Linuxhelp _ Hardware Support _ Screen Flicker on Samsung Syncmaster @ 1920

Posted by: salesagility Jul 1 2011, 05:31 AM

I'm running Ubuntu 11.10 and just purchased a Samsung Syncmaster B2430.

If I try to run the screen resolution @ 1920, I get bad intermittent flickering in general use and it becomes unusable when viewing video

If I run @ 1240 - then everything is fine ... but that's not why I bought a 24" monitor.

When I run lspci -v this is what I get back for the video controller.

DO you have any suggestions about resolving this?

HDCP is Samsung's innovative way of protecting the integrity of the content is transmitted to the monitor through the DVI interface. This naturally delivers the highest resolution images, allowing you to enjoy 100% pure digital content, all the time. Have you tried to change the screen resolution?
