Wow, I've never heard of this....I have a gateway flat panel and have never had a problem w/that. If I knew it was there, my eyes would fixate on it and it would drive me crazy! That's just the way I am.....poor "hub", I had a picture on the wall that I thought was not the same distance away from my mantel as the other, it drove me insane until he said, I'll show you.....whipped out his measuring tape and hung his head........."I cannot BELIEVE you could see that this was just 8/16 of an inch off" he fixed it and I was all better LOL!
If your computer/monitor is new enough, can you swap it for another?
