Display 13.2 Module (M126) issue with a HDMI display

[admiralmaggie]

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:

Hello@admiralmaggie

It depends on the type of HDMI Display.

Not Display Module 13.2, but...
For ATOM Display and TOSHIBA REGZA：
(1920/4,1080/4,24);
(640,360,60);
(320,180,60,1280,720);
(320,240,60,3204,2403);
(500,300,60,1280,720);
(500,300,24,1920,1080);
(480,320,24,1920,1080);
(480,320,60,1280,720);
(500,300,60,1280,720);

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

Hi,@admiralmaggie,
Resolution and refresh rate depend on the monitor being used. If variable, the resolution can be changed.
However, some monitors have a fixed resolution and refresh rate, in which case it is necessary to match the monitor specifications.

Warning
The display 13.2 , in the 1920x1080 mode, seems limited to 24 frames/seconde
It does not accept 50 or 60 frames.
One of my monitors does not accept 24 frames/seconde.
