HP 24es 23,8-inch monitor isn't working anymore, as you can see

the monitor is still under waranty. Does anybody know what the problem is and how we can fix it?

@elitebook500G3 That looks like it could be an issue with the graphics card on the computer, the monitor is connected to, perhaps, you should connect your monitor to an alternate computer and check if that works fine.

• If it works fine on the Alternate monitor, it's a hardware issue with the desktop/laptop its connected to,
• However, if it doesn't work on it either, this could be an issue with this particular monitor.

Thanks for your help but there is a problem with my monitor itself. The lines on the screen remain even if the screen is unplugged.

Do you now what the problem could be and how it can be fixed?
