Monitor resolution wrong

[Dennis Wicks <wix@mgssub.com>]

Greetings;

When I boot kernel 4.19.0-13-amd64 my monitor res is 
1024x768. It should be 1680x1050 which I get when I boot 
into kernel 4.19.0-12-amd64. Also, when I look at the xfce 
display settings when I have -13 booted it has some generic 
display listed and only the 1024x768 res. When I am booted 
in -12 the display is listed as an LG 23", which it is, and 
a bunch of different resolutions that could be used.

I have tried rebuilding the kernel and initrd to no avail. 
It looks to me like the kernel is not recognizing the 
monitor for some reason but beyond that I haven't the 
slightest idea as to where to look!

Any ideas??

Many TIA!!
Dennis
