Hi,

I'm currently trying to setup a friend's PC. Configuring X is a slight
problem. The monitor is a 15'' flat screen one, named "LB500" (sic). No way
to retrieve the monitor manual with the specs.

Normally, in such a case, I boot a copy of Knoppix and take a peek
at /etc/X11/Xf86Config-4, only I haven't got it here, and there's no way
this afternoon to get one (far-off countryside hereD).

I tried xorgsetup, and that's what X "guessed" so far:

HorizSync 31.0 - 61.0
VertRefresh 56.0 - 0.0

0.0 is obviously wrong. Tried to replace it with a roughly estimated 75.0
(known to work on _some_ 15'' flat screens), but the screen went black. And
no way to find the specs via Google.

1) How reliable are the three guessed values besides 0.0?

2) How to get the max VertRefresh?

Any suggestions?

mmm... googling for 'lb500 monitor' suggests that you may be dealing with
an LG Electronics Flatron:

<http://www.preissuchmaschine.at/product_310619.html>

if it's the one, i'm sure <http://www.lge.com> will have the specs you want.

LG has a monitor sold as the LB500 and also as the L1510S. The manual can
be found at http://www.lge.com/support/manual_gcsc.jsp You will have to
work your way from there. I selected Europe and France, as N.A./USA
produced nothing. For what it's worth, the manual says the specs are:

Horiz. - 31-61kHz (automatic)
Vert. - 56-75 Hz (automatic)

Pretty close to what xorgsetup gave you, and exactly what failed when you
tried it. Is this monitor known to actually work?

My laptop's lcd screen has a fixed VertRefresh of 60.0 for all
resolutions. My xorg.conf has:

HorizSync 31.5 - 75.0
VertRefresh 60.0 - 60.0

But mine is a Dell Inspiron 5150 at 1600x1200.
