I am a disabled vet and not real tech savy anymore. I am trying to get my PC to work with my TV. but need some help getting it all to work together! I have a TV that has lot of diffrent inputs to include a monitor port to hook up PC. I have a Direct Tv tuner box. I have a PC with a nice video card and a TV tunner card. On board sound. I currently have the direct tv box hooked to the tuner card with S-video cable. I currently have the PC hooked to the TV via a monitor cable with an adapter to hook to the square hole ports on the video card to the TV monitor port. I can see the PC on the tv and can use it like a PC, but when I run the TV tuner program I dont seem to get a signal from the direct box. Am I hooking the cables up wrong or something? I have no sound I assume I will need to get sound cables from the pc to the tv? If anyone can help me sort this, so I can watch the ball game while I play poker..I would really appreciate the help!
