Ok. I'll check that. I have made some progress, though.
I tried simply adding new modes to the LCD pandaland MDF, scaling the
pixelrate down by various amounts. And leaving all the front/back porch
values alone. I found that 55Hz still gave 'red dots'. But 50Hz seems to
work fine, so I'm currently using that as the default.
48Hz just about worked. Gives a good image, but the screen vanished every
now and then for a few seconds. I think that 48Hz is a tad too low for the
monitor. Lower frame rates give a blank screen and monitor error message
about the signal being out-of-range. So for now I'll stick with my bodged
50Hz HD mode. Looks OK.
Overall, the behaviour seems to be that the monitor is quite picky. I find
this curious for a digital input device. Should either lock on and work or
refuse with an 'out-of-range' type error.

OK. I'll use that for a while with the fan connected to get a feeling for
the typical temperatures with the fan. Then see how much it may alter when
the fan is disconnected. The way our weather is these days I probably won't
have to worry much about a 'hot summer'. For that I'd probably have to move
to Australia! :-)
I have a couple of articles to write, so my next step is to transfer my
commonly-used fonts and begin using TW/ArtWorks/Tau/etc in ernest to seen
if anything objects. I'm also trying out my favourite general editor -
DeskEdit4 - which I hope will be OK. Zap and StrongEd have always been too
fancy for me...
Cheers,
Jim
