Is this TV good for gaming?

Yes for casual console play. Game Mode Plus runs 4K at 60Hz with Variable Refresh Rate and Auto Low Latency Mode, which keeps lag low. It does not offer 120Hz, so competitive players on newer consoles will want a faster panel.

Does it support Dolby Vision or Dolby Atmos?

The A6 Series relies on standard HDR formats and DTS Virtual:X audio processing rather than Dolby Vision or Atmos. Check the specific input and format support if those matter to you.

How does it compare with Hisense's U8 series?

The U8 uses mini-LED backlighting with far higher brightness and better contrast. The A6 is a simpler direct-lit set, so it wins on size for the money while the U8 wins on picture quality.

What is FilmMaker Mode?

It turns off motion smoothing and adjusts picture settings to approximate how the director mastered the film. It is best for movies in a dim room, not for sports.

What comes in the box?

The TV, a voice remote, a stand and the power cable. A wall mount and HDMI cables are not included.

Is the 85-inch size hard to fit in a room?

It needs a wide wall or stand and roughly two viewers sitting several feet back to avoid seeing pixel structure. Measure the space and viewing distance before buying.
