Hi Paul and other optima 40/50 owners, what is the brightness when playing 3d games wiht your projector ? I have the benq 1070 and it's just too dark to enjoy fully.

However it's not as bright as Asus PG278Q monitor for example. Something else which could also matter is that I'm using a 1.2 gain screen so I should have a little light boost here. So an option would always be to just buy another screen to improve brightness.

FYI, using a 2.5:1 glass bead screen with a "3000 lumen" projector, but the colour wheel has a clear segment so the number is of course exaggerated. The results are OK to Good, being a similar brightness to a gaming monitor when the projector lamp is new and the screen is clean. I would assume the UHD40 would be about the same, as it has a RGBRGB wheel without a clear segment if I recall. On a normal white wall, it is too dim for my personal taste. If anyone is in the market for a glass bead screen, I would highly recommend it for gaming (the reduced FOV is a non issue because you are the only viewer).

[quote="RAGEdemon"]Thanks for the reply frank.binnendijk, When you said "the jump is big going from 720P DSR ([color="green"]2540x2160[/color]) to Native 1080P", did you mean "2560x1440", i.e. 4x DSR?

It seems to be a simple sharpening filter, wich is exactly what I want - are there different levels of power? 3DMigoto + Reshade is a PITA to get to work together; this feature alone might push me to seriously consider this projector [/quote] Hi Rage, no problem Always good to have more information. I did mean indeed 2560x1440 (4x DSR) The Ultra detail settings have 3 different settings 0,1,2,3 I noticed in Witcher when I turned it off the game was more blurry less detailed Increasing it the image become`s sharper and more details appaer (my opinion offcourse) Brightness wise it is a step up compared to the benq, I can now leave a curtain open and the image is visible enough. It is also a lot more silent then the benq. Also a handy function of invert 3D in the menu But offcourse there are also downside`s on it No SBS/TB for playing movie`s The ridicilous thing to buy a stupid emitter while u are using DLP glasses More ghosting if looking/sitting at a angle compared to the Benq Finding out how ridicilous specs for 4K DSR are, was not planning to play 4K DSR with a 980 though lol The lack of documentation in the box and the lack of documentation if it could do actually full 3d and how. Thankfully you guys where there to provide the information. Also if you are using a universal mount you have no right on warranty (well thats what it said in documentation lol) Still a huge step up (more then I expected) and very happy with it :)

Thanks frank.binnendijk, very informative. I'll keep it in mind going into the future. Very impressed by the sharpening filter; that one took me by surprise! As you said, I think it is a significant reason for your happiness with the projector as an added boost to its higher resolution, compared to your old 720p :) BTW, I have read that the 1080p native projectors such as the UHD40 work at 240Hz internally. It's a shame there is no available bandwidth on the chip to take advantage of that but certainly anything up to ~138Hz ought to work fine with a max pixel clock of 300MHz. Have you guys manually tried setting higher than 120Hz refresh rates? 125, 130, 135Hz etc... It would mean that even with 3DV, we would no longer be limited to 60FPS :) Thanks for the update @D-Man11.

FYI - I'm only attempting to test games in 3D Vision.

Here's what's working fine:

  • 1920x1080 @120Hz 2D
  • 3840x2160 @60Hz 2D using DSR
  • 1920x1080 @60Hz in 3D Vision
  • 1920x1080 @60Hz in 3D Top/Bottom
  • 1280x720 @120Hz in 3D Vision


Basically, anything in 2D or under the 1920x1080 @120Hz mark in 3D I can get to work as normal.


Here's what's not working for me:

  • 1920x1080 @120Hz in Native Top/Bottom (tested Trine 2)


Trine 2 was interesting, in that I got the projector in Top/Bottom 3D mode successfully in 1920x1080 @120Hz, but it had some scrambled scanlines and the screen was jumpy.
