The TV also has VGA input, so I connected the HDMI-VGA-converter to it and tried moving the running Chromecast from the TV's HDMI input to the converter's input - and as you can already guess, the TV showed a black screen.
Because I know that the TV as well as the converter support 1080p just fine (as well as all other forms of Full HD and normal HD input), I think it isn't a resolution-based issue but has to do with an incompatibility of the Chromecast with my specific HDMI-VGA-converter.
That's possible too, though in the case of HDfury the converter itself is an HDCP-compatible display device so it shows picture.
Technically if the converter obeys HDCP rules it should turn off its analog outputs or down scale to SD when fed an HDCP protected source.
That's a possibility too. In theory, with Chromecast sending 1080p, you should either have picture or a scrambled digital mess from HDCP decryption failure.
Black screen alone, especially at the is resolution may be the converter saying "I'm not sure what to do with this." Maybe the converter doesn't know how to handle YCbCr input and only does RGB which would explain why computer output works.
The projector's OSD now shows "640x480 @60,00 Hz". Attaching the Chromecast to my HP monitor does not work as the Chromecast decides on 1080p output at 30,00 Hz, which is not supported by the monitor.
Is there something I can do about this problem, maybe with a rooted Chromecast OS? Or is it telling me that it just won't work with my old projector?
Since I recently got one, some HDMI splitters will let you force EDID as well, so that might be a cheaper alternative than a full-fledged EDID configurator, assuming one of the modes work...
I bought this one and it supports
