Does the TCL S55LR have local dimming?

No. It uses a direct LED backlight without local dimming, so black levels are average for its class.

Is it good for gaming?

It handles casual console play, but it lacks the high refresh rate and gaming features of TCL's step-up models.

What streaming apps does it include?

It runs Roku, so it has the Roku Channel plus major apps like Netflix, YouTube and Disney+.

Yes, it accepts HDR content, though peak brightness is modest compared with premium sets.

Yes, it has standard VESA mounting points, so most 50-inch wall mounts fit.

Do I need a soundbar?

Most owners add one. The built-in speakers are fine for news but thin for movies.
