Hello! Can’t start monitor at 1280X480 on vim3! You can correct the parameters! On edge, I started on Timings CVT, here in this calculator Video Timings Calculator. I understand that you have CVT-RB registered. Help me please.

I’m sorry. This might be a bit over my head, but I don’t know which post you’re talking about and gets a bit over my head. Can you help me out?
