Reply To: How to get scanlines and vastly improve picture quality: the best method

[patl]

Check your Retrench render resolution.
When you load a rom press “x”, select point “8”
(Select Retroarch render res for xxx)
in the menu select point 5
(Use video Output resolution)

And be ensure that your display is a 1080p display.
Otherwise scanline overlay image of patrickm will be downscaled, the scaliness itself blurred and only darken the whole image.
