Solution
Turn on the monitor and check that the monitor light is on.
Try a different monitor.
Check the cable connection from the monitor to the computer
and to the electrical outlet.
Press any key or click the mouse button and, if set, type your
password.

Be sure that the monitor can accept the same horizontal scan
rate as the resolution chosen.
Press the power button to resume from standby mode.
CAUTION: When attempting to resume from standby mode,
do not hold down the power button for more than four seconds.
Otherwise, the computer will shut down and you will lose any
unsaved data.
If the computer system has both an integrated graphics
connector and an add-in graphics card connector, plug the
monitor cable into the graphics card connector on the back of
the computer.
1. In the Control Panel, under Appearance and
Personalization, under Display, select Adjust screen
resolution.
2. Use the sliding control to reset the resolution.
Use the monitor's on-screen menu controls to select the input
that is being driven by the system. Refer to the monitor's user
documentation for more information on the on-screen controls
and settings.
Solution
The integrated graphics can be enabled in Computer Setup if
a PCI or PCI Express x1 graphics card is installed, but it cannot
be enabled if there is a graphics card in the PCI Express x16
slot.
On systems with AMD integrated graphics, install an AMD PCI
Express x16 graphics card and enable the integrated graphics
in Computer Setup.
