The message is the only item that displays on the screen
After turning on the computer, the only thing appearing on the monitor is a message about no
signal or sleep. Startup screens and Windows screens are not shown.
When this happens, the monitor is not detecting an valid video signal from the computer.
Perform the following steps until a picture is displayed on the monitor:
1. Make sure the computer or device that is connected to the monitor is using the correct
video output source.
If you are trying to view video from a set-top box, DVD player or similar device, use its
menu system to set the proper video output channel so that it matches the video
connection are using. For example, if the monitor is connected to a satellite receiver via a
second HDMI connection on the back of the receiver, select HDMI-2 (or similar) using
the remote control for the receiver.
2. If the monitor has an input or source button, press it.
On some monitors, the video input or source selection can be found in the onscreen menu
system. If so, press the Menu button on the monitor and use the front panel buttons to
select Switch Video Input.
3. Connect the monitor to another computer and turn the computer on. See what happens:
o If the monitor correctly displays an image from another computer, the monitor
works and the video on the original computer is incompatible, faulty, or sending
too weak of a video signal. Make sure the computer is truly sending a display
resolution that is compatible with a monitor and not set to display video for a TV.
If necessary, service the computer to fix the video hardware or video drivers on
the computer. If you have an HP or Compaq computer, see the Contact HP page
to find service.
o If the monitor remains blank when it is connected to another computer, the
monitor might be damaged and should be repaired or replaced. See the Contact
HP page to find service.
