How to Setup Dual Monitors With DisplayPort?


It is no doubt that screen real estate is very important for people nowadays. You might use it for streaming, office work, schoolwork, or anything else that might need switching around applications.

Pressing the alt-tab every single time just adds seconds to your work each time you do it. After all, time is precious and you could prolong your keyboard’s life by two more buttons at a time. Plus, having adapters and other plugs to increase your video ports will add more clutter to your wiring arrangement.

Daisy-chaining is the term used for connecting multiple monitors to single video output, or in other words, multiple monitors from a single device – may be a computer or a surveillance hub.

If your computer has the specs to handle multiple monitors, you’re just a device driver (and another monitor) away from your goals!

How Many Monitors Can You Daisy Chain With DisplayPort?

By standard methods, it would be 4. When your resolution is at 1920×1200 or 1920×1080 (1080p HD), daisy-chaining with DisplayPort will let you connect up to 4 monitors.

4k resolutions will only let you have 1 monitor connected. More unusual resolutions like 1680×1050 will offer you around 5 monitors through this method, however.

In short, it depends on the quality of your display. The higher the resolution, the fewer monitors you can daisy chain with DisplayPort.

This is further determined by your computer specs. If you’re using a PC that has lower specs, especially in the graphics card department; you will find it very laggy when you use multiple monitors.

It is also further determined by your processor and RAM, but what’s most important is the graphics card.

How Do You Set Up A DisplayPort Daisy Chain?

There are 6 steps to complete in order to daisy chain monitors through DisplayPort. When connecting more, you just have to repeat the steps again for the next monitor. Here are the steps:

  1. Check if your PC has a graphics card that supports DisplayPort 1.2 MST. Most modern graphics cards like GeForce GT 1030 support DisplayPort 1.2, but these older ones can only run movies easily and will struggle with gaming. As a cheaper alternative though, Intel’s modern integrated graphics cards support daisy-chaining of up to 3 monitors through this method, but they’re not exactly the fastest.
  1. Turn all monitors on. Of course you need to make sure that all of the monitors you plan on using to daisy chain with are powered. Once they’re all set, be ready for step 2.
  1. Enable DisplayPort 1.2 in your monitor. Don’t forget to do it for each, and make sure that you have all the wires that connect them together ready. In most monitors, this should be located in “Video Settings” where you can locate and enable the “DisplayPort 1.2” option.
  1. Once you have these all set, you should connect your first monitor via DisplayPort to your PC.
  1. Plug the output cable of the monitor into the next monitor, repeat until you’ve connected all the monitors that you need.
  1. Make sure that you disable DisplayPort 1.2 on the last monitor in your connection sequence.

DisplayPort Daisy Chain Adapter

Some monitors may only have one DisplayPort port. This is where DisplayPort daisy chain adapters come to help. With only one male port, the adapter helps split the single port out into two ports, effectively letting you daisy chain monitors even when you only have one port for use in your monitors.

Cheaper adapters and wires, in general, might affect your display’s performance and quality, resulting to very laggy and very blocky display. Thus, consider the quality of the adapter if you want consistent and clear display quality.

This is what a DisplayPort daisy chain adapter looks like. This one uses a DisplayPort input plug as well and uses a USB plug-in in order to give power to the adapter. As some monitors and computers have one DisplayPort at their disposal, we can expand this by adding these adaptors.

The power might get a bit scarcer the more we connect more monitors, though; and we might feel small changes in performance once our hardware cannot handle the display output that we want to achieve.

You Might Ask

Do I need a dedicated graphics card to run multiple displays?

The short answer is no, there are lots of integrated graphics processors that can do the job. However, when you want to achieve higher frame rates and higher display quality, then you might want to try out mid-range graphics cards like GTX 1050Ti. The 1050Ti and similar versions should be able to help you with mid-range gaming with multiple monitors.

Just don’t try to overwork or overheat your PC parts or they might start to malfunction, so overclock and modify at your own risk!

Can I run multiple monitors at 144hz through this method?

Most likely not. Unless you’re planning to have a resolution of 360p per monitor, 144hz is something that cannot be achieved through daisy-chaining. However, if data transfer rates get even more efficient in the future, maybe it will be easier to achieve. Who knows?

Conclusion

If you want to avoid a cluttered setup full of complicated wires and all sorts of adapters laying around, daisy chaining is for you. Due to DisplayPort’s extremely high data transfer rates, it is the best type of port to use in multiple displays.

With a computer powerful enough to handle, having a good DisplayPort setup makes it sure that you lose as little as possible when it comes to quality and performance.

Pushing your display to the limit might pose risks to your hardware, though. If you think that your PC cannot handle display setups or settings in such a way, then avoid doing that setup at all costs.

Some hardware parts are very sensitive and can malfunction when forced to work for more than what it can. This especially applies to older and more outdated parts.
