It doesn’t show the screen resolution. But still the hardware should be able to run Chrome properly.
Can you press Home button on the server laptop, and go to chrome://gpu on the address bar.
It will show you if hardware acceleration is enabled?
Also if you know how to ssh into the laptop, I can share my /opt/volumiokiosk.sh file
Or read this thread (I have a similar X86 machine, slightly newer and had problems running hardware acceleration)
Regardless pressing CTRL and Minus few times should get your resolution lower CTRL and Plus higher.
