RP5 uses that too.

To conclude the posts about the megatron shader on smartphones, I leave the link with my latest results and I came to the conclusion that for an appearance closer to a PVM on an amoled screen on my smartphone, it would be ideal to use the 600tvl. I only used the Sony PVM 2730 HDR preset and I changed hdr to sdr and 4k to 1080p, the rest I kept as default.

Using Dolphin I opened it up using Special K and applied sony megatron shader via SpecialK as a plugin, seemed to work fine

I just gave it another try and got it working. I think the problem is that for some reason I’d tried installing it as a DX12 version. I swapped Dolphin to Vulkan and installed Reshade as the same and that seemed to fix it. Some rendering APIs definitely seem to have some funky compatibility.

Why does the Mask look like that in Tate mode? Isn’t it supposed to consist of RGB triads? I don’t see any there.
Thank you for the work on this shader but I am afraid it is not working for me. I am using a samsung s90d qd oled and when I use any of the hdr presets the colours look completely washed out and tinted red. I have been messing around with the settings of the shader and in retroarch. I even deleted my retroarch config. None of this has fixed the issue. I thought it might have been the qd oled subpixel causing issues but I see the creator has posted using a qd oled with no issue so that doesnt seem to be the case. Hopefully someone here could provide some insight and help me enjoy this beautiful shader.

Make sure you have 444 chroma enabled. 422 or 420 chroma subsampling causes issues along those general lines.

Posting your current settings would help immensely.
What Peak Luminance and Paper White Luminance values are you using?
What Shader Preset are you using?
Definitely what @Azurfel said about your color format.
Do you have HDR enabled in Settings–»Video–»HDR?
HDR On:
HDR Off:
You can also try my Sony Megatron Color Video Monitor preset packs which might just happen to have default parameters which might work better with your TV out of the box.
Don’t worry if it says miniLED or whatnot, all will work so try them all.
These guides might help:
Especially this updated one:

what’s the “sharpness” setting at on the tv, try messing with that

I can report back that I have just tried your shaders now. Some of them looked good and others were having the issue. I’m guessing the ones that I’m having an issue with are based on these megatron shaders. Its a shame because I really love the look of these megatron ones.

In Nvidia control panel it was set to RGB before. I changed it to ycbcr444 but that did not fix the issue. Presumably if thats set and the tv is accepting the signal then it should definitely be 444 chroma. Looked at an rtings.com chroma test image and that looked perfect aswell. Thanks for the idea anyway.
Thanks for the reply. I’ve got hdr enabled in windows and retroarch. Attached are my settings. Everything default except peak brightness adjusted to my displays capabilities. Using d3d12 driver. Tried vulkan or d3d11 but didnt make any difference. Typically just testing the default hdr preset but have tried pretty much all of the others including sdr ones. I tried a lot of non megatron shaders like royale and they are working fine. I will look into your shaders now. They look good but looks like a fair bit of setup to do so I will update with how those work out.

I see you turned up the Peak Luminance here but do you know that you also have to turn the Paper White Luminance up as well.
In any case, this menu is not where you are supposed to adjust Peak and Paper White Luminance settings for Sony Megatron Color Video Monitor Presets.
You need to do that in the Shader Parameters.
The Peak and Paper White Luminance values in the Shader Parameters override these settings you have shown here. These settings here do nothing when Sony Megatron is in HDR mode.
These settings in the RetroArch Menu are for setting Peak and Paper White Luminance values for other Shaders which don’t have those controls built-in.
The instructions for Sony Megatron Color Video Monitor usage can actually be found within the Shader Parameters menu itself.
Also be sure that Windows (or whatever) OS you’re using is set to output RGB 4:4:4 Full. No Chroma Subsampling, although you might be able to get away with it if using Shadow Mask Presets like my W420M presets or very low TVL Aperture Grille Presets.
Generally these shaders operate down to the subpixel level and you need every subpixel to be independently addressable in order for things to look right.
If you haven’t done so already, be sure to update your Slang Shaders using the Online Updater.
I managed to figure out the issue. My tv had my pc set as a console input for some reason. After I set it as a pc the colors were fixed for all the megatron presets. Totally bizzare that was causing it. Anyway thanks for your assistance. I’m very happy with the shaders now. They look sufficiently bright in hdr mode even with bfi turned on.

All that and no pics?? Lol…It makes sense though, HDMI 2.1 ALLM and automatically defaulting to less than RGB 4:4:4. On many TV’s this is only available in PC Mode.
On older LGs we had to change the input label to PC to enable this and also enable HDMI Deep Color.
Glad we could help.
Try out all of the preset packs if you can and experiment with different “Display’s Subpixel Layouts” and feel free to give feedback as to which ones loom best for your display and also it would be nice if you can share your Peak and Paper White Luminance values for future reference.
Enjoy!!

Sorry for double posting. Having some issues with waiting for approval on messages since this is a new account. Will delete those posts now. My photography skills aren’t the greatest but here is a picture. It looks a bit washed out but I can assure you it doesn’t look like that in person. This is with BFI enabled and you can definitely tell it is still plenty bright on the QD Oled. I kept 1260 for peak brightness and while using 240p suite I found that I could get up to 800 paper white while still seeing all the color steps on the color bars test. Not sure if thats the most scientific approach but it seems to have worked out as games still look reasonably accurate to my eyes.

Thanks for sharing! Which preset is this?
I’m glad you got it sorted out. Sometimes less is more, meaning you might see more details being preserved at lower Peak/Paper White Luminance values to as bright as they need to be and not necessarily their maximum attainable values.
For better photography, you can try Manual/Pro mode, dark room, stabilized camera, Shutter Speed 1/60 (NTSC) or 1/50 (PAL), ISO between 50 and 250 depending on if you want to get the true to life brightness or if you want to capture details in dark and bright areas, With balance - 5000K or whatever looks true to life, Focus - Manual.

That is the PVM 2730 HDR preset. Definitely one of my favourites out of the set. I think 600 tvl is really a sweet spot for seeing the mask but still having a clear image.

You should definitely try out my preset packs. You’ll 've in for a treat. Also I forgot to mention toggling the Mask Accurate/Colour Accurate Parameter can have a profound effect on the colour on certain displays.
Yes, I agree that 600TVL is a sweet spot lower TVLs tend to have the Phosphors “spilling” over the edges of fonts and graphics sometimes because they can make things a bit too chunky.
