Do you know exactly what using the srgb_framebuffer does? It seems like the gamma function used to get srgb to linear is not a straight gamma application.
I know that using it, the colors don’t loose precision. And the results of using gamma in and gamma out in different passes now are identical to using both in only one pass.

It is kinda hard to show how a preset look on a certain tv, but I habe tried with this image. Still not correct, but close.

Finally posting here a link to my ReShade VHS setup. It contains both the Blurry/LowRes and the Clean version in 16:9 and 4:3 aspect ratios (labeled as 1920 and 1440 respectively).
Some screenshots (LowRes version) :
Clean version :
You’ll have to use Res-o-matic to get 4:3 in emulators like RetroArch or Dolphin on widescreen displays!
Without Res-o-matic :
With Res-o-matic :
This was made on a 1920x1080 monitor. So it may not work as expected on other resolutions! DM me if you need help with this (or anything else related to this shader).

Your crt screens were that blurry in your memories?!
Not in my case. Though I’m sure some old crt TVs were like that.
Anyway, if it isn’t your case too, there are other sharp presets inside the package.

One of the cheapest LG displays and a weird screen from China. 
I was wondering if it would be possible for you to implement a mask-strength parameter into CRT Super XBR? I was tinkering around with it but I found that I can only turn the phosphor grid on/off. I would like to be able to increase and/or decrease the strength of the phosphor grid in order to further fine-tune this shader.
I have been messing around with CRT-Easymode, and I combined it with grade.slangp in order to fine tune the colors of this shader for different regions of games. Personally I find that at lower resolutions using the mask width combined with mask staggering doesn’t look as good as say one of the Lottes shadow masks, so I just stuck with the aperture grill.
Here are some screenshots at 1440p. It looks great at 1080p as well, just a lower TVL with less apparent scanlines, which looks nice with the intense mask strength (especially at 4x integer scaling). I was trying to aim for a nice balance between smooth fonts and sprites whilst retaining sharpness and clarity without looking excessively blurry.
Settings are below. Grade is tweaked for NTSC-J content (feel free to adjust as necessary).

Hey, @hunterk @guest.r or if anyone else can help. I made a custom GDV-Kurozumi preset with a Stock pass set to -
scale_type_x0 = "absolute"
scale_x0 = "320"
scale_type_y0 = "absolute"
scale_y0 = "240"
for PSX games so as not to trigger interlacing in games. But the Width is not scaling properly for some reason!
Default GDV-Kurozumi (Beetle PSX HW 4x res downscaled to native) :

You can try with source scaling options too. For example:
scale_type_x0 = "source"
scale_x0 = "0.25"
for 4x internal resolution, or at least 0.5.

Thank you! That worked. (Also, is there any way to get downsampling to native res in other cores like Beetle PSX HW does? Like some RA setting or shader?)

In Flycast you can chose the internal resolution, too.

You can try the core resolution sampling multiple in the Mega Bezel, it only changes the sampling, it does not actually downsample like the pass @guest.r guest shows, but in terms of getting the correct “resolution” interpreted it does that

Not internal res. What I want is an option that downscales the upscaled internal res back to the native res of system. For example - Beetle PSX HW settings “Internal Res = 4x” with “Downscale to Native = True”
He wants to super sample it kinda sounds like?

Hey, looking at these screenshots, I see that the RGB triads are instead showing as two pixels of magenta and greenish-yellow. Is this by design, or is it part of just how these images were downscaled?
No idea. I can’t even remember which mask I used when i took those shots. And probably they’re downscaled.
