My 2.0 signal advice is for those using the built-in TV speakers or a soundbar who wonder why dialouge is so quiet.

Also, most TV’s don’t have an arbitrary slider for gamma. 2.2 is a target that many of the same model of TV should be within about 0.5 of when selected.

That advice is for those using LCD TVs with a 300 nit max brightness, not a 1000 nit OLED where BT.1886 may be more appropriate.

Set the gamma to 2.2 and make sure the eco mode is turned off.

You should also select the 2.0 audio track when available, or try the dynamic compression/volume normalisation setting.

It’s pretty new

Almost all TVs come with a power saving or eco mode enabled by default which ruins visibility. Find that in the settings and turn it off. You should also turn off motion interpolation (e.g Trumotion, Clear Motion Plus, Motionflow) so motion doesn’t become a smeary and artificial mess.

You can usually fix it by turning off power saving/eco mode and setting the gamma to 2.2 on your TV. You should also turn off motion smoothing (Trumotion/Auto Motion Plus/Motionflow/Clear Motion) so motion doesn’t look overly smooth and fake.
