I have two PCs with Windows 10 OS and both have Kaspersky Total Security protection. A Dell displays video perfectly. A Sony Vaio has issues. When launching Slingbox, the add displays perfectly. Once the add finishes, the left half of the screen is perfect but the right half is solid colors with no definition. Video like CBS.com, Watch ESPN, etc. is perfect. But other streaming video, some ads, some video in web pages is similarly distorted so, it's not just the Slingbox video. The distortion occurs in Google, IE, Edge and Firefox. I haven't been able to identify the source of the problem.
