im probably just bein really dumb but i cant seem to figure it out.
my problem is that my image is offset to the right. though it actually looks more like its squished to the right.
meaning the right side edge is properly aligned with the screen, but the left side has a gap.
that should mean i have to adjust the horizontal backporch, right? tried that, nothing changes. yes, i clicked restart.
also, those modelines listed in the pastebin, why are they 2560x480 and 3840x480? and how do i add all those values anyways? they arent labeled where they go.
