Hey all. I just wanted to post a bit of rarely used tech support here. Due to all of the normal daily wear on your graphics card and monitor, you should periodically purge the memory of you monitor and graphics card. If you use linux or Ubuntu, then you will not have that problems as they both have an automatic setting to do this for you, but those of us with Micro$uck need an extra utility to take care of this task.
It takes less than 10 seconds, so please give it a try. You will not be sorry, and you should show a marked happiness with the results.
