![]() These are a bit expensive, but they’re probably the best solution for most people. So you’ll likely have to turn to a third-party solution, like the Matrox line of dual- and triple-head docks, which use a single video cable to output to multiple monitors. It’s sometimes possible to use two ports at once for multiple external monitors, but this is rare, as manufacturers tend to expect you to use your laptop’s screen and a monitor together. Most laptops only have a single video-out option, with a rare few (like some of Lenovo’s ThinkPad line or older Macbook Pros) offering multiple ports. This will let you easily add an external monitor, but if you want to connect two, things get more complicated. If you have an even slightly older laptop, it probably doesn’t have Thunderbolt/USB-C, instead sporting a VGA, DVI, HDMI, or DisplayPort port. For Most Older Laptops: Get a Display Splitter Box ![]() That may take a while, since some manufacturers ( like Microsoft) seem oddly hesitant to adopt the standard. Once USB-C and Thunderbolt become more common on laptops and monitors, it’ll be the best option around for connecting to just about any kind of video output. Specialized adapters-basically mini-laptop docks-are designed for the purpose of regular docking to a multi-monitor setup with mice, keyboard, and other connections. Thunderbolt has a massive amount of video bandwidth, and it’s more that capable of supporting multiple standard monitors (the new Macbook Pros can output to two 5K displays at once, so long as you have the right adapters). We recommend checking out this Dell Thunderbolt Dock, though there are others out there as well. Note that some laptops, like the small one-port MacBook, do not support running multiple displays from one port using these docks, so check your laptop’s specifications, and if you’re going to try a dock, buy from a store with a good return policy in case it doesn’t work. If your laptop only has one Thunderbolt/USB-C port, you’ll likely need some sort of docking station to connect two monitors to one port.Remember, you’ll need one adapter for each monitor you’re connecting. If you have a laptop with multiple Thunderbolt/USB-C ports but older monitors that don’t have Thunderbolt input, you’ll need some sort of adapter for each monitor, like this USB-C to HDMI or this USB-C to DVI adapter.Unless you have a very new laptop and very new monitors, you’ll probably need a bit more to make this work: You can just hook up each monitor to one Thunderbolt/USB-C port. Please note: this single monitor limitation does not affect Intel-based Macs with Thunderbolt 3, or later M1 models that ship with M1 Max, M1 Pro, or M1 Ultra processors.So, if you have a laptop with Thunderbolt 3 and a Thunderbolt-capable monitor, this is by far the best solution. ![]() One dual monitor example is our DK30CHDDPPD, but please contact support for a recommendation based on your specific setup. One option that allows for more than one external display with an Apple M1 or M2 silicon is to use a USB-C DisplayLink-based docking station or video adapter that requires a driver install. Turning off the laptop display or using clamshell mode does not change this. This is not a limitation of products specifically, and Apple lists support for only one external display in the Tech Specs for Video Support on the M1 MacBook Pro 13”. This limitation also applies to using multiple Thunderbolt or USB Type-C display adapters on both Thunderbolt/USB Type-C ports. Late 2020 models of MacBook Air, MacBook Pro 13-inch, and Mac Mini systems using the original Apple M1 or 2022 models of MacBook Air, and MacBook Pro using the Apple M2 chip support only a single external display over the Thunderbolt 3 ports, even when connected to a Thunderbolt 3 docking station or adapter with more than one video output.
