Well, at least because in digital everything is relative and has different digital characteristics: someone has more megapixels, more memory, a faster processor, a better monitor. And if we have already talked about the monitor settings (we highly recommend reading this article before reading the one that you now see on the screen), then we have not yet reached the choice of a monitor. In any case, we will assume that you know that the monitor is your eyes in the digital world, just eyes with certain characteristics, depending on its setting, you will see images better or worse.
However, do not forget that your own eyes (not the monitor) have the ability to adjust automatically, adapt to any situation of ambient lighting. Naturally, in the dark they will not show you saturated colors, but they will not let you fall into the pit. That is why, after setting up the monitor according to our scheme, at first it seems that everything becomes dark and faded, but after a while you begin to see pictures like you have never seen before.
However, sometimes your own eye becomes so demanding that it already rests on the technical limitations of the monitor itself, which sometimes simply cannot be adjusted even to 32 levels of brightness, which, theoretically, it should distinguish), not to mention finding the same differences in different channels (here, my monitor does not want to distinguish between several rectangles in the blue line, although it sees the rest well). At such a moment, the decision to change the information output device comes to mind – after all, if your money, even small ones, partly depends on it, you should think about pumping it.
We will not discuss whether you need a new monitor or whether you can get by with the old one, this is not our business – we will just try to help with the choice. In the meantime, read the article about setting up the old (and any) one more time.
