Anyone seen the new Eizo Foris FG2421 monitor ?
Yep.
120Hz input.
It is a VA screen, not TN.
Official zero-motion-blur technology (and is on by default).
Can be disabled. Seems to work differently than a stroboscope backlight.
Nope, it's also a strobe backlight too. It says so in the
EIZO FG2421 manual, page 18.
To reduce motion blur
Reduces image blurs (motion blurs) which occur when displaying animated images.
Motion blur occurs when the eye recognizes liquid crystal transitions which come from changing screens
(frames). When “Turbo 240” is set to “On”, the backlight flickers in sync with liquid crystal transition*1 so the
change cannot be seen, thereby achieving clear images with less blur.
*1 This monitor converts 120 Hz input signals into 240 Hz within the panel, and doubles the refresh rate to draw two
images per frame. At the first display the screen is refreshed, and at the second display the screen is displayed
correctly. When “Turbo 240” is set to “On”, the backlight is turned off for the first display.
If it looks like a duck, quacks like a duck, it is a duck -- it's a strobe backlight, just like LightBoost (unofficial) and G-SYNC's upcoming low-persistence mode (official).
Is this the first screen that has been build especially for zero-motion-blur ?
- It beat G-SYNC to official announcement
- LightBoost is unofficial.
So yep, this is the first official modern vendor-sanctioned LightBoost-like mode intentionally to reduce motion blur. (I'm assuming Eizo is also sending AnandTech a review unit too. Eizo is also sending me a review unit as well). BENQ did come out with AMA-Z in year 2006 and others, which attempted to use backlight modulation to reduce motion blur, but those were horribly inefficient (Why? Explanation at TFT Central about
how today's strobe backlights are more efficient).
2014 is an exciting year of low-persistence strobe-mode monitors!
LightBoost modes. G-SYNC modes. Turbo 240 modes. And possibly other brand names of strobe backlights.
