Display turns off/on randomly with FreeSync enabled

[Lisk13]

I have an issue while gaming with FreeSync enabled, as the display just turns off for a second or two and then on again w/o any error messages. All the processes, sounds are continuing to work fine when it happens. I've tested about 10 games which runs with different FPS count and result is same.I tried to connect it by a 3 different HDMI cables (have read the other topic with same issue but DP cable using, so i guess it's not a connection problem), reinstalled drivers to a latest revision for my AMD RX 480 (tried both recommended and optional) using DDU.

With a second monitor which also supports FreeSync feature, but limited at 75Hz, all the games runs fine.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

I've replaced complete HDMI cable to a DisplayPort about two weeks ago, and the black screens is no longer happened. Still testing, but it seems like the issue is gone.

Thank you!
