Review on ASUS VT229H Monitor 1080P 10 Point 21.5", Touch Screen, Eye Care, Flicker-Free, Blue Light Filter, HDMI by Mike Heisler

The picture quality on this screen is excellent! However, the touchscreen function had a bug that almost forced me to return the device. Touch screen interaction is interpreted as if you touch the MAIN display, even if that screen is not configured as the main display. I connected it to a computer with two screens already connected, all touch interactions were interpreted as taking place on a completely different screen. I solved the problem by changing it to the main display, after that everything worked perfectly. So remember, if you can't set that screen as the primary display, the touchscreen functionality is useless.
