Game bug. Mode switches in LightBoost is really slow, so that causes the 2-3 second blackout (same as when turning on/off lightboost).

Yep. Universal prevention:
Re-run strobelight-setup.exe and only install "120Hz strobed".

You won't be able to turn off LightBoost, but it will prevent the blackout caused by video mode switches.

it isnt hardware issue dont be worried, just use ToastyX latest beta to turn LB after reseting the display and it should open only on the startup and not in regular use

BF3 has a known mode-switch bug, even without ToastyX.

Naw I don't play BF3. Happens on desktop too.
That solution sounds PERFECT for what I need! I'm always in lightboost mode, no point in installing 121hz non-LB anyway. Why didn't I think of that??

Yep, It fixes the LightBoost 3-second blackout at the desktop, including during logging on/logging off.

Surround and lightboost is still broken with 331.65. Just wanted to put that out there in case anyone was wondering.

Hey guys. I recently purchased a BenQ XL2420TE after lusting for a 120hz/144hz/Lightboost monitor for a good while, and after reading around a bit recently I'm trying to decide if I should return it for two different reasons.

The first is the arrival of G-SYNC, which seems to be a dramatically improved version of Lightboost, at least for my purposes. I don't have a super-powerful computer setup, so while I'll be above 60 in all games, I may not be consistently above 120; making G-SYNC likely a better option for me. Color quality is pretty important to me as well.

Which leads me also into my next reason, which would be returning the XL2420TE for the XL2720T which, thanks to vega, apparently has better color quality using Lightboost. I'm assuming it's still a consensus that if I spent the money on the XL2420TE and intend to use Lightboost, an XL2720T would be a better deal?

I guess my questions are:
1. Is the difference likely to be dramatic enough to wait at least half a year for a G-SYNC monitor (it'll be about half a year, right?). I'm really excited to have a Lightboost-esque monitor now, but I'll wait if it's a more logical decision.
2. If I decide to go with a Lightboost monitor now, my main concern with the XL2720T is the low-ish pixel density of a 27 inch 1080p monitor. Vega, you seem to take your PC gaming pretty seriously; do you notice that reduced pixel density at all? Or is it something that I'd just immediately get used to?

Thanks!

Problem seems to be solved, No issues in the past two days. Will keep monitoring.

No posts about Eizo Foris FG2421?
http://gaming.eizo.com/products/foris_fg2421/
http://www.flatpanelshd.com/review.php?subaction=showfull&id=1383107475

Built in variant of Lightboost, VA-panel, very responsive. Probably going to get one as this is basically what I've been looking - 120hz and good colors.

Eizo has announced a strobe backlight monitor!!!
http://www.eizo.com/global/products/foris/fg2421/index.html

Eizo Foris FG2421


It's a 240Hz VA monitor. It's really a 120Hz native monitor but uses a double-pass refresh and strobe backlight to flash towards the end of the second refresh.
Great 5000:1, great colors, low input lag, AND strobe mode! No crappy LightBoost color.
Works on any graphics cards; and at enthusiast gamer prices!

The manual confirms it is a strobe backlight technology.
It says so in the EIZO FG2421 manual, page 18.
Quote:
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).

- It beat G-SYNC to official announcement
- LightBoost is unofficial.

So 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.

When FG2421 arrives, I'll be benchmarking it against LightBoost.
