I have tried A1200, A600, A500 and A1000 with the VGA adapter.
This is to confirm that my DELL ST2410 (it is a full-HD with HDMI) is able to show the 15 hz screen (including KS screen)
For some unknown reason only the A1000 doesn't work..
I must say that the wide screen is a bit too large for my taste, so I prefer to normally link them to a smaller 17" through the indivision.
