Best monitor settings?

Question

Monitors

I got used to my monitor for which I worked for a long time. Recently I changed one to two other new ones, and noticed that my eyes became more tired and there was a strong feeling of discomfort.
What brightness / contrast / gamma / temperature settings do you use to work quietly for more than 15 minutes and in general to keep your eyes in order?
Or even such a question - on what basis and with what help do you set up your monitor after purchase?

Answer 1

I leave everything except the brightness at the factory, as a rule. I often set the brightness to a fairly minimum level (but not the most) when working and surfing, when watching movies I twist it by 90%. In games - 100%. Much depends on your personal perception of light, so there are no universal settings - everything is individual. I sit at the monitor for more than 8 hours a day.

Answer 2

I ran into a similar problem and started experimenting with the settings of my monitors, a week later I realized that I was completely unable to set up the monitors so that my eyes did not get tired. I decided to investigate the issue deeper and found that the problem lies beyond simply adjusting the monitor settings:

1. PWM (Pulse Width Modulation, that is, the brightness is adjusted by changing not the brightness, but the operating time of the LED. Simply put, the monitor's LED is forced to blink.) - the most dangerous factor of the monitor, not visible to the naked eye;
   
2. Blue light affects the survival of corneal cells - also dangerous;
   
3. Monitor brightness. The eye accumulates fatigue if you spend many hours in front of the monitor.
   
4. Monitor frame rate.
   

The problem with modern monitors is that these first three factors are interrelated. You can't dim a monitor's brightness without automatically getting a boost in PWM, since PWM is flicker that increases as brightness decreases. You can't remove blue light from a monitor without losing brightness, and therefore automatically increasing PWM. Probably everyone has seen these strange interconnected sliders on the bank's loan calculator, when you increase the repayment period, the amount of payments decreases and vice versa, but another strange factor arises - the percentage of the bank, which is also interconnected with your two sliders. In the situation with the monitor settings, everything is exactly the same. By “pulling” one of the monitor parameters, the entire setup system sets in motion and you get a completely different result than you expected.
How to detect PWM?
On the Internet, I found an interesting way to detect PWM with the naked eye, it’s called “Pencil Test”, if anyone is interested in what it is, please google it, I’ll make a reservation right away that the pencil test didn’t help me, the test didn’t show PWM on my monitor, and my eyes continued to hurt. The understanding came that not only the monitor, but also the lighting in your own room can PWM. Since the issue of health is critical for me, it was decided to purchase a special device ( Luxmeter, pulse meter, brightness meter RADEX LUPIN). Using the device, you can adjust the monitor by catching a balance between these parameters. On the very first day of delivery of my device, I went with it to a store where they sell monitors and started measuring, the consultants in the store looked with surprise, but the security was not called. The results of the measurements were not encouraging, of all the monitors in this store, only one came up to me, I even checked the TVs, there the result was even worse than in the department with monitors. The conclusion is that when you go to the store without knowing the right brand, the necessary monitor options, without a device and trying to buy a monitor to work 98% out of 100% you will buy crap that will ruin your eyesight.
What settings are the least traumatic for the eyes?
The most harmful factor for the eyes is PWM. The lowest PWM on your monitor will be at full brightness and the light theme of the browser and the light theme of the other programs you use most of the time. But the brightness will put pressure on the eyes, you will need glasses, even solar ones will do for the first time, but you should buy special ones, which will be discussed below. Special goggles block harmful blue light. It is worth noting that a bad monitor is difficult to set up in such a way as to eliminate the harmful effect. By the way, for all lovers of the dark theme of the browser and other programs, the dark theme increases the PWM of the monitor. Unless, of course, your monitor looks like it is turned off by the color of the theme, maybe there is no PWM on it, but in all other cases it is there and is quite harmful.
What monitors should be bought for those who spend a lot of time at the computer and do not want to lose their eyesight in 2021?

• The monitor is mandatory with the Flicker-Free option;
  
• Mandatory with the Low Blue option;
  
• The frame rate is at least 120 Hz.
  
• Matrix NT, IPS, VA
  

I do not advise buying a monitor with a diagonal of less than 24 inches, since a small monitor means that you move it closer to see something there and get myopia. For myself, I chose the AOC brand , this manufacturer is good in terms of price-quality ratio. Don't forget to buy safety goggles with at least 60% blue light protection. Many computer glasses with clear lenses provide only 10% protection from blue light. I have two glasses, they are SPG brand and second computer Chinese glasseswith strongly yellow glasses, bought on Aliexpress. SPG goggles are good when you want to see relatively accurate color reproduction, blue light blocking is 60%, but it's hardly noticeable, color reproduction remains satisfactory. Glasses with Aliexpress block the blue color by 95%, that is, the blue color is not visible at all, it partially darkens like ordinary sunglasses, this is great for work and eyes, but sometimes you need to see blue light, for example, when working with design, then it is better to use SPG points. Also, pay attention to breaks when working at the monitor, I work 50 minutes, then do exercises for the eyes for 10 minutes and rest. Install a reminder program on your computer that will keep track of break times.
Thank you for your attention and stay healthy!

Answer 3

If there is no calibrator, then you can set it up using ancient programs like nokia monitor test, NEC Pattern Gen or even web services like this one .
I prefer 6500 temperature, although there are also lovers of 9300.

Answer 4

Behind a computer more than 12 hours a day for a year now. In the dark, the minimum brightness of the screen, in the light of the maximum. Eyes do not get tired, vision is unity.

Answer 5

It depends on what kind of lighting you have, where the monitor is located and on what matrix it is made.
Personally, I prefer to reduce the brightness to a comfortable perception - the eyes themselves will tell you when there is less pressure on them.
Turning the brightness and a bit of contrast makes sense.
What monitors have you been pampered with?

Answer 6

Dell U2410 - brightness: 30, contrast: 38, sharpness: 50. Sometimes I work for 14 hours, with very short breaks, while my eyes do not get tired, rather my back :)

Answer 7

If the question is about color, then on Habré there was a small article on cltest

Answer 8

300ms

Answer 9

max(t)=300ms
