Today, Optoma announced two new, high brightness, 4K gaming projectors available for purchase from authorized dealers, the UHD35 and UHD38. These projectors expand on the UHD30 that came out last March. Both are capable of a 240Hz refresh rate for smooth motion in games and have low input lag—an attractive feature for gamers.

The Optoma UHD35 and UHD38 projectors use the same chassis.

The lowest input lag for the UHD35 and UHD38 is only one quarter the already impressive lag of 16ms that the UHD30 was able to achieve at 240Hz. The new projectors are spec'd at 4.2ms with 1080p/240Hz signals. At other refresh rates, Optoma says the projectors are capable of 8.9ms at 1080p/120 and 16.7ms at both 1080p/60 and 4K/60.

Both projectors use Texas Instruments' UHD-resolution (3840x2160) DLP XPR display technology with a traditional lamp light source and an 8-segment (RGBWRGBW) color wheel. Optoma specifies a light output of 3,600 ANSI lumens for the UHD35 and 4,000 ANSI lumens for the UHD38. In Dynamic Black mode, the lamp has a life of up to 15,000 hours. The projectors are compatible with both HDR10 and HLG high dynamic range content. Blu-ray 3D is also supported.

The projectors look identical and share the same collection of inputs and outputs: two HDMI 2.0 inputs with HDCP 2.2, an optical audio out, VGA in, USB that can supply 5V of power at 1.5A (enough for a streaming stick), 3.5mm analog audio input and output, a 12V trigger, and RS-232.

The Optoma UHD35 and UHD38 are available now for $1,299 and $1,399, respectively.

This is so close to being a perfect projector spec wise for me. I would love to see an alternative lamp with a longer life, but as it stands this looks amazing on paper.

Michael, we'll be working on a review of the UHD35 shortly.

Why no HDMI 2.1?
Jay Molinuevo Posted Mar 24, 2021 9:35 AM PST
Will either of these come with bluetooth enabled to connect to a sound bar?
Rob Sabin, Editor Posted Mar 24, 2021 11:42 AM PST
Bluetooth is not a feature of these projectors. They do have optical audio outputs for a wired connection.

Not seeing much difference in these projectors to thee highly forgot Hd29hst which has 1080p 120hz and 8.4ms response on ehanced gaming mode supports 4k at 60hz at 16ms response time and is also short throw no big leap by optoma

Is this really 4k or pixel shifted? I wish they would stop calling pixel shift 4k. It is not. It is 1080p.

When will we see a long throw HDMI 2.1 projector with 4K 120Hz, Freesync Premium Pro, and less than 10 ms input lag? We also need a separate HDMI for eARC. The HU810P was looking good, but missed the specification marks for gaming. I've requested directly to LG that they make a new version of the HU810P with those gaming focused specifications - they've passed it along to their marketing department. My wallet is me the projector.

1. There is no HDMI 2.1 because it doesn't need it and never will. 2.1 only necessary for 4k120 which these nor any other pj can do. That would require 480 pixel shifts a second not the 240 the tech is capable of. 2.The HD29HST can accept 4k signals but only displays them at 1080p. So these projectors are not even in the same class. 3.Stop complaining about pixel shifted 4k. There are 8.3 million addressable pixels in the image, who cares how it achieves it. And no, it is not 1080p. 1080p is 1080p. It is currently not feasible to cram 8.3m pixels on a dlp chip the size of your thumbnail. Sure you could use a bigger chip as does Sony and JVC but the bigger chip needs bigger optics and bigger optics need a bigger housing and when you add all that up you're at $5,000. Pixel shifting is the only route to affordable 4k pj's right now and they look great.

4. If you want something to complain about in projector's how about HDR? I would have loved to see dynamic tone mapping added to these Optoma's!

So we are all clear on the facts. Xbox Series X has Freesync Premium Pro and offers games that are 4K 120Hz. This is happening now.

Freesync Premium Pro works with HDR.

The consumer ask is for a projector that can perform 4K 120Hz with Freesync Premium Pro. eARC should be on a different HDMI port.

Consumers are ready to buy a projector that can accomplish this.

I hear you, Benevolent. Right now those are definitely on gamer's short list for features (including mine), but we're still likely a little ways away from all of that being available on one projector. At the very least, on a projector that would compete in the same price range as these Optomas.

We also have yet to see games that even fully utilize the processing power of the XSX/S and PS5. While there are some titles that are capable of 4K/120 in some way, it's usually only portions of the game (for instance, Gears 5 will only do it during multiplayer iirc). These titles that bridge the gap between old and new consoles are never able to fully capitalize on the new (Cyberpunk 2077 is the most famous current example). I'm excited to see games later this year that are coded primarily for the new consoles that will better utilize their processors (Horizon Forbidden West being at the top of my list).

Basically what I'm saying is, we'll get there. Probably within the next year. It's not that the companies are unaware of consumer's interest in those, it's that they're still getting it to work fully in a package that they can sell. I mean, Sony even released their first HDMI 2.1 gaming-centric TV without any of the gaming features enabled. Last I saw, they still haven't added ALLM or VRR. Seeing LG and Vizio getting it to work should at least give us hope (especially LG since maybe it means an LG projector isn't far behind).

Would love to see a projector that has the capability to do 4k60 with HDR at 4:4:4 chroma sampling. That just can’t be done with HDMI 2.0b as it requires 24 Gbps and HDMI 2.0b maxes out at 18Gbps. It sure if there is any way to make this happen without HDMI 2.1 implementation.
Paul Posted Mar 31, 2021 12:57 AM PST
We all know the Hd29hst is only 1080p but that's the only difference between it and these new projectors when it come to input lag etc basicly the same as Hd29hst has 1080p 120hz and a very low response time (8ms) and is £300 pounds less and is short throw also

Its been close to a month since this news published. How soon we can expect the product detailed review? Thanks in advance.
Rob Sabin, Editor Posted Apr 19, 2021 8:02 AM PST
We have a sample of the UHD35 in house and are working on the review.
