Is the Hisense U75QG worth it over the U8 series?

The U8 models are brighter with more dimming zones and better anti-glare handling. The U75QG keeps most of the Mini-LED experience for less, so it makes sense if you want a big bright TV without flagship extras.

Does the U75QG have HDMI 2.1 for gaming?

Yes. It includes HDMI 2.1 inputs with high refresh rate support for consoles and PCs, plus game-mode processing to keep input lag low.

Do I need a soundbar with this TV?

The 2.1.2 Atmos speakers are better than most built-in TV audio and add height effects, but bass is limited. A soundbar or subwoofer improves movie sound noticeably.

How does it handle dark scenes?

Mini-LED dimming gives good black levels for an LCD, but reviewers report some blooming around bright objects on dark backgrounds. A bias light in the room helps.

What smart platform does it run?

It runs Google TV, which covers the major streaming apps and supports voice search and casting.

Is 75 inches too big for a normal room?

For a typical living room with seating around 8 to 10 feet away, 75 inches is a good fit for movies and sports. Closer seating can make standard-definition content look soft.
