Ive recently switched to an OSSC and using it for a while but theres been a problem since day one
When outputting from my OSSC, with my monitors (including the new one I just got as well) it just refreshes every 15-30 mins, going black for about 3 seconds and showing the hdmi output label on the monitor.
Whilst however it doesn’t do this at all on my XCapture-1
I tested it separately and directly connected the OSSC to the monitor and it still has the same issue
Wii Component set to 2x
N64 RGB set to 4x (Xcapture-1 cant handle 5x)
Monitor im trying to use is a BenQ GL2450HM
Had the same issue on my Asus VE248H
Well this sounds strange. Have you made sure it’s not the HDMI cable? I.e. use the cable going to capture card to the monitor instead. I was also thinking if the input setting on the monitors is something like Auto (ie it will search for inputs), try setting it manually directly to HDMI instead (or VGA if you’re using a passive converter).
Are you sure the capture card doesn’t lose a few frames? To see if it is the OSSC losing sync press the info button and let it stay at the screen with “Vmod” on it. If the OSSC will lose sync then it will exit out to the main screen.
