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.
