Title: HDMI: A64 Board not detecting the monitor max resolution
Post by: a7med3365 on August 04, 2025, 01:30:31 PM
Im using A64-OLinuXino-2Ge16G-IND, with A64-OLinuXino-bullseye-base-20231106-081613.img.7z

We had one board that we were using for sometime and it was working smoothly with multiple monitors.
Then we bought another one, same specs and installed the same image, but we are facing issues with the hdmi resolution. the board for some reason is not detecting the monitor resolution and aspect ratio automatically. it display low resolution. and i need to unplug the hdmi multiple times until the board randomly gets adjusted to the max resolution available.

is it a firmware/drivers issue? or a hardware issue?

please suggest ways to resolve this, i tried multiple fixes i found online for Linux boards in general but nothing seems to work.

thank you and best regards
