Im using a 27' samsung lcd hdtv as a primary monitor right now with a 19' secondary. It has a dvi input but i wanted to connect it via HDTV cables. I have the necissary break out cable, RGB cable that came with the video card. I hooked it up and everthing but the TV says that it has no signal. I attached it thru catalyst and windows, but it has no signal. The specs are Abit KN8 mobo X2 3800+ 2048Mb Xpert RAM HIS X800GT Samsung Syncmaster(19') samsung HDTV (27') Its an amazing display, i dont know how im gonna get back to using my regular monitor. Another problem i have is that it wont go past 1024X768 in HF2. i guess its just cuz the connection, im sure if it was hooked up by HDTV cables then it would work.
