it’s a compact well built unit.

So I ordered this to replace my trusty but tired Optoma HD20 after 15 years and decided to stay with the brand — and I don’t regret it. It was a drop in replacement and a significant upgrade. Brightness is excellent, color took minor adjustments for my screen. 1080p to 4K is great as expected but the real value was the ease of upgrade keeping essentially the same throw length. Yes, the remote control is on a par with cheap LED candles, but it’s gone in the drawer with all the others and my universal remote handles the new one just fine. For the price it’s hard to beat imo. (This is for the standard throw UHZ35 -not- the UHZ35ST, and it’s important to note that as of this writing Amazon incorrectly lists the standard throw UHZ35 projector option I purchased as “1080p”, when it’s in fact also a 4K projector similar to its short throw sibling)

I very much regret buying this now. The first problem I noticed right away is that the fan is super loud, constantly buzzing away. It's way louder than my many years old Optoma UHD60 that I replaced with this UHZ35. The second issue is that it can't focus the entire screen, with about 1/3 of the display or more always being blurry. That's super annoying too, as the fact that my UHD60 had gotten much worse about blurriness around the edges was a key reason I was replacing it. The most annoying this I ran into , though, is that they claim it supports 3D, but after 4 hours so far troubleshooting it, as someone extremely tech savvy (I program video games professionally), this projector does not actually support 3D in any meaningful way. 3D was a key feature I was using to select this projector, and it seems it be all marketing lies. The projector UI just stubbornly has the "3D" setting visible, yet disabled, providing no clues as to why. Based on my research, apparently it only can do so from a 1080p signal...and Windows cannot send it anything lower than 4k as the "active signal mode", regardless of whether you set the display resolution in Windows to 1080p. If there's no way to get a 1080p signal to this projector from Windows and the projector can't display 3D without that...it's not really 3D capable.

After owning three 1080p projectors, upgrading to this 4K Optoma laser was the best move for my home theater. The 3500 lumens are bright enough for daytime use, and it looks incredible in the dark. ​The Pros: ​Picture Quality: Exceptional 4K detail and color calibration options. ​Gaming: No noticeable lag; perfect for a gaming room setup. ​Throw & Zoom: The physical and digital zoom made fitting my screen at a long distance very easy. ​3D Performance: Active 3D (DLP Link) is amazing. Note: I had to factory reset once to get 3D to trigger, but it’s been flawless since. ​Build: It runs cool and the fan is impressively quiet. ​The Cons: ​The Remote: For a $1,500+ unit, the remote feels incredibly cheap (like a 50-cent LED strip remote) and isn't backlit. ​Lack of "Auto" Features: No autofocus or auto-keystone, so manual setup takes some patience to get perfect. ​Connectivity: No built-in Bluetooth. ​Bottom Line: Everyone who visits is floored by the image. You won't find this quality elsewhere without spending $2,500+. It’s the perfect unit until I eventually move to an Ultra Short Throw.

Claims to have ultra low latency, but fails to mention you have to go through a convoluted menu system to find gaming mode. Oh and you have to reboot it if you enable it, or it won’t work. Ok fine. However, you cannot use the screen resize in game mode. What? Why? If gaming mode is off, PS5 lags so bad it’s unusable, turn it on and the four corners are all messed up because it can’t support v and h resizing for some reason. Design flaw? It warns you on screen so they know about it. Then the cherry on top, it makes a loud buzz every time you turn it off. What gives guys? My last 4k optoma was lamp based, worked perfect regardless of mode, however it failed about 3yrs in. I don’t think I’d be frustrated if it weren’t for the marketing materials bragging about ultra low 4.2ms latency for gaming claim. Certainly wouldn’t have left a review. I wish I learned this sooner, had it for over a month now and I feel guilty shipping it back in a regular box for a refund.
