Where did the 5:4 monitors go?

Question

Monitors

I needed a new monitor, and suddenly I was surprised to see that it is almost impossible to find a "square" monitor with an aspect ratio of 5:4. In all stores almost exclusively widescreens are presented, and the most common aspect ratio is 16:9.
What is the reason for such a dominance of widescreen monitors? After all, they are simply terrible in everything except watching a video (and then only with a suitable resolution, and for example, for HD video 1280x720 they are disgusting). Are there any technical limitations to the creation of large 4:3 matrices, or are marketers crap again?

Answer 1

For CRT, there was not much difference in size and resolution. There was a minimum and a maximum in terms of technology.
For LCD, the size of the matrix itself is critical, so it was convenient to standardize the production of TVs and monitors, and 16:9 turned out to be a convenient option, as the standard for HDTV. At this point, 4:3 and 5:4 began to die out, and resolutions close to 16:9 remained.

Answer 2

The 16:9 size has taken root most of all because of the peculiarities of human vision - a person’s eyes are not vertical, but horizontal :) therefore, his visual field is not square, but rectangular :) For two eyes, the horizontal viewing angle is almost 190 degrees.

For example - in front of me now is a NEC MultiSync LCD2690WUXi widescreen monitor. I calmly read the text across the entire monitor ramzer without raising my head (yes, I'm visual, if that's important). If instead of it there was a 5:4 monitor, I would have to either raise my head every time, or move the monitor another half a meter further.
But nevertheless, such monitors are still sold - the query "buy a 5: 4 monitor" gives a lot of results.

Answer 3

Yes, marketers.
Small remnants of square monitors can still be found in the professional segment.
For example, Nec has great monitors 4:3 20-21" 1600*1200 - but unfortunately they cost so much that for that price you can get a widescreen 27" (and not the worst).

Answer 4

Previously, I also used 5: 4 for a long time, but in general this does not make sense, because:
I can’t name any advantages of square monitors, except perhaps a matter of habit. The only plus is that it's cheaper, but if you have very little money for a normal monitor, it's better to take a used one. Widescreen is better for work, better for movies, better for games (or in extreme cases, it doesn’t matter). And the only area where the square rules is web surfing. Just because of this, saving money does not make sense.
It should also be noted that some monitors are able to roll over. With a flick of the wrist, 16:9 turns into 9:16. I have just such a monitor, but I do not use this feature.
