Is the Hisense U6 Mini-LED good for gaming?

Yes. It has a 144Hz native refresh rate and HDMI 2.1 inputs, which support high frame rates from current consoles and PCs. It lacks the brightest HDR punch of premium models but handles motion well.

How does the U6 compare with the Hisense U7 and U8?

The U6 is the entry Mini-LED model. The U7 and U8 are brighter and have more local dimming zones, so they handle HDR highlights and bright rooms better. The U6 keeps Dolby Vision and 144Hz gaming at a lower tier.

Does this TV run Fire TV or Google TV?

This model runs Fire OS, Amazon's smart TV platform, with Alexa built in. Other Hisense models use Google TV, so check the listing if you prefer that interface.

Does it support Dolby Vision and Dolby Atmos?

It supports Dolby Vision HDR for picture. Dolby Atmos passthrough depends on the connected soundbar or receiver, since the built-in speakers are basic.

What size is this TV and will it fit my wall?

It is a 75-inch class screen, roughly 65 inches wide before stand or mounting hardware. Measure your wall and viewing distance; a 75-inch set suits rooms with about 8 to 12 feet of seating distance.

Do I need a soundbar with it?

Most owners add one. The built-in speakers are fine for news but lack bass and impact for movies, so a soundbar or AV receiver improves the experience noticeably.
