RE: TB16 constant flicker at 60hz (XPS13 & 4K Dell P2715Q)


this is not really a TB16 issue. I use the TB16 with following devices:

Dell XPS 9350 (Developer Edition > Intel Wireless)

Lenovo P50

Lenovo P51

It works fine with Lenovo using 1x4K + 1x2K Display. With the Dell device i get constant dropouts/flickering.

I get the same issue using USB-C > DP or USB-C > HDMI Adapters on the Dell. Looks like the USB-C Port have trouble keeping up. There is some known issue involving WLAN RX Power and the USB-C Port.
