A few weeks back I decided to go ‘cheap’ and got an HDMI switcher and a couple of Amazon basic HDMI cables. The intention was to create a good enough solution for switching my screen between my new Mac and work laptop. Needless to say, it did not go well, and I ended up having to scrap the solution for what I knew was the superior (but pricer) option to begin with (a KVM USB-C switcher). Reminded of the old adage:

A poor man can afford only the very best.
