Just after some suggestions for a wireless keyboard/mouse combo.

Putting up a wallboard in the office and just need a half-good solution for the keyboard/mouse. Only talking maybe 5m in terms of long range. But the current cheapies I've tried seems very hit and miss over just a couple metres.

RDP/any other remote desk isn't really an option as it's full 8K resolution. Super hard to deal with on the 1080p monitors at my desk.
