My sister in law has a Rosewill and she loves it. I played Unreal Tournament and Quake III without any ghosting. It doesn't have ghosting with DVD's. Like you said, Acer is not very well know for great products, but on the other hand, who the heck is Rosewill. I am trying to find out the answer to your questions, hopefully through this post.
