Hi
I have both an original Microvitek branded monitor and an Amiga one. I don't have them with me now, and I haven't used them since some time (both need repairs) but as far as I remember they have the same controls (no horizontal size) and more or less, looks the same. The Amiga one has built-in stereo speakers (the other not) and a 23 pin video connector (the microvitek has a VGA connector).
I'll chek during the weekend if I remembered something wrong, and in case I'll post again.
Hope this helps
