Dual-Laptop USB-C KVM Docking Station, Dual Monitor 4K 60Hz DisplayPort Dock, 5-Port USB Hub, GbE, 90W/45W Power Delivery to Two Laptops, Windows/Mac, 2-Host KVM Dock, TAA

I'd been looking forever for some way to connect my Windows 10 and Windows 11 PCs (both with Thunderbolt ports, to enable a single cable for both power and data) to two monitors, external microphone, webcam, speakers and other USB drives. After I pre-ordered it, I'ld been waiting patiently for nearly a week until just today, it finally arrived. All I can say is WOW... FINALLY! It comes with a single power supply that simultaneously provides 90 watts to the active laptop and 45 watts to the standby PC, keeping both charged at all times with no issues. Again to reiterate... ONE power supply powering the switch AND both laptops, and only ONE cable to each PC... THAT'S IT. (Besides the obvious cables to all the peripherals.) Switching can be done either with the button on the front of the KVM or; if you install the Startech.com Link software, via a hotkey (double pressing the left shift button twice in rapid succession.) AND; although slightly buggy (I've already spoken to their tech support over this) you have SIMULTANIOUS mouse and keyboard control over both computers, merely by moving the mouse over to one side or the other. (But the hiccup in my case is that it doesn't ever seem to want to leave the Windows 10 machine, whether that machine happens to be the active or standby machine.) Other than that minute item, everything works PERFECT and exactly as you would expect it to. Again... FINALLY and THANK YOU STARTECH!

Of the 4 different dual-display KVM's that I tried , this is the easiest and most dependable. BEST SOLUTION FOR MAC. . #1 Support DIsplayLink on Mac. This is required on mac for extended desktop support. #2 ONE BUTTON PUSH to switch between computers. My setup is a 14" Macbook Pro M1 and PC Tower Ryzen 5950X/AsRock-Taichi MB/GIgabyte Titan-Ridge TB3 PCI card/RTX 3080/etc #3 Supports Huion 24" HDMI (w DVI adaptor) and its USB Pen Display input. #4 Quick recovery of display when MacBook is disconnected and then reconnected. Or when the KVM is switched off. Comparing the StarTech to the others, aside from VisionTech, all come in plain brown boxes with minimal packaging. Ordered lowest to highest price: A: VisionTek VT2900 - Nearly half the price of the others. Light weight and cheaply made feeling, Thin plastic. No support of DIsplaylink on Mac. Extended display only on PC, Mac is mirroring only. Has slower USB ports only, 1x DP 1x HDMI. B: Startech 129N-USBC-KVM-Dock - Lacking the extra HDMI port, but switching takes only 1 button push vs 2 on the others. Glowing front light is not overly bright. Plastic case, that feels solid, comparable to Targus, much better than VisionTech. Most reliable display recovery from disconnects.2x DP All other ports same between B,C,D. BEST SOLUTION FOR MAC. C: IOGEAR GUD3CDHTAA - Full metal housing, feels study and heavy weight. Has HDMI port for 3 monitor support. Macbook disconnect recovery was slower and not as reliable as the Startech, often needing to be reset. 2 button pushes (due to the HDMI port) made it confusing what PC was active. Glowing front blue LED is way too bright, and I needed to cover it. 2xDP 1xHDMI All other ports same between B,C,D. D: Targus DOCK750UsZ - Plastic case, that feels slightly more solid than Startech.. Has LED indicators on the mode switch that help reduce the confusion on 2 button presses to switch. Includes usb cables that have screws to secure them to the device. Manual provides some trouble shooting tips, something the others all lack. 2xDP 1xHDMI All other ports same between B,C,D. These are much more pricey than other KVM solutions but use far fewer cables, and offer better hub support

Amazing find, after a month researching, buying and returning equipment, I found this unit. I'm able to connect a MacBook Air M3 and a DELL Vostro 14 5410, drive two 4K displays flawlessly, all ports work really well, and power distribution works for both laptops simultaneously. You do need to install a set of display app/drivers for MacOS for the MacBook to be able to extend two 4K screens.

Had high hopes. Item DOA. Connects to both macbooks but one wont charge at all. Select button that switches the host does NOTHING despite tapping it, holding it down for 5 seconds to reset, power cycling the unit, reseating host cables on both ends, etc. Way. too expensive to be a hunk of junk like this. Glorified dock and the whole KVM aspect is garbage.

My original configuration consisted of an HP Laptop connected to an HP docking station (USB-C G5) and a Lenovo laptop connected to a Lenovo docking station (40AF0135US). Both docking stations had dual Display Ports and both docking stations connected to a Startech.com KVM (SV231DPDDUA2) Connected the KVM was a pair of LG Ultrawide Monitors, Logi Webcam (C922x Pro) , Logi Unifying receiver for a wireless keyboard and mouse, and a Jabra 410 Speaker. I will also note that since the KVM did not have an ethernet port, I had cat5 cables running to both docs. My objective in purchasing the Startech 129N-USBC-KVM-DOCK 129N was to replace both docking stations with a single device greatly cutting down on the amount of cables I had to use. PRO’s: Where the 129N shines is in its style, singe USB-C connectivity to both laptops, dual display ports and keyboard switching (shift shift quickly). Both monitors ran at a clean 2569x1080. A single Ethernet cable was also nice. This device will also charge the active laptop at 90w and the inactive laptop at 45w and I never had a laptop go dead. CON’s: When I first connected the 129N to the laptops, both laptops displayed a CDROM drive. Startech tech support which is amazing did not know why this was happening and said I needed to send in some logs which I did not have time to do so I just hid the CDROM in device manager. The next issues was my logi webcam was sporadically fuzzy on calls using either the USB 2.0 or USB-A ports. Startech said some Logi webcams were buggy with their products and in absence of a Hardware Compatibility List (HAL) I purchased a Microsoft LifeCam Studio and had the same issue. The next issue I faced was with the Logi Craft Keyboard I purchased in 2019. If the Keyboard was withing 24 inches of the unifying receiver which had line of site the keyboard would work fine. If I moved it 27 inches out sometimes the keyboard would not respond and the signal light on the keyboard would flash. Its worth mentioning that the ethernet port on the 129N works great but it only supplies connectivity to the active computer so the offline computer will lose wired connectivity. Occasionally the 192N would not wake up one of the laptops and I would have to open the lid and close it. This never happened in my original configuration noted above. Conclusion: This a great device if you have two laptop, two monitors, and display port technology. I’m not sure how this would work with a desktop computer utilizing a high end graphics card because the video ports on the GPU would not be used.

I’ve been using this docking station with no issues for about 6 months. I had tried other setups hoping for the ability move between my home and work laptops without a lot of shuffling and re-plugging, but this was the one that worked. It’s easy to use and reliable, and the one time I was caught off-guard by a surprise switch as another reviewer reported, the person I was speaking with on Teams didn’t know anything had happened. It only took the push of a button to get me back where I’d been. I’d absolutely buy it again.

This device is a rarity in this field. It addresses a very common scenario -- two computers that need to share two external monitors and various peripherals. And it achieves that aim very well. It has all the necessary ports that can be shared by both computers -- Ethernet, extra USB 2.0, 3.0 and USB-C ports, speaker and mic connections -- and USB-C connections for the host computers, which also charge your laptops if you use straight USB-C to USB-C cables. The ONLY feature they failed to include is EDID emulation, which keeps the disconnected computer thinking it's still displaying on the external monitors in order to preserve application positions across the extended desktop. So if you've got your desktop extended across two screens with multiple applications -- with some on one screen, and some on the other -- when you switch to the other laptop, you'll hear the disconnection/reconnection tones and all your applications will be sent over to the main display (identified as #1) by your computer. When you switch back to it later, you'll have to move all your applications around again. At this price point, this is a disappointment, as I would expect it to address such a basic issue when it comes to using two external monitors. If it was a matter of cost, I think anyone that's willing to pay this kind of money for a KVM switch/dock would gladly pay a bit more and just have it deliver the extra feature. As for what makes this device a rarity, it's that it has a nice "symmetrical" setup -- meaning one type of input (USB-C) for the hosts and one type of output (DisplayPort), plus fully shared connections (Ethernet, USB). Other similar KVM docks have a mish-mosh of ports (e.g., one display with HDMI, the other DP), some don't share the Ethernet connection, some don't share all the USB ports, some provide charging on only one USB-C port, etc. So in this sense, this device is a masterpiece. There is currently no device that can be added to this setup to provide EDID emulation, so we'll have to live with it. However, they have a free software that allows your device to rearrange your applications to the positions they were when you switch back to that machine. But it still has to go through the reconnection and rearrangement, so that takes a few seconds. I would rate it 5 stars otherwise, but because of it lacks emulation, I can only give it 4.

I purchased this KVM because I have two laptops (Dell XPS): one for work (Ubuntu linux) and one for personal (Windows). I switch between these quite often. My previous KVM did not work nearly as well as this one and I thought I was going to have trouble with this one as the video did not work with Linux out of the box. I contacted support and they got back to me on the first business day which is really awesome. I installed a new package and drivers for linux and everything works great. My windows laptop did not have any issues whatsoever.
