\"EDID<\/figure>\n\n\n\n

In this post, we tell you exactly what you need to do in order to make sense of your monitor’s extended display identification data (EDID) on your Raspberry Pi.<\/p>\n\n\n\n

Note: previously, a function to read the EDID used to be available with the standalone version of PiDoctor. This version has been discontinued, and the functionality to read the EDID is not implemented into the new PiCockpit <\/a>PiDoctor <\/a>app yet, therefore I’m going to give you manual instructions how to read the EDID in this article.<\/p>\n\n\n\n

PiDoctor includes output on monitor modes<\/h2>\n\n\n\n

Before we dive into how to extract the EDID on your Raspberry Pi, note that the new PiCockpit’s<\/a> PiDoctor <\/a>app includes a lot of output you would expect by reading the EDID as well (supported resolution modes, monitor name, audio support, …), here are two sample screenshots:<\/p>\n\n\n

Read the EDID under Raspbian \/ Raspberry Pi OS<\/h2>\n\n\n\n

Run the following command on the command line:<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
tvservice<\/span> <\/span>-<\/span>d<\/span> <\/span>\/<\/span>tmp<\/span>\/<\/span>edid<\/span>.<\/span>dat<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
<\/p>\n\n\n
\n
\"run<\/figure>\n<\/div>\n\n\n
<\/p>\n\n\n\n
This will create edid.dat in the \/tmp directory. <\/p>\n\n\n\n
Note: on a Raspberry Pi 4 and 400, two displays can be attached using the microHDMI ports. In this case, you would want to specify the display to read the EDID from:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
tvservice<\/span> <\/span>--<\/span>list<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
<\/p>\n\n\n
\n
\"tvservice
tvservice shows the attached displays<\/figcaption><\/figure>\n<\/div>\n\n\n
<\/p>\n\n\n\n
Then pass in the device ID, of the display you are interested in, like so:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
tvservice<\/span> <\/span>--<\/span>device<\/span> <\/span>2<\/span> <\/span>-<\/span>d<\/span> <\/span>\/<\/span>tmp<\/span>\/<\/span>edid<\/span>.<\/span>dat<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Decode EDID using edidparser<\/h2>\n\n\n\n
You can run edidparser on this file (if it is not on your system, please install it first):<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
edidparser<\/span> <\/span>\/<\/span>tmp<\/span>\/<\/span>edid<\/span>.<\/span>dat<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
This will give you a lot of output, for example on my monitor, it gives:<\/p>\n\n\n\n
