I cannot for the life of me figure out how to get this monitor to fit the image to the size of the screen. I have about 2 inches of black space around the outer rim. I have it set at the 1900 resolution, everythings clear but it is just not fit to the outside wall. Any suggestions? I cannot auto adjust while in HDMI, I have gone through every setting I could find in the menu on the monitor and still nothing work.s.
