Thanks @macsbug . In addition to resolution and refresh rate, is there anything else I can play around with?

Hello,
I have one of the new Display 13.2 Modules (M126). I've been able to get the example program working with a few different HDMI displays but I have a smaller HDMI display where I cannot get to display anything. This is a new module and I can't find any information on troubleshooting steps. Besides resolution and refresh rate, what other settings can I play around with?

static M5ModuleDisplay display(800, 480, 60);

Thank you in advance!

Here is the debug log output:
