I have 40PFL6636T/12 with the newest firmware available from your website(14.96, if I recall correctly).
Usually I have the TV connected to my laptop via HDMI and your support website for the TV recommends that I use the "PC mode" while using it as a monitor for the computer. Unfortunately this option is greyed out in the menu and I can't choose it.
Why is this and how can I fix it?
