This is sort of a bug but may be considered a feature request.
When running 480i output at line4x mode with scanlines on and in manual mode, horizontal should result in every other output line being darkened. Instead, it seems to result in the same thing as alternating. I’d like the output result to look similar to how scanlines on 480p looks when run at line2x with every other output 960p line darkened.
This doesn’t affect line2x so I think it’s just a bug.
I wanted to reply and revive this thread. I would really like for horizontal scanlines to work correctly in 480i 4x mode. They should work the same way as 480p 2x to emulate scanlines of a high-res VGA Monitor. Right now, as other’s have pointed out… ‘horizontal’ is only producing ‘alternating’ scanlines in 480i 4x mode. Thanks!
