Question about Computers & Internet
How do I adjust the overscan on a Commodore 1702 monitor? I have the service manual, but I've encountered two problems:
1. I can adjust the vertical size, but the vertical position will not move up far enough to center the picture. The adjustment pot (R429) is at its full left rotation. I'm guessing that fixing this will depend on whether I need more or less resistance. If more, I could replace the pot with one that has greater max resistance. If less, I have to replace one of the neighboring resistors with a lower-value one (since I've turned the pot down to zero and it isn't enough). Does this sound right?
2. I can't find the horizontal-size adjustment coil, which is documented as L503(L522).
Any help appreciated.

When your not playing games does it have this problem? You should update the drivers for the monitor and your video card and even the games for that matter, all of those have updates. Update all of these items and see if the problem still exists. You may try running a virus/spyware/other boogies scan too you never know what ilk they may spread. We'll keep the warranty thing in mind but try the above updates. http://www.viewsonic.com/support/drivers/drivers.cfm?category=1&formName=monitor let me know what happens. Tim

(I posted the latest post.) Change the resolution. (Mine was 1024 by 768, so I changed it first to 800 by 600 and then back to 1024 by 768, and it's back to normal!)
Hope that helps.

I tried this and it still does not fix my problem. I went into Menu and hit reset by mistake and that totally screwed up my monitor. Now the left side gets cutoff and no matter what I change the resolution to it does not fix it.
Whjat should I do?

OK...I paid a whole $50 for an Apex AT2702 that had [undisclosed] vertical zoom, horizontal shift, vertical shift and width issues. Before I raised hell for the person who sold it to me, I decided to first exhaust all alternative solutions.
I found that in order to tweak these settings, you have to be in service mode and must have a service manual which I can email upon request.
BE SURE TO DOCUMENT YOUR CURRENT SETTINGS SINCE ANYTHING YOU CHANGE WILL AFFECT YOUR SET'S PERFORMANCE !!!
1-Reduce your tv volume to 0
2-press the MUTE button on your original tv remote [you'll see "Mute" in red on the screen]
3-AT THE SAME TIME, press MUTE on the same remote and MENU on the tv controls.
This set your tv into service mode [there will be a red "S" at the top-center of your screen.
You'll need the table in the service manual page 47 where there are V-SHIFT, H-SHIFT, V-ZOOM, E/W WIDE default values that will need to be changed. WATCH YOUR SCREEN as you change the values to ensure you don't over do it.
If you have news ticker and sports scores issues, you'll want to be tuned to CNN, FOX, ESPN or whatever to see how your changes are applied.
If you have tv guide problems then tune to that channel or press info and see what happens when you make the changes.
BE SURE TO DOCUMENT YOUR CURRENT SETTINGS SINCE ANYTHING YOU CHANGE WILL AFFECT YOUR SET'S PERFORMANCE.
This has worked for my set and you may attempt this solution on yours at your own risk.
I'm no longer pissed off that I got a bogus tv because it now works just fine and I can see everything!
