There is no option present in dietpi-config to adjust the resolution.

This is intended, when you run on HW_MODEL 21 (which is x86_64) you get the driver menu instead of the resolution menu, see
https://github.com/MichaIng/DietPi/blob/5f69eebea01ce277d48333ffa21b844d5a068c3b/dietpi/dietpi-config#L118

here is an older thread with a similiar problem and a solution

Ah. I didn’t bother to open that thread up when I was searching the forum because of the word “terminal”. Thanks!

Reading through the comments of the thread you linked…I now get the feeling that this will only adjust the console/terminal resolution. The client that I have DietPi installed on runs a window manager (openbox). Will this also adjust the resolution for that?

Only open box and no desktop environment?

Correct. Openbox and LXDE are installed, but only Openbox is used.

I installed LXDE because an app that I was using had some broken icons/GUI elements. Installing LXDE seemed to fix that for some reason.

I think you need to use xrandr then.
Check with this command what outputs are available and which resolutions.
You can set then one with e.g.: xrandr --output HDMI-1 --mode 1024x768.

To make this apply on boot you can add this to the autostart of openbox:

This is what I needed to do. Thanks!

This might be a helpful tip for future readers…If you can’t be arsed to shuffle on over to the physical location of the DietPi host/client, you can still check the resolution of the attached displays remotely via SSH. Just set the DISPLAY environment variable and then run xrandr --query.

export DISPLAY=:0 # The main display is usually 0
xrandr --query
