Fix Scanline for custom resolutions?

RetroArch Additions Shaders
#1

Heyho :slight_smile:

I made an Tv Overlay and when i scale the Picture in custom mode to fit the overlay, the scannlines are not right :confused:

Is there a way that scannlines from shaders does work with all custom resolutions ?

Scanlines can’t be even on non integer resolutions, it’s impossible If you are making just an overlay you can just include the scanlines overlay for your resolution

by using only ctr-hyllian alone … the scanlines working correctly. but the Combo with xbr makes the space between the scanlines to big.

this one is with the wrong scannline:

this is correct wirh only ctr-hyllian:

without xbr it works .

if using xbr and crt hyllian togehter… there is a Problem with anything .

Which one is done first? XBR or hyllian? You’re changing the frambuffer size, if you do XBR first for instance I would expect scanlines to become very thin, I guess you’re doing scanlines first then scaling. If you just want black lines evenly spaced 1 pixel apart that work for any framebuffer size the best thing you can do is add them to your overlay
