Here's another good demo of LCD motion blur:
Are you aware of the beta test of the brand new Blur Busters UFO Motion Tests website?
in a supported web browser
that can do VSYNC (e.g. Google Chrome or IE10+, running on a recent GPU)
Several motion tests are:www.testufo.com/#test=framerates
....... Framerate comparisonwww.testufo.com/#test=photo
.............. Moving photowww.testufo.com/#test=eyetracking
...... Demo of sample-and-hold blur -- eye tracking based motion blurwww.testufo.com/#test=blackframes
...... Demo of black frame insertion
The above links even works on newer iPad's as it is running a supported web browser (good way to show off).
Feel free to contact me by PM, if you'd like to discuss improvements to motion tests, for reviewer purposes (e.g. addition of moving test patterns).
That's not to say plasma and DLP images are perfect... both have their issues. But motion blur bugs a lot of people, including me. So it's nice to have tech options where motion blur is more or less a non-issue.
Are you aware of the recent computer gaming community's buzz around LightBoost strobe backlight LCD computer monitors that have less motion blur than plasmas? (e.g. 60Hz vs 120Hz vs LightBoost
, as well as the media/blogger coverage
about LightBoost?) These displays achieve actual true measurable MPRT's of 1.4ms, and these outperform scanning backlights
which historically has the backlight diffusion problem limiting the degree of motion blur reduction.
From measurements made, they are the first consumer LCD's already on the market, to finally exceed the motion resolution of certain CRT computer monitors, even according to oscilloscope measurements. Some former Sony FW900 CRT users have remarked that it has clearer motion than their Sony CRT (during LightBoost=10%) since 1.4ms strobes is faster than the medium-persistence CRT phosphor found on their FW900 CRT. That said, the color quality of a properly calibrated FW900 CRT is vastly superior, just that the LCD motion blur monster has finally been slayed in certain strobe-backlight LCD displays. Sony's new "Motionflow Impulse" (interpolation free) comes close, but doesn't perform as well as LightBoost. There are a bunch of "It's like a CRT" talk in various testimonials
and things like the customer reviews on amazon for VG248QE
(hit Control+F and find the word "lightboost").
On a 120Hz computer monitor with the LightBoost strobe backlight enabled (see list of 120Hz monitors
) and viewing TestUFO: Moving Photo at 1440 pixels/sec
-- this photo in motion, looks as sharp as stationary -- when you're using the LightBoost=10% setting. Motion clarity looks the same at all pixel speeds. Even the Panasonic VT50 plasma has more motion blur when viewing this moving photo at 1440 pixels/sec and faster (e.g. look at the windows in the castle at the top).
Mind you, computer gaming can be more demanding on motion blur than even sports broadcasts (this is when 1ms differences in motion blur start to become noticeable, as 1ms = 1 pixel motion blur at 1000 pixels/sec); some high end FPS gamers are quite picky on motion blur (sometimes moreso than color), buying expensive Geforce Titan's or 780's to achieve 120fps@120Hz gaming at 1920x1080 at computer-monitor-viewing distances.Edited by Mark Rejhon - 7/26/13 at 1:38pm
