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

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

Getting EDID from xrandr --verbose

# parsing xrandr outputs to a bytes edid's listedids=get_edid_from_xrandr_verbose(randr)
# parsing edidedid=pyedid.parse_edid(edids[0])

Working with registry

frompyedidimportRegistry, DEFAULT_REGISTRY# making a registry object from www.uefi.orgr_web=Registry.from_web()
# dumping the default registry to csv fileDEFAULT_REGISTRY.to_csv('/path/to/csv.file')
# restoring registry from csv filer_csv=Registry.from_csv('/path/to/csv.file')
