Hello! I bought a viewsonic VX2258wm touch screen monitor and it worked quite good but now I am having problems with a touch function.
Everything works fine but after aprox 20 mins touch screen shuts down and is not responding! I tried everything I even reinstalled windows 7 and checked every other setting but I cant find a solution. After I unplug usb connector and plug it back in it works for another 20 minutes! Any ideas what could be the problem?
