@m3th0dddm4nx, Welcome to HP Support Community!
Turn on the computer and complete the following steps:
Step 1: Check cable connections
If you can see the initial HP or Compaq logo screen but later lose the picture, you can skip to Step 2.
Otherwise, check the video cable connection on the back of the computer and on the monitor. Make sure that it is connected properly and the connecting screws are tight. Turn the monitor off and then back on again (while the computer is on) to see if an image appears.
Some Flat Panel monitors have two similar power input connections placed side-by-side on the back of the monitor, which sometimes allows them to get confused for one another. One connector is used to supply power to the speakers with a separate power cord, while the other connector is used for the monitor's power adapter.
Ensure that you have the monitor power adapter cord plugged into the power connector and not the speaker connector.
After you have reconnected the power cord, turn on the monitor (while the computer is on) to see if an image appears. If there is still no image, continue to the Next Step.
Step 2: Resetting the monitor
At first setup, or under certain signal conditions, the monitor may not be able to switch to a new display resolution. Do NOT shut down or restart the computer. Instead, perform the following steps:
-
Turn off the monitor using the Power button on the front.
-
If the Power button does not respond, unplug the power cord from the back of the monitor and wait five seconds.
-
Plug the power cord back in.
You should see the image from the computer on the screen.
