Raspberry Pi Turn Tv On/Off CEC – Tim Leland

Posted by jpluimers on 2021/10/13

[WayBack] Raspberry Pi Turn Tv On/Off CEC – Tim Leland (with some quote fixes) via [Archive.is] Brad Fitzpatrick on Twitter: “lol tear (from )… “:

Install cec-utils

Once everything is installed you should be able to control the tv using the command below:

  • Turn tv on: echo 'on 0' | cec-client -s -d 1
  • Turn tv off: echo 'standby 0' | cec-client -s -d 1
  • Set active source: echo 'as' | cec-client -s -d 1
  • Tv status: echo 'pow 0' | cec-client -s -d 1

Troubleshooting Tips:

  • Make sure your tv supports cec and that it is enabled. Tv manufactures call CEC by different names so you may have to do some research depending on your brand.
  • Make sure you are using a new hdmi cable that is at least HDMI 1.2a

Different names for HDMI CEC

  • Samsung – Anynet+
  • Sony – BRAVIA Link or BRAVIA Sync
  • Sharp – Aquos Link
  • Hitachi – HDMI-CEC
  • AOC – E-link
  • Pioneer – Kuro Link
  • Toshiba – Regza Link or CE-Link
  • Onkyo – RIHD (Remote Interactive over HDMI)
  • LG – SimpLink
  • Panasonic – VIERA Link or HDAVI Control or EZ-Sync
  • Philips – EasyLink
  • Mitsubishi – NetCommand for HDMI
  • Runco International – RuncoLink

PC to TV HDMI image too large for screen – [Solved] – Graphics Cards

Posted by jpluimers on 2020/03/23

Someone Somewhere said:

It’s a setting in the TV. Look for terms like ‘overscan’ , ‘pixel perfect’, ‘1:1’, or similar. Usually under the HDMI settings for that input.

In my case (my mother’s Samsung), the original setting was 16:9 which failed. What works is screen fit. Go figure.

Replace Boxee by Raspberry Pi as most TV support doing video+USB keybard over HDMI

Posted by jpluimers on 2016/02/22

If for instance your Boxee gets old or breaks down, you can use a Raspberry Pi as a replacement with Kodi as media player.

This combination will understand the Video+USB over HDMI which most TV supports officially named HDMI-CEC , but most vendors “invented” their own names (see list below).

The core is the kodi support for CEC.

Basically it comes down to using three cables going to the Pi: Power from TV (or some other source), HDMI to TV, and wired Ethernet. And a distribution for RaspberryPi containing kodi will work, for instance from OpenELEC Mediacenter – Download: Raspberry Pi Builds

Chad MILLER has more details on how to get this to work: My Boxee box is getting old, but I knew of no replacements. The problem is I …

Names known for HDMI-CEC via Wikipedia:

Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), E-link (AOC), Kuro Link (Pioneer), INlink (Insignia), CE-Link and Regza Link (Toshiba), RIHD (Remote Interactive over HDMI) (Onkyo), RuncoLink (Runco International), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).

Because of the naming, turning on CEC can be confusing: How to Enable HDMI-CEC on Your TV, and Why You Should
