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.
any moving object on a uniform background taking on a ghostly, shimmering appearance
... 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).
