you can have sound. the dvi-hdmi adapter that came with your graphics card CAN handle audio with video. but you need to use that adapter and hdmi cable. make sure that in audio settings, you set it to use the graphics card audio and not your mobo. i have diamon hd 3870 with 512mb ddr4 ram and it works flawlessly with 42" 720P lcd phillips tv.
But does it split the sound or will i listen to the same thing i listen to in my speakers connected to my onboard soundcard
? If someone is watching a movie on the desktop monitor will i be able to play a game on my lcd-tv and only hear the in-game sound and not the movie sound?
