This is a bit of a hack, but it does work on some TV's:

 The SCART input on televisions does have a number of pins I think are marked
 TTL RGB in. If you connect the ANALOGUE RGB out from your computer into
 the TTL RGB in, and any other SYNC and relevant pins, a small number of
 Televisions will accept this signal if you put it into teletext mode.
 I know a few Ferguson TV's which accept this, and perhaps a few others do
 too. I don't know the actual pin-out required, but I am sure you will be able
 to look it up somewhere.
