Selore USB C Dock 3 HDMI Review
Selore USB C Dock 3 HDMI transforms your laptop into a tech symphony. With 16 ports and triple HDMI, it's a Swiss Army knife for digital nomads seeking order.
The Selore 16-in-1 gives you three HDMI ports that each output 4K. Three monitors from a single USB-C connection. On Windows, all three run independently with different content on each screen. That is a four-screen workspace including your laptop display. At 0.32 kg (0.7 lbs), it is light enough to throw in a bag. It charges your laptop at 100W through pass-through PD. It transfers data at 10 Gbps through USB-A 3.1 and USB-C 3.1 ports. It reads SD and microSD cards. It provides Gigabit Ethernet. It has a 3.5mm audio jack. Sixteen ports from one USB-C cable, with a two-year warranty.
The Mac limitation is important and clearly stated: on macOS, the three HDMI ports work in Mirror Mode only. You cannot extend three different screens on a Mac through this dock. This is a macOS restriction, not a Selore hardware limitation. If you are on Windows, you get the full triple-monitor independent display experience. If you are on Mac, you get three mirrors of the same screen. That distinction is the single most important buying detail for this product.

Three HDMI Ports: The Resolution Reality
Three HDMI ports on a USB-C hub sounds straightforward until you look at the resolution breakdown. The Selore supports different configurations depending on how many monitors you connect:
One monitor: 4K@60Hz. Full resolution, full refresh rate. The bandwidth is dedicated to a single display.
Three monitors simultaneously: 4K@30Hz on each. The 30Hz means the screens refresh 30 times per second instead of 60. For static content (documents, spreadsheets, email, code), 30Hz is functional. For video playback, scrolling, and cursor movement, 30Hz feels noticeably less smooth than 60Hz. If you watch video on one screen while working on the other two, the video screen will look choppier than a dedicated 60Hz display.
Two monitors at 1080p@60Hz simultaneously. Lower resolution but full refresh rate on both. This is the configuration that feels smoothest for daily use if you do not need 4K.
Understanding these trade-offs before purchasing prevents disappointment. If you expected three monitors all running at 4K@60Hz independently, that requires more bandwidth than a USB-C hub can provide. The Selore is honest about the limitations in the bullets. For USB-C bandwidth limitations, see our USB-C portable monitor guide.
The Mac Mirror Mode Limitation
This needs its own section because it is the most common source of buyer frustration with multi-HDMI docks. On Windows, all three HDMI ports work independently. Three different screens showing three different things. On macOS, the three ports work in Mirror Mode only. All three monitors display the same image. You cannot extend your Mac desktop across three screens through this dock.
This is not a Selore problem. It is a macOS limitation with how the operating system handles multiple displays through USB-C hubs that use MST (Multi-Stream Transport) technology. The dock works exactly as described on Mac. It just mirrors instead of extending.
If you are a Mac user reading this review, here is what you need to know. Mirror Mode means all three monitors show your laptop screen. That is useful for one scenario: presentations where multiple screens face different parts of an audience. For every other use case (independent desktops, different apps on different screens, extended workspace), Mirror Mode is not what you want.
Your options for extended triple displays on Mac: use a MacBook with M1 Pro, M1 Max, M2 Pro, M2 Max, M3 Pro, or M3 Max (these chips support multiple displays natively) with a Thunderbolt 4 dock. Or use a DisplayLink-based dock with DisplayLink software installed on your Mac, which bypasses the macOS limitation through software rendering. The Selore does not use DisplayLink. If you need Mac extended displays, this is not the dock. For Mac-compatible docking options, see our best bundles for MacBook users.
16 Ports at 0.7 lbs
At 0.32 kg (0.7 lbs), the Selore is remarkably light for a 16-port dock. The plastic enclosure keeps the weight down. For context, the Anker 778 Thunderbolt 4 dock weighs 1.28 lbs with 12 ports. The Dell WD22TB4 weighs 4.0 lbs with 11 ports. The Selore provides more ports at less than half the weight of the lightest competing dock on this site.
The trade-off is build material. Plastic does not dissipate heat as well as aluminum and is less durable under stress. For a desk-based hub that does not get moved frequently, the plastic enclosure is fine. For a hub that travels daily in a backpack, the lighter weight is an advantage but the plastic needs more careful handling than a metal-bodied dock.
100W PD Pass-Through Without Included Adapter
The Selore passes up to 100W of charging power through to your laptop. You supply the charger. The box does not include a power adapter. If you already own a 100W USB-C PD charger, connect it to the dock’s PD port and the dock routes power to the laptop through the same USB-C connection that carries video and data. If you do not own one, add that cost to the purchase.
100W covers the full range of consumer laptops (typically 45-65W) and most workstation-class machines (65-96W). The dock draws its own operating power from the same source, so the actual wattage reaching your laptop is slightly less than 100W.
The Other 13 Ports: Quick Reference
The triple HDMI is the headline. The remaining ports round out the dock for daily use. The 10 Gbps USB-A 3.1 and two USB-C 3.1 ports handle external SSDs and fast drives. Two USB-A 3.0 ports at 5 Gbps cover flash drives and standard peripherals. Two USB-A 2.0 ports handle keyboards, mice, and webcams. SD and microSD slots read camera and drone cards without a separate reader. Gigabit Ethernet provides wired network stability that WiFi cannot match during video calls and large transfers. The 3.5mm audio jack handles headsets and desktop speakers, a port many competing hubs skip. These ports are table stakes for a 16-port dock. They work. They are there. The buying decision lives in the triple HDMI, the Mac limitation, and the resolution trade-offs above.
Which Triple Configuration Should You Choose?
This is the question the Amazon listing does not answer. You have three options and each one suits a different workflow:
If you are a stock trader, financial analyst, or data professional who runs dashboards across three screens and the content is mostly static (numbers, charts, tables that update periodically), use three monitors at 4K@30Hz. The higher resolution shows more data per screen. The 30Hz refresh is irrelevant because the content barely moves.
If you are a content creator, video editor, or someone who watches media on one screen while working on others, use one monitor at 4K@60Hz for the media screen and reduce the other two. The 60Hz gives smooth video playback where you need it. The working screens handle documents at lower resolution without issue.
If you are a general productivity user who values smooth cursor movement, scrolling, and overall responsiveness across all screens equally, use two monitors at 1080p@60Hz. Lower resolution but everything feels fluid. Add your laptop display as the third screen.
No one on Amazon is telling buyers which configuration to choose for their specific work. This guidance is the difference between a satisfied buyer and a confused one.

Who This Dock Is For
Windows users who want three independent 4K monitors from one USB-C connection at minimal weight: The Selore is the lightest dock on this site that provides triple HDMI output. Sixteen ports cover monitors, peripherals, storage, network, audio, and charging. 10 Gbps USB 3.1 ports handle fast data transfer. 100W PD keeps the laptop charged. The two-year warranty is above the 18-month standard that Anker provides. At 0.7 lbs it travels without adding meaningful weight. For a triple-monitor docking alternative, see the Laptop Docking Station 3 Monitors review.
Mac users who need extended (not mirrored) triple displays: This dock mirrors only on Mac. If you need three independent screens on macOS, you need a Thunderbolt 4 dock with a Mac that natively supports multiple displays, or a DisplayLink-based solution. For docking options with different Mac capabilities, see our docking stations hub page.
Final Verdict
The Selore 16-in-1 packs the most ports of any USB-C hub on this site into the lightest body. Triple HDMI, 10 Gbps USB, 100W PD, Gigabit Ethernet, SD/microSD, and 3.5mm audio in a 0.7 lb plastic enclosure with a two-year warranty. On Windows, three independent 4K monitors from one USB-C cable is the headline capability. The resolution trade-offs (4K@30Hz triple, 4K@60Hz single, 1080p@60Hz dual) are honest and clearly documented.
The Mac Mirror Mode limitation is the deal-breaker for macOS users who need extended displays. The plastic build and missing power adapter are the practical compromises. For Windows users who want the maximum port count and triple monitor output at the minimum weight, the Selore provides that combination. The two-year warranty adds confidence. For Mac extended display needs, other solutions are required.
Frequently Asked Questions
Can I run three 4K monitors at 60Hz?
No. Three monitors run at 4K@30Hz simultaneously. A single monitor runs at 4K@60Hz. Two monitors run at 1080p@60Hz. The USB-C bandwidth limits how much resolution and refresh rate the dock can deliver across multiple screens. Choose your configuration based on whether you prioritize resolution (4K@30Hz) or smoothness (1080p@60Hz).
Why can’t Mac extend three screens?
macOS restricts how multiple displays are handled through USB-C hubs that use the display technology this dock employs. On Mac, the three HDMI ports output the same mirrored image. This is a macOS limitation, not a Selore hardware issue. Windows does not have this restriction.
Do I need a power adapter?
For the 100W pass-through charging, yes. The box includes the dock, a USB-C cable, and a manual. No power adapter. If you want the dock to charge your laptop while you work, you need to supply a 100W USB-C PD charger.
Is the plastic enclosure a concern?
For a desk hub that stays in one place, no. Plastic keeps the weight at 0.7 lbs, which is less than half the weight of most competing docks. For daily bag carry with rough handling, aluminum-bodied docks are more durable. The Selore prioritizes port count and weight over build material.
What does DP Alt Mode mean?
DisplayPort Alternate Mode allows a USB-C port to carry video signal in addition to data and power. Not all USB-C ports support DP Alt Mode. If your laptop’s USB-C port is charging-only or data-only, the HDMI ports on this dock will not output video. Check your laptop’s specifications to confirm DP Alt Mode support before purchasing.

Docking Station Intelligence
The standards are confusing by design. These three panels decode what manufacturers won’t explain clearly. Applicable to every docking station.
The USB-C Confusion Matrix
The USB-C connector is the single greatest source of buyer confusion in docking stations. The physical plug looks identical whether it carries USB 2.0 at 480 Mbps or Thunderbolt 5 at 120 Gbps — a 250x difference in capability hidden behind the same shape. Manufacturers exploit this by labeling everything "USB-C compatible" without specifying which protocol runs through it. Two docks can look identical on the outside and behave completely differently once you plug them in.
The hierarchy matters because it determines everything: how many monitors your dock can drive, how fast files transfer, whether your laptop charges while docked, and whether you need third-party drivers. Here is the real capability ladder, from slowest to fastest:
The practical takeaway: if your laptop has Thunderbolt 4, buy a Thunderbolt dock. If it only has generic USB-C, verify whether it supports DisplayPort Alt Mode before buying anything with multi-monitor claims. Our buying guide walks through verification steps for every major laptop brand.
Power Delivery: What the Watts Mean
Power Delivery (PD) determines whether your docking station can charge your laptop while you work, or whether you need a separate charger cluttering your desk. The math is simple but rarely explained: your laptop draws a specific wattage under load, and the dock must match or exceed it. If the dock delivers less than your laptop needs, the battery slowly drains even while plugged in — defeating the purpose of a docking station entirely.
Most ultrabooks need 45–65W. Standard business laptops need 65–100W. Gaming and workstation laptops can demand 100–140W or more. The dock’s advertised PD wattage is the maximum it can deliver to your laptop — but this drops if you charge other devices (phones, tablets) through the dock simultaneously. Always leave a 15–20W margin above your laptop’s requirement.
Check your laptop’s original charger wattage — that’s your baseline. Our FAQ covers how to find this for every major brand.
Native Display vs DisplayLink: The Hidden Factor
This is the decision most buyers don’t know they’re making. When a docking station outputs video to your monitors, it uses one of two fundamentally different methods: native (the dock passes your laptop’s GPU signal directly to the monitor) or DisplayLink (the dock compresses video over USB and a software driver renders it). The difference is invisible in marketing materials but profoundly affects your daily experience.
Native output through DisplayPort Alt Mode or Thunderbolt uses your laptop’s actual graphics hardware. There is zero added latency, full DRM support for streaming services, no CPU overhead, and no driver to install. DisplayLink, by contrast, adds 5–15ms of latency (noticeable in video calls and cursor movement), blocks DRM content on connected monitors (Netflix, Disney+ show black screens), consumes 3–8% of your CPU constantly, and requires a driver that Apple’s macOS security updates occasionally break.
DisplayLink exists for one reason: Apple Silicon base chips (M1, M2, M3) can only drive one external display natively. If you need two or more monitors on a base MacBook Air or 13” MacBook Pro, DisplayLink is your only option. For everyone else — Windows users, Mac Pro/Max chip users, Intel/AMD laptops — native is always the better choice.
Native (Alt Mode / Thunderbolt)
DisplayLink (USB compression)
The bottom line: if your laptop supports native multi-display output, always choose a native dock. DisplayLink is a workaround, not an upgrade. See our glossary for detailed definitions.
