Screen 24 inches of good quality at a very affordable price. I connected to a screen Acer tower with Windows 8.1. A report that the HDMI connection did not work automatically. Jai serve me the "Menu" button to set the HDMI connection mode. This is not hard but you need to know. As the documentation is short, I have worked for a few days in VGA mode before finding The trick. The advantage of HDMI is that the sound through the speakers of the screen with a single connection. I am very satisfied with my purchase.
