I have used a number of different VGA- and DVI-based KVMs from IOGear, D-LINK and Syba, but I have no experience with HDMI-based KVMs. I prefer Syba's solutions, but their only HDMI-based solution only has three useable ports (the fourth is only for Smart Phone connection); they do not have an 8-port version. The HDMI solutions in the NUCs can be finicky; you need to make sure that the switch you select has support for HDMI 1.4. I do know that using a DVI-based switch and HDMI-to-DVI (or DP-to-DVI) adapters works just great with all NUCs (and I have tested every NUC model).
Hope this helps,

Intel has not tested any KVM yet. My best suggestion is verify is you have the latest BIOS, chipset, Management Engine and graphics driver version from the page below:
In my original response, I said that I had no experience with HDMI-based KVMs. Well, I do now...
I purchased a Zagall 4x1 USB HDMI KVM Switch (available for US$76 here: Amazon.com: Zagall 4x1 USB HDMI KVM Switch). There were a number of negative reviews for this product but they didn't read right (sounded to me more like user error than anything else), so I took a chance. I am glad I did. It works perfectly.
So far, I have tested it with various combinations of these devices:
- An Intel DH77DF-based desktop PC running Windows 7 and using on-board video.
- An Intel DZ68BC-based desktop PC running Windows 7 and using HDMI output from ATI graphics card.
- An Intel STCK2M3W64CC Compute Stick running Windows 10.
- An Intel BOXSTK1AW32SC Compute Stick running Windows 10 (32-bit).
- An Intel NUC5PGYH NUC running Windows 10.
- An Intel NUC6i5SYH NUC running Windows 7.
I will try with other NUC models as time allows.
With each PC, the only thing I had to do was select the HDMI audio as the default playback device in Windows. The KVM's embedded USB audio device, which supports front panel headphone and microphone jacks, was selected by default (because the USB discovery ran after the monitor detection). Other than that, it was plug-and-play.
I have this KVM connected to a Seiki SE22FE01 TV. This TV has a bug in its HDMI input handling and will not wake automatically if the TV goes into a low power state. Bottom line, I cannot tell you if this feature will work properly with other TVs.
I also have a Logitech G15 Gaming keyboard connected to the KVM and have the software for it installed on all PCs. It too is working flawlessly (I have an IOGear KVM that didn't do so well with this keyboard connected).
Hope this helps,
P.S. The unit comes with cables for all 4 ports, but you have to provide your own HDMI cable for the TV.
