Everyone should own a calibration disc. Either Avia or Digital Video Essentials. It maximizes your HDTV purchase.
Avia
Digital Video Essentials
Absolutely. And all you really need is a DVD player to calibrate a TV properly. I use Avia, personally.
I wasn't referring to blurring or lag in RB2. I was just referencing that wireless guitar as a pretty good way to measure your video/audio lag. The new guitar I guess has a microphone and image sensor, so you just hold it up to the TV during the calibration and it will adjust the game accordingly. I've got a plasma, my buddy has an LCD. If I play Rock Band or Guitar Hero at his house, I am late on all the notes until I can adjust my timing. When he plays at my house, he is early on all the notes. That's because of the input lag difference between plasma and LCD. If you've got that RB2 wireless Fender Stratocaster, do the calibration and see what the lag calibration ends up being. I'd be curious to see how much it adjusts.
Once you are used to the LCD, you likely won't notice the blur or the lag when playing games. Just like using a slower internet connection. After a while, you just adjust to it. Problem is, I went from a rear projection TV to a plasma. Before that, I did a ton of FPS and gaming in general on the PC. So, every time I watch fast moving movies or sports on an LCD, I can see the motion blur. When I play games on LCDs, as opposed to plasmas, I can tell there's more latency present. Even on the best TVs. Newer models have improved the motion blur with better response times, but the technology they use to do so, adds input lag to the TV. So you can't have your cake and eat it too, so to speak. The motion blur is inherent to the LCD technology. Plasma response time is in microseconds. LCD is in milliseconds. The human eye can perceive visual changes at 4ms. Even the best LCDs on the market cannot turn off a pixel and turn on another pixel fast enough to avoid this. The bigger the TV, the more noticeable this is. Plasma technology, whether people care to admit it or not, is just better, because of human visual perception. There's a lot of information out there if you are interested in looking. If plasma manufacturers deployed this information in their marketing, they would likely be much more popular than LCDs. It is all physiological, and it explains why it is intolerable to some people(like me), and some people don't even notice it.
