What is a Dual DisplayPort and how does it work?
A Dual DisplayPort is a feature on modern graphics cards that allows two independent display signals to be sent over a single cable. This is achieved through a technology called Multi-Stream Transport (MST), which enables multiple monitors to be connected to a single DisplayPort output. The graphics card is able to send two separate display signals, each with its own resolution, refresh rate, and content, over a single cable.
The Dual DisplayPort technology uses a DisplayPort version 1.2 or higher connection, which has a bandwidth of up to 17.28 Gbps. This allows for the transmission of two high-resolution signals simultaneously, such as two 4K monitors at 60Hz or one 4K monitor at 120Hz and one QHD monitor at 144Hz. The MST technology also enables the daisy-chaining of monitors, allowing multiple monitors to be connected to a single DisplayPort output.
Can I use two DisplayPorts simultaneously on my laptop?
The answer depends on your laptop’s specifications and capabilities. Not all laptops have Dual DisplayPort capabilities, even if they have multiple DisplayPort outputs.
