Just relating to this… we've got a situation at the office here were we have a rack full of servers. In the beginning it was VGA and PS/2, for which KVMs are widely available and cheap. We're now starting to get more and more machines that are HDMI/DisplayPort machines, with the annoying artefact of not being compatible with a VGA KVM. (I've tried various HDMI→VGA and DisplayPort→VGA adaptors with no luck.) We've since bought a DVI-I KVM, which works great. HOWEVER. The monitor is DVI-D/VGA. The KVM does no translation, and so when we switch over to one of the older VGA servers, we have to swap inputs on the monitor too. Unfortunately it seems monitors that have a true DVI-I input have been discontinued. We tried one splitter that supposedly brought a DVI-I cable out to DVI-D and VGA, but that seemingly missed some critical signals, so we got no picture on one of the ports. We also tried a DVI-I splitter box, meant to drive two monitors from the same source. We found it worked, if you reset the device before switching from an analogue to a digital source or vice versa. It assumed that the nature of the DVI signal (analogue or digital) never changed. Searching for these things online is an outright nightmare, because as far as Google and sellers is concerned, "DVI-D" == "DVI-A" == "DVI-I" == "DVI". They do not differentiate. A box that took DVI-I (in either form) and converted to DVI-D could work here, I've not seen such a device though. Heck, converting DVI-D to VGA would also work. Has anyone successfully used a KVM with a heterogeneous DVI-D/VGA environment? - -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iJ4EARMKAAYFAlVjkjMACgkQoCQEvFhlDPk6AAIAmQmfBe5y7xUHGM+a7MnRugPw VezgG97LKY9NKBIOAIiKs+dfne06NS0Jld0WsiEDAVFlk8b6Yb3JnzmCNaCAxwIA nyKFzD2sACUkMyMY2SFVz56QhX5hIS9AT/CZ655IpwGM4GB9hTimplSGu6g6OYfL 2XPrCnxOWCegPFaAdfhB3g== =cx3e -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
