Hi AskBattlestations. First things first--I used to be tech savvy, but I feel like I have been left in the dust the last few years. I am now an idiot and need help. I will be building a new PC soon for personal home use. I want the ability to use it for digital media editing, processing of very large OCR PDF's, streaming/creation (possibly), and daytrading on multiple monitors. I currently have a 2-monitor setup in my home office but may upgrade to 3 monitors. I use a wireless keyboard and mouse with the setup.

I also need to be able to connect my laptop (Lenovo Yoga) via a dock, that can display on the same monitors, and use the same keyboard and mouse.

I am somewhat familiar with KVM's, docks, etc. But my concerns are: (1) will they support 3 displays?; (2) will there be degradation of image quality if everything is ported through a device like a KVM/dock, etc.? (3) What is best/cleanest way to implement this setup?

Laptop will be going back and forth between my home office and work office, so it will be connected and re-connected repeatedly.

Would also love the ability to use PC on one monitor and Laptop on two of them, simultaneously, if possible.

Here is a poorly made diagram of what I'm trying to do: red is the laptop, blue is the PC, and they need to share the green: https://imgur.com/a/3uHDGXr

Thanks!
