64 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
['The Cyberguys 121 0030 offers three HDMI outputs from a single input in a black form factor. It connects via HDMI and is aimed at users who need basic 1-to-3 signal distribution without paying a premium.', 'At $21.99 it costs a bit more than some bare-bones 3-port splitters, but the 4,000 monthly purchases indicate strong market adoption, likely driven by business and education buyers who need reliable duplicated displays for presentations or digital signage.', "The 4.0-star rating reflects a product that generally works but has a noisier spread of buyer experiences compared to Orei's similarly priced splitters. Given the lower review volume, it is worth checking current Amazon reviews for any recurring complaints about specific source or display combinations."]
Pros
- 3 HDMI outputs from one input covers most multi-display mirroring needs
- High monthly purchase volume of roughly 4,000 units signals real-world demand
- HDMI connectivity, plug-and-play operation
- Black design blends into most AV setups
Cons
- Only 64 reviews makes the 4.0-star average less reliable than competitors with larger samples
- No 4K or HDR specs published
- Slightly higher price than comparable 3-port options from Orei
Performance notes
3 HDMI ports, HDMI connectivity. No resolution, refresh rate, or HDR spec published. Signal mirroring only, not switching. Verify compatibility with your specific source and display combination before purchase.
What buyers say
With just 64 reviews at 4.0 stars, the sentiment picture is limited. The high monthly purchase rate suggests the product is being bought in volume, but individual feedback is thin. Buyers who do leave reviews tend to report basic functionality working, with occasional compatibility notes around specific TV models.

Frequently asked questions
Is this the same as an HDMI switch?
No. The Cyberguys 121 0030 is a splitter, not a switch. A splitter takes one input and sends the same signal to multiple outputs simultaneously. A switch does the opposite: it takes multiple inputs and lets you select which one goes to a single display. If you have three devices and one TV, you need an HDMI switch, not this splitter.
Does it require a separate power adapter?
Cyberguys does not publish clear power requirement details in the spec listing. Many 3-port HDMI splitters at this price require a USB or barrel-jack power supply to drive all three outputs reliably. Check the current product listing for power accessory details before ordering, especially if you plan to use it with longer HDMI cables.
