Hi,

TV has both S-Video and Composite plugs.

In this topic https://www.videohelp.com/forum/archive/notebook-s-video-output-and-rca-tv-t340968.html
people told that GMA 950 not support Composite out even with S-video <--> Composite cable,
but I use this TV with S-video <--> Composite cable and it works.

The problem is wen I use S-Video <--> S-Video cable, laptop identify TV connected(in use), but there is no picture on TV
Was checking in all menus in laptop and TV( changing NTFS/PAL and all other setnigst i can) and can't understand why there is not picture with S-Video <--> S-Video cable but there is picture wen use
S-Video <--> Composite cable.

There are often limitation on the desktop resolution if you want to use s-video or composite out. Try setting the desktop resolution to 1024x768 or less and see if that helps.

Also determine whether or not the port on the laptop is a 7 pin connector or a 4 pin connector. The 4 pin connector is common on dvd players and the like. The 7 pin is more common for computer outputs. You should be able to get a 7 pin at your local electronic store should you need one.

There is two available resolutions for TV-out 1024x768 and 800x600 both don't work, S-Video port on the laptop and TV are 4 pin

I think there is two reason for the problem, the laptop send a analog signal that TV cant recognize or TV S-Video don't work.

Whatever, I will tray S-Video signal form different source ... to see were is the problem in laptop or in TV

If you used an s-video to composite adapter and got a picture from that the s-video port on the laptop is working. Try using that cable/adapter again. Once you get a picture on the TV (don't turn the computer off or reboot, leave Windows running) swap the cable/adapter with the s-video cable. Still working?

I already do this, don't work.
The cable or the TV, that left.

Thank you!
