M4 Mac owners experiencing issues with ultrawide 5K monitors

A number of M4 Mac owners are experiencing issues with their 5K ultrawide monitors not displaying the correct resolution. The issue lies in macOS' high-pixel density mode (HiDPI) not working correctly on these devices, leading to displays appearing blurry or too small to read. The problem seems to be most prevalent among users of the M4 Mac mini and M4 MacBook Pro. Some have found success using the third-party utility BetterDisplay to fix the issue, while others still experience blurry text.
