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

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.

I'm coming from an Electrohome 4100 (VGA) CRT, BenQ PB6100 (VGA), Optoma GT750 lamp-based 3d gaming projector (720P) lineage. I've projected on everything from makeshift dollar store shower curtains to elite screens. So I've seen bad and great and used these machines for thousands of hours for various purposes. :) My most current screen is a 180 inch Elite. / 4.5 Meters / 15 well pedicured Feet of awesomeness with maybe 1 - 1.5 gain! The most recent machine, the Optoma GT750 was my first foray into 3d. It did it extremely well. I put 4400 hours on the *second* lamp with some dark room viewing life left. It was pretty solid for what it did. I was happy until the last moment but just needed an upgrade as better resolutions are available along with new technologies. Laser and LED have had my attention for a while so thanks to Amazon for their great return policy and Optoma's recent 30+% sale, I jumped in to a "budget" model to start. I figured given the new tech, how could it be worse? SO far? After just a few days? BLOWN AWAY. Bright! CRISP! QUIET! I've got the Laser at 75% level with the lights on and everything looks fantastic. Lights on performance is deeply affected by the screen you use and light bleed from ambient surroundings is inevitable for the most part. But it is hardly noticeable here! I'm still awaiting the DLP-Link3d glasses to arrive to test that feature, but so far, soooooo good. The GT750 I used before uses an external 3d sync module and custom RF glasses that sync similar to blutooth. Each pair is roughly $100 USD. DP-Link uses a sync frame embedded in the video to control shutter timing. Similar optical characteristcs, however, and a LOT cheaper. I'm getting them for about $25 each. I will review the 3d performance later. I'm really hoping it is at least as good as what it was with the 750. I was a little nervous about the external power brick but it is high quality, thin and pretty light, a lot like the DELL laptop supplies 5 or 10 years back. Since I have the projector upside down on the ceiling, it lays on its base and held down with a little zip tie magic. This projector uses MUCH less juice, so a power brick makes perfect sense. And with how weird things are these days with power interruptions etc, I actually feel better about the power source being external & replaceable. We had a surge or two here that have zapped computer ATX supplies etc in the past. It's only been a few days but I have no buyers remorse as of yet, despite the much higher price over the last generation lamp-based devices I had. The picture is simply unbelievable to me! Perfectly rich color reproduction and overall brightness. I was expecting to just pop the GT750 off and pop this one on. Nope. The mounting bolt pattern required adjustment of the mounting arms (5 minutes) and 3 new VESA screws. The mounting screws from the 750 will not work. You need 3 M4- .70 X 10 VESA style machine screws to mount. Luckily I bought an extra bag when I was mounting my monitors to my desk stand. Incredibly, I had to change the mount location CLOSER to the screen by about 2 feet!!! This blew me away even more. This thing is seriously short throw. On a 15 foot 16:9 screen, at 75% power, in ambient light this thing is amazing to me on a 15 foot screen. I do wish there was more adjustment available in terms of trimming the excess off / blanking the sides of the screen where it bleeds outside the screen but this is more due to my poor set up. I could move it closer to take care of that, which I will when I finish my studio / theater room later this season. The 750 could cut the image on the sides to eliminate any of that. Again, it's been less than a week but in that week we watched a half season of "Lost" and the first season of "3 Body Problem" with incredible results. It was a lot of money ($2500) coming from the old Optoma GT 750 ($800), Canuckistanian Dollars, but it is worth every penny so far. I will report back after a 3-D weekend (Ready Player 1, Avatar 2 etc) maybe in a month or so.

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.

Very hard to use. impossible to adjust. Tech support is very condescending. Projector has to be tilted a lot to get a picture not too high. Optoma says use it on a table. Oh yes, everybody has a power outlet in the floor. Make sure you don't trip on the hdmi cable.

OMG I have been using projectors since 1999, several different brands and nothing came close to this one. The projection image is extremely sharp, clear, Brite and blacks are truly black. You really can’t beat this image. And it’s a short throw, meaning you do not have to have a very large room to get a big image. My projector is only 7 feet from the wall in projects a cinema scope image that is 14 feet wide.!!! Love everything about this product.
