I have celeron 800 MHz with 815E Motherboard built-in display card. I have purchased RIVA TNT2/TNT2 PRO model 64 agp card(32 MB) with TV-out facility to watch movies on TV. I am unable to configure for TV-out. I tried to configure TNT card properties device selection where only one analog monitor is activated out of three (others are digtal flat panel and TV). so i can not choose that option of TV-OUT. Could someone guide me for configuration.
