I currently have a Dell Optiplex 980 running Windows 10. I was given a new (old) monitor...a Dell P2212Hb 22"...and the best resolution for it is 1920x1080. But the current video card (ATI Radeon HD 3450) won't support that resolution. I have an EVGA HD Radeon 6850, and I wondered if it would support that resolution. If so, I'll swap them out.
