Assuming that the cards TV out driver will even bother looking at that value.. The card probably totally ignores the refresh rate for TV out. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 9A8C 569F 685A D928 5140 AE4B 319B 41F4 5D17 FDD5 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message

A standard NTSC TV set uses 60Hz vertical and 15.750kHz horizontal with 2:1 interlace (50Hz and 15.625KHz for PAL). Trying to run an ordinary TV at 30-50kHz horizontal stands a high risk of destroying the horizontal output transformer and associated components.

Re: nvidia tv-out
Im using a composite cable (not s-video) and an adapter to plug it to scart. It was actually plugged into a VCR, but i got the same problems when connecting it directly to the TV. I guess the horz sync freq's are wrong, but "30-50", (from the nvidia docs) is about the only thing that works even a little. What freq's work for you? Thanks for your help! // Martin Gumucio On 22 Nov 2002 09:20:23 +1030 "Daniel O'Connor" <[EMAIL PROTECTED]> wrote: > On Fri, 2002-11-22 at 02:16, Martin Gumucio wrote: > > I have almost been successful at getting the tv-out from my nvidia card to work. >The picture is there but it skips around horisontally.
