On-Screen Menus glitched

[limegreenicy]

I've had my monitor for about a year now, although recently the on-screen menus are glitching. It rapidly, on its own, switches the on-screen menus to locked and unlocked. It happens at random, and I tried to unplug/plug in again, re-install the drivers, etc but it keeps happening. I attached a video of what it looks like

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

• Step 1: Checking power
• Step 2: Displaying a built-in on-screen message
• Step 3: Fixing a bad video connection
• Step 4: Testing the video connection
• Step 5: Connecting the monitor to a different computer. Click here: https://support.hp.com/us-en/product/hp-value-27-inch-displays/3989902/model/16462325/document/c0129...  to complete the troubleshooting steps.
