anyone know any good DisplayPort KVMs that support 144hz 3840x1600?
@tupper i wish you luck, if you do find one most will be 60hz supported as listed, but you may have more luck looking for a display port matrix, those are usually enterprise/corporate, used to send video to any combo of outputs

searching is NxY (so 2inputs to any 2 outputs)

i have done this search for our company's CIO as he works from home and wanted a single button press from work computer to home.
And i have also setup conference rooms where we used hdmi matrix's to support 3 monitors and a projector depending on where people sit
@tupper i forgot level1techs make this type of hardware, they might get very close to what you are looking for
