Maybe your Stroboscope LED's are gone down in intensity (or one of the
three ?) ??? The intensity of those is very important for a "reasonable
contrast", but I agree on the S/N, I was quite dissappointed getting the
Monitor on a FACStar Plus just last month :( !!! For all the money the
picture should be better !

Have fun,

Matthias
