Would appreciate any insight or advice. Have a Philips 21:9 ultrawide monitor that I've been using with my p1801 for about 3 years now. Always had a problem re-establishing picture when going into sleep mode. Early December I go to my PC and the monitor won't wake at all. So I try it with other computers, get mixed results and use my extended warranty on the monitor. They tested it and said it was working fine.

I just set the monitor back up with the P1801. In NVidia's control panel it can detect the monitor but there is no picture. Monitor just says no input signal. Is there some setting or something on the p1801 that might be messing up the hdmi handshake?
