The Highway Model 100 converter does a FAR better job on the desktop.

Yes. Reposting some of my old photos, you can see the differences:

http://www.cimmeri.com/js/download/

RGB1-7.JPG = IIGS ->  Keene Aptus ->  Samsung 192MP
                    = RGB ->  RGB/YUV ->  15khz YPbPr in
                    = A-A-(A-D upsampled to LCD)

    Problems seen on desktop are due to the 192's high bandwidth
Component input, and its sampling rate creating aliasing effects.

    The Samsung 910MP with SCART does NOT have this problem
    as the SCART input is bandwidth limited.


In case anyone is interested in seeing pictures of the Apple IIGS desktop on a Samsung SyncMaster 940MW wide screen LCD monitor/TV using just the IIGS to SCART cable (no converter box) I have included the link I posted some time ago:

I have added another picture of the finder desktop with 4:3 ratio and periwinkle blue background for comparison with others posted in this thread.

Now *that's* lovely!  ;-)
