Why the Hz number matters as much as the resolution
Two splitters can both be labelled “4K” and still behave very differently, because the refresh rate – the Hz figure – determines how often the picture updates each second. A higher refresh rate gives smoother motion, which matters more for gaming and fast-moving video than it does for static slides or a signage display.
Entry-level splitters such as the UGREEN 90805 1-IN-4 OUT HDMI SPLITTER 4K@30HZ (Rs. 8,930) and the UNITEK V1132A01-EU HDMI SPLITTER 1 IN 8 OUT 4K@30HZ (Rs. 24,741) top out at 4K@30Hz – perfectly fine for signage, presentation slides or basic mirroring, but less ideal for fast-motion gaming or live sports.
Step up to 4K@60Hz with a splitter like the UGREEN 90806 1-IN-4 OUT HDMI SPLITTER 4K@60HZ (Rs. 10,810), built on HDMI 2.0 with 18Gbps of bandwidth, and you get noticeably smoother motion for movies, sports and games across all four connected displays.
At the very top of this range sits the UNITEK V1163A HDMI BIDIRECTIONAL SWITCH (Rs. 11,054), which runs on HDMI 2.1 and supports up to 8K@60Hz or 4K@120Hz, along with Dynamic HDR and Dolby Vision. It is worth noting this is a 2-in-1-out / 1-in-2-out switch rather than a multi-output splitter, but it shows how far the resolution and refresh rate ceiling can go in this category.
Bandwidth and HDCP: the fine print
Bandwidth, measured in Gbps, is what actually carries the resolution and refresh rate down the cable. The UGREEN 90806 and the UGREEN 50966 bidirectional switcher both specify 18Gbps on HDMI 2.0, while the UNITEK V1163A’s HDMI 2.1 connection is built for the higher bandwidth that 8K or 4K@120Hz signals require. It is also worth checking HDCP version support – most splitters in this range list HDCP 2.2/1.4, which protected 4K content from streaming services and Blu-ray players typically requires.
Matching resolution to your actual displays
Some splitters list separate input and output resolutions. The UNITEK V1109A 4K HDMI SPLITTER 1 IN 4 OUT (Rs. 10,500) accepts a 4K input but distributes at up to Full HD 1080p on its outputs – a detail worth checking carefully if your source is 4K but you expect a 4K picture on every connected display.
Frequently Asked Questions
What is the practical difference between 4K@30Hz and 4K@60Hz?
Both deliver 4K resolution, but 60Hz refreshes the picture twice as often as 30Hz, giving noticeably smoother motion. This matters for gaming and fast video, and matters far less for static signage or slideshows.
Which product in this range supports the highest resolution?
The UNITEK V1163A HDMI Bidirectional Switch (Rs. 11,054) tops the list with 8K@60Hz and 4K@120Hz support over HDMI 2.1.
Do I need to match bandwidth to my source device?
Yes. Devices such as the UGREEN 90806 and UGREEN 50966 specify 18Gbps HDMI 2.0 bandwidth, which is sufficient for 4K@60Hz. Higher-bandwidth HDMI 2.1 devices like the UNITEK V1163A are needed for 8K or 4K@120Hz signals.
What is HDCP and why does it matter?
HDCP is a copy-protection handshake required by many streaming and Blu-ray sources. Most splitters in this range list HDCP 2.2/1.4 support, which is needed for protected 4K content to display correctly on every connected screen.
