Final note: to make my little experiment work, make sure that the vertical size of the papers (height/vertical length) is the same in all aspect ratios, in order to be fair. Like make them all 9 cms or 9 inches for ease of measure (21cm*9cm, 12cn*9cm is 4:3 etc).
If you wish to fill your vision in the horizontal axis first, and see the difference in the vertical axis of your field of vision, then

you (quite obviously) need to make them the papers the same size in the horizontal length, but this requires some mathematics to calculate. like make them all 16 cm in length (16cm*9cm, 16cm*12cm for 4:3, 16cm*6.9cm for -21:9). What you ll see then is that the more square aspect ratios have extra info on top and bottom of your vision that you can't see cause of your nose and forehead xD

Another important factor is the game's Field of View settings, as well as your distance from the screen and the screen's size, from which you can calculate your real-distance field of view, which you should make sure that it is close to the game's fov for best experience. But I won't talk about this now.
Some nice links about stuff I presented:

and that's how you 'lose' lots of time in Wikipedia by learning a lot from it :D

and by the way, besides the 3440 x 1440 resolution, there are also some cheap 2560 x 1080 pixel sceens out there, mostly by LG, for about -$200, which is kind of cool, but I'd like to see lower prices.

hahaha yes, I 've been rank 5 for so long , don't even know if i can increase my character cap / rank more at this point, but still I added a ton of information, even a phone, to get more points and to increase my limit xD

But the accuracy of colour reproduction on those medical monitors is unreal.

so is their price xD

The numbers do have meaning, but only in context with the rest of the specs of the device in question. I've seen 720p TV's that look fantastic, and 1080p screens that look like VHS playback in comparison.

In a way you're right, the ads are geared towards simple consumers, but they're also vastly over-simplified which leads to people blindly going along with it, which results in people who know next to nothing about the tech they interact with daily.

Haha I hear you buddy I almost went 2560x1440 but man that widescreen just makes me tingle. Now that 3440x1440 are becoming more common i must buy one!

it is, and much cheaper alternative to 3440*1440 :)

1680*1050 is pretty awesome too, please don't go and buy a 1080p, you won't see the difference (unless you go for an expensive one with 120+hz frequency and great viewing angles and color reproduction, maybe an IPS one or something)

Generalissimo is right. Get a 144Hz/120Hz monitor if you play FPSs, or if not, maybe a widescreen 2560x1080, or a 1440p monitor. 1080p is not enough by itself to warrant an upgrade.
