\nI have a red line running vertically down the middle of the screen when playing movies with media player on windows 7.<\/p>\n
This happens with Windows media player and windows media player classic. I can us vlc and I do not get the red vertical line running down the screen. No matter what movie I play the line is there. But it does not appear until I actually push play. When I originally open the player I have a blank black screen. But once I push play the movie starts and the red line is there. Fast forward, rewind and pause, the line remains. How do I solve this problem?<\/p>\n<\/blockquote>\n
Well, the root cause and a solution was presented by Kristoffe Brodeur: It's the video demo mode<\/em> in Catalyst video driver settings. Kristoffe wrote:<\/p>\n\nI have noticed that with Win7 after playing with the Catalyst settings in 'Avivio video ' you will see 'all settings ', then scroll all the way down and there will be a fieldset named 'video demo mode '. <\/p>\n
\n- If you have 'video demo mode ' settings 'enable demo mode ' check marked with split screen mode as an option, you will see a red line. To remove it, simply uncheck 'enable demo mode ', press 'apply ' and then close with 'ok '.\n
- sometimes, you may see a green line, which is a driver for the video card, FFDSHOW <\/strong>or some other codec messed up, or the video card could be damaged, not pushed in all of the way in a pci, agp, or pci-e slot.<\/li>\n<\/ol>\n<\/blockquote>\n
A plain but old working solution. I thought, the case would have been solved \u2013 but recently I was alerted from MS Answers about new posts. Obviously new ADM Radeon settings are enabling demo mode again. Here is a user post from 2015:<\/p>\n
\nI went into my AMD Radeon Settings app and selected the tab \"Video\". Up in the top, right, corner, sure enough, there is a setting for demo. Mine was set to \"Demo On\". When I changed it to \"Demo OFF\", the red line disappeared. I just upgraded my AMD drivers to this latest version and then noticed the problem. Apparently, the \"Demo\" was on by default because I never changed any settings. Thanks you for the tip. Fixed my problem.<\/p>\n<\/blockquote>\n
Another user suppose the mode has been set during driver update. <\/p>\n
\nYep – solved my problem by going into Radeon settings and turning off demo mode. Must have been turned on with the last driver updates.<\/p>\n<\/blockquote>\n
Also in April and July 2016 some users are reporting this issue for Catalyst or Radeon Settings. One user delivers a hint, why some users are facing this issue.<\/p>\n
\nI had absolutely the same problem here and managed to find a solution for it. The option 'Tearing Test' was enabled for me. It seems like I pressed Ctrl+T<\/strong> combination and turned it on (wanted to create a new tab in a browser). You can also try to use this combination or go to View -> Renderer Settings -> Tearing Test and disable it.<\/p>\n<\/blockquote>\nMaybe it's the Ctrl+T shortcut key combination that was accidentally used during operation, that enabled demo mode. Someone wrote: Right click on RADEON settings on your system stray and under VIDEO PROFILE choose default. That shall solve the issue. <\/p>\n
VLC displays a green line<\/h3>\n
If users are seeing a green line during video playback in VLC player, there is also a settings solution, posted within the same MS Answers thread. Proceed the followings steps: <\/p>\n
Tools menu \u2013> Preferences \u2013> Video \u2013> Choose OpenGL under Output options \u2013> Restart VLC.
Tools menu -> Preferences -> Video -> Uncheck \"Accelerated Video Output (Overlay\") -> Restart VLC. <\/p>\n
That should solve the issue. <\/p>\n","protected":false},"excerpt":{"rendered":"
