What is the input lag value of this television?

I bought it months ago. It has a game mode.

Ivh connected my cell phone to the television via wireless, but I thought the input was more blatant than in the dynamic mode

(So the input was in game mode was worse)

But I would like to connect my ps5 qn to the TV. How amazing is the inpu lag? Can you play well online shooters like fortnite (based on the input lag)?

Well, that's a huge difference with wireless cell phones. I also have a television that is significantly older and has no game mode, when I connect a cell phone it has a huge lag, but for a few laps of Fortnite with the switch I don't notice any lag.
