I went and got a new cable box that has an HDMI output. Now, the only problem is the cable company (Cox) said they don't support HDMI, because the new Motorola box has a software problem, and only works properly on some sets. The problem is (if you have it), that the cable box needs to be re-booted everytime you shut the tv off, and then turn it back on. They said to make it work, you have to unplug the box and replug the box each time you turn the tv on.
I'll have to get an HDMI cable, and see if it works for me. I tried to buy one locally, but every store near me only sells Monster Cable or some other high end brand that is $100.+. I'll have to order one on line through a link I was sent.
