Apple has officially claimed that the M1 and M2-powered Macs can only support one external display. However, the Mac Mini with M1 can support up to two external displays.
Clearly, the external display support for the latest generation of Macs is kind of limited. Addressing the following problem, Plugable has launched its all-new USB-C or USB 3.0 to Quad HDMI Adapter. This new adapter claims to extend the external display support limitations on Macs.
Plugable has released its USB Type-C or USB 3.0 to Quad HDMI Adapter (USBD-768H4). The brand claims that it can support up to four external monitors via HDMI. Apple M1 and M2-powered Macs are also included in this.
To use the adapter, your device should be running Windows 10 or macOS 11 and above. According to the claim made by the company, it can extend the number of support for the external display on Macs. Their claim goes above what Apple has officially revealed.
According to Plugable’s statement, the adapter can boost M1 and M2 monitor support because it does not rely on Alt Mode. Instead, the adapter makes use of a Silicon Motion chipset, which is well-known for producing NAND flash controllers for SSDs, as well as a software driver.
So this is probably how the adapter is able to increase the number of external display support for Macs.
According to Silicon Motion’s InstantView website, “when a dock is connected every time, it will automatically enable the monitor to display the laptop screen without any user intervention.” Docks from Accell and Wavlink are two other products that employ InstantView.
And don’t expect it to build a pixel paradise full of high-resolution screens. Each of the four monitors connected through HDMI is limited to 1920*1080 resolution at a refresh rate of 60 Hz. Even with all ports enabled, Mac users will be restricted to the number of pixels available on a single 4K panel.
