Oh baby… that’s a monitor I could be really happy with
Maybe instead of having all wireless mechs, you could have a USB hub right under your monitor so you only need to run 6" or shorter cables from keyboard to hub. With some clever cable mgmt, you can have that cable’s route hide around the base of the monitor and run to the computer along the back edge of your desk.
This is what I’d recommend since it’d probably be a bit easier than going all wireless/BT. You can also still use very short, but nicely made braided cables from the community vendors if you want to add that little bit of flair on your desk.
USB hubs are also great if you need to quickly plug a USB thing in without reaching to your computer.
There is an alternative way for bluetooth though if you are really dedicated to go that path. I’ve been exploring this and it works out alright.
Handheld Scientific sells a USB Bluetooth Module for keyboards which acts as both a Bluetooth adapter and a USB to USB bridge. The issue is that there is no power associated with this BT module. This means to use it, your keyboard plugs into this, and this plugs into an external battery; kinda like a battery bank you’d carry around to keep your phone changed. This means that there is still a cable from your keyboard to this dongle, and then this dongle plugs into a battery on your desk. This will give you BT4.0 and should work with any keyboard.
I wish I could give mouse advice, but unfortunately I cannot. I’ve been eyeing the MX master 2, but not sure if it’s light enough.
