Which monitor to get for iMac 21.5?

Question

Monitors

I have an iMac 21.5'' 2013 with an integrated Intel Iris Pro 1536 MB graphics card. The resolution is 1920 x 1080. I want to buy two additional monitors for it. Is it worth taking monitors with a larger diagonal and resolution, how convenient will it be to work with such a system, and will the integrated video card pull two additional monitors? The iMac has dimensions of 528 x 175 x 450 mm, I looked at the Yandex market that with approximately similar dimensions you can take a 27 '' monitor. I want the monitors to be the same height and look organic.
I don't need professional color reproduction, I just write code, read articles on the Internet and watch movies. For the price, I want some inexpensive model up to 10000-15000.
PS If I was not clear - I want to take 2 identical monitors.

Answer 1

Resolution 1920 x 1080

Is this the resolution of the current screen? (a rhetorical question and with a hint)
Take those monitors that you like in appearance, in terms of picture quality, in terms of the convenience of the stand, in terms of the thickness of the frame ... The resolution will be secondary, you can hardly find less than the current one anyway.
A two-dimensional picture creates almost no load. But with the support of two additional ones at once, that is, only three monitors - you need to look at the characteristics of your piece of iron. Well... call yabble and ask :D

Answer 2

You have this Iris Pro 5200 video card, if so, then it should support two monitors with a resolution of 2560x1600 via Thunderbolt.
