H500 HDMI problems: it breaks HDMI-CEC on the TV. it prevents monitor from going into standby

I have noticed two problems with the HDMI output of the H500.
The video output works with the screens I have connected the H500 to, but there are some issues:
1) When connecting to a LG C2 TV, the HDMI-CEC functions of my other devices connected to the TV (Oppo Blu-ray player, Kodi streamer) stopped working: Powering on the external sources no longer powered on the TV. I could not control the devices with the TV remote. As I disconnected the H500 from the TV, it was OK again.
2) When connecting the H500 to a small LCD monitor, the standby function of the monitor no longer worked. This monitor usually goes into standby mode when there is no signal on the connected HDMI cable. But not with the H500. After stopping the HDMI mirror function of the H500 in the app, the screen goes dark, but the LCD backlight stays on. I need to turn the monitor off manually.
So there is something wrong with the HDMI connection, it looks like it does not handle correctly some of the usual HDMI functions. I do not have these problem with other HDMI sources on the same displays.

Same issue for me. Used to have a roku streamer plugged into my sony bravia. hdmi-cec. Plugging in the H500 hdmi stops the roku from being able to do anything.
