Problem with TV-out on my stb 4400 TNT 16 mb. Hello. I've recently bought a stb velocity riva tnt

Question

Hello. I've recently bought a stb velocity riva tnt and today I tried for the first time to connect my pc to the tv. The problem is that I experience a lot of black space around the tv-screen when I choose tv-out. My system is: amd 350mhz w/3dnow stb riva tnt 16 w/tv-out microstar 5169 mobo(ali v chipset) I have installed the 2.08 detonator drivers, because I couldn't play openGL games at all with the stb drivers. I also have the latest bios for my tnt. Can anyone tell me how to strech out the the display so I decrease the black frame ? /Marcus
