Guys, if you mainly use a computer monitor to play video games a lot (and your eyes were used to a CRT before, and didn't mind it), there's now a way to shatter the LCD pixel persistence barrier! CRT quality motion in an LCD!
There's a recent discovered tweak/adjustment for a feature originally designed for 3D (LightBoost), that has an amazing side effect of completely eliminating perceptible motion blur for 2D!
This high-speed video proof (1000 fps) demonstrate a specially configured LightBoost strobe backlight successfully bypassing pixel persistence as the motion blur limiting factor:
The backlight is turned off while waiting for pixel transitions (unseen by human eyes), and the backlight is strobed only on fully-refreshed LCD frames (seen by human eyes). The strobes can be shorter than pixel transitions, breaking the pixel persistence barrier!
Although these backlights are normally used to brighten 3D images, they have a side effect of eliminating motion blur. As a result, many video gamers have started forcing LightBoost in 2D mode (even without the 3D glasses) to get the zero motion blur benefit. These superior modern strobe backlights such as LightBoost have recently been discovered by many users to successfully eliminate motion blur on LCD displays without flicker (unlike old BENQ AMA-Z 2006, primitive scanning backlights, etc). Most eyes can't see 120Hz flicker, and (at least within games, not desktop) it is potentially more pleasing than PWM because of lack of motion blur (there are people who gets headaches with PWM but not with CRT). (As a rule of thumb, if CRT flicker at 120 Hz does not bother you, then LightBoost will be fine for gaming, or you can just turn off LightBoost). Normally LightBoost was for 3D, but it's also useful for 2D too. Several 120 Hz monitors now have a strobe backlight feature that can be enabled, to allow CRT-quality motion on LCD. Eliminating even more motion blur on 120 Hz LCD monitors, give a better competitive advantage in online FPS gaming!
PixPerAn Tests on BENQ XL2411T and ASUS VG278H
baseline - 60 Hz mode (16.7ms frame samples)
50% less motion blur (2x clearer) - 120 Hz mode (8.33ms frame samples)
60% less motion blur (2.4x clearer) - 144 Hz mode (6.94ms frame samples)
85% less motion blur (7x clearer) - 120 Hz mode with LightBoost set at 100% (2.4ms frame strobe flashes)
92% less motion blur (12x clearer) - 120 Hz mode with LightBoost set at 10% (1.4ms frame strobe flashes)
When enabling LightBoost (HOWTO) and then adjusting the LightBoost setting, I was amazed when I saw the 2ms ASUS VG278H monitor (hacked to force LightBoost for 2D) have an actual true PixPerAn measurement of 1.4ms in this special mode. Oscilloscope photodiode tests amazingly confirmed this. High-speed video confirmed this.
Today, we are truly in a new era where pixel persistence is no longer the motion blur barrier! There are now LCD's that truly behave as impulse-driven displays similar to a CRT, for those people who absolutely need the clearest possible fast motion available today, above all else. It's a great time to be a gamer!
NOTE: You can also turn on/off the CRT-style LightBoost strobe backlight mode, whenever you don't want it. Manufacturers should make it better advertised for motion blur, and easier to turn on/off!
