Library to parse extended display identification data (EDID)

pyEDID

Getting started

This is a python library to parse extended display identification data (EDID).

This project based on pyedid

EDID data format

The EDID data frame format is described in detail on the Wikipedia page.

Requirements

• Python 3.6+
• requests

Setup

pip3 install pyedid

Features

• Parsing EDID data from hex or bytes
• Embedded PNP ID registry with dump/restore to CSV file
• Updatable PNP ID registry from www.uefi.org

Quickstart

Parsing some hex EDID data with the default registry

import pyedid

edid_hex = (
    '00ffffffffffff000469982401010101'
    '1e1b01031e351e78ea9265a655559f28'
    '0d5054bfef00714f818081409500a940'
    'b300d1c00101023a801871382d40582c'
    '4500132b2100001e000000fd00324c1e'
    '5311000a202020202020000000fc0056'
    '533234380a20202020202020000000ff'
    '0048374c4d51533132323136310a0000'
)

# returned Edid object, used the Default embedded registry
edid = pyedid.parse_edid(edid_hex)

edid.name # 'VS248'
edid.manufacturer # 'Ancor Communications Inc'
edid.serial # 'H7LMQS122161'
edid.year # 2017
edid.width # 53.0
edid.height # 30.0
edid.resolutions # list with resulutions (x, y, rate), ex (720, 400, 70.0)
edid. # some other EDID data

json_str = str(edid) # making JSON string object

Getting EDID from xrandr --verbose

from pyedid import get_edid_from_xrandr_verbose
from subprocess import check_output

# getting `xrandr --verbose` output
randr = check_output(['xrandr', '--verbose'])

# parsing xrandr outputs to a bytes edid's list
edids = get_edid_from_xrandr_verbose(randr)

# parsing edid
edid = pyedid.parse_edid(edids[0])

Working with registry

from pyedid import Registry, DEFAULT_REGISTRY

# making a registry object from www.uefi.org
r_web = Registry.from_web()

# dumping the default registry to csv file
DEFAULT_REGISTRY.to_csv('/path/to/csv.file')

# restoring registry from csv file
r_csv = Registry.from_csv('/path/to/csv.file')
