Subject: [bristol] Digimate Monitor - Anyone a Modeline Expert!?
Message-ID: <568D7B2F.5030602@virginmedia.com>
Content-Type: text/plain; charset=utf-8; format=flowed
Hi,
I recently dismantled a Digimate 20" L-2041W that was beginning to
vibrate which I sorted. On reassembly I cannot get it to sync and it
shows part of vertical distorted on the right of the screen.
Re-checked assembly/connections 3 times but still the same. Checked DVI
leads and all works with another monitor so thought I had somehow
b**ggered it!
On further research I noticed the VGA boot is also a problem in that it
does not show all the screen and its horizontal sync is unstable.
I am on Fedora 22 and the display is showing "NITS Technology Inc 22
inch" and has no resolution settings to tweak.
I remember this monitor did not give its EDID and I had to put in a
modeline to get it to work (Dave S - if you still have details it would
help).
I think there is nothing wrong with the monitor but need to sort out a
modeline to get it working and why I am getting a "NITS 22inch" unless
that was something to do with original settings.
Maybe I need to add something after the modeline settings to stop it
picking up "NITS"!?
FYI I have made an 00-myfile.conf in /etc/X11/xorg.conf.d that just has
a modeline for 1680x1050, do I need one for vga or should it just work!!?
Thanks

The output from the BIOS and GRUB should sync without any special treatment. If they don't, the monitor is operating out of spec.

I'm not a modeline expert but I have composed them manually in the past.
IIRC I read:
http://www.tldp.org/HOWTO/html_single/XFree86-Video-Timings-HOWTO/
Somewhere (linked from this?) there was an online modeline calculator as
well. The monitor I was working with seemed to handle me screwing
around with the numbers manually as well.

David F has already posted the previous details; I still have two of these monitors, and they're working fine - in fact, I recently installed Linux Mint 17.2 (MATE) on a PC connected to one, and it "just worked".

I thought you gave me Xconfig entries when we first bought them as they
did not work out of the box!?
Does your "Display" state its a "Nits 22inch"?
Is it picking this up from the monitor EDID?
A couple of questions to help me understand things!:
IS the VGA opening boot lines affected by the modeline or EDID from the
monitor? If not then there is not much I can do!
If there is a modeline entry will this override the EDID?
