Difference between various refresh rates of display - 240Hz, 144Hz, 120Hz, and 60 Hz.

The difference between different refresh rates is very hard to describe in a picture. For that, you must have to watch the video. In addition, I also explain what to look in the video to identify the difference. In this article, I will show you two videos of bullet and character movement.

Refresh Rate Difference by Character Movement

To identify near to exact difference between two refresh rate displays, you have to record the object's movement with respect to imaginary column. Sounds a bit complex, right? Don't worry. See the following video, in which, the soldier is moving through the door and that was recorded using Sony RX10 II camera, thanks to WASD.ro.

Here, in the above video, consider the columns. Though the columns cannot be used as reference to measure the smoothness. But, for the sake of easy understanding in layman's term, I will tell you the number of columns that the character will travel.

Keep in mind that

  • In low refresh-rate display, the character will travel more columns.
  • In high refresh-rate one, it will travel less columns.

After analyzing the entire video, I found the following results.

Display Refresh RateColumns travelled
60Hz4.5 Columns/sec
120HzAlmost 2 Columns/sec
144HzAlmost 2 Columns/sec
240Hz1-1.5 Columns/sec

I have add here that I couldn't find any noticeable difference between 120Hz and 144Hz displays.

So, based on the above data, it's pretty clear that 240Hz refresh rate display shows a bit more detailed content than 60Hz or 120Hz display.

Now look at the second video below. It will give you a more clear understanding with a bit technical stuff. This second video is also by WASD.ro. In the below video I have explained the movement of bullet (at the end of video) to highlight the difference of refresh rates very deep.

Refresh Rate Difference by Bullet Movement

Here, the movement of bullet was tracked by measuring the distance between two stops.

The results are here.

Display Refresh RateDistance traveled
60Hz1 cm
120Hz0.45cm
144Hz0.45cm
240Hz0.20-0.25cm

So, In 240Hz refresh-rate display, you still won't get a smooth picture when you sit at start to measure it. But, during gaming, its not noticeable.

So, that's the different between 60Hz, 120Hz, 144Hz, and 240Hz refresh-rate displays. If you have option for getting 120Hz panel at low price compared 144Hz panel at little high price, then I recommend going for 120Hz. As I couldn't find the noticeable difference between two closely refreshing displays.
