Hi, Yesterday I installed a PNY 9400 gt to my computer, It came with the dvi to hdmi adapter so I tried to use it, I connected the hdmi cable to my Samsung 37 LCD TV that I bought 2 years ago. And when I turned on the computer it was receiving signal, just before Windows logon screen, it stopped working. Can anybody help me and tell me how can I switch my graphics card input, I'm still using my tv as a monitor but with the vga cable plugged to it.
