That’s because it’s a preset meant for Turbo-Duo/PC-Engine games. It has built-in crop settings for that console. I don’t mind continuing this line of presets to cover other consoles.
So you can look out for Sega Genesis, NES, SNES, PSX and arcade presets in the near future. I’ll just evolve them from my current best or latest efforts which I tend to use for each console.
In the meantime, if you want to use that preset for Genesis/Megadrive, you’d probably want to set the NTSC Phase Mode to Auto, NTSC Resolution Scale to 1.0 and enable Genesis/Megadrive Luma/Brightness Fixes and the Megadrive Palette in addition to resetting any crop settings to defaults.
Update 19-12-2025:
CyberLab Megatron miniLED 4K HDR Game BFI Genesis Composite Sharp PVM Edition Epic CAR9x9x W4.slangp and CyberLab Megatron miniLED 4K HDR Game BFI NES S-Video PVM Edition Epic CAR9x8x W4.slangp added.
This should basically be what you’ve been waiting for? : )
4k, 240hz, RGB subpixel layout no white dompixel and not even “at least quadrilateral layout” or “damn triangular layout”, should just be win/win/win right?
VGA mode (the setting from Guest’s CRT Shader) should look amazing on a such a fine pixel density too at 27 or 32 inches.
From what I’ve been told 4K needs to be a minimum 32 inches, but I also have no hands on experience looking at 480p shaders to check.
This part seems interesting from the article you shared:
The panel also has an increased aperture ratio, which means that more of the pixel area emits light than before in order to enhance brightness – necessary due to the elimination of the white sub-pixels.
This part doesn’t auger well though:
LG Display said the Tandem WOLED sub-brand refers to displays that have the extra white light source in their pixel structure to enhance brightness, and will cover its larger panel lineup for televisions and monitors. Meanwhile, Tandem OLED displays lack the white subpixel and primarily cover medium and smaller panels used in tablets, laptops, smartphones and car infotainment systems.
However, the new RGB stripe OLED panel is clearly aimed at monitors
I wonder how bright these things are actually going to be. MLA would also be a welcome addition.
I’ve moved on from OLED for CRT Emulation primarily because I know how much better a brighter display can do the job and miniLED also does an excellent job on the blacks like the borders as well and there’s no burn-in risk.
I also moved on from gaming on monitors almost 2 decades ago. My current dream displays for CRT shader emulation are the TCL QM851G, TCL QM9K and TCL QM8K and these are TVs that one can actually buy today. They all trounce the LG G5 - the brightest OLED display today in peak and especially in sustained brightness, which believe it or not is one of the most important pillars of CRT Emulation, if not the most important.
You should definitely give it a go! It’s a gamechanger having retroarch shaders work seamlessly for any application. Been using it for old TV series and games like Deus Ex.
Hi CyberLab, first of all I want to thank you for your amazing work, and especially for your willingness to help. I’ve always seen you actively replying on Reddit, YouTube, and of course here as well. I’m more of a silent user, but I’ve been enjoying your shaders for years now.
Currently, I’m using a MiniLED TV (Samsung Q90C) that reaches close to 1500 nits… at least according to the Nvidia app. I wanted to ask you a couple of questions. I’m using your latest, most up-to-date shader, and I configure each emulator with its corresponding shader.
What confuses me the most is the following: in the shader parameters, you mainly recommend adjusting Peak Luminance and Paper White Luminance. Aside from those, should I be modifying anything else? I ask because in the past I used to change the resolution to match my display even though it’s not set to 4K by default and I also experimented with leaving RGB at 0. However, I noticed that the colors start to look a bit strange.
When I leave everything at the default settings 1080p and RWBG it actually feels like the image looks better overall. Maybe I’m misunderstanding something or doing something wrong.
Sorry if I didn’t explain myself very clearly; English is not my native language. Once again, thank you very much for everything you do.
If your TV is a 43" or 50" it has a VA screen so most likely BGR would be the correct subpixel layout for your display, however there have been VA displays with an RGB subpixel layout.
If it is a 55", 65", 75" or 85", it has an ADS (IPS) Panel and the subpixel layout is RGB.
You’re free to adjust the settings to whatever looks best to you.
@MajorPainTheCactus wrote something recently concerning setting Peak and Paper White Luminance. Also note that there are colour controls you can use to dial in the colour as you wish.
These things are like a moving goal post. Once you change one setting many other things can change as well. Also, try experimenting with the Colour Accurate/Mask Accurate setting. Some displays look better with the first, while others look better with the second.
Differences in phosphor choice, Mask, TVL and Scanline Dynamics can skew colour, not to mention just adjusting the Gamma or Paper White Luminance.
For me to better understand what is taking place, please include high quality photos demonstrating what’s happening.
