Cable Matters Portable 8K or Dual 4K 60Hz USB C to Dual
Cable Matters Portable 8K or Dual 4K 60Hz USB C to Dual DisplayPort Adapter, Thunderbolt to Dual DP Adapter – Thunderbolt 4 Compatible for XPS, Surface Pro (macOS Supports one Extended Display)
Works great to add two DisplayPort ports to a compatible laptop or phone. Only complaint is that you can’t charge at the same time, so works better with a device with two or more USB-C ports.
This was a fully plug and play device. I just plugged it right into my laptop, and plugged in two displayport cables, and it works perfectly. No drivers or software were needed. It’s compact, the cord is a nice material and it very short so it won’t tangle or kink. This is a quality product for sure.
When using a laptop this can be invaluable to attach an external monitor or sometimes two–this works well and high quality. I have no issues with it, highly recommend this unit in using with a laptop directly or a docking station with compatible port.
I got this to use DisplayPort with my ThinkPad that only has HDMI and USB C. The additional HDMI port on the adapter is a bonus in case I use this for some other purpose, although the extra port makes it a bit bulky. One think to note is that you might not be able to see boot up screens, so this is really more for secondary monitors. This might be an issue/feature of my ThinkPad or USBC in general, but not sure. Seems to work fine otherwise. I was able to get 2K @144Hz, but don’t have the equipment to test the limits.
I have only used this on a windows based computer so I am not sure on how it will perform on a mac. But on a windows machine this is great. One thing to remember it is all based on your computer and what it can handle. I was able to use both outputs at 1080/60 plus using my screen and my computer was able to handle it perfectly fine. No jitters, no crazy installation, no crazy setup. You just plug in this adapter plus some HDMI cables and choose what you want the adapter to display and viola, you are done. I did try one output on a 4k TV and it worked perfectly fine. I was not able to find an 8K display so can not comment on that. The little slot to store the USB-C end is great that way you don’t have to worry about the end getting caught on anything or getting squished. Overall it is great and small enough to carry in your backpack or your pocket.
If you’re in need of this type of item, this is the one for you.
I occasionally need to do a split monitor setup while traveling, and this dual display adapter fills the bill for me. I use it seamlessly on a Surface tablet, and it has very little delay upon activating,with no loss of quality in the dual displays…all while packed in a very portable package.
Cable Matters is one of my go-to companies, and this adapter doesn’t disappoint.
This is a really portable and solid display port adapter. Works well when working remotely and in a pinch. Using it with the two monitors the connection is stable, I don’t notice any lag. I am working with a lenovo pc, so this works well with the Windows 11 OS for me. Worked all day with this with no loss in signal. Very happy with this.
I work as a audiovisual technician. I’m often setting up breakout rooms for conferences which include putting up projectors.
Once we get those projectors up it’s nice to have something on you that will allow for you to test the connection and ensure you’re getting a signal to the monitor. To do so I’ve been using this device connected to my iPhone 11 using a usb-c to lighting cable (you won’t need that extra cable for newer iPhones) allowing me to play a video from my phone and it displays on the projector.
This device also has a DisplayPort adapter which is perfect for when we’re using Apple products
Both the HDMI and the DisplayPort work wonderfully on this for a MacBook Air 2020 (M1). I have not had an opportunity to test if both work at once (the Air 2020 only supports one external monitor), but both adapter ports do work individually. I got this for my office as one of our hybrid users needed something that would work with her MacBook, but that would also support our monitor madness for whichever workstation she landed at for the day.
I also think this would be excellent for traveling as it has you covered for whatever monitor you are faced with.
I got this to solve some monitor issues with one of my Macs and, while I wasn’t able to solve them, it is no fault of this adapter! It performed flawlessly, the same as if no adapter was used, ultimately the limitation/compatibility issue was (is) with my Mac. I love the highly integrated design, it is basically as small as I could imagine it, any smaller it would be difficult to handle. It has earned a place in my travel bag because you never know when it will come in handy!
Review for: “Cable Matters Portable 8K or Dual 4K 60Hz USB C to HDMI and DisplayPort Adapter – Thunderbolt 4 and USB 4 Compatible for DELL XPS, Surface Pro, MacBook (macOS only Supports one Extended Display)”
I use this for my Core I9 based Dell Precision 5575 to connect two monitors: A Samsung 4K and a LG 4K monitor.
Both monitor can connect with 4K @ 60 Hz with HDR on without any problem. It is a space saver for traveling the laptop, so we don’t need to bring the bulky docking brick.
It works fine for QHD and 4K, couldn’t check the 8K output, but it is doing just fine running 2 extended 1080 desktops on my QHD laptop. No drivers, no setup for it – plug and play. Good build quality and it only gets a little bit warm. It’s a lot smaller than I was expecting too, it’s only about 3″ across. The Type C plug is on a little 2″ flat silicone cable and it tucks in to the box when not in use. I like it, it’s a keeper.
I really like the form factor of this, it makes it very easy to travel with. The adapter works great and does manage to function at the resolutions and refresh rates as claimed. It’s especially nice that it doesn’t require a separate power source, like some do. I just wish this supported DisplayPort 2.1 with dual 4k 120hz, it seems like such a minor thing to add support for and has been out for a while now, but not many devices do it.
This worked great for traveling – plugging in my device to a larger screen via HDMI that didn’t support wireless screen mirroring. It worked quickly, without a hitch and perfect for my needs.
I have a Surface Pro for my work computer, and it only has one USB Type A and one USB Type C ports. It has no video output.
When I’m working at home, I Ike to use my huge 49″ ultra widescreen monitor. I’d been using a Belkin DisplayPort adapter which was working fine when plugged directly into the monitor. I got tired of having to climb between my monitor to swap cables, so I decided to get a KVM to make switching from one PC to the other easier.
The KVM worked perfectly with my home computer which has a built-in DisplayPort jack, but when I tried my work Surface, I was getting flashing blocks of noise on the monitor. Something with the Belkin and the KVM wasn’t playing nicely with each other.
I really wanted to keep using the KVM, so I decided to order this adapter and see how it worked. I was going to get the dual DisplayPort model, but decided that I wanted HDMI for compatibility.
When it arrived, I was thrilled to see that the Cable Matters and my KVM got along together. My monitor is displaying perfectly, even at 240Hz.
I’m not sure what the problem was, but I can say that this one works, and the Belkin does not. The Belkin also cost around twice what this one did.
I also like that it is much smaller than what I was using before. This one is perfect for my work laptop because it takes up almost no space in my backpack.
If you’re looking for a DisplayPort adapter that works well, this is a good choice.
I tested this on my Macbook Air and on a Windows laptop. It was able to output to both monitors simultaneously in both cases. But like the listing title says, MacOS apparently won’t allow you to extend beyond one monitor with this device. You can however output to two external monitors they just mirror each other. But they still extend the screen.
But also from my understanding, the USB-C port you’re plugging this into will require a so-called “Alternative Mode” that supports DisplayPort. (Apparently if it’s an HDMI out adapter, the signal from the computer is DisplayPort but converted to HDMI). This is probably the case for laptops but don’t be surprised if it doesn’t work on a desktop. I think USB-C ports that support video output are supposed to have a monitor or displayport symbol next to them, but my laptop doesn’t but it still worked. But on my desktop it wouldn’t work with any of the USB-C ports.
