TV RGB signal output from a SVGA graphics card


Posted on Aug 5, 2012

The idea to produce a standard TV PAL signal using a SVGA graphics card was born a few years ago, where cheap graphics cards with TV output were still not available. To achieve a CCIR conform TV signal with 50 Hz vertical interlaced refresh and 15.625 kHz horizontal frequency on most SVGA cards its possible to re-program CRT timing and generate output signals outside the normal specification range.
