Connected Thinkpad to external AOC monitor by cable. Both are older equipment. No sign of life on AOC. Yikes!. Right clicked laptop screen. Selected “display settings”. “multiple displays” box at bottom at first showed no options to pick from. Did a bunch of and combo of … powered AOC off/on, disconnected/reconnected cable, powered down laptop and up. At first only got “Extend display” option, later got multi display options showing up to select from. All good now. Shipping cost more than the part. Ouch. But it arrived quick. Quality of cable good and price is right.

as describe, work with my mac and my surface dock

Exactly what I was looking for and it works fine.

Fonctionne très bien
