This issue was solved for some monitors using macOS Big Sur 11.2, including the ColorEdge range, which can be connected via USB Type-C / DisplayPort, and Monitors with audio input/output but without HDMI input (such as the FlexScan EV2430).Ī second issue relates to the colour profile created by the system for the monitor, which could be incorrect for M1 Macs.

Eizo, like others, is experiencing an often criticised phenomenon where a YUV limited range signal is transmitted via HDMI instead of an RGB signal – which, according to Eizo, leads to visible banding. The company outlines problems with colour format and colour profiles that have not yet been completely solved. Manufacturer Eizo also discusses compatibility with M1 Macs on its own website. Benq has released new versions of Master Element and Display Pilot palette for M1 Macs. For the models EW2780U, EQ3280U and EX2780Q, the manufacturer has promised new firmware (still to be released), with the PD2720U macOS 11.5 is supposed to solve the problem. Some monitors can only produce 4K at 30Hz. However, reports indicate that this HDMI port can cause problems, so it may be best to control a monitor via USB-C instead.īenq informs very extensively on his website about compatibility with M1 Macs. Only the Mac mini offers an additional HDMI port and can hence control two monitors – one via USB-C and HDMI. However, for MacBook Air and MacBook Pro, only one USB-C or Thunderbolt 3 port is available. You can usually connect a modern monitor via USB-C, HDMI or display port.

Dual monitor set up problemsĪnother problem with M1 Macs is the cables used. However, even HP and Samsung failed to provide any information. Unfortunately not all manufacturers are so proactive and many are not equipped to deal with requests from Mac users – especially manufacturers such as Acer and AOC who tend to design for Windows users. You might assume manufacturers will have listed bugs openly, for example on their support pages.

So here you have to pay attention to the date of a problem report and try to assess the credibility of the author. However, this is not so easy and, following the release of macOS 11.2, many reports are outdated. If you want to find out about the compatibility of a monitor a short search is therefore recommended before buying. This problem mainly affects professional users, for example those who require colour calibration. In some cases it is not even possible use Rosetta to translate the code as it is so deeply built into the system. The main issue being experienced is with the monitor software – they way that the user controls the functions of the monitor.

Outdated monitor software that still needs to be adapted by the manufacturer for the ARM platform.

Errors that a manufacturer must correct via monitor firmware.

Software problems that only Apple can fix.
