Experiencing too much lag? Use a faster cable.

A display screen's refresh rate reflects how many times per second the image can be updated. So a display with a 240 Hz refresh rate will refresh the image 240 times per second. The higher the refresh rate the less lag you'll experience and the smoother your connection will be. You'll need the right cable to take advantage of a monitor's maximum refresh rate.

A Thunderbolt cable can support up to 40 GBs per second. USB-C only 10 gbps and HDMI 2.0 18 GBs per second, but HDMI 2.1 48 GBs per second.
