Important note: This is a touch-screen model, requiring a USB cable (USB B connector); however, to date, I've not been able to get the touch screen to function. The monitor itself works fine, but I do not guarantee the touch function.
Speakers require a 3.5mm analog input. Stand is not included but it uses a standard 100mm VESA mount. A standard VESA stand or wall-mount bracket would work. Cables will not be included unless asked for (no extra charge) - these would include power and DVI-D or VGA (D-Sub).
