Good thing my CyberLab Guest Legendary Preset Pack has only 1 preset (out of 48) which uses Mask 12, which was only added less than 24 hours ago.
Very good.
A picture paints a thousand words.
Hmm, while I’m glad you’ve gotten things to look good on your setup, if you look around this thread, you might notice that one of the signature characteristics of CyberLab Death To Pixels Presets is being able to go straight up to the screen and see the RGB phosphors in all their glory.
This same pattern would look very different on different panel types depending on subpixel layout. It’s like you’re asking me to translate something which is visual in nature by using theory and science, while I would much prefer to see what the output actually looks like on the particular display in a practical sense, especially with me not being an expert on subpixel science.
More theory but no testing, where are the macro photos which would make this all easier as we would see what is happening with the alignment and subpixel order e.t.c.?
I have no idea. Is this a screenshot or photo? Scaling settings can affect things like that. Are you using Integer Scaling on both the X and Y axes?
I don’t know what any of these Masks look like off hand so I’ll have to refer to the CRT Guest Advanced thread or load up a preset and look at them myself. I know that one of them should be a B&W Mask so yeah, that should be subpixel agnostic.
I’m not trying to pressure or force you to do anything especially since you indicated that for you, taking some photos of the screen showing different known RGB subpixel mask patterns may not be as simple as one might think but I do think that this path seems like beating around the bush and going down a long winding road of workarounds in order to get these things looking good on 4 Stack BWRG Tandem WOLED displays which have been on the market for well over a year now.
I recall when I first became “subpixel aware” when it came to these things, it was thought that the only subpixel mask which could work properly on WOLED displays was the B&W Mask. Even Sony Megatron Colour Video Monitor had a B&W Mask. The more I learned and observed, the more I tested and researched. Until I came across a post by @nfp0 where they said that they used Mask 13 (at the time) RRGGBBx, Size 1 for 4K.
Previously I was using Mask 6 (RGB), Size 2 (RRGGBB) and I’m not sure it looked correct on my RWBG WOLED from the perspective of what a subpixel aware CRT Shader Mask is supposed to do, which is mimc a real CRT’s Phosphor and Mask structure/appearance as closely as possible on a modern display.
This led to the creation of the “OLED Subpixels How Do They Work” thread because I realized how badly some of the masks looked on my WOLED display and wanted to see if better could be done. Through documentation, trial and error, a little luck and sheer determination, I realized that Mask 12 RRGGBBX with the BGR layout (XRRBBGG or RRBBGGX) finally gave a near perfect phosphor triad with excellent alignment.
Prior to this I enjoyed CRT Shaders on my OLED very much but they didn’t look quite right when right up to the screen. I even experienced this when I made my CRT Royale preset pack because that uses exclusively RGB layout masks, of course Hyllian has now made a BGR version available but we now know that even this wouldn’t work for RWBG WOLED as it requires an RBG subpixel layout.
This is ironic because CRT-Guest-Advanced never “advertised” or documented an “RBG” supixel order mask as being available so it seemed like a mere coincidence that that was the missing link. The evidence adds up as well because before my advocacy and inclusion of IV OLED presets, the consensus among the CRT Shader crowd was that WOLED could not be properly supported due to the white subpixel getting in the way of things.
Just to demonstrate how accidental this might have been, Guest.R attempted to update the “BGR” Subpixel layout for improved alignment and it completely broke RWBG support. Things went from something that looked like CRT phosphor triads to the mangled mess it used to be before. I mentioned it to him and he kindly and promptly reverted the change.
Right now I’m having some issues using “BGR” Mask Layout 1 on my TCL QM751G which is supposed to be BGR so I’m actually using RGB Mask Layout 0. I know very well not to bring it to Guest.R’s attention before I have gathered all of the requisite photographic empirical evidence and formulated exactly how I’m going to describe my “issue” and what I might want to ask him to do about it. I know that I most certainly need to start by verifying the subpixel order of my display on my own as although the model has been tested and stated to be BGR, who knows, maybe my size uses a different layout? Only proper testing would show. I’m having fun though the emulated phosphors do look “RGB” with proper alignment although the slot masks sometimes look a little strange using the naked eye, they look like the horizontal slot isn’t going straight across, it looks like the slot is slghtly higher over the red subpixels. It could be an illusion though. Maybe glasses or some macro photos might enable us to better observe exactly what is taking place.
One thing for sure is that “BGR” (RBG) Mask Layout 1 does not look correct on my current display.
Of course if only finer masks with higher TVLs are your cup of tea or if you never go right up to the screen to peep at the RGB phosphors you might think that everything is above board which is exactly what happens with my CRT-Royale or my older presets which used Mask 6, Size 2 on my RWBG WOLED display because this is not something you can see with the naked eye at typical viewing distances. So ignorance is bliss and I think that this is what is happening with the vast majority of users who are buying OLED displays for CRT emualation because they know about OLED’s fast pixel response times and their true blacks and perfect viewing angles. They might know about the CRT-Beam-Simulator as well.
Most of them may not know about subpixel mask emulation and what it entails or requires so they might go out and purchase a QD-OLED display thinking that they got the best of the best tech not knowing that QD-OLED is actually much worse than RWBG WOLED for subpixel aware CRT Shader Emulation and they may not know that OLED’s may not be the best displays for accurate CRT-Shader emulation due to their relative lack of brightness compared to other technologies.
