Thanks, Chris. I've tried that and still not working. It will say there is no HDMI cable. Does it matter what type of HDMI cable I have? (Expensive vs cheap one, etc?). I used the same cable to hook my PS3 up on the old U2711 with no problem though
Have also tried a few other recommendations to set the resolution lower to 720p on another TV, and to reset the PS3 video input by holding+pressing the power button
Let me know if there are other things that I can try on? Cheers!
