Can I combine Studio Display and iMac into one display?

Is it possible to use a StudioDisplay with 2020, 27" iMac and have both displays be one wide display not two seperate displays?


Retina 5K, 27-inch, 2020 iMac and Apple Studio Display, 2022. I would like them to function as one wide 5120 x 1440 display rather than two 2560 x 1440 displays.

What you describe is extended desktop options instead of mirroring.

Says:

"Details:*This model can simultaneously support the

internal display at full native resolution and up to one 6016x3384 (6K)

external display at 60 Hz with support for 1 billion colors; one

5120x2880 (5K) external display at 60 Hz with support for 1 billion

colors; two 3840x2160 (4K UHD) external displays at 60 Hz with support

for 1 billion colors; or two 4096x2304 (4K) external displays at 60 Hz

with support for millions of colors. It supports both extended desktop

(second workspace) and video mirroring (internal display duplicated on

the external display) modes."


So if this is your Mac, you need to make sure you are using a thunderbolt cable to ensure full capability.


USB-C cables may not support the resolutions you desire.
