Thanks for the tip! The Corsair display does look pretty nice, but it’s far too expensive for what it actually offers. I also noticed that Corsair has a keyboard with a built-in Stream Deck and display, which would be a neat solution - but I don’t really want to have to look that far down at my keyboard.
In the meantime, I found out that the Lian Li display can be used without that rather odd software suite. So I’ll probably get an AIDA64 Extreme licence instead and build my own custom sensor panel. Since the display connects via USB directly to the motherboard, there should be little to no performance impact.
