No picture The signal cable should be properly connected to the

Try disconnecting the video cable from the display and
connecting to another display if available to confirm the
presence of proper video.
Make sure the power is connected to the proper AC source.
Make sure the resolution mode is supported by the display

Confirm that the video cable is not defective.
Image persistence
Image persistence occurs when a ghost of an image remains
on the screen after the screen image has been changed.
Unlike a CRT monitor, an LCD monitor’s image persistence is
not permanent. To erase an image ghost, turn the monitor off
for several hours. What happens is that after extended
periods of operation the liquid crystals “set”. To avoid this
condition, install a screen saver program on the computer.
