I've got a client at a golf course with software that captures videos from two cameras. One video is from down the line and the other is from straight on. They have two physical displays, 1 computer monitor connected via VGA and a big screen TV connected via HDMI (DVI to HDMI converter).
Recently, the video card went out on this computer, so I replaced it. Everything is working except for two instances.
If the user selects a 'split screen' display (showing the input from each camera side-by-side), the TV display goes black. When you go back to another display that works, the TV briefly displays the split screen as it should have, but then switches to the new type of display selected.
If the user selects a previously recorded video and plays it back full speed, again the TV display goes black. However, if you pause the video it will display fine on the TV. You can also play it in slow motion and it will display. Only full speed playback causes the issue.
I'm trying to troubleshoot this to the best of my ability before doing anything else. I've considered buying a better video card to see if this is the problem, but I don't want to do that until I've eliminated any other possible issues.
Thanks in advance, Jeff
