I have a similar problem. The big TV set is too far away and I would haven to enlarge the hole inn the wall for a VGA cable.
The viable alternative is to get an MP4 player expressly made for watching on TV, It works real good on AVI and a few other formats. I can stick a USB stick in it and watch on my TV. It even has the R-G-B things that my TV likes. Audion is on a perpetrate cable.
Here is a picture of the thing I am holding reside the TV set. Some of the cables are for my DVD, but the MP4 has its own cables and power supply. The quality of the MP4 player is close to the DVD. Sometimes equal, ,depending anywhere I got the AVI movies.
The cost of this thing is about like buying two good cables. But it has is own short cables. And I don't have to tie up my laptop to watch a movie. Just put the movies on a USB stick. If AVI or MP4, no conversion needed.
