Question

What is 90hz 60z and 120hz refresh rate?

pls tell the answer​

Answer 1

Answer:

Measured in Hertz (Hz), the refresh rate counts the number of times the display refreshes every second it is on. A 60Hz display refreshes 60 times per second, 90Hz is 90 times per second, and 120Hz is 120 times per second. So a 120Hz display refreshes twice as fast as a 60Hz panel, and 4x faster than an old 30Hz TV.

Answer 2

Answer:

Similarly, a 90Hz display refreshes 90 times per second while a 120Hz display refreshes 120 times per second.
