Try unplugging the Monitor cord and just have the VGA cord plugged in and restart.

And make sure the TV is on AUX channel

well i will try that in morn,but sould it not work without all that bother..???

I used to run a S-cable to my TV for movies and such and I'd have to shutdown, unplug the monitor cord, plug the S-cable in and turn it back on. It always worked for me.

holy f...,that would be a nightmare for me as pc is built in....not so easy to dis-connect..

what about the code ten error???

Are you using one of those computers with the monitor and tower built together? I'm sorry, I have absolutely no experience on those machines...Maybe just restarting would work...

if i just upgrade my GeForce FX 5200 to the latest driver, will it be beneficial to my pc overall?? and will it work?

right lads,seems my graphics card is not strong enough to run two screens of high resolution at a time/or the spare monitor port,vga, is not working, as i have swapped the cables around, and large screen is perfect but 17in is off.. as i don't want to buy a new graphics card just for this, i am getting a vga splitter.. thanks guys..
