Apple’s latest innovation, the M4 chip, brings a new level of performance and versatility to the Mac family. For the first time, it offers the ability to connect up to three external monitors on certain Mac models like the Mac mini, MacBook Pro, and iMac without needing the more expensive Pro or Max chips. This enhancement is a big win for productivity enthusiasts who thrive on multiple displays, as it can support two 6K resolution monitors and one 5K display. Alternatively, the chip can power an 8K screen at 60 Hz or manage a 4K monitor at an impressive 240 Hz.
Yet, while these specs look promising on paper, not all users are enjoying the smooth sailing experience one would expect. Reports have surfaced on platforms like Reddit and the Apple Community Forum about compatibility issues when pairing the M4 chip with ultra-wide monitors, particularly those with a 21:9 aspect ratio and a 5K resolution of 5,120 x 2,160.
These monitors, although operational at their full native resolution, fall short when trying to initiate “HiDPI” mode – a feature that scales down the resolution to 3,840 x 1,620 to enhance image sharpness. Intriguingly, these same setups seem to function seamlessly when linked with older Mac models, whether they use ARM or Intel chips, highlighting a puzzling discrepancy.
People facing these frustrations have found that third-party apps like BetterDisplay offer some relief, though they come with the caveat of restricted frame rates capped at 60 Hz. Currently, Apple has not issued any official clarifications or fixes, leaving M4 users to either wait for a potential update or navigate slightly compromised resolutions with apps such as BetterDisplay, SwitchRes X, or EasyRes.
While it’s uncertain when Apple might address this issue head-on, the workaround solutions in the interim offer an option, albeit with some tradeoffs in frame rate or image quality. These tools provide users with a stopgap measure, ensuring they can still make the most of their impressive setups until a permanent fix is rolled out.
