I'm having some problems with my ASUS Radeon HD 5770 video card and Samsung Syncmaster P2370 monitor:
- I found if I directly connect my monitor to the DVI port on the card, there is no display. I have to use an adapter to connect to the VGA port or HDMI port, then the monitor works.
- I changed to another video card (GTX 460) and connected to its DVI port from the monitor; it works just fine.
- I switched back to the HD 5700, and using another ViewSonic monitor, connected it to the card's DVI port and it works fine too.
I don't know what the problem is. It seems the card works fine with other monitors and the monitor works fine as well with other cards.
Is there any way to fix it?
