In my other post, I describe the various builds I've tried in an attempt to resolve this issue.
Integrated graphics with a Core i7 processor (connecting DVI to the MB) doesn't work for me.
A Gigabyte ATI Radeon HD 4550 card from my older computer that worked fine doesn't communicate with the monitor on my new PC build.
Microsoft tells me it's a hardware compatibility issue.
NEC tells me it's a driver issue.
I'm waiting for Intel to provide support. I'm waiting for Gigabyte to provide support.
