I added the custom resolution of 2560x[B]1440[/B] @ 55Hz CVT-RB timing over regular HDMI and it worked with my QHD desktop monitor. \n\nBut it seems I cannot add 2560x[B]1600[/B] as a custom resolution in WinXP. I did that in [B]Win7[/B] and[B] it worked fine.[/B] No matter how much I lowered the refresh rate, the Intel GPU app in XP keeps saying bandwidth exceeded. Is 2560x[B]1440[/B] the max I can get in Windows XP?
