I'm not sure I would recommend using a plasma for gaming. While the motion would be great, the risk factor for burn in on static images is pretty significant. Now, if you're willing to take that risk, more power to you.
I can't quantify scenarios, but most driving games have a static RPM indicator, Guitar hero has the Rock Meter, and many games have similar non-moving graphics that will affect long term gameplay. Last year's models suggested no more than 5% static images per viewing time each week.
Now, if you want to drop your brightness, contrast and other settings to lower than normal levels, you may delay image retention (temporary) or actual burn-in (permanent), however it may be - and is likely - inevitable if you're going to use it strictly, or mostly for gaming.
5% of the viewing time per week is the recommendation. Does that help?
I just came across this panel on amazon and was wondering if anyone had some eyes-on impressions to share. I'm a gamer, and while I know plasmas aren't generally the best fit for gaming, the price point is just insane. With that in mind though, I'd like to know what the burn in risk would be on a newly manufactured plasma such as this one, or if you all have any other suggestions in this price range. Any help will be greatly appreciated.
