CaptainTom :
I gotta wonder if 1 ms vs 5 ms really makes a difference...
Normally,
they don't. Both of them are a small fraction of the length of a visible refresh. So motion blur from the sample-and-hold effect is more dominant than the pixel transition speed.
Scientific papers explain this (Sony scientists, Panasonic, Nokia, etc)
However, if you shorten the pixel visibility time ("hold" time, as in sample-and-hold) either by higher Hz, interpolation, adding flicker, CRT, black frames, strobe backlight, etc.), things change. There are more demands again back on the pixel transition's speed, and the difference between 1ms and 5ms can become a big chasm. (3D crosstalk during active shutter glasses -- is another excellent use case of why 1ms vs 5ms sometimes matters -- you need to clean up the refreshes very fast between frames)
sephirotic :
No TN screen can match in response time and input lag of such monitor.
Agree that input lag is an issue (LightBoost can add half a frame). But for some people, motion clarity is more important (
screenshots of better battlefield3 scores with LightBoost). That said, LightBoost TN's can have less motion blur than some CRT's such as the Sony FW900. The strobe backlight flashes for a shorter time period than the phosphor decay of a Sony FW900! There are many rave reviews by dozens of people who see the motion blur benefits. From the Internet, there are several hundreds of posts, similar to:

Then yesterday I, for some reason, disabled the 3d and noticed there was no ghosting to be spotted at all in titan quest.
It's like playing on my old CRT.

I can
confirm this works on BENQ XL2420TX
EDIT: And OMG i can play scout so much better now in TF2, this is borderline cheating.

Thanks for this, it really works! Just tried it on my VG278H.
Its like a CRT now!

Oh my, I just got Skyrim AFK camera spinning (which I used to test LCD's versus the [Sony CRT] FW900) to run without stutters and VSYNC locked to 120.
This Benq with Lightboost is just as crystal clear if not clearer than the FW900 motion. I am in awe. More testing tomorrow. Any of my doubts about this Lightboost technology have been vaporized! I've been playing around with this fluid motion on this monitor for like 6-hours straight, that is how impressive it is.

way to go vega enjoyed your review and pics ..thanks for taking the time .got my VG248QE last friday .
replacing my fw900 witch is finally taking a rest in my closet .
OCN post (Romir)
Thanks for the timely review Vega.
I went ahead and opened mine and
WOW, it really does feel like my FW900. I haven't tried a game yet but it's down right eerie seeing 2d text move without going blurry.

With my Asus VG278HE at 120Hz and Lightboost (the Lightboost registry hack doesn't currently support 144Hz) playing at 1080p I am pretty much brutalizing my competition. Even with its 2-5ms input lag, which is worse than the 1ms of my old 120Hz monitor the difference with Lightboost is so huge the input lag literally becomes a non-issue. The only thing that matters now that I don't experience any motion blur is my true reaction time.
Even if the reviewer of the monitor doesn't believe he sees motion blur, other readers may too as well. But I think Christian will begin to notice it, if looking carefully. (Important: Motion blur is different from ghosting). Also,
I am willing to bet $500 cash (I'm the owner of the Blur Busters blog) that Christian Eberle can't read all of the map labels at 960 pixels/second at 120fps @ 120Hz or 144fps @ 144Hz in the TestUFO Panning Map Test, at www.testufo.com/photo#photo=toronto-map.png ... enabling LightBoost makes the fast-panning map as perfectly clear as a stationary map even while fast-panning.
This is relevant to gaming, as fast panning relates to being able to identify enemies and shoot them while turning, without stopping turning first, giving people a further advantage in gaming. (Make sure you are running at full framerate=Hz, and have a microstutter-free 1000Hz mouse). Things from CRT gaming days, like circle strafing, becomes easier. And controlling a helicoptor during high speed low-flybys, becomes easier as you're no longer bottlenecked by 120Hz or 144Hz LCD motion blur, and can aim at camoflaged enemies easily while they pass by at high speeds. Obviously, many LCD gamers don't use the old blur-dependant CRT gaming styles.
AnandTech
even agreed that LightBoost has benefit. TFTCentral has an
article about LightBoost. Unlike yesterday's LightBoost hacks, a utility called ToastyX Strobelight now makes it easy to press a hotkey to turn ON/OFF LightBoost (You can do it even while viewing a motion test too).
Also,
Sony and
Eizo has recently followed suit with strobe backlight technologies too. This time officially (as a blur elimination feature), rather than a bundled feature as part of 3D Vision.
Everyone who did this, was able to see a difference in TestUFO when using a strobe backlight. Ability to see in games is frequent, but can definitely vary due to the wide range of different games/playstyles/framerates/microstutters. But the point is, many people are actually more sensitive to motion blur than expected. Just because a person can't see motion-blur (or need glasses, or is deafened), does not mean other people aren't more sensitive to motion blur (or better vision, or better hearing)! So I suggest future reviewers test out LightBoost anyway, as strobe backlights are slowly becoming official features of certain displays (e.g. Sony KDL55W905A "Game Mode Motionflow Impulse" feature, Eizo FDF2405W "Blur Reduction" feature).
If you have the VG248QE, at least try the
LightBoost HOWTO and then view the
TestUFO motion tests before/after.
