Description of problem:
When selecting generic crt->1024x768, the horizsync appears at 31.5->57.0 This
drives my monitor out of sync. Adjusting the max sync to 55 allows me to view in
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. start X
<mharris> davej: What brand/model of CRT?
<davej> "Shamrock Tech co Ltd" model C407L
<davej> mharris: it doesn't talk ddc
<mharris> davej: "shamrock C407L" on google turns up nothing found. ;o/
<davej> mharris: yeah, this is donkeys years old.
<davej> mharris: its the last 15" monitor I have too I think
<mharris> davej: No DPMS support either I presume?
<davej> no epa logos or the like on the back of it..
A new entry should be added for this monitor, based on "generic"
but with the timings tweaked.
Note that this didn't get fixed before GA, and is still broken

The proper thing to do, is to add an entry to the monitor database
for your specific monitor. Changing the generic default is a bad
I've added the following line to MonitorsDB in hwdata 0.108-1
Shamrock; Shamrock C407L; 0; 31.5-55.0; 50-70
