Review on 🖥️ TESmart HDMI Dual Monitor KVM Switch 4 HDMI PCs + 2 HDMI Monitors - 4K@60Hz, Cascade Quad Monitor, HDR 10, HDCP 2.2 (Black) by Kevin Jacobson

I took a chance with this KVM because it says it supports two 4k60hz displays but doesn't specifically say it supports ultrawide displays. However, it works well with a Gigabyte G34WQC 3440 x 1440 panel, albeit limited to 100Hz, and a Dell S2716DGR 2560 x 1440 monitor at 60Hz (Dell only supports 60Hz over HDMI, so it's not KVM that is the display restricted). The USB ports also work great, switching the Blue Yeti's mouse, keyboard and microphone between all four computers - a gaming PC, a MacOS NUC8i5BEH, a Linux computer and a real Macbook Pro. It took a while to get started compared to my previous CKL KVM, but I'm not sure why. Now that it works, it works great. The only random issue that pops up is that my left monitor sometimes doesn't see an incoming signal, but it did with my old KVM too, so it's probably not a KVM issue. The cables also look a lot better than the ones that came with their old CKL KVM. In general I am very satisfied with the purchase. It does what it says on the tin, exactly what I wanted.
