Apple M1 Chip Equipped Mac Computer and 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 (11.2) |
| Affected Monitors | All monitors, including other company's 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.

| Gradation Display | |
Update: This issue was solved for some monitors using macOS Big Sur 11.2 or later as described below.
- Monitors without audio input/output, such as ColorEdge, connected via USB Type-C / DisplayPort.
- Monitors with audio input/output but without HDMI input. (e.g. FlexScan EV2430)
This banding issue still remains with HDMI connection even if using macOS Big Sur 11.2 or later.
This issue can be circumvented by changing the Signal Format settings on some ColorEdge monitors as described below.
| HDMI |
Set the value without “YUV” description |
|---|
(3) Color Profile
The color profile automatically created by macOS may be inconsistent with the connected monitor characteristics (e.g. color gamut, gamma).
Update: This is solved for monitors with the same conditions listed under (2) Color Format issue. The color gamut issue was solved with the other monitors on macOS Big Sur 11.2 or later, but the gamma issue still remains.

(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.
