I have a ryzen 1700 paired with a gtx 1080 ti so the cpu is a bottleneck for most 1080p games on 1 monitor. I'm planning to get another monitor for triple screen gaming. Will it require more cpu power? From what I know, the cpu calculates stuff thats not on the screen too so if thats true then then cpu performs the same tasks regardless of how many screen or resolution. Is this true? Thanks in advance!
Does the CPU have to do more work for triple screen gaming vs 1 screen?

You kinda are right, but also quite wrong.
On a triple screen display (let's just take it as one huge ultrawide display), you're getting your CPU to display more information, as your CPU would have to pre-render three times the amount of information, and then feed it to your graphics card to render the rest. Think of it like you are running monitors combined into one high resolution monitor. For example, if you have 4 1080p monitors, and you put them in a 2 by 2 format and then put them as one display, you're effectively making a 4K display, as the horizontal resolution is 3840, while the vertical resolution is 2160. This is the same if you put them in a 1 by 4 format, (ultra wide display). If you do the math, you're getting a 7680 by 1080 resolution, which if you multiply them out, gives you the same amount of pixels as 4K. And in 4K displays, you'll see the CPU usage higher than in, say 1440p of course, as your CPU works hard to pre-render those frames. Same for your situation. Your CPU renders more pixels per frame in your triple screen ultra wide display, so it'll work harder.

I thought I was the graphics card that deals with all the renders and displays. 4k gaming have always been bottlenecked by the gpu the cpu still does the same calculations on 1 monitor regardless of resolution right? If you extend that to 3 monitors, shouldn't it work the same way?
