I just got a new PC at work (HP Z2 with Win10 x64), but for legacy product support I need to maintain a legacy machine (Dell Optiplex 9010) with Windows 7 x64 and x86 as well. IT was having issues getting drivers for Win7 x86 and x64 for the new PC, so dual-booting isn't an option. So I need some sort of switching mechanism to go back and fourth and use the same keyboard. mouse, and monitors.
Traditionally, I would assume I'd use a KVM switch and be done with it. But I was thinking it'd be cool to get new monitors with DisplayPort 1.2 so I can daisy-chain my monitors and reduce cable clutter. As it is, I'm an embedded software engineer, so I've got plenty of loose wires and my desk will go from clean to this in a day if I'm not careful. But then in doing my research, with the rise of USB 3.0 and whatnot, it seems like KVM switches are giving way to display over USB. I'm seeing DisplayLink thrown around as well. I'm not sure how much can really be displayed over USB and how many monitors it'll really support and if I'm still limited by (or dependent on) my graphics card at all.
I'm not opposed to hardware upgrades (monitors, graphics card, etc). I actually need to replace one of my monitors, so I may as well replace both and get matching ones, I currently have two Dell P2411H monitors. The New PC has a NVIDIA Quadro P400 inside, old one has an AMD Radeon HD7570 (which I'm not opposed to upgrading if needed). But now I'm even seeing that DisplayLink operates over plain old USB2.0, I was thinking I needed to add a USB 3.0 card to the old PC to make it work.
I'm not doing anything graphics-intensive, I don't need 8K video and a monster graphics card and whatnot. Mostly trying to reduce cable-clutter as much as possible. Any help is appreciated.
