Is this TV good for gaming?

Only casually. It has no VRR or high frame rate mode, so fast console games will show motion blur and screen tearing more than on a gaming-focused set.

Does it have local dimming?

No. It is a standard edge-lit LED panel, so dark scenes look grey compared with sets that dim zones of the backlight.

Can I mount it on the wall?

Yes. It is VESA compatible and the panel is about 1 inch deep without the legs, so it sits close to the wall.

Does it support soundbars?

Yes. It has HDMI ARC and eARC plus an optical output, so most soundbars connect directly.

What is the difference from a consumer Samsung 4K TV?

This is a hospitality model. It runs Tizen and shows 4K, but it skips gaming features and some picture settings found on consumer sets like the AU8000.

The TV, its stand legs, remote and power cable. Check the listing for the exact remote type, since hospitality units sometimes ship with a simpler one.
