I just fired up Term 4.7 today and whoa, the 2032MW really doesn't like it in the current screen mode (PAL Interlaced SCART). The sync is completely messed up - The screen is jumping around all over the place and seems to have a tendency to sit half-way across the screen, with the frame blank in the middle. As for composite it’s stable, but the frame blank is still in the middle of the screen and it’s accompanied by a rainbow pattern at the edges of the frame blank and flashing diagonal lines. The RF mode may as well as be white noise.

Might just be Term, but Term worked fine on the 15" PC CRT I used to use (Multiscan Productivity, 640 x ? screen size)

If someone else could try Term out (From Aminet) on a 2032MW I’d be interested to hear what it looks like.

Yup ;-) Actually I've barely used it so far.

I finally did a test with my 2032mw to see the SCART input from my Amiga and I must agree with arkpandora that it's bad! While VGA works like a charm and non-native resolution adaptation is very good, SCART input is not.

I'm going to try a NeoBitz S-Video module with my 4000 if I can get one!

Correct me if I’m wrong here, but one of the biggest problems seems to be (From what I can see) is the in-built interpolation for movement of an image. If it were turned off, the display would be reasonable, but since it cannot be turned off by the user it results in any moving object on a uniform background taking on a ghostly, shimmering appearance...

That and the slightly dark picture; even on full brightness the white isn't quite white.

@Flashlab

Thank you for your evidence.

non-native resolution adaptation is very good


As I said earlier, the monitor is unable to recognize the resolution of a Philips CDI console for example : it scales it down.



@Hodgkinson

I'm not a computer specialist, but as discussed before it seems to me that it is not interpolation which is at fault, but the scan-doubler, as animation in non-native VGA modes is normal.

... among other problems, which destroy 2D animation.  And colours are bad as well.  So to my knowledge this monitor's video inputs are only usable for cheap television or movies, and maybe 3D games if the console doesn't use 2D animation at all (as for me even the Amiga mouse pointer is unbearable on this monitor).

With non-native resolution adaption I mean resolutions like 640x480, 800x600 etc. are nicely displayed without blocky and unevenly spread pixels like you see on some other LCD screens.

Sorry, I didn't realize you were only considering VGA screen modes : then I agree.
