My samsung SyncMaster 204b monitor has developed a blue tint and in trying to change the resolution of the screen to see if that might help i have changed the resoltuion to 1280x720 which is way too large. Now when i go into personalise/dispaly settings and change the resolution on the sliding bar there is no option comes up to apply the changes. Any body know what I can do and also does it sound like my montor is failing.
