Comprehensive Guide to DisplayPort Daisy-Chain Multi-Monitor Setup
Using DisplayPort to daisy-chain multiple monitors for creating a cinema-like large display in a room or office is an incredibly interesting and appealing option. While the basic idea is simple—just connect multiple monitors using DisplayPort cables—the actual process is not as straightforward as it seems. This practical guide will give you a brief overview of all the options for adding multiple screens. You'll learn about popular graphics cards (and their models) that support multi-monitor functionality via DisplayPort. Additionally, you'll discover how to extend, mirror, and duplicate displays using Miracast and Airplay. Let's start by discussing the fundamentals of DisplayPort daisy-chaining.
Four Essential Requirements for Connecting Multiple Monitors via DisplayPort
1. DisplayPort 1.2 or Higher
Your monitors must support at least DisplayPort 1.2. Previous versions, such as DP 1.0 and 1.1, do not support Multi-Stream Transport (MST), which is a crucial component for daisy-chaining.
DisplayPort 1.3 and 1.4 are even better options. These versions offer higher bandwidth, enabling support for higher resolutions and refresh rates.
But what if your graphics card doesn't have a DisplayPort?
2. Graphics Cards with DisplayPort
Graphics cards provide two interesting ways to set up multiple monitors using DisplayPort:
Graphics cards without MST but with multiple DisplayPorts: Some graphics cards lack MST functionality but come with multiple DisplayPort outputs. You can connect each DisplayPort output on the graphics card to the corresponding input on each monitor using separate cables. This method allows you to duplicate, mirror, or extend the screen across multiple monitors.
However, this approach has its drawbacks. You'll end up with a tangle of cables around your desk, which can cause clutter and create a stressful work environment due to potential cable conflicts. Moreover, the number of monitors you can connect is limited to the number of ports on your graphics card.
List of well-known graphics cards that support multi-monitor setups via DisplayPort (without MST):
AMD Radeon RX 580
NVIDIA GeForce GTX 1650, RTX 3060 Ti, 3070, 3080, 3090
AMD FirePro 2270, V7900
Graphics cards with DisplayPort (MST): These graphics cards claim to support daisy-chaining via DisplayPort. To set it up, connect one end of a DisplayPort cable to the DP-Out port on your PC and the other end to the DP-In port on the first monitor. Then, insert another DP cable into the DP-Out port of the same monitor. Repeat this process to create a daisy-chain connection of multiple monitors using DisplayPort.
Popular graphics cards that enable proper daisy-chaining of multiple monitors:
AMD Radeon RX 6900 XT, 6800 XT, 6800
NVIDIA GeForce RTX 3090, 3080, 3070, 3060 Ti
AMD Radeon Pro W6800, W6600
AMD Radeon Pro WX series (e.g., WX 8200, WX 7100)
NVIDIA Quadro RTX 8000, 6000, 5000
3. High-Quality DisplayPort Cables
It's crucial to use high-quality DisplayPort cables. By high-quality, I mean cables with aluminum connector housings (for better heat dissipation) and sturdy teeth (to grip the monitor and computer ports firmly). In short, the cables should have a good reputation. Click the link below to check out cables recommended by a well-known and trusted institution in the United States.

4. Enabling MST on Monitors (for some models)
Access the On-Screen Display (OSD) menu on each monitor and ensure that MST or the daisy-chain function is enabled. This setting allows the monitor to receive and transmit video signals correctly.
Navigate to Display Settings > DisplayPort > Enable Connection.
Can I Daisy-Chain to DisplayPort via USB-C?
Not all monitors support daisy-chaining using USB-C. While some monitors are equipped with USB-C ports that provide power and data transfer capabilities, only a few support daisy-chaining. This feature is available on certain Dell monitors, which support USB-C to USB-C daisy-chaining.
Dell, a giant in the monitor industry, states that it does not support daisy-chaining when it comes to devices with different specifications, such as cables, adapters, or converters. This includes combinations like USB-C to DisplayPort, USB-C to HDMI, DisplayPort to HDMI, and similar setups. However, the overall possibility of achieving daisy-chaining remains zero in these cases. If you have a Windows laptop and a USB-C hub with a DP port, you may have a chance to experience MST functionality, depending on the DP port on the USB-C hub. Make sure it can support a resolution of 4K at 60Hz so that you can connect three monitors using the MST feature.
Nevertheless, this limitation does not apply to advanced USB4 and Thunderbolt 4 connections. These connections offer the highest bandwidth available among any cable standards, equivalent to the capabilities of HDMI 2.1.
Recent demonstrations have shown that USB4 and Thunderbolt 4 cables can handle data rates of up to 80 Gbps. Therefore, these technological advancements hold great promise for enabling daisy-chaining of high-resolution and high-refresh-rate monitors using USB-C interfaces in the near future.
Conclusion and Reminders
By connecting monitors, you can create a larger and more engaging workspace or entertainment environment. However, there are a few things to keep in mind. Ensure that your monitors support DisplayPort 1.2 or higher, choose graphics cards that offer multi-monitor functionality via DisplayPort, use high-quality DisplayPort cables, and enable MST on your monitors.
Although daisy-chaining can be convenient, it's important to note that as the number of monitors increases, video quality may be affected due to shared bandwidth. You may also be curious about Thunderbolt daisy-chaining and want to learn tips for multi-monitor connections on Mac devices.
