"Signal out of range" during POST with s-video cable connected

I have a problem on a LG1710S screen, a Abit NF7-S mobo and a
radeon9800pro... I get "signal out of range" on screen during POST if I have
my s-video cable connected at the same time... if I remove s-video, there's
no problem.

Anyone know why this is happening? It could be a gfx-card issue, but I've
never had this problem with same card on other mobos. I've also seen a guy
report the same problem with a Asus mobo and a different gfx card than
mine...

I think this has to do with your display property settings.

Having the boot screen appear on TV when the cable is connected is normal. I
can't speak to the TFT, but I know they don't have a lot of leeway on
refresh rates. It could be that the card changes the refresh rate when the
S-video is connected and the TFT is out of range until it hits Windows and
the settings in display properties kick in.

Once you're in Windows, go to display properties, settings, advanced. There
is a displays tab that lets you enable or disable the TV output and set the
clone options. Check to make sure the monitor's resolution and refresh rate
are what you want, and choose 1024x768 60hz for the TV. Apply that and see
if it helps.

(You can also use the overlays tab to select "theater mode" so movies play
full-screen on the TV even when you're watching in a window on the monitor.)

If the above doesn't help, you may be stuck unless you edit the bios of the
video card to boot DOS at a different refresh rate. There's a RadEdit
program that will let you do that.
 
When you have the S-video cable plugged in your card uses a 56Hz refresh
rate so your TV will support it. Most newer (1998+ I think) monitors cannot
support 56Hz.
