I have tried changing the screen resolution of my 2.4" monitor to 320x240, but no luck.
Here is my config.txt
I have no success changing the screen resolution. My monitor is connected via the GPIO pins, not the HDMI cable.
I have read somewhere that adding/uncommending these lines will help:
hdmi_force_hotplug=1 hdmi_cvt=320 240 60 1 0 0 0 hdmi_group=2 hdmi_mode=87
But it hasn't, it's still the same resolution as it was before.
Here are screenshots how my screen looks like, as you can see, the resolution doesn't fit the screen size:
