Anyone else use a 2nd vertically mounted monitor along with your 43" main?

[djxput]

I dont know much about this and previously posted a thread with no responses - so trying this title instead.

I dont know what size I should look at I'm thinking a 27" since I see most monitor's width is approx 62 63 cm and the height of my 43" is is 59~ cm. I'm thinking ips 1440p would be good?

any opinions on the matter and what monitor exactly?

I'd like to hook up a 2nd monitor that I use along with my 43" to use for websites and whatnot while I use my main for other work.
