SOLVED: picture slighly off-screen on LCD Monitor

This has been bugging me for a while, and I finally got it solved.

I have a Mag Innovision LT501 15" LCD Monitor for my desktop, attached to a GeForce256 video card. The image on the monitor was slighlty off the physical screen, the image was up and to the right about a 1/4", and there was black space on the left and bottom. If I pressed the "auto adjust" button, it would actually become MUCH worse (it shifted half off the screen!), but I could manually adjust it back into position.

I went into my /etc/X11/XF86Config file, and changed the line:
VertRefresh 60.0 - 75.0
VertRefresh 60.0 - 60.0

Now, its all working just fine! I'm guessing my monitor didn't like 75Hz very much, and couldn't make sense of the input signal.

Interestingly enough, the installer identified my monitor as:
VendorName "Monitor Vendor"
ModelName "LT-541"
So, it got it close as the LT-541 rather than the LT-501. Whom would I contact if this is simply a database of known hardware? Or did my monitor erroneously identify itself? Oh well....

I wanted to document this in case anyone else was having similar problems!

There is a process for getting monitors added to the database.

First, run: sudo /usr/sbin/ddcprobe

This will show how the monitor identifies itself during a hardware probe (if at all). If the monitor gives no ID during ddcprobe, it means the monitor will not be able to be auto-detected, but users will still be able to select it from the monitor database.

Second, look in /usr/share/hwdata/MonitorsDB to see if there is already an entry for your monitor.

If an entry exists for your monitor, verify the sync rates against what is published in your monitor's manual. (If you don't have the manual, you might be able to download it from the manufacturer's website.)

If the information is missing from MonitorsDB or is incorrect, file a report in Fedora's bugzilla similar to this one:
Be sure to include the output from ddcprobe.

HTH, Jack
