Optoma UHD42 Beamer

[Lundamyrstrollet]

So, there it is, the successor of our beloved UHD 40/50, friend of mine has bought it and the UHD40/50 edid mod also works with this one flawlessly....Had also (as my Optoma HD29H) TaB and SbS even with the edid Mod... So, i assume, ftP (~1500 Bucks) its the best now for 3D Vision.... its a "4K" Shifter/ native 1920 x 1080 via 4K DLP Shift 2nd Generation without Lightborders/240Hz native DmD with an even better Input Lag*than the HD27HDR (US)/HD29H (EU).
And with 3400 Lumens noticeable brighter as the UHD40, ideal for 3D... Wish i had the Money and Ampere Cards with injected 3D Vision Drivers )


*InputLag 4K@60Hz: 25,8ms
InputLag WQHD@60Hz: 23,8ms
InputLag Full HD@240Hz: 15,7ms
InputLag Full HD@120Hz: 18,2ms
InputLag Full HD@60Hz: 23,8ms

Way too much for me, I'm still holding to my benq w1070, it's sad that TVs get ridiculously cheap really fast, but projectors won't go down no matter what, even 2018's UHD50 still costs 1000 euro here.

Does look nice, great 3D plus a 4K option for 2D Movies etc.. I am currently using the short throw Optoma 1080HDR with the EDID.

I am now waiting for new Optoma projectors to include HDMI 2.1. I wonder if 1440p 120hz could be an option in the future with HDMI 2.1, that would be amazing!

I've got a uhd30 *seems to be the uhd 40 without the shifting lens) - it fails to work in 3D play because the vertical convergence is off by about 5%. I'm wondering if you could help me get my projector to work as a 3D Vision ready monitor.

What does that even mean?

Anyhow, try this post/thread, it may help.

Thanks, that's a bunch of helpful info. The vertical convergence issue was that the Left eye was being shown about 50 pixels below the right eye. I patched my drivers using the fantastic automatic patcher, and was able to run in 3DTV Play without the vertical offset, however 3D TV play is locked to 1080/24p, and the drivers complain if I run games at 720/60 (by asking me to set to 720/60). I'll be reviewing the post you shared. Thanks!

I've got 1080p/120 working by following the fixes in that thread (although I had to find the downloads separately) - Optoma_UHD_40_DSR.zip installed with the cru-1.4.2.zip - restarted my computer, and now I've got 1 3D input and one 4k/60 input. Which is exactly what I hoped for when choosing the projecting. Thanks so much!!

[RAGEdemon]

Well done!

I might wait for HDMI 2.1 as well; it looks like my old projector has lasted me 10 years - at my seating position + nvidia / reeshade sharpening + 4x DSR to 1600p, it's still pretty good, though obviously showing its age

The optoma UHD42 is now out, https://www.amazon.fr/Optoma-vid%C3%A9o ... B0862DSSYN and normally has a good chance of being 3DVISION compatible. The 3D options offer as choice: SBS, TaB, Frame packing and Frame sequencial in 1080p/120hz. If someone tests it, you will have to tell us if it works in 3Dvision !

Great news! So we have 3 ultimate projectors for 3D Vision now:

• Optoma UHD 40 / 50
• Optoma UHD 42 (has very likely another model number in USA and Asia)
• Optoma HD29H / HD27HDR

I guess without the EDID override the projector was detected as a 3DTV Play device?

[puzzabug]

it's the HUD 42 / 30
Without the EDID it's a 3DTV play device.

It's nice and bright and when you turn off the color enhancements, the color looks nice as well.

UHD 30 und 42 are both available in Germany. So these must be different models. They differ 200€ in price. Not sure what the difference is except a slightly other lense. Both support 240hz. Seems not really worth paying the higher price for UHD 42.

The American model number seems to be UHD 50X.

Difference are afaik the other lense you mentioned and a "smaller" Lensshift... The UHD 42 was available in mid/end April in Germany for~1200, so theres no reason to buy the UHD 30, totally agree with that...
The 3400 lumens are only achievable with a RGBWRGBW Color Wheel, so the Colours are not this great as DLPs with a RGBRGB Wheel, this has to keep in mind if you come from a BenQ W1070 for example.... After half a year im satisfied with my HD29H, slightly worse colours after some Calibration, but esp. in 3D far much better Contrast and Brightness imho, after nearly 2000 Lamp Hours roundabout the same Brightness as my old 1070 with a new Lamp...

Has anyone been able to test if the Optoma UD42 is 3D Vision compatible ?

Has anyone been able to test if the Optoma UD42 is 3D Vision compatible ?

Isn't that exactly why the OP created this thread, the answer is in the first post?

Hello Russel,

Thank you for your answer !

Indeed I hadn't seen that people had already tested it for 3d vision but I was thinking of a more thorough test. I would have liked to know if the implementation of 3D was the same as on the UHD40 (mix between DLP glasses and 3D Vision receiver) but a priori I think it is the case. We have almost no details on how this beamer works or on the quality of its image, but I guess very few people have tested it.

There was a lot more enthusiasm for the release of the UHD40/50 (it was the first 1080p VP) and I thought that the release of the UHD42 would interest more people. In 2020 the last bastion of 3D, it is the beamers because I don't believe that there are other products released in 2020 that are 3D Vision compatible.

Hello, i'm interested in this projector too, but i don't have a 3D Vision Emitter to unlock "Generic CRT" mode like Paul Dusler described.
With my Acer H6518BD (1080p/24Hz, 720p/60Hz, 3DTV Play) i can get 1080p/30Hz by changing "stereoviewertype" to 1 in "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\NVIDIA Corporation\Global\Stereo3D", if i'm right this activates frame sequentiel output.
Does anybody know if this works for the UHD42 to get 1080p/60Hz 3d?
I searched a lot but couldn' find anything helpful, sorry if i'm missing anything, thanks in advance.

[3DNovice]

Optoma UHD 50X here, just got it.

Small problem, I should have gotten a short throw, I can only do 120 on my 140 screen, dooh!

OMG, this thing really dumps out some heat.

Anyhow to answer this question from another thread.

Thanks for posting and also confirming that the new UHD30 works. I believe the UHD30 is the EU version of the UHD50X, which supports 240hz input!

IF you have time, tt would be really interestring if you could try and create a custom resolution in the nvidia control panel of 1920x1080x240Hz and see if it works.

On the thread over at AVSFORUMS (https://www.avsforum.com/forum/68-digit ... tor-4.html) Mark Rejhon @ Blurbusters was really keen to get more information on how that mode looks as well.

A 1080P@240 resolution already exists in the NVCP, under the "PC" resolutions. It comes in at 559.4400MHz, I'm not sure what fat they trimmed to reach this, HDMI 2.0 has a 600MHz limit. They may have trimmed the porches or lowered the color bit-rate, dunno.

1080P@240 CVT Reduced Blank 32 bit comes in at 606.5280 and will not display.

I tried Rise of the Tomb Raider and it looked good, but I couldn't test any further because the signal kept dropping out. Perhaps it's the HDMI 2.0 cable that came boxed with the PJ or my Asus 2080ti GPU, Dunno. The PJ input did show 240Hz being output to it though.

I'll investigate further, if I have a chance. I leave out Monday before dawn and am typically gone 6-8 weeks for work.

Edit: it does show 32 bit as the color @240Hz in the NVCP

BTW, anyone looking for the 120Hz generic CRT EDID, it's in the 2nd post of this thread

Curse you Nvidia for destroying the old forum threads and their relevant links/downloads, you deserve a razzy award for worst forum design ever implemented.

[3DNovice]

Using 1080P@240Hz, I kept getting dropouts. I tried a HDMI 2.1 certified cable from Club3D (CAC-1372) and the issue was still present.

I then tried the Club3D cable in conjunction with DP to HDMI 2.1 adapter (CAC-1085) and no longer had consistent drop outs, except when switching resolution or primary displays, but it quickly recovered.

But using the adapter, I was no longer able to select HDR for whatever reason, the option wasn't even shown in Display settings anymore. I do not think HDR is HDMI exclusive, I believe that monitors using Display Port, also support HDR. Dunno

I've got 1080p/120 working by following the fixes in that thread (although I had to find the downloads separately) - Optoma_UHD_40_DSR.zip installed with the cru-1.4.2.zip - restarted my computer, and now I've got 1 3D input and one 4k/60 input. Which is exactly what I hoped for when choosing the projecting. Thanks so much!!

I have the same exact projector (Optoma UHD30), but after installing the Optoma_UHD_40_DSR.zip EDID override using cru-1.4.2.zip I am left with 3D Vision Discover only. I do not own a 3D Vision Emitter, is it necessary?

Or maybe you had to set something in projector settings? I tried putting it into 3D mode, but still I get only red/cyan anaglyph mode.

I may have had the USB 3D glasses installed at that point.

Thanks for a very quick reply!
Do you have the original ones, or you could recommend some replacement?

I have the USB ones, you can get an emitter on ebay still. Nvidia locked using the 3D functionality (even for crts and other things) to having an emitter. I'm pretty sure this is how it worked for me.
