Best HDMI Splitter for Dual Monitors – Overview
Many people use a dual monitor setup for work, personal, and other computer-related activities. But, to be honest, it’s a bit hard to get many things done on just one monitor.
This is why so many companies have adopted two monitors instead of one.
And with the massive technological strides, using dual monitors is one of the most productive ways to get your work done.
One common misconception is that an HDMI splitter is a good way to implement a dual monitor setup for extending different displays. However, an HDMI splitter is designed to duplicate the same display across multiple screens, not extend different displays across them. For extending different displays, an HDMI switch or a graphics card with multiple outputs is typically used.
These devices take input from one source and duplicate the signal to several outputs, not creating multiple sources but mirroring one source across multiple displays.
So this nifty device will make it happen whether you want to have a dual monitor setup to enhance your workflow or run a smart TV box signal to several TVs.
To lessen the confusion, this review will explain the difference between HDMI splitters, switches, and adapters.
More importantly, we will look at the best HDMI splitters you can find out there for your dual monitor setup.
What’s The Difference Between an HDMI Splitter, HDMI Adapter, and HDMI Switch?
HDMI Splitter
An HDMI splitter duplicates video and audio output from desktops, laptops, projectors, TVs, gaming consoles, etc.
HDMI Adapter
An HDMI adapter typically converts one type of video connector into another, such as HDMI to DVI or vice versa. It doesn’t inherently extend or duplicate video output across multiple displays; those functions depend on the capabilities of the source device and the display setup.
HDMI Switch
An HDMI switch is a device that connects several devices to one HDMI port. This device is handy if you don’t have multiple HDMI ports on a TV, soundbar, etc.
An HDMI switch allows you to switch between various HDMI inputs and view what you want.
For instance, if you have a smart TV box and a gaming console connected to an HDMI switch, you can instantly switch from the TV box to the gaming console.
What are the Common Problems with HDMI Splitters?
The compatibility with HDCP varies by model and manufacturer, with some splitters supporting HDCP to ensure the protected content is securely transmitted.
HDCP is an anti-piracy framework built into devices such as Mac PCs, MacBooks, TVs, gaming consoles, etc.
Once HDCP confirms that a connection has been made, it will encrypt the signal to prevent the unlawful recording of the content.
If the output is HDCP-protected, but one part of your setup isn’t HDCP compliant, then the content won’t show up on your monitors.
However, HDCP has a fallback that allows HDCP-protected content to scale down to a lower resolution, 720p, if the setup isn’t HDCP-compliant.
Some cheap HDMI splitters bypass HDCP protocols by accident because their manufacturers don’t bother acquiring an HDCP license.
Some of the Top HDMI Splitters for a Dual Monitor Setup Include:
1. OREI 4K HDMI Splitter 1 in 2
Best HDMI Splitter for Dual Monitors – OREI 4K HDMI Splitter 1 in 2
OREI has three HDMI splitter versions. The one mentioned here lets you output to two devices, such as monitors, but you can find four and eight output versions.
However, it’s always good to have extra output ports in case you need them in the future.
However, one feature that sets this HDMI splitter from the competition is that it can bypass HDCP-protected content.
Another essential feature of this splitter by OREI is that it comes with a power adapter, so you don’t need a dedicated cable to power it up.
However, note that this splitter doesn’t support HDCP 2.0 and HDCP 2.2.
While some splitters support downscaling, they automatically adjust the output resolution to match the capabilities of the connected displays if supported by the device. This ensures compatibility but doesn’t individually tailor resolutions per display in a dual setup; both screens will display the lowest joint resolution supported by both
It works best with HDMI cables up to 30 feet long. OREI also says that this splitter has a one-year warranty with support.
I use OREI to connect my laptop to my two Samsung monitors. It is a docking station, and I have never had a problem with it.
