Is the TCL Q5CF good for gaming?

Yes. It has a 144Hz native panel, Game Accelerator 288 and up to 288 VRR, which suits PS5, Xbox Series X and PC gaming. Input lag is low in game mode.

Does it have local dimming?

No. The Q5CF uses a high-brightness edge-lit backlight without local dimming, so contrast relies on the HVA panel. Dark scenes will not match mini-LED sets.

What smart platform does it use?

It runs Fire TV, not Google TV. That means the Fire TV interface, Alexa voice control and the included voice remote, with apps like Netflix, Prime Video and Disney+.

How big is the TV and what mount do I need?

The set is about 94.3 inches wide, so measure your wall and viewing distance first. Use a heavy-duty mount rated well above the TV's weight, and plan for two or more people to lift it.

Is it worth choosing over a smaller OLED?

If size and brightness in a large room matter most, the 98-inch QLED wins. A smaller OLED gives deeper blacks and wider viewing angles but a much smaller picture.
