Excellent study in the Displaymate source link, Charles.

It's nice to see scientific studies that convince me to spend less money.

I would assume this is for LCD monitors as well as TVs...an LCD is an LCD. Interesting. I'd like to see more on how they tested, and if some of the study people considered themselves susceptible to seeing motion blur.

I may have missed it, as I read the report fairly quick, but I did not see where they mention 24 fps film sources or discuss the psychological Sample and Hold Effect that affects some folks more than others. The study looks geared specifically towards 60 fps video, which will always appear “smoother” than film. They also avoided projectors and LCOS / Dila variant LCD technologies. Sony’s dark frame insertion is unique to anything else on the market, and the majority of user reports for this process are favorable as it directly relates to SHE.

A year ago I had no idea what motion blur was, why it existed, and if I was sensitive to it. I was in a clueless state of bliss with my LCD projector. Then I started reading about it and now I’m sensitive to it…….. But now that I know it does exist, and why, I’m screwed. I see it all the time and it drives me nuts. I will most likely move to DLP and do my best to convince myself that rainbows don’t bother me.

In the source material they are more specific that they are talking only about the response time of the LCDs themselves and not the 24 fps up-conversion induced problems.

I can say w/o a doubt the 24fps issue is real. Perhaps some people are more effected than other and I must be one of the. Watching 2001 on my new projector there are a couple of scenes where moving spaceships show motion judder as they move across the screen. Also while watching Aeon Flux there are several pans across close up objects the blur. By turning the frame creation mode up to 2 both the judder and blurring completely disappeared w/ limited effect on the PQ in only a few scenes. So anyone who says that the 24fps thing isn’t real I’m throwing the BS flag. Thankfully I don’t see rainbows on my DLP.

The 24fps thing isn't real, at least on the Pioneer Kuro plasmas. When fed a 24 fps signal, they go into 72 fps mode and display each frame 3 times, for a solid film-like appearance.

I’ve always like the pictures on plasmas. Got a line on any 134” diagonals for near $3,000.

Seriously I did look at getting a BMFP (Big somethin somethin Plasma) because it’s a straight shot in through my garage to my screen position. Unfortunately it would have cost almost as much as my house.

Here's a costs-as-much-as-a-house plasma. It's also only 103", but I like that it runs on 230 Volt, and ends up requiring 1550 Watts. I'm sure it's illegal or own or operate in the State of California.

A couple of years ago, there was a survey of delivered vertical resolution in which plasma was consistantly the best. I seem to remember that LCD was all over the place.

I ended up with RP as a compromise because it delivered excellent colour, resolution and minimal motion blur at a cost of thickness.

I wish they would hurry up already and figure out this OLED tech. before I need a new display.
