How we take a look at Thunderbolt and DisplayLink docks at PCWorld
Choosing the actual Thunderbolt and DisplayLink dock simply can’t be performed with an seek recordsdata from on specs alone. It’s a course of that can desire time and sources, nonetheless pays off in the boldness that I’ve reached the apt resolution about which Thunderbolt or DisplayLink docks are worth shopping for.
A docking characteristic for laptops customarily uses the USB-C port, over which one of two things can happen: the pc routes a 10Gbps USB connection to the pc docking characteristic, or it uses a 40Gbps Thunderbolt connection as a replace. Extra extremely efficient Thunderbolt docks emerged as a must-enjoy software program at some stage in the pandemic, when many of us chanced on themselves working at house and realized that their PCs lacked the upright kind or preference of ports to connect with all of their peripherals.
Different publications might perchance perchance treat Thunderbolt docks as a single product class. We ogle them as a segment of a spectrum of pc docking stations that includes the raw 40Gbps energy of the finest Thunderbolt docking stations on one end, and more radiant, cheaper 10Gbps USB-C hubs and dongles on the opposite. In between are what are is assumed as DisplayLink docks that utilize proprietary recordsdata compression from Synaptics to pause Thunderbolt capabilities at decrease costs, and a connected class of USB-C docks that utilize an birth abilities referred to as DSC with HBR3.
We take a look at Thunderbolt docks and DisplayLink/DSC USB-C docks the utilize of the equivalent suggestions. We separate USB-C dongles into their comprise roundup, with their comprise assessments. All of them half something in general, on the other hand: They’re designed to permit your pc to connect with more peripherals and displays than that you just might in any other case comprise doable.
PCWorld’s checking out criteria for Thunderbolt and DisplayLink docks
I take a look at Thunderbolt and DisplayLink docking stations for laptops the utilize of a characteristic of general criteria, below. As we display in our roundup of the actual DisplayLink docks, a Thunderbolt 3/4 dock uses raw throughput of 40Gbps to transfer recordsdata. A DisplayLink dock uses compresses recordsdata over a 10Gbps (or 40Gbps Thunderbolt) connection to pause a identical perform. I don’t essentially request that the 2 classes of docks will assemble similarly, nonetheless the checking out components are simply about equivalent:
- Mark, and the map it compares to competitors
- The preference of ports/explicit aspects, equivalent to the preference of displays it connects to
- Stability, including whether peripherals without warning disconnect
- Whether or now not it delivers the promised energy to the pc and the dock’s peripherals
- Efficiency, both in streaming and storage
All of the Thunderbolt and DisplayLink docks we review are supplied by the distributors and then assessed by myself or other PCWorld workers with total editorial independence. Our choices are made via hands-on checking out, and we are by no map influenced by exterior parties.
How I enjoy in mind Thunderbolt and DisplayLink docks on mark
My course of begins with entering the Thunderbolt or DisplayLink dock into our database. Which can perchance appear irrelevant, nonetheless it in fact additionally forces me to envision its mark and availability. Is it correct readily accessible from the vendor, or from more than one retailers? Is the worth the equivalent in any appreciate of them, or is there a sale that can make it more elegant to a reader?
Thunderbolt docks pushed up into the $300 differ at some stage in the pandemic, and that’s on the total reflected in the MSRP pricing that accompanies our experiences. DisplayLink docks supply a cheaper different, down below $200. Nevertheless dock makers in general enjoy pushed laborious to diminish costs as supply chains enjoy eased and competitors has intensified.
How I enjoy in mind Thunderbolt and DisplayLink docks on aspects
Mark and aspects stagger hand in hand. Most Thunderbolt and DisplayLink docks are labeled as an “X-in-1,” where you might perchance also retract from an 8-in-1 dock, or a 10-in-1 dock, or any other mixture. This on the total is a tiny bit subjective. Attain you, the consumer, need 30 USB-A ports? Clearly now not. Nevertheless are seven ports better than 5? I enjoy to see at the worth a dock maker charges and then compare it to how accommodating the manufacturer is. A good warranty is a plus, too.
It’s here that I birth to see at the physical dock itself. After I desire away the dock from the packaging, I measure it to envision that it suits the broadcast specs. Whereas I don’t care too essential referring to the dimensions of the dock itself, the dimensions of the Thunderbolt or USB-C twine issues.
What which map is that selecting the apt dock is a dance between mark, ports, and promises. I’m taking a note for the actual mixture of aspects at potentially the most inexpensive doable mark, and I’ll on the total alter my rankings simply on account of a foremost mark decrease.
I in fact strive to now not study what any merchants must convey on net sites esteem Amazon, as I’d decide to assemble my comprise opinions. Nevertheless I perform stagger lend a hand and browse them before I file my review, in case I’ve neglected the rest explicit that’s worth additional checking out.
How I take a look at Thunderbolt and DisplayLink docks for balance
Now it’s time to connect. I walk the dock on a take a look at pc I enjoy characteristic up for the cause, and take a look at for balance: After I connect the display cables, perform they desire a actually very long time to connect? Attain the displays flicker or refuse to flip on? Does the dock require any utility software program to be loaded? (The resolution is often no, nonetheless DisplayLink requires a software program driver.) I then reboot and take a look at again.
The effort with checking out docking stations is that one take a look at pc doesn’t decrease it. Thunderbolt 3 docks on the total is a tiny bit glitchy, in that connected displays can flicker or even disconnect. Thunderbolt 4 docks had been designed to solve this effort, with an incremental nonetheless more restrictive specification. Nevertheless a apt Thunderbolt trip relies on both the host pc as neatly as the dock. In flip, I connect every dock to 5 take a look at laptops with varied substances interior, including 10th-gen to 14th-gen Intel Core chips and an AMD Ryzen 7000 notebook. I utilize the cables and energy supply that the dock ships with.
DisplayLink docks are on the total a long way more stable. Nevertheless my expectations are additionally increased with these merchandise, too.

Thunderbolt 3/4 docking stations are alleged to reliably connect with two 4K displays operating at 60Hz. Some — Thunderbolt and DisplayLink docks alike — utilize compression to connect with four 4K displays at 60Hz. Many additionally tout the capability to connect with a single 8K display at 30Hz.
I enjoy four 4K displays readily accessible, one which is rated at 144Hz. I will on account of this reality take a look at docks that claim that they are going to connect as a lot as four 4K displays, though I lack an 8K display to envision that skill. When Thunderbolt 5 arrives (three 4K displays, at 144Hz every) I’ll must make investments in more hardware.
It’s then lend a hand to my on a usual basis work pc for a day or two of popular utilize, as a additional take a look at. I’m additionally a gamer, so I’ll switch to a gaming pc in the evening and note how it handles these, too. Here is all in the carrier of balance. If the displays flicker or disconnect, that’s depraved news.
Many docks now give a enhance to as a lot as 2.5Gbps Ethernet. I don’t enjoy compile entry to to a 2.5Gbps Ethernet connection, nonetheless I will and perform take a look at the Ethernet connection on my house connection which runs into the many of of megabits. I additionally take a look at the dock’s headphone jack and the quality of the audio.
How I take a look at Thunderbolt and DisplayLink docks for their capability to supply energy
Many contemporary docks advertise their capability to fee your smartphone via a dedicated energy brick that sends energy via the dock.
In actual fact, simply about any port that gives energy will in the waste fee a smartphone; I’m correct taking a note for one that can perform at its rated energy level. I utilize a USB multimeter to envision how essential energy every port gives, connecting it to a smartphone.
I perform the equivalent for the pc itself. Most laptops don’t in fact settle on as essential energy as this day’s excessive-end docks present. For that, I originate an intensive 3D game, then file the peak energy the dock gives over the cable.

How I take a look at Thunderbolt and DisplayLink docks for efficiency
I complement my balance assessments by checking out both classes of dock below several usage eventualities to see if there are any surprising slowdowns as the dock transfers recordsdata.
Using a take a look at pc that I utilize for every dock take a look at, I circulate 4K60 video from YouTube over the Ethernet connection as neatly as a prerecorded video the utilize of the VLC video player. Both applications can note how many, if any, frames are dropped. I circulate at the least 10,000 frames on YouTube and display the preference of dropped frames; the actual descend below 10 frames, whereas sad-quality docks from time to time descend over 100. Dropped frames translate into stuttery, uneven video playback.
I then connect a take a look at, bus-powered SSD to the dock. Using PCMark 10’s storage benchmark, I measure the SSD’s efficiency. Since I utilize the equivalent pc and the SSD from take a look at to envision, the actual variable must be the dock itself. (House windows updates might perchance additionally enjoy an perform.) I display the ranking and the throughput and compare them to other docks I take a look at. I then repeat the take a look at whereas streaming video.
In the waste, I file the time it takes to repeat a multi-gigabyte folder fat of more than a couple of files from the dock to the pc over the Thunderbolt 4 bus, then repeat the take a look at whereas streaming video. Here is often overkill, nonetheless I enjoy to desire a note at and saturate the Thunderbolt bus if doable and route as essential recordsdata via the dock itself.
Thunderbolt docks tend to assemble more poorly than DisplayLink docks in these efficiency assessments, though now not by essential. That’s seemingly on account of the compression DisplayLink docks make utilize of.
I don’t educate the equivalent rigor to any SD or microSD card slots the dock has. I flee a easy storage take a look at, with the actual card, to see if it delivers on its rated flee.
How to clarify our Thunderbolt and DisplayLink dock ranking system
I award an Editor’s Alternative award if the dock is stable, performs neatly, delivers the rated energy that it promises, and at a competitive mark. I will mark down for instability or technical system faults, or other deficiencies. In some instances, I will also now not subtract that essential from the ranking of a characteristic that I don’t enjoy in mind foremost; one recent dock suffered from sad audio, nonetheless it in fact’s a characteristic that’s chanced on on simply about all laptops. Our Most efficient Picks for Thunderbolt and DisplayLink docks will on the total display docks that we’ve reviewed and perform now not meet our criteria, nonetheless now not often.
An Editor’s Alternative award will be assigned to a product with four stars or above, nonetheless by no map below. In transient, I will finest set an Editor’s Alternative award to a dock that I’d utilize myself and would recommend to a friend or member of the family.
