Zero Motion Blur LCD's have arrived -- Game friendly, low input lag, CRT-sharp motion!

post #1 of 10

The new LightBoost strobe-backlight LCD computer monitors (select models of ASUS and BENQ) have zero motion blur LCD! No interpolation, low input lag, and videogame friendly.

BlurBusters Blog Guide:
HOWTO: Zero Motion Blur on LightBoost LCD Displays

TechNGaming Guide:
Eliminate Motion Blur While Gaming With NVIDIA LightBoost!

All LCD ghosting, trailing, coronas, virtually completely disappear! (95% gone)
Normally, LightBoost is used for 3D operation, but these instructions enable the LightBoost strobe backlight for 2D gaming, no 3D glasses necessary, no glasses emitter necessary. At this time of writing, zero motion blur LCD's are ASUS VG278H, BENQ XL2420T, BENQ XL2411T.

With a LightBoost strobe backlight, you're impulse-driving instead of sample-and-hold. The pixel persistence is kept in total darkness, and the backlight is strobed when pixel transitions are virtually completely finished (>99%+). The strobe length can be shorter than the pixel persistence, breaking the pixel persistence barrier. Motion blur now becomes below human perceptible levels, no blur, can even tell individual pixels even moving at 960 pixels per second. PixPerAn text speed score of 30. You can disable the strobe backlight, whenever you don't need the zero motion blur.

High-speed 480fps / 1000fps video of LightBoost strobe backlight bypassing pixel persistence as the motion blur barrier:


NOTE: This does not mean CRT color. Just zero motion blur like CRT. (Multiple gamer reports: "It's like a CRT!" several third party confirmations). These LightBoost LCD's are confirmed to have far less motion blur than plasma displays. However, they do not have as good color quality, and blacks are not as good. That said, if you need the clearest and sharpest possible motion without getting a CRT, and without interpolation, and game-friendly low input lag, these have become the elite gaming monitors. For fast-twitch FPS video games such as Quake Live or TF2, these are presently world's lowest motion blur LCD displays. The BENQ XL2411T actually measured 1.0ms MPRT (Motion Picture Response Time), when LightBoost was enabled, which confirmed the manufacturer was being honest with their 1ms rating. Hopefully game-friendly zero motion blur LCD technology arrives in HDTV's, at least as an option setting.

But this only for AV, no sound from HDMI when you input Xbox or PS3 in monitor

And sorry for doublepost, but its dark TN

Just so you know, LightBoost is only for PC gaming. It is a component of nVidia 3D Vision 2 compatible computer monitors.

So this won't benefit from Xbox or PS3 because this is a computer monitor.

FYI, immetjes on overclockers.co.uk forum, has posted a pretty impressive
PixPerAn image BENQ XL2411T. I concur I'm getting the same thing.
Truly zero ghosting, zero motion blur, zero trailing, zero coronas.
The ultrafaint artifact is not noticeable without a magnifying glass.

Although pursuit camera images are better (e.g. MotionMaster Motion Blur Measurement Kit),
this is additional proof of LightBoost successfully bypassing pixel persistence (in addition to my existing 1000fps YouTube).

Lightboost in 2D is certainly working. I have a XL2411T since 17-Dec-2012 and I did the readibility test part and the little car of PixPerAn. (I also posted this on pcmonitors, but it is so good I'll repeat it here).

I have made sure the monitor was in 3D mode without actually showing 3D. Lightboost is on. Refresh rate is on 120Hz. I have made a Macro photo of PixPerAn, shutter speed 1/160s, ISO800. This is the result: http://www.avsforum.com/content/type/61/id/129630/

Compared to lightboost off you can clearly see that there is hardly any blurring. Here is a PixPerAn photo using the same camera settings: http://i.imgur.com/clcVc.jpg .I tried to get a picture at 120Hz with no lightboost. But whatever I did the monitor refused to get out of the lightboost mode when using 120Hz. Therefor this picture is made at 144Hz.

I also did the readability test and was able to read rather easy upto level 24. At 25 it was going so fast I was only able to read the first 5 characters. I then tried the maximum of 30 and the text was still readable, however, because of the speed my head/eyes were unable to follow the text, it was still readable though.

Without lightboost I was able in the 144Hz mode to get with some effort upto level 10 of the readability test. After that the text became to blurred. I did the same test on my HP w2270h monitor and after level 8 or so the text became completely blurred.

in BF3 my scores definitly are improving. Especially in close combat circling around enemies. I'm able to keep on focus, where it used to blur all. GREAT! Also spotting foes from the corner of your eye when running, flying or driving improved a lot.
(I concur with this post, too!)

I'm curious, is the ghosting (or lack of ghosting) uniform vertically? Or does the top of the screen have more/less ghosting than the bottom?

It's very uniform vertically on my BENQ XL2411T.

For the ASUS VG278H, I thought it was uniform vertically, but I did more motion tests, and noticed an extremely faintly slight difference between top and bottom (e.g. 99% pixel persistence complete versus 99.5% pixel persistence complete) seems to occur for the top edge versus bottom edge. I had to do a lot of testing to notice this. Very, very, very subtle difference between top and bottom edge. I also have the 3D Glasses too, so I also verified if this also occured with crosstalk. Yep; same thing: The same pattern apparently also occurs with 3D shutter glasses (since the LCD is refreshed top-to-down, while shutter glasses are refreshed all at once), e.g. 3D crosstalk bleeding is slightly stronger at bottom versus top edge. Not by much, but a tiny bit. It seems to look like a tiny 1% difference; once I cancel-out interference from TN color shift by leaning up and down.

The new 1ms panels (ASUS VG248QE and BENQ XL2411T) appear to have far less crosstalk between refreshes. It seems roughly 10 to 50 times fainter crosstalk than the first-generation 3D-compatible LCD's (from 2010 and 2011; two years ago), and thus have a virtual lack of ghosting/trailing/blur/artifacting that I cannot see with my eyes, so there's absolutely no noticeable difference (to my eyes, at least) for the top edge versus bottom edge. If you prefer the full resolution of active 3D glasses (rather than half resolution of passive 3D), these panels are a big improvement. Although I mainly game without the 3D glasses, but keeping the LightBoost elimination of motion blur.

Mark,

Are their any consumer LED displays (50" or larger) that incorporate the Lightboost technology (not a monitor but a TV)?

Sony's interpolation-free "Motionflow Impulse" setting. It's a pure strobe-backlight Motionflow, just like LightBoost.
It's typically found in models such as HX950 series, and any new 2012/2013 Sony HDTV's containing the Motionflow XR 960 feature (these "960" Sony TV's typically include "Motionflow Impulse" too) That said, that modes strobes at 60Hz and not everyone likes the 60Hz flicker.

Some people, such as Chronoptometrist, like Motionflow Impulse, and it also works well with console games with a small bit of input lag (you have to disable Game Mode to access "Motionflow Impulse"), less than the input lag of interpolation.

LightBoost strobes at 120Hz and that is better, but video signals aren't natively 120Hz. Only way to easily get 120Hz source material is via computer. There are also also some TV's that support a true 120Hz (HOWTO: True 120Hz Capable HDTV's), as an alternate method of reducing motion blur from a HTPC connected to a TV (e.g. PC based video games on a TV).
