Nanao MS-2932-S at 800x600?

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.
