How to Increase Screen Refresh Rate – (Step-by-Step Guide)

Increasing the refresh rate’s speed means adjusting the number of times per second that a display updates its image. Moreover, a normal stable screen refreshes at a fast enough rate that your eyes can’t catch it.

By increasing the refresh rate, the screen can display motion more smoothly and responsively. To fix monitor flickering, one of the easiest fixes you can try is increasing the screen refreshing rate. 

Increase Screen Refresh Rate To Fix Screen Flickering:

1- First go to the Settings, then select Display.

2- Go to Advanced display, and scroll down to choose a refresh rate option. Increase the refresh rate to 60.06 Hz.  If there are other options, go for higher ones, and wait until the HP monitor flickering on and off stops. 

You can apply some trial and error testing at the refresh rate option. After the first attempt if your screen flickering doesn’t stop, try other ones. 

It is also important to note that many HP monitors have a recommended screen refresh rate Hertz (Hz) setting.

Additionally, you can also check the HP support to see if there is a commended refresh rate for your monitor. Check your monitor model number given behind the screen, then enter it in the search bar for details.

Note: Many HP monitors have recommended screen refresh rates in Hertz (Hz) settings when you go to the screen refresh rate you will find these settings.

Check  Display Cable

Most of the time the display cable causes screen flickering. No matter whatever display port you are using whether it is DisplayPort (DP), HDMI, DVI, or VGA

First of all, check the display cable and look for any visible damage. Look closely, at the heads on both ends of the display cable. Also, check the inner pin connectors. 

In the display cable, you will find various pin connectors, depending on which one you are using. Some of the display ports that you might use are given below.

  • DisplayPort 20-pin connector.
  •  HDMI (standard) 19-pin connector.
  •  DVI (single-link) 18-pin connector.
  •  VGA 15-pin connector.

If the connector pins are damaged, missing, or bent it can cause many issues. So make sure connector pins are accurate, and working properly. Additionally, verify that the display cable connection on both sides is secure. 

Note: If there is any smallest break in connection, then it will cause an interruption in input signals and more. So, push both display cable ends in properly, and firmly. 

Are you stuck in the same scenario even after increasing the screen refresh rate, and carefully inspecting the display cable?

Now time to use a different type of display cable than the one you are already using to fix your HP monitor blinking on and off. If your HP screen flickering stops – the display cable was the issue. Go and get a new display cable.

Some users have reported that this problem happens when their mouse and HDMI display cable are connected to the same USB dongle. 

If you fit in this situation, try to connect your mouse or the display cable directly to your PC, and the other to the dongle. Wait and see if this works for you.

An overloaded power strip could also be the reason, it might not make sense to you. This problem may look difficult, but its solution is quite easy.
