CableCreation USB-C to VGA + USB 3.0 + USB 3.1 Type C Adapter

I bought this adapter from to connect a HP Pavilion 21.5-Inch IPS LED HDMI VGA Monitor to my 2017 iMac, to serve as a second monitor.

While there were other cables/adapters that might have been compatible, I bought the CableCreation USB-C to VGA + USB 3.0 + USB 3.1 Type C Adapter specifically because it listed that it was compatible with the 2017 iMac.

Connecting the VGA cable to the adapter, and the adapter to the iMac, was all straight-forward.

After connecting the adapter to the iMac USB 3 port, the HP Pavilion monitor immediately displayed the iMac desktop.

I did encounter one problem. Though both monitors worked, there was an error message in the top right-hand corner of the iMac similar to:

error – USB Accessories Disabled, Unplug the accessory using too much power to re-enable USB devices

The above may be pretty close to the exact error message, but I did not save the message after conducting an internet search.

After conducting an internet search, I read on an Apple forum that an SMC reset should solve the problem. I then followed the instructions under How to reset the SMC on Mac desktop computers, at the following url.

That got rid of the error message.

I wanted this two-monitor setup primarily so I could use the HP Pavilion monitor to display the Open Broadcaster Software (OBS) application, with a window on the iMac monitor serving as a source.

The CableCreation USB-C to VGA + USB 3.0 + USB 3.1 Type C Adapter allowed me to do this, so I am initially giving it a 5 star rating.

If anything changes, I will update this review.
