LG TV of different sizes listed as 72" display
Detailed description of the issue. Put as much information as you can, potentially with images showing the issue.
Steps to reproduce:
- Connect a fairly modern LG TV via HDMI.
- Open GNOME Settings
- Go to the Displays panel.
- No matter on the actual size the display is listed as 72".
This is because many (I've tested 4+) LG TVs share incorrect EDID data - the physical size (bytes 21 & 22 of EDID) is reported to be 160cm x 90cm. I guess they only care to keep the right ratio and ignore that this should contain physical size of the screen in centimeters.
Maybe it's better to ignore calculating the diagonal and display 'LG TV'? This is what the NVIDIA settings app does.
