Don't modern TV's come with a game mode to reduce this latency (turns off any kinds of image processing)?
I have a 12 year old Samsung LCD monitor that is advertised as 2.5ms

Even then, most VA/IPS/LED displays have something more like 20ms of latency in game mode due to slow LCD refresh rates. Controllers are also randomly delayed by 2.4GHz interference.
This 8bitdo Pro 2 on my desk has 18ms latency all the time. It actually kind of sucks and it's one of the faster wireless controllers.
Edit:// those 8bitdo controllers are pretty terrible looking at that list, Wow.
But there are other sources of latency that stack.
