I recently bought a Waveshare display to connect my Raspberry Pi (RPI) to it for showing Home Assistant info. The display also has a second HDMI port which I would like to use to connect my Chromecast Google TV. However, the default resolution (EDID data) is 1080x1920, so by default a portrait mode display. In my RPI, I can rotate the screen to 1920x1080. But I'm still looking for a solution for rotating also the Chromecast GGTV.
I already tried to install a "screenrotation" app, but nothing happened. I also tried to connect to the screen through adb and run some commands, but not the result I was hoping for (I got a message that the Chromecast did not support that resolution).
Today I found on the internet an EDID emulator. Could this be a solution? These are the EDID timing parameters of the display:
Pixel Clock H Addressable H Blanking V Addressable V Blanking H Front Porch H Sync Width V Front Porch V Sync Width H Image Size V Image Size H Border V Border 141.12 1080 120 1920 40 40 20 2 5 1080 1920 0 0 Any idea how to solve my problem (if there is a solution)?
