We know it only too well, the Apple ecosystem is a closed vacuum, from which little can escape. Connecting with third-party devices is difficult, although Apple has been forced to make efforts in recent years to simplify it. The problem seems bigger than ever when it comes toconnections between monitors and the latest Macs, equipped with Apple's M4 chip.
Many user stories claim that their computer is unable to display proper resolution on their 5K UltraWide monitor. According to Apple's forum, the problem specifically affects people who have screens with a resolution of 5120 pixels by 2160 pixels. If this is your case, then yourMac M4may have resolution issues on the screen.
Mac mini M4s affected first?
According to information from 9to5Mac on this subject, it would be above all the Mac mini M4s which would be affected by this resolution problem. To display their content on an external monitor, they use the so-called high pixel density protocol (HiDPI), and it is this that is faulty.
At the moment we do not know exactly what the reasons for this bug are or if Apple will be able to correct it with a simple software update. It can in fact be a bad line of code in macOS or a hardware defect physically present into the M4 chip.
In both cases,Apple should be able to resolve this issue with a patch, but you will probably have to wait several more weeks. If you are affected by this problem, the best thing to do is to go to a lower resolution, 3840×1620 seems to work very well. In a few weeks, when Apple has fixed this defect, it will then be possible to use your monitor to its full potential again.
