OS4.0 and AGA video mode @31.5 kHz...

[alexh]

Yes. It will be slow though and as you already know WHDload (or any software which controls screen mode) wont work.

I have to disagree. All monitors including LCD's HAVE to support 31KHz for low resolutions to meet the VGA VESA standards. I've never come across one that doesn't.

The vast majority don't do 50Hz vertical sync (DBLPAL), perhaps you are getting confused?

Most LCD monitors cannot do 50Hz but just use DBLNTSC which is 60Hz

Matt, I agree that it's not a good long term solution, but I dont agree with your reasoning.

Almost nothing (except workbench et al) supports ANY DBL mode be it DBLNTSC or DBLPAL. Game compatibility in DBLNTSC over DBLPAL is the least of your worries ;-)

There are perhaps 5-10 games (that I know of) which support mode promotion (i.e. run in a DBL mode) for 99% of games they wont run in anything other than regular PAL/NTSC.

[EDIT]I've just read about a tool called ModePro which could help promote more software to DBL modes that I was aware of.

But you are right, I always encourage people to seek out LCDTV's or buy a scandoubler rather than mess about with DBL screen modes.

AFAIK it doesn't but like yourself I am not 100% sure. (Especially having discovered that modepro application)

I've had a scandoubler in one form or another for a long time and it is just ingrained into me from talking to others that it doesn't work.

I would imagine too many games/applications reset the contents of the registers which control those settings.

Otherwise there wouldn't be such demand for scandoublers?
