Question about LG OLED65G42LW

Is it also 144 hz or why does it say 120 hz?

Yes, the "OLED65G42LW OLED evo Gallery Edition" TV is equipped with the new Alpha 11 AI Processor. This processor brings improved performance in image processing, graphics and speed and supports AI-based image enhancements and a higher refresh rate of up to 144Hz, among other things.

What are the differences between this TV, the Gallery Edition, and a standard LG G4?
Additionally, does this model come with a stand, or would I need to purchase one separately?

Thanks for the tip, I have just reported the error. The panel can reach up to 144 Hz.

Why does it say 42 and not 48 or 49 - this is the first time I've seen this and it's cheaper than the other G4 televisions?
