Cytat: Q: How can I get the SiS TV-OUT function enable?
A: SiS TV-out function supports both NTSC and PAL system. You have to select the one which matches your TV system. In general, it is controlled by a jumper on the motherboard or the graphics card. We suggest you to check your user manual out for the setting. The following is the instruction to connect to TV:
1). Connect with TV by either a S connector or an AV connector.
2). Boot the Win95/98/ME system up then you will find the tap SiS TV-OUT under Display Properties. Choose the display mode to VGA+TV or TV Only then you can get the TV-OUT.
3). If using Windwos 2000, there isn't a tap under Display Properties, Please set your display mode on 640*480 60Hz for NTSC, or 640*480/800*600 50Hz for PAL to get TV-OUT. Don't set your display mode to other mode for TV-OUT, most TV set can't support other display modes except above mode.
