Is the LG M3 worth it over a regular OLED?

The M3's main extra is the wireless Zero Connect box, which keeps cables off the screen. If you do not need that, a wired LG OLED like the C series usually costs less for similar picture quality.

How does the wireless connection work?

A separate box holds your HDMI and antenna sources and sends the signal wirelessly to the screen. The screen still needs a power cable, and the box needs power and a clear line of sight.

How many HDMI ports does it have?

Three HDMI ports, all on the Zero Connect box rather than the screen. That is fewer than many 77-inch TVs, so plan for a soundbar or switcher if you have several devices.

Is it good for gaming?

Yes. The 120 Hz panel and OLED response suit consoles, and game mode keeps input lag low. Check that your console and soundbar fit the three HDMI inputs.
