Is the TCL 115QM891G worth it?

If you have a wall and room for 115 inches and want projector size without a projector, it is one of the few options. For a normal living room, a smaller QM8 or QM7 costs far less and looks nearly as good.

How does it compare with a projector?

It is far brighter than most projectors and works in a lit room, with no bulb or lamp to replace. A projector can go larger, but it needs a dark room and usually external speakers.

You get the TV, a stand, a remote and power cable. Because of the size, plan for professional delivery and mounting.

Does it support 4K 120 Hz gaming?

Yes, the panel is 120 Hz native and TCL lists Game Accelerator 240 and Auto Game Mode. Note that ALLM and HFR are not listed in the specs.

The only new price we have is $11,999.99 at Best Buy as of November 7, 2026. Large TVs like this usually drop around Black Friday and the Super Bowl.

Can I mount it on a wall?

Yes, it is VESA mount compatible, but at this size use a heavy-duty mount rated well above the TV's weight and a professional installer.
