Just got a new TV.. Thinking of swapping it..

[nerdboyrockstar]

So my birthday was last week and as a gift my mom bought me a 42" LG 1080p 120hz set from Best Buy.

This is my first LCD TV.. I think the picture is noticeable improvement over what I had before, especially watching blu but my mom doesn't think it looks good enough. Keep in mind though that she has a Pioneer Elite Plasma.. but even so, she says it doesn't look as good as the ones at Best Buy.

She says the image looks soft/fuzzy.. and I won't lie, I do notice it sometimes as well as some grain/saturation/fuzziness depending on what I'm looking at..

Now since she dropped the nearly $2,000, she says I should swap it.. but for what? Is there something I should do to the TV first? Or is she constantly going to be disappointed with Plasma vs LCD?
