Newmight Dual HDMI Adapter Review
Upgrade your desk with the Newmight Dual HDMI Adapter. This docking station transforms your workspace into a sleek, functional haven. Perfect for multitaskers!
Dual HDMI at 4K, Gigabit Ethernet, 100W PD charging, three USB 3.0, and SD/TF readers in a hub that weighs 100 grams. The Newmight 9-in-1 is one of the lightest dual-HDMI hubs on this site. On Windows, both HDMI ports extend independently through MST (Multi-Stream Transport) — two different screens showing two different things. On macOS, MST mode only supports mirroring (A-A-A) or a specific extend pattern (A-B-B) where both external monitors show the same content. For Mac users who need two independent external displays with different content, this hub does not provide that through MST. The listing mentions SST mode for Mac extend, but the practical behavior needs verification before purchasing.
Anodized aluminum alloy. 5.12″ x 1.85″ x 0.55″. DP Alt Mode required. Plug and play, no driver. 1-year warranty with lifetime technical support from Newmight.

Dual HDMI on Windows: Independent Extend
On Windows laptops with DP Alt Mode and MST support, both HDMI ports extend independently. Two monitors, two different screens, two different content. 4K@30Hz on each. This is the straightforward dual-monitor experience that Windows users expect from a dual-HDMI hub. Plug and play, no driver, two screens working within seconds.
4K@30Hz means scrolling and cursor movement appear slightly less smooth than 60Hz. For static productivity work (documents, code, spreadsheets, email), 30Hz at 4K is functional. For media editing or tasks that involve frequent scrolling, the lower refresh rate is noticeable. For 4K@60Hz on dual monitors, the iVANKY EdgeDock 1 or Anker 565 provide that at a higher price.
macOS MST Limitation: No Independent Dual Extend
On macOS, MST mode supports mirroring (A-A-A: laptop and both monitors show the same content) or a limited extend (A-B-B: laptop shows one thing, both external monitors show the same second thing). This means Mac users cannot use both HDMI ports to display two different external screens with different content through MST.
The listing mentions SST (Single-Stream Transport) mode for Mac extend, but does not explain what SST achieves in practice. SST typically routes one video stream per cable, which would support one extended display, not two. Mac users who need two independent external monitors with different content should consider DisplayLink docks or verify the SST behavior with Newmight’s customer service before purchasing. For Mac dual-display solutions, see our docking stations hub page.
100 Grams: Travel-Weight Hub
At 100 grams (3.5 oz), the Newmight weighs less than the Anker 555 (3.2 oz), the Lenovo 7-in-1 (1.73 oz), and the UGREEN Revodok (not specified). Among dual-HDMI hubs with Ethernet, this is a notably light option. The 5.12″ x 0.55″ profile slips into a laptop bag alongside the charger without adding meaningful bulk. For professionals who travel and need dual monitors at client sites, the weight matters.
100W PD Charging
The USB-C PD port passes through up to 100W from your charger to the laptop. The listing does not specify how much the hub consumes, so actual pass-through to the laptop may be slightly less. A 100W charger is recommended. The charger is not mentioned as included. Verify with the listing whether a charger ships in the box or whether you supply your own.
Drawbacks
| Consideration | Detail |
|---|---|
| macOS: No Independent Dual Extend | MST mirrors or shows same content on both externals (A-B-B). |
| 4K@30Hz | Not 60Hz. Scrolling less smooth. |
| DP Alt Mode Required | Not all USB-C ports support video output. |
| Hub Power Consumption Unknown | 100W pass-through may be less after hub overhead. |
| USB 3.0, Not Gen 2 | 5 Gbps, not 10 Gbps. |
| Lesser-Known Brand | Newmight has less market presence than Anker, Lenovo, or UGREEN. |
Who This Hub Is For
Windows laptop owners who need dual HDMI 4K with Ethernet, 100W PD, USB, and card readers in a 100-gram travel hub: On Windows, the Newmight provides independent dual extend at 4K@30Hz through MST without a driver. Nine ports at 3.5 oz with anodized aluminum. Gigabit Ethernet. SD/TF. 100W PD. 1-year warranty with lifetime support. For a dual-HDMI hub at this weight with Ethernet, the Newmight competes directly with hubs from larger brands at a potentially lower price point. For dual HDMI at 4K@60Hz, see the iVANKY EdgeDock 1 review.
Mac users who need two independent external displays: MST on macOS does not extend independently to two different screens. For Mac dual-display solutions, DisplayLink docks or native Thunderbolt docks with M-series Pro/Max chips provide that. See our docking stations hub page.
Final Verdict
The Newmight 9-in-1 provides dual HDMI 4K, Gigabit Ethernet, 100W PD, three USB 3.0, and SD/TF at 100 grams in anodized aluminum. On Windows, it delivers the dual-monitor experience as advertised. On macOS, the MST limitation restricts dual extend to mirroring or A-B-B, which does not provide two independent screens with different content. The 4K@30Hz refresh rate and USB 3.0 speed are standard for this price tier.
For Windows users who travel with a laptop and need dual monitors at every destination, the 100-gram weight and nine ports make the Newmight a practical carry. For Mac users, the macOS limitation makes this hub a single-monitor solution in practice. 1-year warranty with lifetime technical support from Newmight.
Frequently Asked Questions
Can I extend two different screens on my MacBook?
Not through MST mode. macOS MST supports mirroring (A-A-A) or A-B-B where both external monitors show the same content. For two independent Mac displays, use a DisplayLink dock or a native Thunderbolt dock with an M-series Pro/Max chip.
Why is 4K@30Hz and not 60Hz?
Dual 4K@60Hz requires more bandwidth than a single USB-C connection with MST can provide at this price tier. 4K@30Hz is the standard for dual-HDMI MST hubs. For dual 4K@60Hz, the iVANKY EdgeDock 1 provides that.
Is a charger included?
The listing does not clearly state whether a charger is included. The PD port passes through power from your charger. Verify with the seller or assume you need to supply a 100W USB-C PD charger.
How does this compare to the LASUNEY 14-in-1?
Newmight: 9 ports, dual HDMI, 100g, anodized aluminum. LASUNEY: 14 ports, dual HDMI + DisplayPort + VGA, aircraft-grade aluminum, heavier. LASUNEY has more video outputs and more USB ports. Newmight is lighter and simpler. Both have 4K@30Hz dual HDMI and the same macOS MST limitation.

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.
