rasp->TV trough hdmi switch

Mon Oct 15, 2012 9:26 am

Hi everyone!

My raspi can connect to my tv ONLY directly by hdmi cable but not trough a hdmi switch (where I got other devices linked); is that normal? Can I fix this? I'd really like to use that hdmi switch with raspberry too...

thanx for helping me...

I have used a Pi via a HDMI switch without problems.

One thing you are likely to want to do is to add the option to the config.txt file to force HDMI output. This makes sure that if you reboot the Pi while the switch does not have it selected it still comes up with the HDMI output active. If you do not have this entry then in this scenario the Pi would auto-detect it is not currently connected to HDMI and revert to the RCA composite output.

There might not be enough power coming out of your HDMI port for your HDMI switch to detect it. Try increasing the power by adding or uncommenting the line that says 'config_hdmi_boost=4'. If that does not work, try increasing that number (there is a range from 1 to 7).
