Introduction

Suppose you have a 4K monitor or two high refresh rate 1080p/1440p monitors and a laptop with a single USB-C port supporting video output. What is a straightforward and economical approach to get the full refresh rate capabilities of the monitors while also being able to use USB devices like a mouse and thumbdrive?

On many laptops, USB-C port bandwidth is limited such that you can only use 4K @ 60Hz OR USB 3.x @ 5Gb/s+ speeds, not both. For such laptops, USB devices must be limited to USB 2.0 speeds (480Mb/s) in order to achieve 4K @ 60Hz via DisplayPort 1.2 (DP 1.2) alternate mode. Most simple hubs on the market run USB devices at 5Gb/s which limits the monitor to 30Hz. For many users, this feels extremely slow/laggy even if they are not gamers. What’s worse is that marketing materials are rarely straightforward about monitor refresh rates. There are dozens of off-brand hubs on ebay, amazon, and aliexpress claiming 60Hz support (at least for 1080p) as well as 4K support. But what they don’t mention is that 4K always runs at 30Hz. Some of these devices have logic built in such that a monitor will run at 4K60 as long as no USB devices are plugged in. But as soon as a USB 3.x device is plugged in, the 4K monitor drops to 30Hz. Similarly, some will automatically limit USB speeds when a 4K60Hz capable monitor is detected, but this detection doesn’t always work properly.

More recent laptops implement DisplayPort 1.4 (DP 1.4) alternate mode with display stream compression (DSC) over USB-C which can run 1x or 2x 4K60 AND USB devices at 5Gb/s or faster simultaneously from the same USB-C port. Older hubs don’t take advantage of this capability and will still run monitors at 30Hz or limit USB speeds unnecessarily.

Below is a collection of economical USB-C hubs to extend your laptop to run 1x or 2x 4K monitors at 60Hz alongside USB devices. The minimum feature set to be considered for this list is:

  1. one or more HDMI or DisplayPort video ports supporting 4K60 via DP alt mode (not DisplayLink)
  2. one or more USB A-style ports
  3. 60W or more USB-C power delivery for laptop charging
  4. compact/portable
  5. $100 USD or less

4K60 USB-C hubs for laptops with DP 1.4

These hubs are well-suited for newer laptops which support DP1.4. Most of these hubs allow 1x 4K60 or 2x 4K30 monitors alongside 5Gb/s+ USB. Some laptops will also manage 2x 4K60 (see compatibility notes). Older laptops will work OK, but will run in DP1.2 alt mode which may limit monitor bandwidth to 1x 4K30 or 2x1080p. Users of older laptops should consider the DP1.2 hubs.

Compatibility notes

Even though spec sheets of various laptops may indicate DP1.4 and/or DSC capabilities, this technology is new and we’ve had many user reports of compatibility issues between various hubs and laptop models when trying to get the highest monitor resolutions to work alongside USB 3.x devices. For example, setting up 2x 4K60 monitors via multi-stream transport (MST) is particularly challenging on many laptops from 2019-2020 and almost impossible on systems based on the Intel 9th/10th Gen Core processors. Intel 11th Gen Core processors fare much better. I don’t have the resources to test all the combinations, but this list includes what should work if your PC implements DP 1.4 with DSC and MST properly.

If you have problems getting 2x 4K60 working on hubs that also support USB 3.x devices, email the laptop vendor and dock vendor and see if firmware updates are available. Many vendors have revised their specifications since launch to indicate only 1x 4K60 is possible.

A hub that limits USB devices to 2.0 speeds instead such as Cable Matters 201046 or 201355 is a better bet on problematic laptops and often will enable 2x 4K60 to work at the expense of slower speeds for your USB devices.

4K60 USB-C hubs for laptops with DP 1.2

These hubs limit USB peripheral speeds to USB 2.0 (480Mb/s) to ensure that a single monitor will run at 4K60 over DP1.2 alt mode. Example laptops in this category are Surface Book 2, Surface Go, Surface Go 2, and Surface Laptop Go. Newer, more capable laptops with DP1.4 will work fine, but DP1.4 hubs are a better choice for those systems.

54 thoughts on “Run your 4K monitors alongside USB devices from a single USB-C laptop port”

  1. Through your post is how I first learned that there are finally hubs that do PD passthrough and DP 1.4 with DSC. I have a Surface Laptop 3 and a monitor that provides PD power (and can do power/data/video on one cable, but only TB3, not USB) so now there is finally a hub which would allow me to get power, high res video and USB 3 via a single cable connected to the Surface Laptop 3….

    Well, sort of. I got the Cable Matters 201331-BLK and here are my impressions.

    First, power pass through and USB work fine.

    Video doesn’t work so smoothly, though.
    * So my monitor runs at 5120×2160 – a little over 4K. I can run it at max 30 Hz even though there should be enough bandwidth for 60 Hz. If it can do two monitors at 3840×2160@60Hz, adding that extra 1280×2160 screen area (way less than another 4K monitor) to get to 5K shouldn’t force it to go down to 30 Hz.
    * In fact with the prior adapter I used – Cable Matters 201046-BLK – I was able to run 5K60 + USB2. Now I have USB3, but only 5K30…
    * Things get even worse when I try to add another monitor. I thought, well maybe it forces the 30 Hz, so that you can still add other monitors at full resolution. I added a 2560×1600 monitor… and… it forces it down to 1280×800 (albeit at 60 Hz with no option to change it).

    I don’t know if there are any software tweaks to make it work well. Ultimately it delivers marginal utility.

    Maybe the CalDigit SOHO works better… That’s the other option with can do PD pass-through + 2+ DP 1.4 with DSC + USB3.

    • I couldn’t recreate my Surface GO / 2x2560x1440@60Hz setup with a cable matters 201055 dock on a Surface Laptop 3 either, bummer. Since there are no problems with other Intel 10Gen/11Gen LG laptops it’s fair to assume these Intel 10Gen Surface devices have some issues with their USB-C implementation, e.g. not achieving same resolution with an HBR2 gen dock yet not working with an HBR3 gen/DSC enabled dock either, I eventually bought a Matebook X Pro 2021 and a TB3 enabled LG 4K Ultrafine display to run a dual 4K 60Hz setup through daisy chaining another display

      • Hi, this is a great article thank you ! I read this through but unfortunately I couldn’t find the one I’m looking for…
        I have a single 2560x1440p @165hz monitor with a Display Port. A DP1.4 (or even a DP1.2) should work but what i understand so far is that since the docks work as an active device they need to be set to actually be able to display the 165Hz to work… And I can’t find a single dock at a reasonable price (not 300USD so to speak) that garantee this functionnality, nor even 144Hz which would be acceptable for me! (The 144hz could work with a HDMI 2.0)

        Plus I would love the dock to also have a micro/SD card reader, a 1Go ethernet port, and a couple USB A for keyboard and mouse… I don’t think it’s too crazy to ask for that.

        Have you ever come across a dock meeting these requirements? 🙂

        • The supported resolution is a function of the CPU. For DP1.4 you have the benefit of of a hardware compression protocol called DSC, but most docks do not utilize it. However your CPU may also be a limiting factor and may be limited to 1440p@60Hz. So we really need the exact model number to fully answer this.

          For USB C 3.2 gen 2 docks: Dockcase have DSC capability and works flawlessly when enabled from the menus. This also requires a CPU with support for DP1.4. SO what is the exact CPU model please? The reason it is important is that anything above 1440p@60Hz would otherwise require 4 lanes for DP-Alt Mode leaving none for USB. With DSC enabled, and providing the dock supports it, 2 lane mode is utilized, leaving 2 lanes for USB traffic and have those other ports like SD card, ethernet. I have their 8-in-1 detachable and confirmed DSC support when configured correctly on the dock, else will run in 4 lane mode by default, e.g. 4K@60Hz. Same would be true for their 9-in-1 as is the same hardware generation. They have some newer product now too, the 10-in-1 Explorer edition but the claims of dual 4k@60hz would require 2x2lane at DSC leaving none for USB again. Another option is products that utilize DisplayLink, which eliminates dependency on CPU and instead is a USB C GPU.

          For TB3 / TB4 docks: the options are quite different and these limits are removed, and would need to know if your laptop has these ports or not in order to recommend suitable equipment.

          • My Laptop has a Ryzen 7 7840HS CPU and a GeForce RTX 4070 (Laptop version) GPU

            The USB C on my laptop is specified to accept USB power and DisplayPort™ 1.4 in the datasheet, so my CPU should be compatible with the DSC protocol right?

            I also have an HDMI 2.1 port on my laptop which I currently use and it gives me a 144hz refresh rate on my monitor. But my monitor only support the full 165Hz through its display port.

          • This is great information and thank you.

            Option 1 $: The built in HDMI port would be most ideal to utilize the RTX 4070 in all honesty because it will be electrically connected to the dGPU. We can use an adapter from HDMI to DisplayPort. Here is a good article that talks about this. https://www.kensington.com/news/docking-connectivity-blog/difference-between-dp-and-dual-mode-display-video-ports/

            Option 2 $: When you use the USB C port on the RTX 4070 laptop, it is not electrically connected to the dGPU (some did though on RTX 3xxx laptops with VirtualLink ports) so other factors come into play. On your laptop we are utilizing DP-Alt mode via the CPU and you may find that directly connecting to the USB C port with a USB C to DP 1.4 adapter will run at the same resolution and refresh rate as the HDMI port.

            Option 3 $$ to $$$: Given that your USB C port is likely USB 4 (TB4), you have the benefit of some more advanced hardware docks with support for up to 3 displays, so DSC is less important when you have a USB4/TB4 dock. This comes down to budget though and if your goal is to have a single wire solution that will accomplish everything or would be happy with a couple-few wires to get the job done (option 1 and 2 above). USB4 (TB4) docks vary greatly in quality and feature performance so finding what is well documented can be a challenge. I have the Anker 5-in-1 TB4 dock and ran 1x4K@60Hz, 1x1080p@60Hz, 1xUSB C dock, 1xUSB A hub. All connected by a single wire to an 11th gen intel laptop. I would check eBay for used product for some known brand TB4 product. The Calldigit TS4 is the pinnacle in my opinion.

            Option 4 $$: If we stick with USB 3.2 gen 2 docks (less expensive) I turn to Dockcase as can force DisplayPort 1.4a to have DSC on (limits to 2 lane) or off (allows up to 4 lanes) via the built in dock display. I have tested this on their 8-in-1product (HDMI only). The newer 10-in-1 Explorer has two video ports (DP 1.4a and HDMI 2.1) and Kickstarter shows at $119 so would be a good fit in my opinion. https://www.kickstarter.com/projects/dockcaseexplorerepro/dockcase-smart-usb-c-hub-10-in-1-explorer-edition / https://www.dockcase.com/

  4. Probably silly question: in order to exploit 2x4k, does monitors need to support DP 1.4 too? In my case I have two BenQ PD3200U (4k panels). In the panel config I can choose between DP1.1 and DP1.2, does it mean they wont work at 4k60hz even if my surface pro 7 supports it?

    The new cable matters 201355 should be the ideal successor to this dock for people who already have a USB-C HBR3 equipped laptop like Surface Laptop3/4.
    Avoid the cable matters 201331, it’s promised dual4K output just isn’t working on most systems, probably due to the USB 3.0 ports eating away the bandwith.

  7. Hi
    I just bought an i-tec C31NANODOCKPROPD for my SP7 and 4K 60Hz didn’t work.
    Their support said that intel 10th gen G series CPUs only support DP1.4 in 4 lane mode, and not in 2 lane mode so 4K 60Hz won’t work with USB 3.
    What’s your experience?

      Yeah I’ve updated the article to list out some of the compat issues folks are having. The hubs that limit USB speeds to 2.0 certainly seem to work better with certain laptops from the late 2019/early 2020 era. Unfortunately, the Cable Matters 201355 is always out of stock – otherwise it would be my goto choice.

The CE-Link page is still misleading stating dual 4K60 in one spot but dual 4K30 in another. Clearly, DSC is not working on this dock.

  12. I don’t have surface, but a Lenovo Yoga Laptop with Ryzen7 4800 U. I don’t need 4K (my monitor only has 2560*1080@75Hz), but would like to have a USB-C Dock hat gives me Freesync and HDR. Both work over the HDMI-Port of my Laptop and over a USB-C to Displayport cable, but with none of my USB-C docks.
    As I understand it ‘normal’ USB-C docks could give me HDR (when they’re 4k60 capable), but for Freesync I would need a dock that doesn’t touch the DP Signal. So the Cable Matters 201046 should work. But it’s difficult to come by (for normal prices). I found also the Cable Matters 201246, which seems to be a related but a bit differend version, but on amazon it’s only specified as DP 1.2 and 4k60. Would it work with Freesync and HDR?
    Or are there other Docks that support both?

    • Oh Freesync / DisplayPort adaptive sync is a good question. I don’t see that in marketing materials for Docks. I think you’ll have to ask the vendor. I would assume that DP1.2 docks don’t have this capability unless they specifically mention it (which means they actually have DP1.2a).

      DP1.4 docks are far more likely to work, especially those limited to USB 2.0 like the hard-to-find CM 201046 and 201355. These ought to act exactly like your USB-C->DP adapter but just have a little USB 2.0 hub as well. If you can get your hands on one of these at a reasonable price, I think its worth a shot.

      For customers building gaming-oriented rigs, I always recommend plugging the monitor directly into the PC rather than through a Dock. High refresh, HDR, Sync, etc, just work better that way. It is a hassle to have multiple cables, but for gaming its really the best way.

        On the Packaging it says only “4K”. I’m a bit stumped, because having only USB 2.0 i’d guess that the DP Signal is 4Lanes untouched, but then it should support 8k. Is there even a way (or a reason) to dumb the signal down to dp 1.2?

  16. This is an awesome writeup! I was able to get four 4k60 displays running on a 2021 Zephyrus G15 (with the rtx3060) using two adapters. Wasn’t sure my laptop would handle that, but it’s working great. It’s even running the laptop display at 165hz at the same time.

    I used a Cable Matters 201355 and (since I couldn’t find another in stock) a 201375. It appears to be the same thing just without the USB ports and doesn’t have any trouble doing dual 4k60.

  18. There is an awesome set of updated USB C dock products by Dockcase, that have much granular control for things like forcing 2-4 lane and if supported will trigger DSC on. So 4K 60Hz on 2 lanes over HDMI works flawlessly with this dock. The USB Ethernet stays powered off when there is no link. It is worth noting that the Ethenet get up to 75 degrees C at 1Gbps and much cooler if running at 100Mbps link speed. The downside on this dock is that despite the built in fan, there is little to no cooling, which I believe is lack of air inlets. The ports might be part of the air flow design, but in practice, I don’t see this working. Makes me think about drilling holes in it to address.

  19. Hello,
    I got my Lenovo IdeaPad 5 Pro ARH7 this week. In the lenovo manual i cannot figure out if it has DP1.4 but i read somewhere that it has! But i‘m not sure 😦
    I would like to deliver 240hz on my 1080p monitor. Can someone suggest a hub for my use-case?

    I just want to use the hub for video+keyboard+mouse+headphones
    Thanks in advance!

  22. How would this change if the source is an android phone, rather than a laptop?
    I have a UPerfect X Pro Laptopdock – 4k, 60hz, touch, keyboard/,mouse.
    I’m trying to connect to an android phone (one touch 9 pro), but so far I can either get the display working, or the keyboard. (over usbc)

    It’s undocumented online, but the manual lists:
    2) Type-C OTG Port: Can be connected to mouse and keyboard.
    4) PD Port: Only for power supply
    5) Type C Port For Both signal transmission and power supply
    6) Mini HDMI port

    It suggests I can get this working by plugging a pd charger into the monitor, then a single USB-C Cable from the monitor to the phone (or laptop) but for the life of me I can’t seem to find a working config, including via HDMI.

    FWIW I can get video output via my phone to the Type C port with
    Manufacturers cable
    a CableMatters 10GB cable
    Cable Matters Thunderbolt 4 cable

    but not:
