Plasma + Video Games issue

[aimforsilence]

Hey so I have a Panasonic G25 50" Plasma tv. I've already broken it in and all that and everything is good. Except for one problem. I enjoy video games... Most of the time games don't effect the Display as most recent games have transparent HUDS or the HUD disappears after a short while. But lately I've been playing Dragon Age: Origins.. which unfortunately has a static HUD. It just stays there all the time. And this has led to Image retention. Though I've used a dvd I have to remove the said retention and it did indeed work. My question is this. Would turning the Pixel shift from auto to 1 minute help solve this problem? or is there any other idea i've looked past? Or perhaps I should just save up for a Gaming LED Screen instead? Thanks in advance people
