RE: Frambeffer to TV troubles

That is correct... Had it worked immediately, I'd not have bothered to
post ;-)

With the adjusted pixel clock, I am able to select between 640x480x16bpp
and 800x600x16bpp (perhaps others) using the vesa modes, without
trouble.  The weirdest thing was that fbset would change the patterns on
the TV, so I thought it was working. It looks like everything was
changing except the pixel clock...

So if you pass these values using fbset, it doesn't work?

Strange...
