Because the unit relies on external 5V 1A power to drive the active signal amplification, connecting the included USB cable to a dedicated wall block prevents signal flickering, screen blackouts, and handshake errors that can occur on lower-voltage USB ports.
Frequently Asked Questions
Do all HDMI splitters support 4K gaming at 120Hz?
No, many splitters on the market only support HDMI 2.0 standards capped at 4K at 60Hz or 4K at 30Hz. True 4K 120Hz passthrough requires full HDMI 2.1 bandwidth, which reaches up to 48Gbps. When shopping for hardware in 2026, verify that the unit explicitly lists support for 4K@120Hz, variable refresh rate (VRR), and auto low latency mode (ALLM).
Why does an HDMI splitter mirror the same picture instead of extending desktop screens?
Standard HDMI splitters are engineered solely to duplicate a single video stream across two separate screens. Operating systems treat a splitter output as one destination, so you cannot get independent desktop workspaces. If you want separate displays for multitasking, an active multi-stream transport hub or dedicated GPU outputs are required.
Can you pass Dolby Atmos audio through an HDMI splitter?
Yes, but only if the splitter features dedicated audio passthrough and your connected soundbar supports the incoming audio format. Many basic splitters lack eARC support, which can downgrade high-bitrate surround sound to stereo. To understand advanced spatial audio routing, check our guide on how to turn on Dolby Atmos on a TV properly.
Does cable length affect video quality when using Best 4k Tvs With Hdmi 2 1 gear?
Yes, long HDMI runs often degrade ultra-high-speed signals and cause intermittent screen flickering. Ultra High Speed HDMI cables operating at 4K 120Hz or 8K 60Hz generally perform best when kept under 10 to 16 feet. Using thicker 26 AWG or 30 AWG certified cables ensures stable data transmission and preserves HDR color accuracy.
Will an HDMI switch increase input lag during competitive console gaming?
No, quality passive and powered HDMI switches introduce negligible latency that will not affect gameplay. Because the switch acts as a direct physical relay for the digital signal, input lag remains well under one millisecond. Gamers pairing current-generation consoles with best 4k tvs with hdmi 2 1 setups can switch between systems without worrying about delayed button response.
