Is the QN80H worth it over a regular QLED TV?

Yes, if you want mini-LED backlighting with local dimming, which gives deeper blacks and less blooming than edge-lit QLED sets. The trade-off is that step-up Neo QLED models still beat it on brightness and dimming zone count.

Does it support 4K at 144Hz for gaming?

The panel is rated for Motion Xcelerator 144Hz, and AI Auto Game Mode switches settings automatically when a console is detected. Check that your console or PC and cable support the higher refresh rate to use it.

How many HDMI ports does it have?

It has four HDMI inputs, along with two USB ports, Ethernet, optical audio out, RF and RS-232C. That is enough for a console, a soundbar and two streaming devices without a switcher.

Is Dolby Vision supported?

No. Samsung TVs use HDR10+ and the set's Neo Quantum HDR+ processing instead of Dolby Vision. Dolby Atmos audio is supported.

What comes in the box?

The TV, one remote control, a power cable and a user manual. The bundle also adds a two-year Amber Protection plan and a 200ml screen cleaner with a microfleece cloth.

What mount does the 85-inch model need?

It uses a VESA 600mm x 400mm pattern. Given the size and weight of an 85-inch panel, use a mount rated well above the TV's weight and anchor it into studs.
