RE: TB16 constant flicker at 60hz (XPS13 & 4K Dell P2715Q)
Thank you! I only had a mini-DP to DP cable so I tried reversing it and that didn't work. I tried a mini-DP to mini-DP cable as well and had the same problem. I bought a standard-size DP to DP cable and haven't had a single problem with flickering all day. I don't know if the problem lies in the dock or the monitor but using a full size Display Port cable is the only way to currently use this setup at 60hz.
