Summary: Works flawlessly, supports my highest resolution. Wished it were USB instead of P/S2.
Pros: Flawless switching between 4 dual monitor computers. Included cables are DVI-I, so I was able to use DVI-to-VGA adapters for my 2nd monitor which is VGA. Hotkey switching. Supports 1920x1200 resolution.
Cons: Not the fault of this unit, but wished it were USB instead of PS/2. However, dual monitor USB KVMs cost mega $$$ got this one cheap though
