We are going to each of our newly installed panels (ActivConnect OPS-g AP6-75A-4K ActivPanel 75″ 4K) to ensure they are functioning correctly, and have run in to an issue. We changed the resolution of the boards to 1080p 60Hz on many of the boards because it seemed to help with another issue we were seeing. However, on one board, we believe we may have chosen 1080I 50Hz instead of 1080P 60Hz, and immediately after, we got the “No Signal” message. We have rebooted the board and the OPS unit, but nothing has worked. Anyone have any ideas how to fix this?
Thanks for your response Adam K. We tried the steps, but were not successful. I remember about a year ago doing a factory reset on one of our boards, and it wouldn’t work with a 32 GB USB. We had to use a 16 or 8 GB. Trying that now. Will let you know.
