I just picked up a new tablet monitor (a Yiynova MVP22U) to use as a second monitor and I'm trying to get it set up, the monitor has a built in DVI cable which I hooked up to the DVI slot on my graphics card (a Geforce GTX 550 ti). For some reason the OSD says its in VGA/Analog mode and I can't change it, switching the input to DVI causes the screen to black out and show the message 'No Signal' for a moment before going back to VGA again.
I managed to fix it once somehow by switching which of the two ports the monitor was plugged into, I loaded up the computer and it was in DVI/Digital mode and working fine for the whole time it was on, then when I turned it off and back on again later it was back to VGA mode and I haven't been able to fix again since.
It wouldn't be a big issue but in VGA mode there are very subtle horizontal lines scrolling across the screen. They don't show up during startup or in the BIOS, only when it gets to the desktop.
Does anyone have any idea of what could be causing this? I'm worried maybe my graphics card needs to be replaced but I really hope thats not the case.
EDIT: Apologies if this is in the wrong subforum, I meant to post it in the Displays subforum.
