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.
