Twinview with a monitor that doesn't support EDID

davelaser · 11-24-09, 10:21 AM

Hi everyone.

I want to use twinview with my lcd and a Hitachi HM-4520 monitor that is too old to support EDID.

The appropriate modeline is:

Modeline "1440x1080@72" 178.26 1440 1472 2144 2176 1080 1101 1114 1135

I have put a section like this in my xorg.conf:

Code:

Section "Monitor"
    Identifier     "Monitor1"
    Modeline "1440x1080@72" 178.26 1440 1472 2144 2176 1080 1101 1114 1135
EndSection

But nvidia settings only gives me the standard resolution options for a monitor that it gives when it doesn't know any information about what modes it supports. How can I use this monitor at it's native resolution with twinview?

Thanks
Sam

In fact if someone just has a working xorg.conf that uses modelines to manually configure a device that would help a bit even if it doesn't use twinview.

Annoyingly this monitor works perfectly in windows - I guess it does do EDID but it doesn't work with the linux driver.

Please see the forum sticky posts about how to generate a bug report, paying special attention to the instruction on producing a verbose mode validation log.
