[quote]What kind of TV is it?
Standard 1080p LG TV.
When I setup mine, I simply had the three monitors I wanted with surround plugged in, configured surround, turned it off and then plugged in the fourth monitor and enabled it after boot.
I just did the above, but when I re enable Surround it wants to use the monitor/tv that is connected to the HDMI port as one of the three... With" turned it off" you mean in control panel right?
Turn computer off, plug in only the 3 monitors you want for surround, turn on PC and enable/configure surround. Turn PC off, plug in fourth monitor, turn back on. Surround should still be configured and enabled at this point. Then you just go into NV control panel and enable the display under set up multiple displays.
At least, that is how it worked for me. I already had the surround setup with the three other monitors, and later added the accessory display to the mix without disabling the existing surround.
