I have 2 of these displays for sale. They work great with any Mac with DVI or VGA video ports. I am asking $100.00 each (original cost just over $650.00 each). They were used side-by-side on my Mac Pro. The original User Manuals are included, these are 4 x 3 display ratio. I can email a PDF of the manual to any interested party. Send request to Brian dot Stone at Mail dot com. Thanks for your consideration.
