Apple admitted in a support document published this week that there are currently problems with certain screens on MacBook Pro, MacBook Air and Mac mini with the M1 chip. The company writes that if you connect an ultrawide or super ultrawide display to such a computer, you will not get all of the resolutions supported by the screen. The problem is “known”.

Update announced – check additional resolutions Apple announced that it will fix the bug in a future macOS update. The company did not mention a schedule in its support document. Users could also check whether they can work with the other resolutions offered, which are currently already displayed – these can be seen if you hold the option button in the system settings under screen when you click on “scaled”.

Other display problems Another display problem with external screens that has been available since macOS 11. 1 occurs. Since then, 4K screens from different manufacturers, from LG to Dell and BenQ, can only be operated with a maximum 1080 p resolution on the Mac, including HDR -Support could be lost, as readers report. This also occurs on Intel machines, as well as on M1 Macs.

Suddenly with low resolution The problem seems to be particularly evident on newer devices when the display is controlled via a USB-C port on the Mac. Users of Apple’s MacBook Pro with 16 – inch display report particularly frequently about problems in the operation of external displays, but there the percentage of owners of such screens is likely are also quite high. So far, Apple has not yet commented on this issue; it should be possible to fix it with an update. Interestingly, the LG UltraFine 5K offered by the Mac manufacturer itself works under macOS Big Sur 11. 1 continues to operate normally, users report. (bsc)
