When i switch on and when i am using the computer my monitor shows a wave like appearance in the background.can you help me to solve this problem.
Hello
I had that problem last mounth. If your warranty didn't run out give your lcd to the service. They changed power card of my lcd and then problem dissappeared. Checek your home voltage. They told me that high voltage could cause this problem.
Now fixing without repair:
open the main menu and increase brightness to %100. This is only the one way to lose backround wawe. The sound is so crazy but it only work when the brightness level at the top.
Hi,
"wavy" display or in the background is indicative of
60 Hz AC component riding in with the video signal. Pls check that all
connectors are snug and fit to where they are connected. It would do no
harm to try to remove and reinstall/reconnect all cables. Additionally,
try plugging in the monitor into a different socket/AC mains. Further,
you may want to try and check your cable for any stray shielding or
anything out of the ordinary.
Other than the above, could not
suggest more easy user action. The alternatives are to try a different
monitor to determine if it is the computer's video card or the ViewSonic VA1912w
that is in question; or try the ViewSonic VA1912w in another PC. It should be
mentioned that some household appliances can also cause AC interference
such as florescent lamps, wireless phones or even an electric clock.
Of course you can also try increasing your PC's Screen refresh Rate to anything other than 60Hz.
Technically, it may be the power supply of the ViewSonic VA1912w that is the issue. It is possible that a filter capacitor wold need replacement.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
