I am guessing that the CRT is of the older type and it doesn't report
its available resolutions, unlike the LCD.
I would reinstall the EMC version that worked best on your hardware,
and then edit the X configuration file
to explicitly specify the monitor parameters (horizontal and vertical
frequency range), along the lines of
Section "Monitor"
Identifier "CM752ET"
HorizSync 31-101
VertRefresh 60-160
EndSection
and call out the desired display resolution in Section "Screen"
Section "Screen"
Identifier "Default Screen"
Monitor "CM752ET"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1280x1024"
EndSubSection
EndSection
