My limiting factor from a video perspective at home is now my KVM. It is DVI based and supports up to 1920x1200 resolution. If I want to move to 4k I am going to need a replacement. Can anyone give a specific recommendation in terms of a KVM used successfully with higher (4k) resolutions, or even pointers to ones with these capabilities?

Requirements:

  • 4 Ports minimum
  • 3840 x 2160 Resolution (or better) Supported @60Hz
  • USB/Audio switching supported (USB2.0+ preferred)

Besides that I have no preference for HDMI or DisplayPort, and I am happy with being able to switch audio as stereo (i.e. it does not have to be carried over the same cable as the video).

As an example of something that comes close, but not quite close enough, this KVM from Startech will only support 4k resolutions at reduced frame rates.

The ATEN CS1924 fits your requirements:

  • 4-port DisplayPort KVMP Switch with USB 3.1 Gen1 hub and 2.1 surround sound audio

  • Superior video quality – 4K UHD (3840 x 2160 @ 60 Hz) and 4K DCI (4096 x 2160 @ 60 Hz)

  • DisplayPort 1.2 compliant, HDCP compliant

  • Supports HD audio through DisplayPort

  • Full bass response for high-quality 2.1 channel surround sound systems

  • DisplayPort Dual–Mode technology (DP++) supports HDMI and DVI signals via a DisplayPort-to-HDMI/DVI DP++ adapter

    going to accept this, though would be really nice to get some actual use feedback for something so pricey, thanks for the details – Adam Comerford Oct 5 '17 at 0:25
  • @AdamComerford, if you've now purchased it, it would be good to update here (or at least on Amazon or something) to say how well it worked out. – Wildcard Apr 4 '18 at 5:45

    The price for this is so high, especially when you add the fact that I would be looking to buy a 4K display (this KVM is more expensive than most displays at 750 euro) that I have had to give up on the idea of having a KVM in my new set up and settle for virtual solutions for managing my other machines – Adam Comerford Apr 4 '18 at 10:14
