The best HDMI splitter for gaming is one that is rated for the exact resolution and refresh rate your console or PC outputs, so a true HDMI 2.1 splitter suits 4K 120 Hz setups, an HDMI 2.0 splitter suits 4K 60 Hz, and a capture card with pass-through is the better answer if your real goal is streaming or recording. Most disappointing splitter experiences come from buying a model rated below what the source sends, so the specification matters more than the brand.
First, decide what you need to split
“Splitter” is used loosely, and the right device depends on the job.
- One source to two displays: a splitter. One console or PC feeds a monitor and a TV, or a monitor and a capture device.
- Two sources to one display: a switch, not a splitter. Using a splitter in reverse does not work.
- One source to a monitor plus recording: a capture card with HDMI pass-through is usually better, because it handles the signal timing and avoids extra latency from a chain of devices.
- Extending a PC desktop to a second display: use a second graphics output or a display adapter, not a splitter, because a splitter mirrors the same image.
What matters for gaming
- Bandwidth rating: HDMI 2.0 splitters are listed for 4K at 60 Hz. HDMI 2.1 devices are the ones listed for 4K at 120 Hz or 8K. A splitter cannot pass more than its chip supports.
- HDR and colour: check that the product supports HDR10 and the chroma format you use. Some cheaper units pass HDR but drop to lower chroma modes.
- VRR and ALLM: variable refresh rate and auto low-latency mode may not pass through a splitter. HDMI 2.1 models sometimes list VRR support. Do not assume it.
- EDID handling: a splitter has to present one display’s capabilities to the source. If it chooses the lower-capability display, the source may drop to a lower mode. Splitters with EDID mode controls or a DIP switch let you choose.
- HDCP: protected content such as some streaming apps and console menus can blank out when two displays have different HDCP levels. Capture cards typically cannot record HDCP-protected content.
- Cabling: use certified cables at the rated length, especially for HDMI 2.1 bandwidth.

HDMI 2.1 splitters for 4K 120 Hz
For a PlayStation 5, Xbox Series X or a PC with a modern graphics card feeding a 4K 120 Hz display, look for a splitter that explicitly states 4K at 120 Hz on its product page. These are less common than HDMI 2.0 models and usually sit in the mid-range tier. Read the fine print: some listings claim HDMI 2.1 but only support a subset of features, and the HDMI Forum’s naming rules mean “HDMI 2.1” on a box does not guarantee 48 Gbps bandwidth. Look for a stated bandwidth, a stated 4K 120 Hz mode and reviewer confirmation.
The second display matters. If one output goes to a 4K 120 Hz monitor and the other to a 1080p capture device, the splitter has to choose a mode for the source. Models with EDID controls let you copy the more capable display, or force a lowest-common mode.
HDMI 2.0 splitters for 4K 60 Hz and 1080p
If your source runs at 4K 60 Hz or 1080p 120 Hz, an HDMI 2.0 splitter is enough and sits in the budget tier. These are the common 1×2 units from brands such as OREI, Portta and J-Tech Digital. They are well suited to a Nintendo Switch dock sending video to a monitor and a capture card, a PS4 Pro or older Xbox, or a streaming box feeding two TVs. Check HDR10 support if your display uses it, and check that the unit powers from its own adapter rather than USB bus power.
Capture cards with pass-through
If you want to stream or record, a capture card with pass-through does the job a splitter would, with fewer unknowns. Elgato lists the HD60 X as supporting pass-through with HDR10 and VRR, with recording at a lower resolution than the pass-through. The Elgato 4K X targets high-refresh 4K pass-through for HDMI 2.1 sources and captures at 4K at a lower refresh rate than its pass-through. AVerMedia and others offer similar cards. The practical limits are the USB bandwidth needed on the PC and the difference between what the card passes to your monitor and what it captures.
Pass-through delays are a concern for competitive play. Reviewers report that good cards add negligible delay on the pass-through path, but that is a point to confirm for the exact model before you rely on it.
Latency and signal quality
A splitter is a passive-seeming box, but it has an active chip that processes the signal. Manufacturers typically state low latency but rarely publish a figure, so there is little to compare. A better approach is to choose a unit with the correct rated bandwidth, keep cables short and certified, and avoid chaining splitters. If you notice flicker, sparkles or dropouts, a cable or bandwidth mismatch is the most common reason.
Compatibility and fit notes
- Power: most 4K splitters need an external power adapter. Buy a unit with a power supply included or a cable that matches.
- Ports: a 1×2 splitter has one input and two outputs. A 1×4 splitter works the same way with four outputs and more signal loss.
- Cables: HDMI 2.1 signals need certified Ultra High Speed cables on every link.
- Consoles: PS5 and Xbox Series X can output 4K 120 Hz and VRR, which are the features most likely to be lost through a splitter.
- PC graphics cards: a splitter mirrors the same signal to both outputs. It does not give you extra desktop space.
- Dolby Vision and VRR: only some products pass them. If you need them, look for the product page to mention them.
Pick X if…
| Your situation | Pick |
|---|---|
| 4K 120 Hz console to a TV and a second display | An HDMI 2.1 splitter with a stated 4K 120 Hz mode and EDID options |
| 4K 60 Hz console and a second display | An HDMI 2.0 1×2 splitter |
| Streaming or recording as well as playing | Elgato HD60 X or a similar capture card with pass-through |
| 4K 120 Hz play with recording | Elgato 4K X or similar, premium tier |
| Several consoles to one TV | An HDMI switch, not a splitter |
| Extra desktop space | A second display output on the GPU |
Budget tiers
Budget: HDMI 2.0 1×2 splitters for 4K 60 Hz, suitable for older consoles and basic mirroring. Mid-range: HDMI 2.1 splitters and entry capture cards. Premium: 4K 120 Hz capture cards with pass-through and a strong software package.
Alternatives
If you only need to feed a monitor and a speaker or headset, use an HDMI audio extractor or the console’s audio output. If you want to play on a TV and record, a capture card is simpler. If you want a second PC input, use a switch. For a single high-end monitor that you also want on a TV, the cleanest route is usually a second video output from the graphics card.
Frequently Asked Questions
Does an HDMI splitter add input lag?
A good splitter adds very little, but manufacturers seldom publish a figure. For competitive play, pick a model with a clear 4K 120 Hz rating and test it in your own setup, or use a capture card whose pass-through path is well documented.
Can I use a splitter to run a second monitor with different content?
No. A splitter duplicates the same signal to every output. To show different content on each display, connect each display to a separate graphics output.
Will an HDMI splitter work with 4K 120 Hz and VRR?
Only if it is HDMI 2.1 and lists 4K 120 Hz and VRR support. Many splitters pass the signal but drop VRR. Read the product page and reviewer notes for the mode you use.
Why does my screen go black through a splitter?
Common causes are an uncertified cable, mismatched HDCP levels, an EDID conflict between displays or a unit without enough power. Try shorter cables, a different output order and the unit’s own power adapter.
Do I need a splitter or a capture card for streaming?
A capture card with pass-through is better for streaming because it gives your PC a capturable video signal. A plain splitter sends one output to a display and another to a capture device, which works but adds more points of failure.
Can I record protected content with a splitter?
Usually not. HDCP-protected content is blocked on capture devices. Some splitters strip HDCP, which may breach the terms of a service, so use them only where permitted.
