Nanao MS-2932-S at 800x600?
grantspain:
i just fix them and i only test them on 640 x 480

You won't quite hit 600@50p within the 31kHz limit. You can get to about 576@50p.
(Scan Rate) = (total horizontal lines each frame) x (Frames per second)
31kHz = (480visible + 45blanking) x 60fps
31kHz = (576 + ~50) x 50fps.
Be aware that if you try this sort of thing with certain MS8 monitors it will appear to work fine and give a stable picture, but cook the sync circuitry in a few weeks. Those monitors have a sweet spot and don't like operating outside it. I've only heard this about the MS8's though, other models and monitors should be perfectly fine, including your MS9, but i take no responsibility for what happens.
Another option might be on old TV with RGB hacked into it. TV's are surprisingly adaptable and will look pretty good at 800x600@50i (interlaced) if their sync range stretches quite that high. I've found a few consumer sets that do, so you might get lucky.

Maybe this modelines will work:
Modeline "800x600_50.00" 31.15 800 824 904 1008 600 601 604 618 -HSync +Vsync
Modeline "800x600x50.72" 31.752000 800 824 904 1008 600 604 608 621 -HSync +VSync
Modeline "800x600x50.00" 31.298400 800 824 904 1008 600 604 608 621 -HSync +VSync

That's for you to tell us :)
I have no direct experience with the MS9's, or indeed with any Nanao not actually designed by Kaga Denshi in the late 70's :)

Hi!
Ok I tested 800x600@50 and worked perfectly, Tried adding more horizontal resolution (line 1066x600@50) and worked too.
The image is very sharp at 50 Hz.
