Well, the root reason and a solution was presented by Kristoffe Brodeur: It"s the video demo mode in Catalyst video driver settings. Kristoffe wrote:
I have noticed that with Win7 after playing through the Catalyst settings in "Avivio video " you will certainly view "all settings ", then scroll all the way down and tbelow will be a fieldcollection called "video demo mode ".If you have actually "video demo mode " settings "permit demo mode " check noted via break-up display mode as an choice, you will certainly view a red line. To remove it, ssuggest uncheck "enable demo mode ", push "apply " and then close with "ok ".periodically, you may see a green line, which is a driver for the video card, FFDSHOW or some other codec messed up, or the video card can be damaged, not pushed in all of the means in a pci, agp, or pci-e slot.
A plain but old working solution. I thought, the case would certainly have been solved – yet newly I was alerted from MS Answers about new posts. Obviously new ADM Radeon settings are permitting demo mode aacquire. Here is a user write-up from 2015:
I entered my AMD Radeon Settings application and also schosen the tab "Video". Up in the top, best, corner, sure sufficient, there is a setting for demo. Mine was set to "Demo On". When I adjusted it to "Demo OFF", the red line disshowed up. I just upgraded my AMD chauffeurs to this latest variation and then noticed the difficulty. Apparently, the "Demo" was on by default bereason I never before readjusted any kind of settings. Thanks you for the reminder. Fixed my difficulty.
Anvarious other user expect the mode has been collection throughout driver update.
Yep – fixed my problem by going right into Radeon settings and turning off demo mode. Must have actually been turned on with the last driver updates.
Also in April and July 2016 some customers are reporting this issue for Catalyst or Radeon Settings. One user delivers a hint, why some users are facing this issue.
