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?
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.
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.

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.
