"To be totally honest, I did not even bother touching the menu and changing any kind of settings. When you first turn on the monitor and your system, the unit goes into a Auto Config mode. It configures your Clock (pixel frequency) and Focus automatically. Clock basically
controls the number of pixels scanned by one horizontal sweep. If this frequency is not correct, vertical stripes appear and the width of the screen will be off. The Focus is the horizontal direction with the same idea as the Clock. The auto config also resizes your screen with your
video input signal and adjusts the screen perfectly for you. Very convenient!"
