Scanline crawl on tv but not on lcd


im using crt-mattias.slangp, and it has a scanline crawl effect that doesnt appear on my lcd, but appears on my tv.

anyone know why is that?


Not sure what you mean by crawl. But it could be same issue I had on my lcd tv. It wanted to autostretch no matter what I did resulting in uneven lines. I could only find one solution and that was one particular resolution that filled the vertical space exactly, wich made the tv to not stretch the image. It’s maybe not the same issue, but could be.

after some careful inspection i realized it appears also on lcd, but very difficult to see it due to the lcd properties, crawl is an effect of the shader, in which scanlines move, and cause some artifacts like ripples
