I am incredibly disappointed in this Aten. I have long possessed an Aten CS 1732 but I wanted to change because it is a model only VGA and the image is slightly blurry on the big screen. So I bought this HDMI switch. Very well finished but the problem is that after one hour of operation (not to switch screens), the housing and the screen must be heated (a IIiyama 26 ') flashes, séteindre, turn back, In plugging my HDMI cable live, everything returns to normal. I am running Windows 8.1, Asus Z87-Plus, with integrated Intel i74770 video output. The switch firmware has been updated before use. Anyway, I'll see how to get a refund received this yesterday. Avoid
