The recent purchase of an M3 MacBook Pro has led to some confusion regarding its ability to support dual external monitors, especially in clamshell mode. Apple sales representatives have, in some instances, incorrectly stated that the base M3 MacBook Pro supports two external displays, mirroring the capabilities of the M3 MacBook Air. This article clarifies the current situation and what users need to know about connecting multiple monitors to the 2023 M3 MacBook Pro.
Currently, the MacBook Pro models equipped with the base M3 chip do not natively support two external displays simultaneously. This is a key difference compared to the MacBook Air M3, which does support dual monitors when in clamshell mode. If you attempt to connect two external monitors to a base M3 MacBook Pro right now, you will find that it only supports a single external display. This limitation is clearly outlined in Apple’s official technical specifications for the 14-inch MacBook Pro with the M3 chip.
It’s important to distinguish between the different M3 chip variants. While the base M3 chip in the MacBook Pro is limited to a single external display, the M3 Pro and M3 Max chips, also found in higher-end MacBook Pro models, do support multiple external displays. MacBook Pros with the M3 Pro chip can handle up to two external displays, and models with the M3 Max chip can support up to four. The confusion often arises because “M3” is used as a family name for these chips, but their display capabilities differ significantly.
However, there is good news on the horizon. Apple has officially confirmed that a software update is planned for the 14-inch MacBook Pro with the base M3 chip to enable dual external display support in clamshell mode. This update will bring its functionality in line with the M3 MacBook Air. According to reports from 9to5Mac, this update will allow the base M3 MacBook Pro to drive two external displays, just like the M3 MacBook Air currently does. While Apple has not yet announced a specific release date for this software update, it is expected to arrive in the near future.
For users who require dual monitor support immediately with their base M3 MacBook Pro, there are “workaround” solutions available, such as using DisplayLink technology. These solutions often involve software drivers and may come with performance compromises or limitations in display scaling and refresh rates. It’s generally recommended to wait for the official software update from Apple for the best and most seamless dual monitor experience.
In conclusion, if you own a 2023 MacBook Pro with the base M3 chip, be aware that it currently supports only one external monitor. While a software update to enable dual monitor support is expected, it is not yet available. For immediate dual monitor needs, consider alternative solutions with potential drawbacks, or consider if your workflow can accommodate a single external display until the official update is released. Always verify the specific technical specifications of your MacBook Pro model on Apple’s official support pages to avoid confusion regarding display capabilities.
