Raspberry Pi 3 no HDMI output

Tue May 17, 2016 9:43 am

Hi
My 2 Raspberry Pi 3s won't display on my HDMI monitor (with 2 different HDMI cables) or my HDMIPi screen. Shows as 'no signal'.
Yet if I remove the sd card from the 3 and place it in my Raspberry Pi 2 it displays fine. So it's not the HDMI settings in config.txt!
BUT the Raspberry Pi 3s will work with my Motorola lapdock via HDMI!!

Help!

reply to RogtheDodge on RPi3 no HDMI out
So recommended is to retry connection of RPi3's HDMI exactly and also checking voltage of Power Supply enough for Pi3.

Tried to connect again. 1st using Raspberry Pi 2 to HDMI all fine. Unplugged peripherals and sd card put into Raspberry pi 3 no signal on HDMI. The PSU I am using is 2.5 amps
Could the Pis be faulty?

You wont get any hdmi output without a valid sdcard.
Are you sure your sdcard image is new enough for Pi3?
Latest Jessie from here should be.
Report output of "vcgencmd version" (on Pi2) to be sure.

Hi Dom
Thanks. You put me on the right road. The latest 'Jessie' did get me HDMI access. What wouldn't load HDMI was the latest 'BerryBoot' v13-03-16 for Pi 2 & 3. I needed this for my WD Pi-drive.
What's odd is that 'BerryBoot' and my LapDock did give me HDMI output! Very strange.
Thanks again
