What to do if my Compaq Monitor has an abnormal picture?
If your Compaq monitor shows an abnormal picture, try the following: For a standard signal, perform a "GEOMETRY-RESET" or "ALL RESET". With non-standard signals, adjust HORIZ-SIZE, VERT-SIZE, HORIZ-PHASE, and VERT-POSITION. Note that the monitor may not be able to get a full-screen image depending on the signal; in this case, select another resolution or vertical refresh timing. Also, ensure that the "VIDEO LEVEL" is at the appropriate position for your graphics adapter output (0.7v or 1.0Vp-p). Remember to wait a few seconds after adjusting the size of the image before changing or disconnecting the signal.
