Monitors, matrices and eyes?

So, I am the owner of LG FLATRON W2042T with a TFT TN matrix, bought in ~2009. Usage: some web, layout, coding, movies, internet, etc. I don't play games. I work both in the light and in the dark, with the light of the monitor. From the monitor to the eyes - 65cm.
The main problem: in the late afternoon or after a long work at the PC, the eyes somehow get tired and small elements sometimes look a little “blurred” and whitish. In the morning you get up after sleeping off - everything is again infinitely clear and clear. But in the evening it's like that again ... As if between you and the image there is a small cloud of invisible, but luminous molecules.
A secondary problem: the monitor beeps (PWM, as I understand it) when the brightness parameter is different from 100%, so I, the owner of a rather quiet PC, have to use 100% brightness so as not to irritate the squeak. Everything else is ok.
So, in pursuit of the goal of improving my health, well-being and efficiency, I am thinking about replacing the monitor. So far I'm looking at DELL U2312HM with a TFT IPS matrix.
Questions:
1) Will I get a benefit in terms of comfortable work for the PC from the point of view of the eyes?
2) How optimal is the choice of this particular monitor? For the price, it fits perfectly, the diagonal is also perfect. IPS matrices, as I understand it, are the best in this range? And the firm DELL, as far as I can judge from reading similar topics on Habré, deserves attention?

When choosing a monitor, do a pencil test, your eyes may get tired due to the flickering of the backlight.

There is no IPS on the DELL U2312HM. These are lies. There e-IPS. Such matrices in their characteristics are not much better than matrices of similar cost Tn, which today have become very good.
Yes, IPS and VA matrices have better viewing angles and color reproduction. But this will hardly affect the comfort of work. The only argument is the depth of black.
But cheap IPS and VA matrices (e-IPS, MVA) suffer from a bunch of artifacts, such as uneven backlighting and a crystalline effect, which can be harmful to the eyes.
I myself have a DELL U2412M at home and an expensive monitor on a Tn matrix at work. And I have no reason to believe that I'm less comfortable working behind a working monitor. But the crystalline effect on the home is clearly visible. Subjective feelings are so subjective.
Just spend money on a monitor and choose it carefully - testing it on the spot.
In the price range you have chosen, almost all monitors are very good. There isn't much to choose from. on any matrix. Read reviews.
Much more important for the health of your eyes is the overall ergonomics of your workplace and the way you work at your computer.

So that your eyes do not hurt:
1. The most important thing is to reduce the brightness. The higher the brightness, the higher the strain on the eyes. It is better to set the minimum brightness at which the text is well read.
2. Increase gamma. When increasing the gamma, the image becomes like on a cheap monitor, but such an image is much more pleasant to look at + as a very big bonus, dark shades become much easier to distinguish (in dark photos, pictures, videos, games, etc.).
If, on the contrary, to reduce the gamma, the image will become more beautiful, but less natural, and also a low gamma will increase eye strain, so I advise increasing the gamma. Although it depends on the monitor. On my current monitor, gamma 1.2 is the same as on the old 1.0. Very big difference.
3. Reduce the contrast so that there is no such thing as too white white.
4. Many monitors flicker at low brightness. Do the pencil test and also the camera test. If your monitor does not pass the test, then it is better to buy another one - now Flicker-Free monitors cost the same as flickering monitors, and the Yandex Market even has a Flicker-Free filter.
5. Reduce the blue color to make the image MUCH nicer. Please note that when reducing the blue, you must also reduce the green color. The decrease in green should be 3–3.5 times less than the decrease in blue. For example, if you reduce blue by 6%, then green should be reduced by 1.85%.
I advise all people to reduce blue by at least 3% (and therefore green by 0.92%). The image will become more beautiful at times. Also, thanks to the improvement of colors, you can further reduce the brightness of the monitor, and this will reduce eye strain.
However, you shouldn't get too carried away. Excessive reduction of blue is fraught with the following consequences:
1) White color will become too "burning out". This will increase eye strain.
2) The image will become less natural.
3) Even if at some point in time it seems that the image looks better, in fact it looks worse.
For these reasons, blue reduction should not exceed 12%. This is the limit. As a result, blue should be reduced by a number from 3 to 12%, but I recommend from 6 to 9%.
PS. Don't get carried away with reducing green - the green reduction factor should not be less than 3, otherwise it will lead to burnt white.

In the new year, I switched from a similar, old, small monitor to DELL U2412M - I chose it for a very long time, but in the end I was satisfied with everything :)
Brightness 40%, contrast 75%, 6500K - no annoying deviations were noticed. Although this is all very subjective ...
The case is good, the stand is generally excellent.
Someone else complains about the “crystal effect” ... personally, I don’t notice

It's all very individual. Someone from some monitors gets tired more, someone from others, other things being equal. An important role is played by lighting, the distance to the monitor, the size of the elements on the screen, the position of the head, and so on. I feel uncomfortable behind most LCD monitors, but at home I can sit quietly at my 22 'CRT for almost a day, if necessary.
If you choose monitors and there is an opportunity to take it in the store to “try”, it is better to bring one home (after a thorough inspection in the store, of course) and check it out at home. It is better to make impressions on the 2nd or 3rd day, since on the first day they may turn out to be either too joyful or, conversely, the body will not have time to get used to it and you will feel very uncomfortable by the evening.
Regarding the choice of models, I recommend reading reviews on the same Overclockers:
www.overclockers.ru/reviews/monitor/
I will add that, perhaps, you should pay your attention to Gunnar Optiks glasses already known on Habré, but also about rest for the eyes and Do not forget to warm up for the body either.

www.prad.de/en/monitore/testsoftware/eizo-monitor-test.html download this utility and run it directly in the store on the selected monitor. Many questions will disappear by themselves.
ps: I am writing with U2412M, there is a dependency

Switched from LG Flatron L1953S to LG IPS235T and yes, there is a difference. But I will support klikalka in the idea that everything is individual. I, too, could sit at my first CRT for a very long time.

I work both in the light and in the dark, with the light of the monitor.

And this is in vain. Illumination in the form of a table lamp in the absence of external lighting should be mandatory. Otherwise, a sufficiently large dynamic difference in the illumination of the space around the monitor and the monitor itself is obtained. When working in such conditions, regular eye strain is guaranteed.

Reduce brightness. I chose the BenQ EW2430 monitor on an MVA matrix - I am very pleased. There are two on the table.
Do not work in the dark, even with the lights on, the brightness of the monitor may be much higher than room lighting - you may need to increase the brightness of the chandelier.
Take breaks.
Try special glasses - www.antiochki.ru/ - they still help me. There are prisms such that the eyes look as if into the distance and are less strained when working at a computer.

Maybe not in the topic, but from myself I will advise two options on how to reduce eye fatigue.
1) Install a small utility called f.lux (http://stereopsis.com/flux/ ). At one time, it helped me a lot to overcome the pain in my eyes and the feeling of sand.
2) In autumn, finally, I decided to buy myself such glasses shop.gunnars.com/steelseries-desmo/d/1011_c_200 I am very pleased. They have yellow lenses and they are with a slight plus by default (the doctor said that this is not harmful). A little strange at first, but working in them is much more pleasant.

Maybe I’ll tell a common truth, but if you sit for a day behind any monitor, your eyes will get tired. Then overnight they will recover. You can smooth out the effect a bit with the right lighting. Especially do not sit in the dark in front of the monitor. Personally, it is much more pleasant for me to look at the monitor if the space behind it is lit with an intensity slightly less than the glow of the monitor. In this case, the light source should not shine directly into the eyes. It is ideal to simply illuminate the wall behind the monitor. Well, again, the monitor should not be of very poor quality. I also screw up the brightness of the backlight of the monitor itself (they have gone very bright lately).

Eyes get tired and details look blurry - this is not from the monitor. I recently also had the exact same problem. I endured it for a long time, then I went to the doctor and for diagnostics, they prescribed drops and said to do exercises for the eyes (google some Bates, Avetisov - there are many) two or three times at work. Stop hurting and getting tired. Computer syndrome is not really a joke, after all, IT-shnik needs to take care of his eyes. The doctor said that it does not depend on the monitor, they are all about the same (if it is not completely bad and does not flicker like crt).

I had a similar problem, although I can see everything far and well. I went to the optometrists, at first they didn’t find anything, they praised the “exercises for the tail”, but the problem remained. Then I got a good optometrist, with the right equipment. It turned out - a slight astigmatism, which is compensated by the muscles of the eye in the morning, and in the evening the muscles get tired. So look for the right optometrist with the right equipment.

I want to buy a 24" monitor... I can't find a monitor... I bought ASUS IPS played with brightness, contrast, it just burns my eyes... I bought BenQ TN without a shim, my eyes also hurt... At work I have Philips TN, my eyes don't hurt and shim maximum brightness 0, contrast 50. It's not about shim at all.I tried to set up BenQ TN like on an old Samsung TN... just put it next to it and set it up... On Samsung TN you look like on paper, on BenQ TN you look like on light ... parchment paper through which light beats ... It looks like a different elemental base for the manufacture of matrices ...
