Reply To: Slide image left and right..

Aha I see. You could try to move that edge by increasing H.Active. Although I notice now, that doesn’t actually work in Lx3 mode on my screen, although it does in Lx5. I guess that’s due to the differences that are going on “under the hood”, to achieve valid output formats.

The only other option I can think of is that you have added horizontal mask, which then would cut the image too far in.
