Testing CRT mode on unsupported displays - Full HD 120Hz 3D Vision
I know there are existing threads for specific displays and generic 1920x1080x120Hz. Also, people have had mixed results but I thought I'd start a topic where we can share results.
Today I tried 3d vision mode on a 2017 LG OLED display, a C7V. Most people are probably aware, but LG removed 3d support on the later OLEDs but added 120Hz support at 1920x1080.
I've been meaning to try this for months, but today I finally got round to testing this display in CRT mode 3d vision.
Unfortunately, the results were really poor. No flickering at all, probably due to it being an emissive display technology with no backlight, but horrible crosstalk and no good at all. I might try a different EDID or a custom resolution with different timing, but out of the box it's useless.
I'll have another play tomorrow, also I'm going to use the slow motion video on my phone just to see if it sheds any light.
*Edit* added Paul's projector! I've created my own subjective test scores just to get the ball rolling.
I would expect that a fully working DLP projector could score a 5, as long as there are no sync issues and the brightness is adequate. Appreciate brightness also depends on screen size and material (gain).
*Another edit* Appreciate that other passive displays can also work really well using advanced Migoto features. Maybe there's a way of incorporating that as well, although I've left them separate as there's nothing really on the market right now outside of custom dual projection.
So, on a scale of 0-5, with 0 being useless and 5 being perfect.
1. 2017 LG OLED = 0 (useless).
2. 2018 Optoma UHD40 = 4/5?

I have a Seiki 4K that would accept a 1080P120Hz input. but only was showing 60 frames. This was shown by a poster over at AVS forums using the UFO test from BlurBusters.
After a patch to the TV software, it no longer skipped frames. Once again confirmed by the UFO test.
Moral of the story...
some displays accept 1080P@120 as an input, but do not show all the frames. Confirmation can only be obtained via the UFO test.
This could be the issue you were observing on the LG.
Also, for anyone wanting to try generic DLP for anything, I posted an EDID over at 3D Vision blog that has it show up in the NVCP.
