monitor adjustment to remove shadow

by bwhitesell / August 6, 2006 10:19 AM PDT

I have a 5 year old Gateway EV910C 19 inch CRT monitor that produces a shadow to the right of all text and graphics. To date I've done the following to diagnose the problem:

1) I've tried several different resoultions and refresh rates from the Windows XP Display settings. All produce a shadow.

2) I've tried to adjust this with the On Screeen Display (OSD) control using the dial wheel on the front of the monitor without any success.

3) I've connected another monitor and found that my graphics card is not the source of the problem. The other monitor at the same resolutions and refresh rates does not show the shadows.

4) I pulled the case off the monitor and found the vertical and horizontal focus controls. I tweaked them but I still have about a 1/16th inch offset to the right which produces a shadow effect. The internal control labeled ''Screen'' has been glued to prevent adjustment.

The picture is bright and sharp with the exception of this annoying shadow. I'm guessing the Red, Blue, and Green guns are misaligned.

Any suggestions on how to fix the problem, other than buying a new monitor?

It appears you've done all you can with adj'ments of the monitor. Since this is a 5yr. old crt. you are now experiencing the age of the monitor. Only a true repair is going to fix it and/or replacement. You may not want to buy a new monitor but if the repair cost exceeds 50% of new, then you decide. I wouldn't fiddle too much the innards any more, you're only going to really whack it up, of course that's a last resort item to do. I suggest you get some diag displays and tweek from those and not the OSD ones. The shadow could also be the result of tweeking in the extremes to get anything as the monitor is worn out, thus you'll never get rid of it except for a repair. You can find used crt's at the Sal. Army or Goodwill as users update to LCDs, etc. for cheap.

Even though this is an old post, users refer to it to fix their problem. Please note, as the OP said, he had tried adj. with the monitor as follows:
4) I pulled the case off the monitor and found the vertical and horizontal focus controls. I tweaked them but I still have about a 1/16th inch offset to the right which produces a shadow effect. The internal control labeled ''Screen'' has been glued to prevent adjustment.

Since, the above didn't correct the problem, i like to point out, then the monitor was still "plugged in", very bad. The AC even with power-OFF provides a shock value all its own. Yet, he tried another monitor to check this which suggests he had to "unplug" to get the other monitor connected. Unless, i missed something, it should have corrected itself when the monitor was returned. maybe it did, but following the 1-4 steps, didn't work???

Enjoy, the fix if that what it takes to make it work. Electronics does have mysteries. -----Willy Shocked

Unplugging monitor and replugging in worked for me too. I had just downloaded a Java update and thought that was to blame, but the screen looks good again. Thanks!

When you say your unplugging it, and plugging it back in, are you unplugging the power chord or the Video cable? Got to know?

Replaced the old VGA cable. Shadow gone, works good now.
(Mine was a 22 inch LCD screen connected to a laptop. Shadow was on right side of text)
Thanks for this useful discussion.

Pixel Clock + Phase
by nisarg89 / June 4, 2016 10:40 PM PDT

I created an account just so that I can come here and post my reply.

It was quite frustrating to come here, read that simply unplugging and plugging in worked for someone, then read that it worked for a gazillion of other people too, try it 1000 times, only to see it not work! (It's surely a legitimate solution, as it worked for so many people. I guess my problem was just a different one.)

In any case, for me, changing the monitor's preset mode to text made it slightly better. But what finally sealed the deal was manually adjusting the Pixel Clock and Phase settings in the monitor. See this page for more info:
