I am in the market for a 52" LCD with 120 hz. I think I have narrowed it down to A650 or the w4100. I would choose hands down the a650 if it had a matte screen. This leads to my question. How bad is this sparkle problem on the 4100? I would only be using the tv to watch movies and sports. I do not play video games. Am I even going to notice the sparkles? If it really is not a problem, i think I will go with the 4100. Also, how bad is the cloudiness on this set? Will I notice a problem? Finally, I've heard that regular tv shows on Sony's are below average in picture quality. How does this model stack up with regards to the PQ on regular tv?
