Key Points

HDMI has quickly become the preferred signal format for high-quality audio and video. Today, most audio-visual devices, including TVs, home theater systems, soundbars, gaming consoles, laptops, set-top boxes, and projectors, have at least one HDMI port.
For most people, their devices have enough HDMI ports to meet their needs. However, there are instances where you might need more HDMI ports than your devices have. An example is when you want to transmit the same signal to multiple TVs. In such cases, an HDMI splitter comes in handy.
An HDMI splitter is a device that splits one input signal into several output signals. The device has one HDMI input port which takes a signal from one source, such as a set-top box, duplicates it, and sends it to several audio or video devices via multiple HDMI output ports.
After reviewing a number of options, we identified the five best HDMI splitters you can buy today:
- #1 Best Overall: OREI UltraHD 4K 1×4 HDMI Splitter
- Best Budget: NewBEP HDMI Splitter 1×2
- Best 4-Out: Keliiyo HDMI Splitter 1 In 4 Out
- Best Multipurpose: GANA Aluminum Bidirectional HDMI Switcher

#1 Best Overall HDMI Splitter: OREI UltraHD 4K 1×4 HDMI Splitter
- 18Gbps powered HDMI splitter
- 1 HDMI input and 4 HDMI outputs
- Supports DTS 7.1, Dolby TrueHD, and DTS-HD Master Audio
- With EDID management
- Does not extend monitors
The OREI UltraHD 4K 1×4 HDMI Splitter tops our list of the best HDMI splitters, as it checked most of the items on our checklist. The first thing you notice is its wonderfully designed, slender, and compact body that is smaller than similar products from its competitors. That means it can blend in with other appliances or be stashed away from lines of sight. The device also has a metal casing that makes it durable. The metal casing also helps keep it cool because of the metal’s high heat conduction and dissipation properties.
Most HDMI splitters have two output ports, meaning you cannot duplicate signals to more than two devices. The OREI 1×4 addresses this challenge by providing four HDMI outputs, more than enough to meet most people’s needs. This HDMI splitter also has an in-built amplifier, meaning it boosts signals after splitting to prevent signal integrity loss.
The OREI 1×4 is compatible with High-Bandwidth Digital Protection (HDCP 2.2), a feature found in most TVs and set-top boxes. The HDCP 2.2 detects and blocks pirated content. This splitter also comes with an Extended Display Identification Data (EDID) management system that allows all devices connected to the splitter to communicate what audio and video formats they support.
The OREI 1×4 supports several audio formats, including DTS 7.1, Dolby TrueHD, and DTS-HD Master Audio. Unfortunately, it does not support Dolby Atmos, which might disappoint some consumers. It also does not extend computer monitors. Regarding resolution, this HDMI splitter supports 480p, 720p, 1080p, 2K, and 4K display resolutions at 60Hz frame rates.
The OREI HDMI splitter uses a micro USB power cable and a wall adapter. These are included in the packaging box and have a one-year warranty.

- Compatible with various signal sources and displays such as computers, Apple TV, Xbox 360, PS3 and PS4, Chromecast, and others
- USB cable included
The NewBEP HDMI Splitter 1×2 costs less than $10, making it the best budget option. Despite being cheaper than most devices on this list, the NewBEP has decent specifications. It is a passive splitter that duplicates signals and transmits them to two devices without latency or deterioration in audio and video quality.
The NewBEP is also compatible with numerous devices, including computer monitors, gaming consoles like the Xbox 360 and PS4, DVD players, and high-definition TVs. In addition, the device supports a range of video resolutions, including 480i, 480p, 576p, 720p, 1080p, and 4K. These features qualify the NewBEP 1×2 as one of the best HDMI splitters you can buy today, especially considering its price.
Furthermore, the device supports decent cable lengths of up to 50ft. Unfortunately, it supports HDMI 1.4, an older version than the more recent 2.2. The HDCP support is also dated, as the NewBEP is only compatible with version 1.4.

Best 4-Out HDMI Splitter: Keliiyo HDMI Splitter 1 In 4 Out
- 1 input to 4 outputs
- Includes AC adaptor
- HDCP V1.4
- Supports full HD 1080p, 3D, up to 4K@30Hz
- Cannot extend monitors
Get the Keliiyo HDMI Splitter 1 In 4 Out if you want a device that offers multiple output connections. An HDMI splitter with two or three output ports is not guaranteed to meet your needs. We recommend playing it safe and buying a splitter with at least four output ports. The Keliiyo is an active HDMI splitter ideal for casual users who want to share a signal with multiple devices without fearing you will run out of ports.
The device can pass through resolutions as low as 480i and 480p and as high as 4K. However, 4K pass-through is only at 30Hz frequency. It also only supports HDMI 1.4 and it cannot extend monitors. However, it has a sturdy metallic body that guarantees longevity. Moreover, the input and output ports contain anti-oxidation and anti-corrosion properties to prevent rusting that can interfere with signal transmissions.
| Pros | Cons |
|---|---|
| There are four output ports. | 4K pass-through is limited to 30Hz frequency. |
| The splitter allows the pass-through of high-resolution signals. | It supports the older HDMI 1.4. |

- 3.4Gbps data transmission
- One input and two outputs
- Uses standard HDMI 2.0 Cable
The GANA Aluminum Bidirectional HDMI Switcher is the best multipurpose option because it acts as a splitter and a switch. The device has three HDMI ports.

The GANA has a button in the middle to alternate between the splitter and switcher modes. The button is paired with two LED indicators numbered one and two to show the activated mode. Regarding compatibility, this multipurpose HDMI splitter supports 4K video at a 60Hz frequency and is backward compatible with lower resolutions like 2K and 1080p.

How to Pick the Best HDMI Splitter: Step by Step
There are at least tens if not hundreds of HDMI splitter manufacturers. However, not all make high-quality, reliable, and durable products. Below is a checklist you can use to shop for the best HDMI splitters.
- Inputs and outputs
- Resolution
- Cord length
- Compatibility
Inputs and Outputs
Most HDMI splitters have one input port. However, the number of output ports is what matters most. The number of output ports determines how many times you can duplicate an audio-visual signal. This determines how many devices you can connect to one splitter. The number of inputs and outputs is denoted using numerals. For example, 1×2 means the device has one input port and two output ports.
Resolution
The HDMI splitter you choose should transmit video at the same quality as the source. For example, if you have a TV with 4K resolution, the splitter should have a 4K pass-through. Also, note that when connecting multiple monitors, the splitter will transmit video using the resolution of the lowest-rated monitor. That means if you have a 4K and 1080p monitor, the splitter will pass through the video at 1080p.
Cord Length
Always confirm that your preferred HDMI splitter’s cord length is enough to meet your needs. Cord length is important as it determines where you can position different devices. For example, sports bar owners should look for HDMI splitters with long cables that allow them to place TVs in strategic positions.
Compatibility
Ensure the splitter you buy supports the same HDMI version as your devices. The same applies to specifications like audio and video formats and HDCP. Otherwise, you risk buying an incompatible HDMI splitter, which is a waste of money.
What to Know Before Buying an HDMI Splitter
Many people cannot differentiate between an HDMI splitter and an HDMI switch. A splitter duplicates one signal into multiple signals that can be transmitted on several devices. Conversely, an HDMI switch takes multiple signals and passes them through one cable that connects to your TV or other devices.
You can buy a powered (active) or non-powered (passive) HDMI splitter. Passive HDMI splitters do not require power. However, you may experience a drop in signal quality. On the other hand, active HDMI splitters connect to a power source using an adapter. Most have an in-built amplifier to boost signal output, nullifying possible signal dropoff.
Using an HDMI Splitter: What It’s Like
Using an HDMI Splitter is all about convenience. It allows you to distribute an HDMI signal to multiple devices, which saves you money. For example, you do not need to buy another cable box to enjoy content on more than one TV. It also improves home aesthetics by reducing the number and length of exposed cables.
