Hi, When watching videos and movies the screen pixelates every so often. I have no idea how to change settings, or is there a problem with my laptop? All answers will be appreciated. Thanks in advance.  Cheers, Ian i7-3720QM  16GB Ram  Radeon HD 7970M  HD Graphics 4000

Hello Ian,

I would suggest a clean re-installation of the video drivers. That is, uninstalling and re-installing the video drivers. If not, please follow the steps:

Open Device Manager (Start -- Control Panel -- Device Manager).
Expand the tab for Display Adapters and right click the video card.
From the drop down menu, select “Uninstall”.
Ensure to check the box “Delete driver software for this device”.
Restart the computer.
Once the drivers are uninstalled, re-install the latest drivers from Dell Drivers and Downloads.
Restart the computer and check the functionality.

Hope this helps!
