2020 MacBook Pro M1 chip

Hey there Jem_name,

Upon researching your question, if you're using the 13-inch Mac, the tech specs link shows that it can only support one external display under the section 'Display Support' here: MacBook Pro (13-inch, M1, 2020) - Technical Specifications

Cheers!

Apple-Silicon 2020 M1 13-in MacBook Pro and Air and 2022 Apple-Silicon M2 13-in MacBook Pro and Air are extremely-capable entry-level computers. They can support the internal display AND an External display up to the previously unheard of size of the Apple 6K display at billions of colors. But only ONE in addition to the internal display.

This may not match the way older computers forced you to work, since older computers were not able to support a really large external display. But it is NOT a defect. The spec was available long before you could purchase the computer.

The Apple standard for its built-in hardware-accelerated displays, makes them suitable for full-motion video for production/display of cinema-quality video with NO dropped frames, and NO dropouts or partial-blank scan lines due to memory under-runs or other issues. This requires a hardware rasterizer/display-generator for each fully-accelerated display.

If you need more hardware-accelerated displays than the built-in and one external display, and an un-accelerated iPad if desired, you probably need a more capable computer.

You're welcome Jem_name,

We're glad we could help! Feel free to reach back out if you have any further questions or issues with an Apple device or service.

Have an excellent day!
