Monitor flickering problem – change refresh rate

A flickering monitor is not only unpleasant to work with but it is dangerous for your health. It may causes headache, eye problems, even can provoke migraines.

Monitor flicker may affects users in the autism spectrum, including people with Asperger ‘s Syndrome. 

The problem with monitor flickering is caused of low refresh rate. It is measured in Mhz. Refresh rate has to be >75Hz.

Refresh rate depends also of screen resolution – the bigger screen resolution is – the higher refresh rate is neeed.


To change refreshrate, rightckick on empty point on your Desktop.

Then select the last menu option – Properties.

The ‘Display Properties’ window is opened:

display settings advanced

display settings advanced

Select Settings tab and click on Advanced button.

A new window pops up:

plug-and-play refresh-rate

plug-and-play refresh-rate

Here choose Monitor tab and from dropdown menu select the biggest refresh rate.

Click OK. Your refresh rate is changed.


And one more thing to try to improve performance:

Repeat steps above but instead of ‘Monitor’ tab, select Troubleshoot tab.

plug-and-play troubleshoot

plug-and-play troubleshoot

Move Hardware acceleration slider to the left and click OK.


Hello world!

As this is my first post, I want to begin with something funny.

I am in 9th class.

We have computing and ICT classes 4 times a week.

As sometimes they are booring, me and my friends love to play tricks with the teacher.

Here are some of recent jokes we ‘invented’:

  • swapping mouse with keyboard inputs and reporting a problem with them.
  • swapping mouse left/right buttons
  • setting mouse speed to max so it is impossible to open anything by click
  • before leaving, decrease monitor brightness so it becomes black and seems not working
  • make a screenshot of the desktop and set it as wallpaper. Then hide the real icons  and look someone trying to click on the wallpaper’s icons.
  • lock the keyboard with Functional keys.

Those are light jokes. We never intend to destroy something.

I respect my teacher and appreciate her sence of humor 🙂
