hdmi_drive=2 changes colors

[spwx]

Hello, I am trying to get sound to work on my TV. I have two HDMI inputs labled:

HDMI 1 (DVI)
HDMI 2 (ARC)

I've tried both and can only get sound to work when adding "hdmi_drive=2" to the /boot/config.txt file.

On reboot boot i can get sound to work however it really fades the colors on the screen. Is there anyway to get both audio and vibrant color at the same time?

Thank you!

Also is there a way to force the raspberry pi to tell me what hdmi_mode and hdmi_group it is auto detecting?

Thank you!

The "tvservice -s" command will show the current video type, group and mode.

Example on my main Pi

Code: Select all

rpdom@raspi:~$ tvservice -s
state 0x120016 [DVI DMT (35) RGB full 5:4], 1280x1024 @ 60Hz, progressive

So you can see I'm running group DMT (into a DVI-D monitor) and mode 35.

Thanks a lot guys! I learned a lot.

Basically i just tried a bunch of different hdmi_modes. They all had the same problem.

Whenever i set hdmi_drive=2 the colors at the terminal are faded.

HDMI is confusing, isn't it? Not least because TV manufacturers have their own ideas about what you should be wanting.

It sounds like the Pi is sending one of the "limited" encodings, while the TV is expecting "full"

Thanks for the help, but no luck with those either. I tried all five.

I can't quite tell but it looks like only my terminal colors are being effected and X windows is fine. For now ill just set hdmi_drive=1 and use a head set for sound.
