Optoma UHD 35 & 38 Review - Ultra low input lag 4k gaming projectors TESTED. 4.2ms @ 240Hz!!

[@whackstro5184]

I like how they take time to inform people on the context of some specs and the diminishing returns that may or may not be present. Like the "unless you're an E-sports professional, it shouldn't make a difference," comment.

[@andylopez6393]

Wow projectors have come a long way in just 3 years. I bought a Optama UHD 50 for $1400 after tax. 2,200 lumens, 60hz, and lag is around the 20ms I believe. Can’t wait to upgrade but most likely wait for the price to drop more.

[@ScanComputers]

They definitely have come along way! What upgrade would you be looking to get? -GH.

[@isaachunt5799]

we just bought one to replace our 10 year old benq w6000. wow what a machine. so bright and colourful. amazing. highly recomended

I'm thinking about getting it. Is the projector huge about the same size as the original Xbox?

[@mr.electronx9036]

Big Differenece between UHD30 & UHD35...4,20ms input lag OMG!!! Im very impressed what todays Projectors can do. Especially Projectors under $1000 (1000€). For about 3 Years ago, you couldn't find a proper one under $2000...

[@bovineox1111]

Great review. Did just miss a key point I think, at least I did not hear it, that when in GAMING mode, the HV keystone and other geometry adjustments are turned off, so you need to mount the thing square on. It is a bit disappointing but also understandable - the picture manipulation will introduce lag. These functions will also eat into the resolution so while it's a pain, mounting straight on (as I plan to) and doing without, will give me better IQ and access to the fast gaming modes.

[@ScanComputers]

We did reference the keystone but not with regards to the Gaming mode. You are correct though, in the gaming mode they will not work so its essential to have it mounted square.

[@bovineox1111]

@@ScanComputers yes you referenced the keystone but missed the key point. It's pretty significant for gamers who would want to know that they cannot use any geometric adjustments with gaming mode enabled is all.

[@BigLebowski2000]

true although also with game mode off and using a bit keystone/4 cornering I did not have much lag/input lag. It is such a great beamer.

Thank you very much for the detailed review. Would like to see the UHD 35 side by side with the UDH38 to see the difference in brightness.

Unfortunately we couldnt get hold of both at the same time for testing. 400Lumens extra should be noticeable, mainly in a more brightly lit environment, but less so in a darker one.

[@Goten.2752]

Is the 42 or the 35 now better? It looks like the high brightness in the 35 makes the details downgrade

[@audiovisualkart]

Thank you For reviewing, I am Dealer. The Optoma UHD35+ is a high-performance projector that is designed to deliver bright, vivid images with excellent color accuracy and contrast. It features a native resolution of 3840 x 2160 pixels, which is four times the resolution of Full HD, and it is capable of displaying HDR content with a wide color gamut and deep blacks. The UHD35+ uses a high-quality DLP chip and a bright lamp to deliver up to 3,600 lumens of brightness, which makes it suitable for use in a wide range of lighting conditions. It also features a range of advanced features and connectivity options, including HDMI 2.0, HDCP 2.2, and USB power, making it a versatile and capable choice for a wide range of applications. Overall, the Optoma UHD35+ is a high-quality projector that delivers excellent performance and versatility, and it is definitely worth considering if you are in the market for a high-quality projector.

For me I'm going to stick with the 42 for now but if I was buying one new then I would go for the uhd 38 as I dont need the setup stuff and the extra brightness and 2x hdmi 2.0 ports would be worth it. Great and fair review Scan! These videos should get more views for sure!

Then try play a 4K picture in Enhanced Gaming Mode. You will see that the UHD30 and UHD42 cannot play back the picture in 4K but reduce it to 1080p. This is a problem with the Texas instruments chip from last year and is not mentioned by Optoma. Believe me, I had many conversations with Optoma until they finally recognised and confirmed the problem.

please help: I experienced two negative things with the beamer. First of With certain games I have static red snow on screen and there is a slight yellowish tint on the far right side of the screen. If I zoom in then it is out of sight, but still there if I zoom back. Could this be the long hdmi cable? Or is it a faulty beamer? Thanks for any help!

[@ericdorfler6454]

the contrast in the picture and the sharpness are better with the uhd 42, as I can see, this can still be adjusted with the uhd 35

[@ScanComputers]

There was no difference in sharpness between the two models so that must be something from filming them. Contrast overall on the 35 was better due to the brighter whites and light colours, but there was some loss of colour strength at default settings. Overall the 35 offered a better all round ability if you changed the settings but it was quite close.

@@DrEdwardJames it's not all bad. Because the projector projects bottom up and when ceiling mounted that means top down, if you drop the project 60cm or so the height up the wall is not so bad (though have yet to set it up, so this is in theory). So if you mount it straight onto the wall you won't need the keystone adjustments, which, from my research since, reduce the image quality quite a bit!

All optoma projectors use Active 3D glasses. in fact pretty much ALL home projectors are active. It was only TVs that had options for passive. Cinema projectors actually project 2 separate images through separate lenses to allow passive glasses to work and thats very costly to do.

This will depend on a number of factors. If the screen is in direct sunlight then you will have a washed out image. If its in a darker area that isnt in direct sunlight and your image size is less than 120 inches then it will likely be quite watchable.

[@GAPOWERade]

Are they better than the 50x aside from the contrast ratio?

[@ScanComputers]

Yes they are better in some ways but not all. The UHD 50X is the same model as the UHD 42 (US and UK markets have different model numbers but are the same.) so what we said stands for that. Essentially much faster menus without the long wait, Gaming mode now works in 4K without reducing resolution and overall input lag times are down. However 35 and 38 lack the 1.3x zoom and vertical adjustment that the 50X has. they also have a longer throw.

[@GAPOWERade]

@@ScanComputers I didn’t know that the 50x reduced the resolution??

[@ScanComputers]

@@GAPOWERade its well documented online, but you can see that the resolution is lower when you turn on gaming mode in 4K. Unless it was fixed in a firmware update for that model. If its not then you are better to leave gaming mode off when in 4k mode. Input lag is about 25ms without so its still very good for general gaming.

[@niketariq]

Is it worth to upgrade my tk800m to optima uhd38?

If you already own the TK800M then its probably not worth the upgrade unless you would really benefit from the extra brightness and the gaming mode. If these are not required then probably best to leave it until a further generation

The actual measured input lag on the UHD35 is 15ms, not 4. Completely embellished by Optoma. It's advertised contrast ratio is also wildly over promised. Do the research and it's easy information find.

Looking for an answer to this as well! Anyone? Even compared to the TK810 or the W1720 (even if it has lower lumens, the colors seemed promising)

[@ScanComputers]

We havent tested the TK800M ourselves so cant offer a comparison. The optoma certainly offers more brightness and the gaming mode so if either of these are important then the Optoma should be better. It also (we think, you may have to check) uses the older 0.47 Ti chip which could suffer from the same slow mode changes which are massively improved on the newer Optoma.

Input lag at 1080p 240Hz is 4.2ms. At 4k 60Hz its 16ms. With this projector in gaming mode its mainly limited to the frame rate :)

[@TheDearRecorded]

Between these Optoma UHD 35 or 38 and the BenQ W1720 or BenQ TK800M / TK810 which would you recommend for better black levels, colors and movie viewing? I will be using it in a living room (non-dedicated viewing space) on a white wall and there is a bit of ambient light but blackout curtains to cut the light. Will be using it mostly for movies/series and some gaming on a Nintendo Switch, mostly at night. I was almost going for the BenQ but having owned an Optoma (HD20) in the past and literally never having a problem with it, I'm still looking at options from Optoma Is there any other projector you recommend in the below 1300 Euros category? (classic/long throw only)

[@ScanComputers]

Hi, We havent tested the BENQ models ourselves so cant offer a comparison. However it sounds like the OPTOMA is the right model for you based on what you have said. The high brightness will really help in your room to get the colours across. Usually in rooms with moderate light control and lighter walls/ white ceilings it is the blacks that suffer the most due to light refracting around the room so you are better off with more brightness than better blacks. It may also be worth considering making the wall grey rather than white to help with this.

[@apfelschorle1988]

I don't know. 240hz without VRR is missing an important part.

[@ScanComputers]

Its definitely something we would love to see in future for sure. The current Texas Instruments chip isnt capable so it could be a few generations before we see it. However turning on V-Sync or Fast sync (Nvidia) does fix the issue and when you are at 240Hz the increased lag from those options is imperceptible. So there are options toi get a great experience.

Still not good enough for me to bother. I want 4K, not 1080p. I don't need 240hz. I want 120Hz at 4K at 10ms or less and then I am happy. It needs to be native 4K, HDR with VRR and aforementioned 120Hz at 10ms or less input lag. Also bright enough and wide enough color gamut and black level. Is it asking a lot? Perhaps but this needs to beat TVs that can do all of that with a stronger picture. So just larger size isn't enough. Furthermore at those very large screen sizes even native 4K is hitting a wall.
