Now I have an order of these parts here - and I'm thrilled! Did it without a driver CD connected to my private Win7 computer, hang on the already two monitors. Was immediately recognized and installed monitor off running! A quick set the display position with Windows resources board and already my desktop extends across three screens. GREAT! Had I discovered this thing earlier, I would have saved myself a lot Nachdenkerei and long search in the I-Net. For the planned bar display I will equip a small nettop PC with Win7 or XP and then conjure up with three of these adapters a giant desktop. Then on each monitor IrfanView in fullscreen mode.
A small drawback: The supplied adapter is white and not black as in the picture. But bothers me less, because the part is anyway disappear behind the bar cabinet.
