Best HDMI Splitters 2026: 4K, 8-Port & Powered Picks

The OREI UHDS-104 is a 1-in-4-out HDMI splitter running HDMI 2.0 at 18 Gbps bandwidth, supporting 4K at 60Hz across all four outputs simultaneously. The critical functional detail: this is a signal duplicator, not a display extender. All four connected displays show identical content from the single input source — there is no way to show different content on different screens. HDCP 2.2 compliance means it handles content protection from Blu-ray players, streaming boxes, and other HDCP-protected sources without blocking the signal. EDID management allows the splitter to communicate the display capabilities of the connected screens back to the source device, preventing resolution mismatches. The metal housing aids heat dissipation during continuous operation. At $33.99, this is the mid-range price point for a 4-port 4K 60Hz splitter that has established a strong track record with 5,343 reviews at a 4.4-star rating. The firm limitation to understand before purchasing: if you want two screens showing different content from one computer, you need an HDMI switch or a GPU with multiple outputs, not a splitter. OREI explicitly states this device will not extend monitors. The maximum cable length of 30 feet per output is a practical constraint for larger installations. For the specific use case of mirroring one source to four displays — conference rooms, digital signage, or multi-TV sports setups — the UHDS-104 handles this reliably at 4K 60Hz.

The OREI 1-in-2-Out HDMI Splitter (UHDS-102) handles the most common splitting scenario — one source to two displays — at $18.99. The same fundamental rule applies as the 4-port model: both connected displays show identical mirrored content from the single HDMI input. HDMI versions 1.3 through 2.0 are all supported, making it backward compatible with older source devices while handling modern 4K sources. The supported audio formats cover LPCM, Dolby-AC3, DTS 7.1, DSD, Dolby TrueHD, and DTS-HD Master Audio — essentially every audio format currently in use. Compatible source devices include Roku, Amazon Fire TV, PS4/PS5, Xbox, Apple TV, cable boxes, Blu-ray players, and computers. At $18.99, the UHDS-102 shares the same OREI build quality and support infrastructure as the 4-port model at a lower price point appropriate for the smaller output count. The UHDS-102 makes the most sense for two-screen setups: connecting a laptop to both a TV and a monitor simultaneously for presentations, or running one cable box signal to TVs in two adjacent rooms. Like the 4-port model, 30-foot cable length is the practical maximum for each output run. For the common two-display mirroring scenario, the UHDS-102 at $18.99 is the cost-effective choice over the 4-port at $33.99 when you only need two outputs.

The HDMI 2.1 Splitter 1-in-4-Out steps up to the HDMI 2.1 specification with support for 8K at 60Hz, 4K at 120Hz (and 144Hz), 1080p at 240Hz, and Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) — the features that modern gaming displays and TVs use for adaptive sync and instant response switching. HDR10, Dolby Vision, and HDCP 2.3 are all supported. The 22 EDID management modes via a 5-position toggle switch provide more granular compatibility control than standard plug-and-play splitters. This is the right splitter if you have a gaming PC or PS5 capable of 4K at 120Hz or 1080p at 240Hz and want to output to multiple displays simultaneously with those high refresh rates intact. Standard HDMI 2.0 splitters like the OREI models cap at 4K 60Hz, which is insufficient for high-refresh gaming scenarios where the source and displays support higher rates. The significant caveat: with only 7 customer reviews at the time of writing, this is a newer, less-tested product compared to the OREI models with thousands of reviews. HDMI 2.1 splitters are technically more complex than 2.0 models, and limited review data means limited field experience with edge cases and compatibility issues. At $44.99, it also costs more than the 4-port OREI despite having fewer confirmed real-world installations. For production environments or critical installations, the OREI models have the reliability track record. For early adopters with HDMI 2.1 sources who specifically need high-refresh split output, this is currently the most capable option on the page.
