Is there a fix for when trying to install Mu OS on the metallic Blue RG34xxSP to fix the new screen issue? When the micro SD card is inserted I can hear the OS sounds but the screen is just blank, it lit but just black.

Seems to me, its a HDMI out issue, it tries to find another screen since you can hear the OS sounds. Have you try the fix here?

There’s currently no MustardOS version that support 34xxSP devices with the revisioned screen.  
If that screen gets support, it won’t be before the next major release, muOS Andromeda. There’s no ETA for that yet.
