Black horizontal lines on my 23er monitor

[allyf5]

Hello, there are black horizontal lines that just appeared at the bottom of my 23er monitor screen. I tried disconnecting the monitor, unplugging and replugging it. No luck.

Any help is highly appreciated.

@allyf5 -- do you see the lines when the monitor is NOT connected to any computer?

Do you see the lines when the monitor is connected to a different computer?

The most-likely cause is a partial failure of the electronics inside the monitor, "dis-drawing" some of the screen. Maybe, if you can find a "TV technician", they can make a "board-level" repair on the circuit-board inside the monitor. Get an estimate, and compare to the cost of replacing the monitor.

If the monitor is less than 12 months old, contact HP Support to exercise the HP Warranty, to get it repaired/replaced.
