My apologies if this post is in the wrong section.
I have a macbook pro 13-inch early 2011 connected to my new Dell 34-inch u3415w screen via a MDP to displayport cable. I have USB peripherals connected to the downstream USB ports on my Dell monitor. My computer is able to display the 3440x1440 resolution just fine.
My question is, why is my macbook unable to recognize the USB peripherals? I thought displayport can carry data.
A quick google search revealed that my early 2011 macbook pro has thunderbolt 1 technology, and it seems like displayport 1.2 standards was first incorporated into thunderbolt 2 technology. My only guess is that my computer's lack of displayport 1.2 is the reason my computer can't recognize the USB peripherals connected downstream to the monitor. Before my Dell monitor, I used an LG 34UM95 (which uses thunderbolt, not displayport 1.2), and my computer was able to recognize USB peripherals connected downstream to the LG.
