I recently received a Compaq with the Compaq VGC and Compaq VGA 420 monitor. The first monitor had been dropped in shipping, and the guns were obviously out of whack. I got a new one, not obviously dropped. The new one is not very sharp, especially when cold. It is much less sharp than a Mitsubishi 1429C. Is this Compaq monitor just a lemon, or are they all this bad? Thanks, cris

Before you waste a lot of your time (and Compaq's for that matter) try adjusting the focus pot on the back of the monitor. It is likely that the vibration received during shipping was enough to make the thing go out of focus. We just received a color monitor with the same problem and I was able to cure it in a couple of minutes. The focus control is usually located on or near the flyback transformer. The flyback is the box that is located at the lower end of the thick red wire that goes to the side of the CRT. BE CAREFUL NOT TO SHOCK YOURSELF, the CRT is charged up to around 25,000 Volts when running and usually holds many thousand volts of charge when the monitor is off. Take the back off of the monitor, connect it to the computer and let it warm up a few minutes and then adjust the focus control for the sharpest picture. Some monitors will have a change in focus for a change in screen brightness, so display something that lights up quite a few of the pixels before adjusting. You may want to optimize it for text or blocky graphics depending on your typical usage patterns. P.S. The focus control usually has the word "FOCUS" written on or near it :-). ^ ^ Forrest Cook "Elvis is Everywhere - Mojo Nixon" /|\ /|\ cook@stout.ucar.edu (The preceeding was my OPINION) /|\ /|\ {husc6|rutgers|ames|gatech}!ncar!stout!cook /|\ /|\ {uunet|ucbvax|allegra|cbosgd}!nbires!ncar!stout!cook
