How to find out the diagonal of the display from the console?

Question

linux

Hey!
How to find out the diagonal of the display from the console?
I found the read-edid utility .
After the command :
get-edid | parse-edid
gives the answer:

This is read-edid version 3.0.1. Prepare for some fun.

Looks like no busses have an EDID. Sorry!

Looks like VBE was successful. Have a good day.

I can't use how to extract data from grep because it sees all the text as one line.
How to pull out data using awk or maybe there is another utility for displaying the diagonal?
I think regular expressions should be used here, but I'm not very familiar with it.
RESOLVED!
How did you know the diagonal

edid=`get-edid | parse-edid`
echo -e "$(edid)" | grep 'DisplaySize' | awk '{print sprintf("%,1f". sqrt("$2*$2+$3*$3")*0.04)}'

Answer 1

edid=`get-edid | parse-edid`
echo -e "${edid}" | grep 'DisplaySize' | awk '{print $2"x"$3}'

340х190

Answer 2

grep DisplaySize| awk {'print$2,$3'}
