but surely there's more? I already applied those and it's not really satisfactory (blacks aren't very black and colour seems off). I should probably mention that the exact model I have is 22EA63V-P, but I didn't think it would make a difference to the display quality. If the implementation was different, you'd think they'd use a different model number.
