Description Alan Coopersmith 2004-05-31 17:31:07 UTC 
When letting Xorg autoconfig itself, it chooses a non-native default resolution
for the ViewSonic VX2000 LCD.  It picks a 1400x1050 resolution with a 74.8 Hz
refresh rate, instead of the native 1600x1200 at 60Hz, because the
autoconfiguration template in
xc/programs/Xserver/hw/xfree86/common/xf86AutoConfig.c specifies
"TargetResolution 75Hz" - removing that line from xf86AutoConfig.c causes it to
pick the correct default resolution, but may cause CRT monitors to use a lower
than ideal refresh rate - perhaps this property should only be set by the
autoconfig code when the VESA EDID does not report DFP mode?
Comment 1 Erik Andren 2006-04-04 05:23:23 UTC 
Is this still an issue with a current version of xorg?
Comment 2 Alan Coopersmith 2006-04-04 05:54:49 UTC 
Yes.   Bug is still present in modular CVS head.
Comment 3 Luc Verhaegen 2006-04-04 06:05:32 UTC 
Nobody will die from looking at 60Hz on a CRT. I'd have to look into
xf86AutoConfig.c but maybe that line should just be removed.

Anyone wanting a higher refresh rate for his CRT can always use the conf file or
wait for #5386 to happen (or for further advances in X configuration).

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

Should be fixed in HEAD.
