A screen to rule them all!

Very good product that comes with all the connections (4 VGA / USB cable + 4 audio / mic cable) to connect four positions on a single screen in the audio manager + microphone.
Clever VGA cable that also incorporates the USB cable.
I use Windows 7 and Windows XP that recognize no drivers to install.
I see no degradation in video quality on my LCD monitor 1920x10810 60hz full HD via VGA.
Contrary to what was stated in a comment, the passage Win7 to XP or conversely requires no monitor setting. This is totally transparent.
My mouse intellimouse 4 buttons + roulette is well recognized management.
It restores the status of your keyboard (eg keypad) to each switch.
Great product that I recommend.
