Do you need 144 fps to use 144Hz monitor?

You don't have to hit the full 144fps to utilise the monitors refresh rate though, so long as your fps is above 60 and not fluctuating much you'll be benefiting from it. Nope, it's the same principle as a budget 1080p 60hz monitor, your game can drop to under 60fps and it'll be fine.

What happens when you set the framerate to 144 Hz?

If your framerate is lower, some of the frames will be duplicated, and if your framerate is higher, some of the frames will be dropped. The monitor is always drawing exactly 144 frames every second if it is set to 144 Hz, regardless of the framerate.

Which is the best 2K 144Hz monitor on the market?

The ASUS has a slight edge because it has a better response time and is cheaper. However, if you want native G-SYNC support, the ViewSonic is a very good alternative. The ASUS TUF VG32VQ is the best 2k 144Hz monitor that we've tested available in a 32 inch size.

What kind of cable do I need for 144Hz video?

DVI (Digital Visual Interface) is a more common and widespread connector, but keep in mind that not all DVI versions are the same. Only the Dual-Link DVI-D port can do 1920×1080 at 144Hz or 2560×1440 at 75Hz while the other DVI ports max out at the same bandwidth as VGA.
