I am having a strange issue: just tried using my Pocket Reform with an external display (Asus MB169CK portable monitor, to be exact). When I plug in the monitor to the HDMI output of the pocket reform, the network connection stops working (WiFi stays connected, but no internet), and as soon as I disconnect the HDMI cable, the connections resumes immediately. Strange… Any idea what could cause this?
Sorry about creating this topic twice, locked/deleted the other thread.
Do you see something relevant on dmesg in the moment this behaviour exhibits?
There is this error happening (I think) around the time hdmi cable is connected:
[ 1186.558522] rockchip-drm display-subsystem: [drm] HDMI Sink doesn’t support RGB, something’s wrong.
[ 1186.558643] rockchip-drm display-subsystem: [drm] HDMI Sink doesn’t support RGB, something’s wrong.
[ 1186.574931] rockchip-drm display-subsystem: [drm] HDMI Sink doesn’t support RGB, something’s wrong.
I think I found the culprit. The WiFi antenna was attached to the lid right next to where the HDMI port is. I think it must have caused some interference. I moved the WiFi antenna to the other side of the lid, and it seems like that solved the issue.
