Hey guys, I'm running GTX 460 1GB's in SLI and I've been using DVI and HDMI to get a dual screen setup with my old Viewsonic VX2025WM (DVI) and my Toshiba 32" LCD TV (HDMI). Recently I bought a new Dell U2412M monitor and a DisplayPort cable to go alongside it. When I plug my DP cable into one of the cards, I notice that I get no signal from my HDMI cable no matter which card I plug the HDMI cable into. Is there a reason for this? I've never used a DP cable before so I'm confused as to why this is happening. The main reason I want the HDMI on to the TV is because I have everything in the bedroom so it's nice to move watching movies with the wife on the bigger TV without the need for headphones. Do I have to choose either DP or HDMI or something? =\
