Hello all,

I bought a new desktop computer and want to use the same 21' monitors I already employ for the (desktop) work computer we were given since working from home.


Besides the usual USB ports it should feature two DVI/HDMI ports for each desktop computer attached. The KVM switch should also support two 4k displays. Is there a model and/or manufacturer you can recommend?

I know this is not strictly Linux related (don't know how many issues to expect) but maybe some of you have a similar setup and can tell me about their experiences.


Many thanks

You won't generally get 4K over DVI ('but some things show specs for it' - find a monitor that isn't an IBM T220-clone that takes 4K/9MP over DVI and we can talk). Dual-link DVI KVMs are a bit esoteric, but I know Belkin makes a few (I have one of these and it works well: https://www.belkin.com/us/p/P-F1DN104B-3/) - they can get really pricey though, and from browsing their website they do offer 'dual view' (two monitor) models as well: https://www.belkin.com/us/p/P-F1DN104F-3/

For HDMI you're probably better off finding an 'HDMI matrix' that accepts HDMI 2.0, which will exist, but will also likely be pricey (some post-script web searching looks like around $100 US), and then adding a USB switch for the peripherals. (like this: https://www.iogear.com/product/GUS402)

The other other option is if the monitors have >1 input (which is likely), use their on-board switching facility (which will also let you 'split' the monitors between two machines), and just get a USB switch for the peripherals.
