Do I Need 2 HDMI Ports For Dual Monitor Setup?


Splitting a screen on a single monitor is helpful; you can have a variety of work tackled side by side; meanwhile, having a complete screen for one purpose and the other full screen for the connected task would make the job super easier. Even if you are working, gaming, or anything, dual screens will work wonders in easing the job.

A study has been conducted about the comparisons between single and dual monitors, which resulted in fewer mouse clicks and lesser window switching has been recorded when using dual monitors, of course, remembering the increase in working capacity.

Just another study confirmed that People using dual monitors reported lower causeless cognitive load than people using a single monitor.

If your work involves multiple windows or running the application simultaneously with dual screens, the tasks quickly come in handy. Windows now make it relatively easier to connect more monitors. 


However, when it comes to the need for two HDMI ports or you can have a monitor with 2 HDMI ports to have a dual monitor setup, you can even manage it with a single HDMI port but with an HDMI splitter or an adaptor. One of the critical preconditions of a dual monitor setup is to ensure your PC has the correct outputs; this includes at least two HDMI outputs or a minimum of one HDMI port with an additional display port output available. However, laptops or PCs with GPU (Graphic processing unit) have the capacity of four possible connections. 

How To Connect Dual Monitor Setup

 Things you required for the setup would be:

  • Connections and Cables

Check if the HDMI ports are available on your monitors; if not, source the appropriate cables and use adaptors or splitters if needed. Now with the help of the wires, insert one end of the line into one monitor’s port and the other end into the other monitor’s port. 


  • Displays and Settings 

Now locate your display; after attaching the dual monitors, you need to configure them. These settings could be advanced or basic; windows are proficient at automatically managing setup. The first screen-detected would be considered the primary screen; the other would be regarded as the secondary display. You can now set the resolutions according to your wishes.

After locating your display, you need to arrange your displays under the settings as extended display to have shows going on simultaneously, playing different applications. Even so, you can also duplicate the displays. You would also get an option of changing the title of primary and secondary shows; if you want to switch your primary monitor to the secondary one, you can do it easily through settings. 

Once all the cables have been aligned, and the monitors have been configured, you can easily sit back and enjoy the free extra space. The only tricky part was figuring out the correct cables.

However, while connecting the second monitor, you may need an adapter cable from Displayport to an HDMI port. What needs to be kept in mind is that this process is uni-directional. The information only flows from the Display port connected to the GPU end; to the HDMI back connected to the display. Therefore, this process only happens when you do not have another HDMI port available; using a Displayport is another way. If you have two HDMI ports available, all you have to do is connect the cables to the HDMI ports and enjoy the dual monitor setup.

When Would you Need Two HDMI ports?

Having two HDMI ports would help you transfer audio and videos to your secondary display to enjoy your screening on an enormous screen, maximize your entertainment and multitask like a pro.


Is There A Difference Between HDMI 1 and HDMI 2?

Both the ports can deliver up to 4K video; however, the excessive bandwidth allows HDMI 2.0 to provide 18 – 48Gbps, whereas HDMI 1.4 Can transfer up to only 10.2Gbps. This wasn’t even considered necessary a few years before, though.

How Does HDMI Splitter Works For Dual Monitors

The HDMI splitter usually works as a duplicator, as the whole point of the splitter is to duplicate your screen to the other monitor. For example, if your PC or Laptop is connected to two dual monitors with a splitter, it will show the same duplicated image on all three screens. You might not be able to extend the screens; however, you need an adapter instead of a splitter to have an extended display. An HDMI adaptor would provide you with the dual monitor setup by extending your screens to two different monitors. 


Advantages Of HDMI Cables

HDMI is considered the fastest transferring data cable, as it allows the signals to be transmitted up to around 48Gpbs it provides high-definition videos and sound. This quality even makes it the best choice for gaming as well. Not only Xbox or PlayStation, but HDMI is now often used in home theaters to let everyone enjoy a superior quality of music.
