I'm generally happy with this monitor for website and picture viewing, but when I insert a store-bought dvd, the video quality is really shitty in both the HDMI and VGA modes. Does anyone have this monitor and is there a way of somehow adjusting the video display so that a dvd plays clear, as it's supposed to? Right now there are visible horizontal lines and the picture is blurry. With a widescreen HDMI monitor I expect a great deal of clarity!
