Apple Silicon M4/M5 Force Users to Choose Between 4K Resolution and Text Clarity

Apple's M4 and M5 chips introduce a critical regression in 4K external display support, forcing users to choose between full 4K resolution with blurry text or reduced 3360x1890 resolution with sharp text. The limitation is purely software-based—the hardware supports 8K displays—but the GPU driver artificially restricts HiDPI framebuffer allocation, creating a significant usability trade-off for creative professionals and developers. This regression contradicts Apple's positioning as a premium computing platform.
