Apple’s next-generation M4 chip was praised for its performance improvements and support for connecting three external monitors simultaneously. However, according to emerging end-user reports, this chip has compatibility issues with some ultra-wide monitors. Here are the details

Mac models with M4 chip struggle with ultra-wide monitors

Devices with the M4 chip (Mac mini, MacBook Pro and iMac) support three external monitors. Two monitors can be operated at 6K resolution and one monitor at 5K resolution. It is also possible to run 8K displays at 60 Hz or 4K displays at 240 Hz. Normally, the chip can work at full resolution with 21:9 ultra-wide monitors with a resolution of 5,120 x 2,160.

However, users report that they cannot activate HiDPI mode (high resolution lossless scaling). According to the feedback, the problem occurs with 5K resolution monitors in 21:9 format, causing users to not get full efficiency from their high-resolution displays.

Normally, this mode allows the display to scale the 3,840 x 1,620 resolution to native resolution, resulting in a sharper image. Interestingly, the same monitors work fine on older Intel or ARM-based Macs. So the problem could be a compatibility issue with the new M4 chip.

In the meantime, some users report that they have been able to fix the problem with third-party apps like BetterDisplay. However, these methods usually limit the frame rate to 60 Hz and compromise image quality. Apple has not yet made an official statement on this issue. The company is expected to fix this issue with software updates, but no exact date has been given.
