I finished building a PC last week and tested it out on a monitor and it works fine. Now I'm trying to use a different monitor and I get errors along the lines of 'unable to connect' etc. I have everything plugged in and tried everything. Anyone know a fix? Thanks.
EDIT: The graphics card is a PNY GTX 560
make sure your not using the onboard video ports. if your not see if the onboard is the main video now and check that your video card seated and has power. if the onboard does not work open the case and see if ram and everything still connected.
