You only ran the first half of the command. 'get-edid' finds the DDC and if there's EDID to be found outputs it as found - which means in some unreadable to humans binary format - to standard output. By sending that output through a pipe to 'parse-edid' you get something human-readable. The only readable information in the output you posted is 'LG TV', which seems like it is the same thing Windows tells you about the device. There should be more, way more information (output for the external display connected to my system to give you an idea):
Code:
$ get-edid |parse-edid
This is read-edid version 3.0.2. Prepare for some fun.

The line I set bold gives the physical size of the display in mm; some programs make decisions regarding their graphical layout based on that data.
