3 devices can connect and select one or the other of the inputs. For example connect on the same screen a computer + a video-camera surveillance and analog VCR. VGA output side, several screen resolution can be switched sequentially. It is also possible to adjust contrast, brightness and color temperature. Picture quality decent, but nothing more, which makes sense since we are VGA, not HDMI. I lai not dismantled but the physical construction looks rather neat. Supplied with power supply unit 5V 1A sector and s-video cable. Very pleased with this converter and Amazon services.
