I recently bought a Acer V243HD and i'm planning to use it both as monitor and TV.
I use a Asus My Cinema-P7131 tv card gekocht, PowerCinema 5 was provided with it but I had problems with sound it contained noise.
So I siwtched to Windows Media Center 11 and have excellent sound though tv is shown in 4:3 instead of 16:9 no mather what settings and resolutions I choose.
This is a screenshot of what I mean, you can see that the middle part is used (upper and lower parts aswell as it is abit grey)
