My tv is hd plasma 1080P. Trying to connect my sony laptop thru VGA. No connection, but when I use my other hp laptop to tv with the same wire. It show connection. Some thing wrong with sony laptop's VGA outlet ??????
It sad no one answered my problem. But I do have my own findings. It is sony laptop. I talk to them. Sony told me that there are some plasma tv are not fully compatible with sony laptop. They helped me to download some software. Now it is working great.
