Anybody know why LCD's suffer from motion blur?

Plasmas have different rendering techniques. Plasmas, and DLPs, use a form of pulse modulation to express grey levels. My guess is PWM or PNM technique can better simulate the impulse/persistance feature of an analog CRT.

If this is the case, then when I buy my 52" LCD in a month or so, should I not spend the extra money for a 120Hz Samsung or Sony, and just buy the 60 Hz model?

So if it's only a perception within the brain, does that mean that it doesn't matter how large the LCD screen is? I mean, according to that theory, it shouldn't make a difference in how large the screen is, right? Just a thought: Is this a form of propaganda in that the large TV manufacturers are telling us its in our brain, in order to degrade the value of a faster response time? It might be far fetched, but I do wonder...

I would still get 120Hz if I were buying an LCD. But I won't.
This seems to be a very serious drawback. The two main failures of LCDs to-date have been poor black levels and motion blur. Future generations of LCDs will have greatly improved black levels by using locally dimmable backlighting; but apparently motion blurr is irremediably inherent to this type of display technology.

I agree with Ttone, it is much more noticeable on larger screens. This is not propaganda. If anything, the manufacturers may be exaggerating the benefits of faster response/refresh rates.

Well then, instead of an large screen LCD with the motion blur should I be considering a plasma? I had ruled it out due to all the windows in my den (glare problems) where I would hang it.

According to an engineer at Panasonic. Plasma has a response time of 2ms. DLP is even faster. LCD is old technology with limitations. Also when a manufacture is rating response time is that full on full off or Grey to Grey?

IN my opinion Pioneer makes the best flat screen with Panasonic second. Most of the Panasonic Plasmas use a anti glare screen. IN my opinion unless you are in direct light brightness and glare are not issues. Plasma gives you the best color, contrast and is free from motion blur.
