Hi Ben, Success! Booting up on the Dell U2414H now has the screen centered. GUI windows and fonts are a little erratic.
a) tty1-6 now has smaller (regular) font b) MATE Terminal, emacs and pluma have regular fonts c) Xemacs, XTerm & UXTerm have small windows with small font Tried to run the command again and the response was: # update-initramfs -u > update-initramfs: Generating /boot/initrd.img-4.19.0-4amd64 W: Possible missing firmware /lib/firmware/amdgpu/vega20_asd.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_sos.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_rlc.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_mec2.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_mec.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_me.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_pfp.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_ce.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_sdma1.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_sdma.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_uvd.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_vce.bin for module amdgpu W: Possible missing firmware /lib/firmware/amdgpu/vega20_smc.bin for module amdgpu So I now have a decent monitor display on the Dell but the older Acer X223w still plays up. The screen has shifted to the left by 10% so the Mate menus are largely hidden. I doubt there are many users with such ancient monitors but Debian is used by many downstream distros and you may wish to find a solution for the problem. If so I will be happy to cooperate. Otherwise you may consider the report closed. Thank you so much for your help.
