Searching for the best viewing experience? Are you one of those that love using several monitors at once? Then you’ve reached your destination. 

From DisplayPort 1.2, DisplayPort 1.4, HDMI, Mini DisplayPort to Thunderbolt 3, in this product guide, we reviewed the best DisplayPort splitters in the market so that you will be satisfied with the final decision.

What is a DisplayPort Splitter?

A DisplayPort splitter is a special adapter that gives you the facility to take video signals going to one monitor and split it into two or more signals for other monitors to use. 

The associated monitors can all display the same information simultaneously or expand it as if they were each part of a single screen.

How many monitors can DisplayPort support?

Your laptops’ or notebooks’ GPU (Graphics Processing Unit) generally have a limitation in how many monitors they can drive, usually between 3 and 5.

Also, DisplayPort 1.2 has a limitation on how many pixels it can send down the pipe from one monitor to another. DisplayPort 1.2 bandwidth limits indicate that the following display resolution should support the specified maximum number of monitors.

  • 1680 x 1050 = 5 monitors
  • 1920 x 1080 (or 1920 x 1200) = 4 monitors
  • 2560 x 1600 = 2 monitors
  • 3840 x 2160 (or 4096 x 2160) = 1 monitor

Thus, DisplayPort offers you one more excuse not to buy a desktop.

Is DisplayPort faster than HDMI?

If you want to connect your computer to a TV, your first option should be HDMI. A lot of TVs and computer monitors have HDMI. It’s popular and easy to use. However, for really high resolutions, speed and frame rates, DisplayPort is definitely better. Especially for laptop-to-monitor connections.

For instance, HDMI 1.4 can handle up to 4K at 24Hz, but DisplayPort 1.2 can easily handle 4K at 60Hz. DisplayPort 2.0 goes up to 16K at 60Hz.

Not even the more recent versions of HDMI could match the efficiency of current DisplayPort capabilities. Here are the best choices of DisplayPort splitters we have selected after a critical review.

3. Fosmon 2-Port HDMI Splitter Hub – Best HDMI splitter & switch

Best HDMI splitter & switch

Fosmon 2-Port HDMI Splitter Hub

The Fosmon 2-port HDMI splitter hub is a cheap and effective bi-directional signal splitter and switcher that is very useful in a number of scenarios.

As a splitter, it takes one signal and splits it between two separate display devices. 

For instance, you may have two television sets in a retail shop, and you want to show the same advertising display in the two screens at the same time, then you would need this splitter which has one input and two outputs.

However, as a switcher, it takes two signals from different channels or devices and switches them to one output screen. 

For instance, you may have one television, and you want to be able to switch the display between your DVD player and your laptop without disconnecting the HDMI cable connected to the DVD player and inserting it in the laptop. 

You would need this kind of switch as each device would have its own HDMI cable and it is easy to switch between them.

  • No power source is required
  • Dual LED display for status
  • Latest HDMI standard of 2.0
  • It does not have any DisplayPort 
  • It cannot extend the display, it can only mirror it.

StarTech 3-Port Mini

The 3-Port Multi-Monitor Adapter allows you to connect one mDP 1.2 port to three independent DP MST ports for an extended display of your computer activities.

The fact is that newer generations of laptops are getting more and more portable. Thus, fewer video outputs and smaller integrated screens have become common. This is where the mDP to 3 DP comes in.

The three displays connected would be able to handle 1080p at 60Hz or two 4K at 30Hz, all going through an mDP port in a laptop or notebook running Windows without video compression. With macOS you can only use this adapter for screen mirroring.

This adapter would greatly increase your productivity at work, as you would be able to add two or three screens to your workstation.
