When a second monitor is connected, macOS may only allow mirroring, or one of the monitors may fail to display properly.<h3 id="q-which-macbook-models-support-three-external-monitors-in-abcd-mode">Q: Which MacBook models support three external monitors in ABCD mode?</h3>A: Only MacBook Pro models with Max chips, such as M2 Max, M3 Max, and M4 Max, can support three external monitors in extended mode.<h3 id="q-can-a-dock-or-hub-enable-abc-mode-on-a-macbook-that-only-supports-one-monitor">Q: Can a dock or hub enable ABC mode on a MacBook that only supports one monitor?</h3>A: No. If the chip itself only supports one external display, such as on base M1 or M2 models, a dock cannot enable additional monitors in native extended mode. Third-party adapters or DisplayLink software can simulate multiple displays, but image quality and performance may be limited.<h3 id="q-whydo-some-older-intel-macbooks-support-two-external-monitors-while-others-only-support-one">Q: Why&#xA0;do some older Intel MacBooks support two external monitors while others only support one?</h3>A: This is due to graphics hardware. The 15-inch and 16-inch Intel MacBook Pro models with dedicated GPUs can drive two external displays, while the 13-inch Intel models with only integrated graphics are limited to one.<h3 id="q-can-a-macbook-pro-with-a-max-chip-use-the-built-in-display-along-with-four-external-monitors">Q: Can a MacBook Pro with a Max chip use the built-in display along with four external monitors?</h3>A: Yes. A MacBook Pro with a Max chip can run up to four external monitors in addition to the built-in display, for a total of five active screens.<h3 id="q-if-my-monitor-supports-144hz-can-my-macbook-achieve-the-full-refresh-rate">Q: If my monitor supports 144Hz, can my MacBook achieve the full refresh rate?</h3>A: It depends on the chip. Some newer models, such as those with M4 and M4 Max, support 4K at 144Hz. However, most MacBook models are limited to 60Hz on external monitors.<h3 id="q-does-closing-the-macbook-lid-affect-external-monitor-support-in-extended-mode">Q: Does closing the MacBook lid affect external monitor support in extended mode?</h3>A: Only the base M3 MacBook models behave differently. With the lid open, they support one external monitor. With the lid closed, they can support two external monitors. Other models are not affected by whether the lid is open or closed.<h3 id="q-can-i-disable-the-built-in-display-and-use-only-external-monitors">Q: Can I disable the built-in display and use only external monitors?</h3>A: Yes. This is called Clamshell Mode, which allows the MacBook to operate solely with external monitors when the lid is closed.<h3 id="q-if-two-monitors-are-connected-but-show-the-same-content-how-can-i-enable-extended-mode">Q: If two monitors are connected but show the same content, how can I enable extended mode?</h3>A: Go to System Settings &gt; Displays and select &quot;Extend Display&quot; instead of &quot;Mirror Display.&quot;

Due to version limitations, Switch 2 may not be able to connect directly to portable monitors via a USB-C cable. To address this issue, we have updated the firmware for certain portable monitors, enabling them to work properly with a direct USB-C connection. If Switch 2 receives future system updates, we will also update the software accordingly.The SOP (Standard Operating Procedure) for most monitor upgrade software is generally similar; the main difference lies in the firmware being loaded (please pay special attention to Step 4 for details). Here, we will use the GR19BU software upgrade SOP as an example.
