Horizontal green line on HP All in one 24-dp0014 monitor

[dsz]

Just got a horizontal green line in my display for my HP all in one. Have check video driver. AMD driver was updated today. Tried to see if there was an updated driver. Did driver roll back, also did manual install of driver via amd's website and hp's. Have unplugged computer. Line still appears. It goes across screen about 2" from top. Not sure on how to open case to check cable to monitor. Not sure if it is refresh rate. Line shows up in BIOS and on boot screen, so more than likely it is not a driver issue. Not sure what else it would be.
