success. Now I'm only using an AGA 1200 but I'm SURE I've heard of people
connecting these to PC monitors before. I know I can't use 15kHz modes or
anything but that's not a problem - I just want to see Workbench on a PC
monitor because temporarily I don't have access to my usual Microvitec
multiscan (I'm typing this on an awful old Acorn 15kHz monitor). I've
tried in the past with a different monitor and had no success but it's
really important now.
I've tried DBLPAL, DBLNTSC, Super72, Multiscan, Euro36 and a variety of
others but no success. I've also tried with and without VGAOnly.
Perhaps I can fiddle with the tooltypes of DBPAL or something to get it to
work? Any help would be MUCH appreciated before I drive myself to despair
trying to work with a 640x256 resolution!
Haven't had a chance to fiddle with MonEd yet because (as a side issue) I
can't get Genesis to connect to BTInternet so if anyone has managed that
I'd be interested too! (it doesn't seem to want to CHAP authenticate
itself)

Well, it would seem so on the two monitors I've tried...VGAOnly puts the
frequency of DBL[PAL|NTSC] up to 31kHz but no luck (well, the Dell branded
17" here briefly synced on DBLPAL, albeit with the display aligned totally
wrong horizontally, but after a few seconds it lost sync.
Will adjusting the tooltypes of the drivers affect the relevant frequency
(coming from someone who doesn't *really* understand what all those things
are about)? And if so how does one adjust them to up the scan rate?
And finally what is the usual frequency used by a PC output?

Well, I have worked it out! I am using the VGA monitor now...
It seems that it wasn't actually the scan rate that was the problem, this
monitor seems to be able to go down to <28kHz.
For anyone who wants to know, what I did was do a lot of trial and error
with MonEd. I ran WB on a 15kHz monitor, in PAL mode then ran an
application (e.g. AmIRC) which was set to use DBLPAL. This sends the
screen wild (obviously) so you switch back to WB. Now run MonEd, click
"jump" which puts it onto the AmIRC screen. Switch back to WB again and
drag the screen down so you can see the AmIRC screen behind. Play with
the MonEd settings, then switch to the MonEd screen and plug in the PC
monitor! Long winded but eventually I found some settings that worked.
For future reference, it seemed to be the VSSTOP parameter which needed
fiddling with most urgently.

Hello Tim,
Try using DblNTSC as opposed to DblPAL. It uses a SLIGHTLY
higher refresh rate. Productivity also will nearly always work.
You can play with MonEd to get DblPAL to function properly.
Well, unless you're happy with your normal VGA monitor now. :)
