I am using Windows 7 on a home built computer with an ATI graphics card. I have my computer connected to my HD TV with a 50 foot HDMI cable. My audio is fine, but my video is watchable, but poor quality. I get little blue speckles that come and go, especially in dark areas of the picture. Sometimes there are very few blue specks, but sometimes it is pretty bad. I suspect the poor quality picture is because of the long HDMI cable, but I'm not sure. I don't want to invest in a HDMI amplifier if I don't have to. Any suggestions for me to improve my picture?

Supposedly simple test.
Move the PC closer to the HDTV and use a shorter HDMI cable. Do you still have the same "specks"?
Good idea, I can't move my computer. I will try moving my TV, but that is easier said than done. It is a very large TV.
