Thanks for the help guys.
Here is more info: I have two HDMI ports on my TV and two HDMI wires. One HDMI wire was supplied by DirectTV when they installed and that wire is connected to my DirectTV receiver. The other HDMI wire I had to purchase myself awhile back. It is connected from my TV to my DVD/VCR Recorder so that I can record programs.
So, I took your advice here and removed one wire from my DirectTV receiver and connected it to the HDMI port on my computer just to see if it would work. Well it did work and I got the computer screen on my TV! Now I have two questions.
1. While the picture on my TV is great, there is no sound coming out of my TV, it only comes out of my computer speakers. Is that correct?
2. Can I record the shows that show up on my TV screen to a DVD or VHS?
Thanks.
