HP Recommended
Product: Envy 27
Operating System: macOS 10.12 Sierra

When connecting retina Macbook Pro (2016) computers to the HP Envy 27 via USB-C, I receive the following message:

 

USB-C

Caution - An unqualitifed USB-C cable 
has been detected. 
Please use a qualified HP USB-C cable 
supported by this monitor to ensure the 
best performance.

 

(Please see the attached image for the error message as displayed on the screen.)


This message appears when using the USB-C cable supplied by HP with the monitor. We have tried this with different computers, and the same message appears. These computers are running macOS Sierra 10.12.5 and 10.12.6. This monitor previously worked with these computers without issue. We have attempted to remedy this by changing the port that the monitor is connected to, cycling the power to both the monitor and rebooting the computers, and connecting the monitor both with its power on and power off.

 

HDMI still displays as expected.

 

Searching the web, this error appears to be experienced by at least a handful of other people. (see https://www.amazon.com/gp/customer-reviews/R29JEGTBYKK1XZ/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B01N3Y..., http://fado.vn/us/dp/B01N3YVA0P/ref=twister_dp_update?ie=UTF8&psc=1, https://9to5mac.com/2017/02/06/affordable-macbook-pro-display-hp-envy-4k-usb-c/).

 

How can this be remedied?

 

Thanks,

shane.
