I would say this is especially true on an LCD, where a non-native
resolution can have some really ugly effects on fonts.

  resolution:96x90 dots per inch
  depths (7):24, 1, 4, 8, 15, 16, 32

Why is the dpi hosed when it is at 1280x960?


The dpi is calculated from the size that the monitor reports 
(339mmx271mm) and the number of dots across and down. It appears that at 
1280x1024 the monitor is reporting square pixels, and at 1280x960 it 
reports "tall" pixels.


If the "339x271 millimeters" is correct, that means that the display is 
a little taller than the standard 4:3 ratio (which would give 339x254) - 
perhaps 1280x1024 *is* the correct resolution for this monitor. I'd 
measure the physical dimensions of the monitor and if the ratio is 5:4 
instead of 4:3, use the 1280x1024 resolution. I did some research and it 
appears that this is the case for at least some LCD 1280x1024 monitors 
(for example the ViewSonic 17" has a viewable area of 13.3" (horizontal) 
X 10.6" (vertical); 17.0" diagonal which works out to 4:5 - the 
ViewSonic 19" monitors also have a 5:4 ratio.)


So it's probably best to run at the native resolution.

OK, I switched to 1280x960 and noticed something weird.  Here is the
xdpyinfo for both resolutions.

That would be a plus!  Though both of my monitors have a "native"
resolution of [EMAIL PROTECTED]  I guess changing to [EMAIL PROTECTED]
wouldn't cause any issues?

I have always used CRTs up till now.  I actually would like to trade
my monitor in for a good old 19" short-neck CRT.  I think graphics were
always more crisp on CRTs.

stupidity? Some very dumb group of persons must be responsible for 
1280x1024

I am using 1280x960 with my 17" crt and used it with my (now dead after a 
lng life) 20" crt. 1280x960 is even a valid vesa mode. So use it, if you 
want. At least with 1280x960 the aspect ratio is correct, circles are circles 
and fonts are much less ugly than with 1280x1024.

Does anyone know whey monitor resolutions go:

1024x768, 1152x864, 1280x1024

Shouldn't that last number be: 1280x960?  I have a 17" and a 19" LCD and
I have been wondering why both do 1280x1024 by default.
