my friend is having a problem, whenever he plays a video in any media player, it appears dark, but if he pauses it and opens the same video or a different one in a second media player, it plays normally. This happens with any filetype and any media player, doesn't matter which is opened first. He tried updating drivers and installing codecs, neither helped. anyway to fix this problem? Ive heard of people having similar problems but havn't found a solution.
