I'm looking for a USB to HDMI 1080p adapter (only, no other ports needed) that supports DDC/CI, which is the ability to adjust a connected monitor's settings, like Brightness and Contrast from a PC, instead of fiddling with a monitor's physical control buttons.

For example, using this Windows program:
Nirsoft Control My Monitor
http://www.nirsoft.net/utils/control_my_monitor.html

I've tried all these adapters, but none of them work with Nirsoft Control My Monitor.

WAVLINK USB 3.0 to HDMI Display Adapter with DisplayLink Chipset DL5500

Nekteck USB 3.0 to HDMI 4K UHD with DisplayLink DL5500

USB 3.0 to HDMI Adapter with Fresco Logic driver

Interestingly, a very old VillageTronic USB to HDMI adapter works with Nirsoft Control My Monitor, but that adapters maximum resolution is 1280x1024. :-(

For those of you with USB to HDMI adapters, would you consider running the Nirsoft Control My Monitor to check if it's able to access your monitor, please? If a red colored error code appears at the bottom of the Nirsoft program, it was unable to access the monitor.

Thanks!

Answering my own question... I tried one more adapter and found gold! This USB 3.0 to HDMI adapter supports DDC/IC!!!

CableCreation USB 3.0 to HDMI Adapter (DisplayLink), USB External Display Graphics Adapter Compatible with Windows 10 / 8/ 8.1/ 7/ Vista/ XP, Black
Has Displaylink DL3500 Chipset
$39.99

And, it doesn't cause a horrific amount of RF interference that other USB to HDMI adapters emit that interferes with Bluetooth devices, like slowing down mouse movements.
