My 25er HP display monitor is not turning on. Everything upd... - HP Support Community

I am having trouble turning my monitor on. When I hit the power button, the light doesn't come on, nothing happens. I don't know if I need a power supply cable for my monitor but I need help figuring out what to do and how to turn it back on so I can do my college work. I used it last semester, but I don't recall using a power supply cable at all in order to keep the monitor on. Please help!

Hello
I do not understand everything you indicate
You mention the power cable.
When you plug in a display, you have the cable which is connected to the hdmi dvi vga graphics card.
but for it to be powered, you either have a cable that connects to the screen, or it is a small transformer, power supply box!
You must therefore have the screen plugged in one way or another into an electrical outlet!
if not, it cannot turn on

I have an HDMI cable connected to the monitor from my laptop. I can see in my settings that my laptop recognizes the display but it says "Display 2 not active".

My 25er HP display monitor is not turning on. Everything updated but I don't know what's wrong.
