I'm having an ongoing problem with my Samsung 955df monitor. When the monitor has been off, in standby or on screen saver for awhile and I start it up the picture is great. Within minutes it slowly starts to degrade (goes out of focus)until it's barely readable. This monitor has 2 focus controls (edge and middle) and I've tried adjusting both after it is warmed up (1 hour or so), to no avail. I can get 1 area focused, at the expense of the others (left, middle or right). I've tried different refresh rates and resolutions with no results. I'm wondering if overheating may be causing this...the unit has never been opened and the environment here is pretty dusty (I regularly blow out my tower with dry aerosol). Or am I drawing at straws with that idea?
