Too much brightness and contrast on your monitor is an issue for your eyes and that’s why your monitor should have an ideal value for these parameters. But what is an ideal value and how to know that for your computer? To get the answer for this question, we will go thru a simple test on your monitor and will identify the ideal value.
Increase the contrast of your monitor a medium value, say 60 – 70 % and then by keeping a distance of your eyes and monitor around 1 meter. Now check whether any distortion or extreme sharpness happens to images or other stuff on screen. If so, then adjust the value accordingly. Now you are having an optimized value of contrast on your monitor, we will move to brightness test.
Before changing the brightness of your monitor, take a look at the image attached below and see if you can see 21 different shades in the picture (Last shade is pure white, so you can count one as that).
If you are not able to distinguish between the later shades then adjust the brightness on your monitor to do that. Now we will go thru the extreme test where you will be able to adjust the brightness of your monitor by more accurate value.
Here in extreme test, you have to distinguish the extreme black and extreme white shades provided below. Try to get the 5% and 95% shade as different than 0% and 100% shade.
If you are able to differentiate and visualize the extreme shades then you are ready with the ideal value of brightness and contrast on your monitor. Healthy eyes can work more than the painful one so keep track of your health and keep your eyes clean and cool by adjusting monitor contrast and brightness.
Latest monitors comes with preset values like “Cool”, “Sports”, “Standard” etc. Try to set the preset value as Cool if it is OK otherwise perform the above test to get exclusive value on your monitor for your eyes.
