Summary: Before you buy this product, please be aware that this product only has VGA port for PC. For a 1920x1080 monitor, it means tons of blurring and shadowing. If you are used to using dvi on high resolutions, getting back to vga is never an option. You may then think that the HDMI port is going to solve the problem. This was what I thought too, but trust me, the HDMI is NOT for PC. I connected it to my computer using HDMI cable.
