Written by prodigitalweb

If you are a PC user, you may need many monitors to simplify the job. You can extend the display easily, but the video-out port number on your PC can limit the external monitor number. So it is when you need to use an HDMI splitter for dual monitors. You might think is it possible to extend display with it.

You may take the help of a splitter to extend the display to multiple monitors at a time. Hence, the monitors share a similar signal. However, it is vital to note that the monitors can extend the main screen’s display only when the main screen and splitter don’t have any connection to the same video-out port. In this blog article, you can see how to extend the display.

What is an HDMI splitter?

An HDMI Splitter is a device that people use to duplicate a picture. Suppose you are willing to run the same image on two TVs from your cable box. Hence, you should use it. Unfortunately, multiple people think it is a High-Definition Multimedia Interface adapter as they get confused.

Can You Use a Splitter for Dual Monitors?

If you have a PC with only one video-out port, you may need to know if it supports your device. However, PC’s graphics card should be compatible with up to two monitors simultaneously. If you are willing to use two monitors together, insert an extra graphic card.

But if you are not willing to display clear signals, you don’t need to buy it. If you want to display different signals, you need to follow other ways to extend the display. You should ensure that you know correctly about the extension before learning how to extend the display. As soon as you extend the PC’s display, your computer will transfer different signals to those monitors attached to it with the help of HDMI Splitter for Dual Monitors.

All PCs come with video-out ports to which people can connect their extra monitors. For example, if you are using a modern pc, it may have at least one of the following video-out ports:

HDMI: It is compatible with the transmission of high-quality and audio between the monitor & your PC. You can use a DVD player and Blu-ray player as these come with such ports. These help to transmit signals to monitors or HDTV. It supports a 4k display.

DVI: It is possible to extend the display through a DVI port, but it is not compatible with 4K displays.

DisplayPort: It helps extend displays and supports high-quality video transmission. It’s another version, DisplayPort 2.0, compatible with a 16K display.

  1. Display extension using a USB display adapter:

If your PC has only USB Type-C but not others, you will need a USB display adapter. However, you don’t have to purchase an adapter if your monitor supports USB Type-C directly, and it is very uncommon that you come across such monitors.

The input port helps determine the correct type of USB display adapter to use. Usually, with the help of USB Type-C, it is possible to extend the display to other monitors and offer a 4K display quality.

Can You Extend the Display with HDMI Splitter?

Sometimes, you may have to use a monitor for two or more tasks on different screens. In this case, you have to extend the PC display to a second screen. If you need both screens, you have to set them up without using a splitter. But if you want to use over two monitors, use a HDMI Splitter for Dual Monitors.

It enables you to extend the display to more than one external monitor simultaneously. However, you need to know that external monitors will showcase a similar extended display. It is because; the splitter receives an extended display from the PC, and after receiving, it shares the same signal with each external monitor attached to it.

While using a splitter, we advise you to use monitors with equal resolutions. But, first, you may want to know why you must use monitors with similar resolutions. Usually, these devices can not vary the video resolution to all connected monitors. As a result, it has to use a resolution that the minor monitor can display. So, for example, whether you connect a 1080p monitor and a 4k monitor, both of them will get 1080p video quality.

How to Extend Display with HDMI Splitter?

Do you have a laptop or any PC with a built-in display? Then, it depends upon you if you want to extend the PC’s display to external monitors, but only when you have an extra High-Definition Multimedia Interface port available at least. The process needs a few minutes to include additional monitors for PCs.

If you are willing to extend the display with a High-Definition Multimedia Interface splitter, these are the things that you need to follow.

Set up the connection:

You should establish the connection first while the external monitor and PC remain powered off. In this case, your first task is to plug the device into the port on the PC. Next, your job is to connect the external monitors to the ports available on the splitters.

Enable extended display:

As soon as you set up the connection, your task is to enable an extended display on the PC. But, first, you should turn on the PC and go through the steps to turn on the extended mode.

People, who use a Windows PC with Windows 7, 8, or 10 software, have to tap on the “Windows key” and “P” at a time. After pressing, you can see some options popping up on display.

If you are a Mac user, you find the way of enabling extended mode a little bit different compared to a windows PC. Go through these steps if you use a Mac computer. Your PC needs to detect the external monitor automatically once you enable it.

If the pc cannot detect anything, navigate to the Apple menu first. After that, move to System Preferences, and then choose Displays. Next, you should select Arrangement. Next, you can see a few instructions displayed on the PC. Follow these to turn on the extended display.

Adjust Resolution:

If you find the display blurry or stretched on the external monitors, ensure that it is essential to adjust the resolution. You can follow the steps to manage the resolution.

If you are a Windows PC user, you need to move your cursor to a blank space on the PC’s home screen. After that, your job is to tap on the mouse. Now, select “Display settings” from the options you can see on display. Next, tap on the “advanced settings” option. The PC will prompt you to select a display.

Ensure that you have selected the proper display and after that, open the resolution dropdown. You need to increase the resolution or decrease it until the display becomes normal on the external devices. You should save the changes and then test the new resolution with different pictures and texts.

Whether you are a Mac PC user, you should head towards the Apple menu. After that, move to System Preferences and select Displays. Next, tap on the “Option key” and hold it while tapping on Scaled. You can see the available resolutions for the external devices while doing this. Now, your task is to select the resolutions until the external monitors usually display.

What are the most common problems with HDMI Splitter for Dual Monitors?

These are awful as they are incompatible with HDCP (High-Bandwidth Digital Content Protection). An anti-piracy framework is available on Mac PCs, MacBooks, TVs, gaming consoles, etc.

However, the content will not display on your monitor in case a part of your setup isn’t HDCP compliant, but the output is HDCP-protected. In addition, the framework comes with a fallback enabling HDCP-protected content to scale down to a lower resolution.
