My Sabrent TB4 KVM switch arrived today and here's my mini-review. I'm using it to switch betrween a Mac Studio and a Windows 11 PC. On the PC side, I have an MSI Z790 motherboard which has Thunderbolt 4 output and has a mini-Displayport input for passthrough from the GPU card, which in this case is a 4090. This is fairly standard for how PCs support Thunderbolt video. I was previously using a CableDeconn USB-C switch for the last year, which did an acceptable job except that it cannot pass through 40Mbps of video bandwidth and hence drops down to 20Mbs Displayport with DisplayStream Compression, which is not a big problem, but it was quite unreliable for passing through USB signals for accessing any of the built-in devices such as the camera or speakers, nor enable the use of the rest of the ports on the back of the monitor. I've been eagerly awaiting the availability of a true TB4 KVM switch for a while, and had been hoping SSI would find a US partner to distribute their KVM since they originaly previewed it back in 2021. Physically, the Sabrent KVM is essentially a Thunderbolt Hub with two host input ports and a pushbutton switch at the end of an extension cable, so that the box can be placed out of sight. I used a pair of Cable Matters TB4 cables to hook up the Mac to the KVM and the KVM to the Studio Display and everything worked as expected. The KVM does come with a pair of short Thunderbolt cables but those weren't going to reach for my desk setup. On connection, System Information shows a full TB4 40 Gb/s connection to the Studio Display and everything works great from speakers and camera. On the PC, it didn’t like the DisplayPort to USB-C cable I was using, which was just a simple one that did not have USB passthrough. Sabrent does claim that DisplayPort alt-mode cables on the PC or other devices do work with this switch, so I suspect that the cable needs to have USB in addition to the video signal, which the cable I used did not. I do have a Belkin cable somewhere in my cable box but didn't try it, opting instead to use the PC's Thunderbolt output, which worked fine. I have had issues with Thunderbolt video on PCs before, particularly with games as well as not getting a boot screen until Windows loads, so I've typically used DisplayPort to USB-C cables rather than Thunderbolt, even though the motherboard supports it, but this time around none of those issues has occured and everything I've tested seems to work so far. Intel Thunderbolt Control Center shows the KVM and the Apple Studio Display. I don't have the Bootcamp drivers installed so I'm not seeing the speakers or the camera on the PC side. I will try that and report back. Switching between the two displays takes quite a bit longer than the CableDeconn switch, which is not surprising since it's a substantially more complicated device, but I could see this being an issue for some. In any case, I use both the Mac and PC fairly regularly in my workflows as well as PC gaming, so I expect I'll find any issues reasonably quickly and will report back. I am not using it with any laptops, so I don't know about whether it charges the laptop that's not active. I do need to switch between the PC and Mac fairly regularly every day, so if this switch doesn't prove reliable or has compatibility issues, I should find them fairly quickly and report back, but so far so good.
