A panel that drops to a lower mode is usually limited by the cable or the input. The R21,699 mini can usually drive more than a bundled lead allows. Check the active refresh in the display settings first, because that separates a cable fault from a setting.
A panel that quietly drops to a lower resolution or refresh rate is usually limited by the cable or the input chosen, not by the machine driving it. Checking the active setting in Displays separates a cable fault from a simple setting in seconds.
Check the active resolution and refresh rate in System Settings, under Displays, before assuming the machine cannot drive the panel properly. A R21,699 compact desktop can usually drive more than a bundled cable allows, so the cable is the first thing worth replacing with one rated for the full specification.
Open Displays and confirm whether the resolution reads 3840x2160 or drops to something lower, since macOS sometimes defaults to a conservative setting on first connection rather than the panel's true maximum. Setting it manually often solves the problem outright with no hardware changes at all.
A cable not rated for the resolution and refresh rate you want will silently cap the connection at a lower setting rather than failing outright, which is exactly why it goes unnoticed. Check the current cable range for one properly rated for your panel's full specification before assuming the machine itself is the limit.
Some monitors only reach 120Hz or 144Hz over one specific port and quietly cap at 60Hz on another, so check the panel's own manual rather than assuming every input behaves identically.
Work through it in order across roughly 5 minutes: confirm the setting in Displays first, since that alone fixes a surprising number of cases with zero cost. Swap the cable second, testing with one you know is properly rated if you have one on hand. Only after both of those come up clean is it worth suspecting the monitor's own port or the machine itself, and even then, testing the same cable and setting on a different device first narrows it down further before any hardware ever gets blamed unfairly for a simple cable fault.
Rarely; the cable or the active setting in Displays is the far more common cause of a panel running below its true maximum.
macOS sometimes chooses a conservative default on first connection; setting the refresh rate manually in Displays usually fixes it.
Yes, an unrated cable often passes a lower refresh rate cleanly and only fails once a higher one is requested.
Yes, checking Displays before blaming the cable, and the cable before blaming the port, holds across the wider mini PC range as well.

Windows transparency effects can be switched off to make supported backgrounds more opaque. Use Accessibility, Visual effects or the colour settings, then compare a menu against your wallpaper. This R0 preference changes appearance; it is not a promised.
Windows title bar window shake can minimise other open windows when you shake the active window by its title bar. Inspect the Multitasking setting and switch it off if that gesture interrupts your work. The preference costs R0 and does not require new hardware.
Windows Print Screen opens Snipping Tool when its keyboard preference is enabled. Change the option under Accessibility, Keyboard to choose another workflow. Test whether you need a clipboard image or a saved file.
Windows desktop icons missing may be a visibility setting. Right-click the desktop, choose View and inspect Show desktop icons. If only system icons are absent, use Desktop icon settings. Check the Desktop folder before assuming files were deleted.
