Which monitor is best for coding and stock exchange?

Question

Monitors

There was such a situation that even more began to work with a computer. It takes 8-10 hours a day, which is a lot by my standards. Decided that it is worth thinking about the monitor.
I identified 2 main problems:

1. Eyes began to get tired, even with rest and looking into the distance
   
2. That about as much time, maybe less later, I will spend at work. What you need to take care of your eyes now.
   

I began to work fully on a laptop (huawei matebook 2020). I don't use the desktop at the moment. I enjoy complete silence. I connected my monitor (HP 22ES) and now my eyes seem to be fucking crazy from the difference in the picture. I don't know, but they got tired more.
Therefore, I highlighted 3 main points when choosing a monitor:

1. The size. Need a 30+ inch monitor.
   
2. Resolution 4k.
   
3. And eye protection. Forgot what it's called. All manufacturers have their own
   

In short, I'm confused about all this. I can not come to the choice of a good monitor. budget 20-30k. It can be more expensive in principle, you can always reconsider spending, but I just don’t see the point in overpaying.
Buying such a monitor, I think that kill two birds with one stone. That there is only one text on the exchange, to put it bluntly, that in coding.

Answer 1

1. Reduce the brightness of the current monitor
2. Buy a good table lamp for the table, which will give a flicker-free (or above 100 hertz) light and equalize the brightness of the monitor with the environment.
3. Set yourself a comfortable font size.
4. Take a break from work, give rest to your eyes, because no, once again, NO monitor with super protection will help you save your eyes at 8-10 hours a day without following the regime.
All other indicators of the monitor - matrix type, diagonal, frequency - are not so critical for LCD monitors and are more for the comfort of working with information. For whom 2 x 24 is suitable, for whom 1x28 .. this is a matter of taste, habit and depending on what to work with.

Answer 2

To start with, go to an ophthalmologist to avoid possible visual impairment. As for the monitor, there are only three main points for constantly working:
1) The correct position of the monitor - the eyes should be at the level of the upper edge, modern manufacturers have completely scored at this point, it is decided by buying a stand that will allow you to lower the monitor to the desired height.
2) It must be flicker-free (flicker-free, etc.) at all brightness levels
3) The pixel size must be average, the BenQ BL3200PT went well for me (it was both smaller and larger, this one is ideal for me) *
Well, *VA matrix is ​​probably more pleasant, if only because of the lack of glow (although in new IPS it seems to be less than before). You can also play around with font smoothing.
* With the change of dpi, as far as I know, everything is still not very good.
