I have a Dell 5720 laptop with ubuntu 11.10. I can't connect to my Samsung LCD TV (over Marantz nr 1601 AV). Audio is ok but the pictures are displayed in two colours: green and lila !

Please send me a massage how can I fix this problem !

Thanks a lot.

I am very confused because I do not do anything however it comes(seldom) to the right colouring but only for a while(5minutes) and returns to the green-lila picture again when I do something else for example surfing with firefox or starting other programs ! The settings : resolutions of laptopscreenplay and TV are the same and I did not change the colour profile as well . My laptop screen is HD+ truebright (1600x900) and my TV SAmsung 1280x720 I have no idea what to do my HDMI connection to make right with the colours! How can I fix this situation to gain a stable colouring ?
