After examining raw EDID data from 2 different LG TVs I can see that both of them set bytes 21 and 22 of the EDID data in a wrong way. They both state that the display size is 160x90 cm which in turn corresponds to a approximately 72" diagonal.
So unity-settings-daemon does its job correctly and EDID from LG is buggy. Trying to find more info about it. ** Changed in: unity-settings-daemon (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to hwdata in Ubuntu. https://bugs.launchpad.net/bugs/1755490 Title: Incorrect information about display shown in unity-control-center Status in hwdata package in Ubuntu: New Status in unity-settings-daemon package in Ubuntu: Invalid Bug description: After connecting a LG 49UB850T-DA TV the following information is displayed in the unity-control-center: Goldstar Company Ltd 72" It's misleading since neither the company name nor the diagonal matches.
