xorg.conf for QNIX QX2710 27"?

I need to configure xorg.conf because these cheap monitors does not have an EDID id (or something similar). So what values should I use? Anyone knows? I have once destroyed a monitor many years ago when I experimented with xorg.conf, so I am hesitant to experiment again.

I have found these posts:

"got my monitor working now using the settings cor35vet have posted, it worked when i changed option "DPMS" "true" to "DPMS" "false" and lowevering the pixelclock to 327.6 (one or both of them),"

This apparently works for dual monitor for QNIX and another screen:

Ok, problem solved, thanks to Cheetoz
Here is my xorg.config file for Solaris 11 Express, and QNIX QX2710
http://hardforum.com/showpost.php?p=1039897942&postcount=190
Everything works great. Disable graphics with
# svcadm disable gdm
modify the xorg.conf file and then enable graphics again with
# svcadm enable gdm

Here is the xorg.conf file for future references:
