What are refresh rates for TVs, anyway? Do you really need 144Hz or 165Hz, or is 60Hz good enough? Here's what you need to know.

While the refresh rates of PC monitors keep going up, TVs remain stagnant. Maybe it’s time for that to change.

That means a monitor with a refresh rate of 60Hz updates its image 60 times per second, while one with a 144Hz refresh rate updates its image 144 times, and so on.
