You can't get 1080 on a 1680x1050 display. Try a 720p setting.
"Other 1080p-compatible LCDs, on the other hand, have lower than 1920
I am having issues connecting my ps3 to my new monitor. Its an Acer x203w HDCP compliant with 1680x1050 resolution. I am connected through HDMI with a HDMI-->DVI-D adapter. My playstation shows up on the monitor but the resolution forces a good portion of the right hand side of the menus to be off the screen...I have been unable to make it shrink down to fit on the screen with all contents showing. This is the same for the menu, games, and blu-ray. Any help would be appreciated.
