Just wrote about setting up my new Mac for a new gig: https://thebouv.com/setting-up-my-new-mac.html

That certainly doesn’t answer all our questions. Just the baseline of where I start with a new machine.

I have a KVM that handles four machines with dual monitors: two macs, one proxmox box (or whatever my current homelab experiment is), and my gaming PC:


Keyboard I just have a cheap RedDragon mechanical keyboard for the clickity clacks.

For display port one of my monitors is on a dp to hdmi converter cable. I’ve never looked for a kvm with dp.

Something like this is what you may need.

A KVM with multiple monitor inputs/outputs. You would put your peripherals in the KVM too and just switch with one button.

This is a 4×2 which I think is the best you are really going to get unfortunately, and a bit pricey, though it’s probably worth it if you’ll use it a lot.

The mirror or extend in a function of the computer not the external device.

Are you saying you have use 2 monitors now and you need 2 switch both monitors between all your devices at the same time?

The easy/cheap option is to buy a switch for each monitor. That’s a button switch for each display.

The ultimate single button solution is a 4 x 2 HDMI KVM switch. However the way it works it it will switch both monitors and keyboard control at the same. So if you wanted to do a combo of one desktop display and a Your switch it wouldn’t work.

Depending on your budget and the flexibility you want. What it sounds like you want is a 6×2 Matrix switch. This would allow you to route whatever input to whatever monitor you would like. There are plenty of cheaper options out there but the one I linked is the only one i found that supports 4K at 60hz, not sure if that’s important to you but that’s a spec you should look at. The Switch you have currently only supports 4k at 30hz.

You’ll need several adapters, chief among them a KVM switch. KVM means keyboard, video and mouse. Here’s a model that can handle two monitors and up to four computers:


Not cheap, but there are alternatives that cost several times as much. Your mouse and keyboard plug into this switch, a simple button press switches between devices. No need to unplug and plug in anything once this is set up.

For the Surface, you’ll need a DisplayPort to HDMI adapter and a USB 3.0 hub (for input) with HDMI out. Alternatively, you can get an all-in-one adapter with two HDMI out ports (you may need a USB C to USB 3.0 adapter depending on which Surface Pro you have):
