I had Mandrake 9.0 installed and recently upgraded to 9.2.

Running 9.0 my display seemed fine. With 9.2 I can only run a resolution
of 1024x768. I don't recall what resolution exactly I was running
with 9.0 but I know it was higher than 1024x768. The proper hardware
is registered (D5063 HP monitor, GEForce 4 video card) but when I try
to change the rez to higher values the monitor gives me an out-of-range
error while Linux doesn't seem to think that anything is wrong (from the
sounds I hear). Additionally, there are certain games that when I load
them I get the out-of-range error but the game continues to run.

Can anyone tell me what might be going on, and how to correct the
problem(s)?

In general, when you get "out of range" errors, you have something
inaccurate in your /etc/X11/XF86Config-4. Check to see if you have a
bunch of modelines. Anymore, they are often unnecessary. You might try
running the X config utility of your choice. If you feel it misses
important details, keeps a backup copy of your current one. Here's the
appropriate section of mine:

Section "Monitor"
Option "CalcAlgorithm" "CheckDesktopGeometry"
DisplaySize 360 270
HorizSync 30-95
Identifier "Monitor[0]"
ModelName "VS-195"
Option "DPMS"
VendorName "KDS"
VertRefresh 50-120
UseModes "Modes[0]"
EndSection

For the games, it's often a matter of finding the config file in your
home directory for that game -- such as ~/.bubbles, or some such -- and
check the config file. It probably has some default display parameters
that you need to change. I've never played those sorts of games myself,
so I know few details.
