RPi4 - dual HDMI inhibits boot

BrianM · July 7, 2019 at 11:55 AM

Hi all,

Have a Raspberry Pi 4 2Gb

Have a problem when connecting two HDMI monitors (using two official microHDMI leads)
RPi4 freezes during boot.

Both screens (1x1080p, 1x2160p) display rainbow splash screen, then HDMI 2 goes blank and boot process hangs.

(I am also trying to do what others have asked, which is to output to both HDMI ports for Vision in 4K from one, and surround sound via Amp on the other...)

Thanks

Brian

I'll be interested with what you find here and whether you can get it working. I had the same configuration with my Intel NUC and got it working but kept losing the menus which made it unusable.
