I have this LCD (usually used with cellphones) with DSI MIPI HDMI: link.
At the moment, I can only get this device to display HDMI signal from a Windows 10 desktop. This device does not display anything for an HDMI signal from a GoPro or the Nyrius ARIES Prime wireless HDMI transmitter.
Can someone please explain why my DSI MIPI HDMI device accepts HDMI signal from Windows but not from other devices?
There are two possible reasons I could see for this. The first is that the supported resolution information is not being properly sent, resulting in a signal being sent which is not supported by the display. It is also possible that the GoPro and the wireless HDMI transmitter do not support the same resolutions as the display you are using, in which case it wouldn't be able to send a workable signal.
The second possible issue is that of HDCP. HDCP is a technology used to protect copyright video data when it is being displayed. If one of your source devices only operates with HDCP compatible devices, it is entirely possible this display is not HDCP compatible and that would prevent the display from working as well.
