I’ve searched all around and can’t find a scanlines only shader. I am running on a CRT Pscan monitor and I would only like to add scanlines. Is this possible?
Someone else suggested CRT-Geom and I tried that and turning off the shaping, but it seemed to mess with the image too.
There’s a shaders\misc\scanlines shader.
You can also check out the scanline overlays.
your crt monitor can actually produce real scanlines, you need to run windows vista/7/8/8.1/10 then create custom monitor.inf or add resolution using CRU (Custom Resolution Utility), then create 320x240@120hz resolution for 240p games since 31 khz monitor cant display 320x240@60hz, the key is same resolution size with double refresh rate, you can do the same for other resolution like 512x240@120hz for games like crash bandicoot and 400x254@106hz for mortal kombat arcade and 320x200@140hz for dosbox games(DOOM & Duke Nukem 3D), but for snes and nes resolution you have to use 256x224@150hz because 31khz cant display 256x224@120hz because its horizontal clock is under 31khz. i never use this technique with retroarch because i already switch to lcd and never know if retroarch is capable of auto switch resolution like mame and dosbox. if only there’s a brand new flat, thin, lightweight crt monitor i never would have switch to lcd. and also check this article from filthypants:
