I neglected to say the Samsung monitor (which exhibits the problem)
is a flat screen monitor (SyncMaster 2253LW). The other monitor I
used to test is the CRT, and it works fine with Linux and
Windows. The flat screen quits after complaining a few times with
the pop-up window. The setting 1024x768 is listed as one of the
possible settings in the brief manual that came with the monitor so I
would think it would run OK with that setting... unless there is some
other adjustment I don't know about.

Usually LCD monitors work best at 60Hz, whereas CRTs are run higher,
70, 75, 85, or more to eliminate flicker. LCDs don't have any
flicker, so the 60Hz standard is fine.
Check that setting first, perhaps resetting resolution/refresh while
running the CRT so you can see things... :)
Linux, especially an older version, might not check the display and
change accordingly, whereas Windows has since probably windows 98.

One of my computers is an old PC with dual boot Windows and Fedora
2.6 (old machine.. haven't used it enough to update). I attached a
new monitor Samsung 21.6" in analog mode. It works fine with
Windows running at 1024X768. When I booted into Fedora (also set
at 1024x768), the monitor worked at first. Then a message window
from the monitor popped-up. It said "Not optimum mode, Recommended
mode 1920x1200".
This happened after I had time to log in. I pushed the auto button
on the monitor (for lack of knowing what else to do... it adjusts
the image placement on the screen) and the monitor-generated pop-up
window went away temporarily... but it soon come back. A short
while later the screen went blank. I kept the computer running,
disconnected the monitor, and connected an old CRT monitor. The
Linux screen was still there and everything worked fine with the
CRT monitor. I shut down, reconnected the new monitor, and
repeated the process with the same results. Any ideas why I can't
use the new monitor with Linux? Why would the monitor work during
Linux boot and for a short after login, but then quit? As
mentioned, it works fine under Windows indicating the monitor is in
good condition.
