Apple M1 Chip Equipped Mac Computer and EIZO Monitor Compatibility

1. Display Limitations

We found display limitations when using Mac computers with an Apple M1 Chip, which was released in November 2020. Items in section (2) and below may be resolved with system updates. We recommend keeping macOS up to date.
 

Mac Mac computers with Apple M1 chip
OS macOS Big Sur (11.0)
Affected Monitors All monitors, including EIZO monitors


 

(1) Number of Monitors Supported

The Mac only supports one external monitor via Thunderbolt 3 port. Connecting a second monitor to a different Thunderbolt 3 port will only display on one monitor.

(2) Color Format

The signal from the Mac computer changes to YUV Limited Range, which may cause banding. This occurs when using HDMI on a Mac computer with an Intel chipset, or when using HDMI, USB Type-C, or DisplayPort conversion cable on a Mac computer with an M1 Chip.

This issue may be circumvented by changing the Signal Format settings on some ColorEdge monitors as described below.

USB Type-C or DisplayPort Set the value without “YUV” description
HDMI Set the value without “YUV” description
Change the value from “Video” to “PC”

 

 

(3) Color Profile

The color profile automatically created by macOS may be inconsistent with the connected monitor characteristics (e.g. color gamut, gamma). As with the Color Format issue (1.2), this problem can be circumvented on some ColorEdge monitors by changing the Signal Format Settings as described below.

HDMI Set to value not containing “YUV” description
Change the value from “Video” to “PC”

 

 

(4) Portrait Display

The screen resolution is lowered when 90 or 270 degrees of Rotation are selected in the macOS Display menu. Enabling Scaled Resolution in the Display menu does not list the correct resolution on the Display menu. The correct resolution option is listed when selecting “Scaled” while pressing the “Option” key on the keyboard.

 

2. Compatibility with EIZO Monitors

Under evaluation.

 

3. Compatibility of EIZO Software

ColorNavigator and other EIZO software are not yet compatible with models deployed with the Apple M1 Chip running macOS Big Sur (11.0). For the latest information, please refer to macOS Big Sur (11.0) and EIZO Software Compatibility.
