The LightBoost strobe backlight is good for both 2D (eliminate motion blur) and 3D (eliminate crosstalk). 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). Most of the overdrive overshoots and ripples is kept in total darkness. The strobes can be shorter than pixel transitions, breaking the pixel transition speed barrier! In addition, it eliminates the sample-and-hold effect. This produces a CRT effect on a LCD with zero motion blur.

There's a small amount of overdrive left, but 99% of overdrive is gone in LightBoost mode, on the ASUS VG248QE. You can also reduce the purple tinging in Samsung S23A700D version of the 3D mode by changing the "Response Time" to "Normal" before switching to 3D mode. But it is not perfect. The newer panels such as VG248QE finish pixel transitions more completely. Although the S23A700D has much better colors than the VG248QE, there is near-zero overdrive on VG248QE when LightBoost is enabled. So the panels have finally been able to finish >99% of pixel transitions.

The checkerboard pixel pattern on the VG278H is compensated by VG278H having less motion blur (due to LightBoost) than the old 2233rz. During fast video games, there is about 6 times less motion blur on the VG278H than the 2233rz (if LightBoost is enabled), which can greatly compensate, if you like high-framerate 120Hz gaming.

See High Speed Video of LightBoost.

Questions: LightBoost FAQ

You can turn on LightBoost using the new ToastyX Strobelight Utility. (Easy ON/OFF via a hotkey).

Supported Monitors: ASUS VG248QE, BENQ XL2411T, ASUS VG278H, ASUS VG278HE, BENQ XL2420T, BENQ XL2420TX, BENQ XL2720T, AOC g2460Pqu, Acer HN274HBbmiiid
The tech isn't perfect, far from it. The ASUS has input lag with ligthboost, which is utter crap when using a 120hz panel - you want FAST RESPONSE. The Sammy has a purple tinge. The ASUS also has half-resolution 120hz, meaning that checkerboard pattern.

That leaves the BenQ in the 3D Vision compatible space, and the 23" Samsung S23A700D in the more general-purpose 3D/120hz space. Note, that I am using my S23A700D with 3D Vision, through some special tweaking. It's not perfect because I need to adjust the monitor every time I turn on 3D, but it looks simply great.

I got a XL2420T because of the 120hz capability, low input lag when "Instant Mode" is turned on, and lightboost capability in 2d.

First of all.. Lightboost.. It works, it looks great. Problem I found is that there is much too much input lag when it is enabled.. the issue is because "Instant Mode" is disabled with Lightboost, and you are not able to turn it on. So it looked good, but was completely unplayable for me.

So, what about with Lightboost off. Just running like it was meant to be with Instant Mode and 120hz. Huge Improvement. This is how I run it.

However, is it as good as CRT? No. It still feels maybe a tiny bit delayed/input lag. Or maybe it is because of the ghosting. Either way, XL2420T definitely loses out to CRT.

Conclusion, Lightboost isn't good at all if you are a FPS player.
Nice post. This is exactly what I wanted to know about 120hz.

Samsung make great monitors. They have great picture quality, long life and they look great. They're not overly expensive either(Roughly €150 for us in the EU for a 22" 1920x1080 monitor ~2ms).

I'm a happy Samsung SyncMaster owner. If this one ever breaks(Hoping it doesn't) i'm replacing it with another SyncMaster. The only downside is they're terrible for multi-monitor set ups(Specifically for playing games).

The OP is comparing 24", 120hz refresh rate monitors. Not 60hz. But you are right, the Samsung S23A700D is only $329 at good stores, and is a fantastic 23", 120hz monitor. For that price, you can't go wrong.

after posting in this thread, i was inspired to try lightboost again.

redid all the drivers for the video card, did all the lightboost stuff etc.

i'm torn now.

it's really not that bad as far as input lag. i think what i perceived as a huge jump in input lag may have been a problem i was having with lower FPS for some reason.


anyway 120hz monitors are pretty nice, lightboost.. see if you like it or not. but like i said before.. CRT is still much much better.

most 120hz monitors support lightboost anyway.. with or without it 120hz is the way to go unless you're staying with CRT.

Yeah I'm using CRT but I'll switch eventually.

I wasn't trying to tell him to get a 60Hz monitor just informing him that Samsung have some quality monitors and they're a decent price. Well worth the investment and he won't be disappointed by them.

well if my GDM-FW900(with a couple of matching CPD-520P, one on each side of it) setup ever dies...I'm gonna have to check out these new fangled "LightBoosty" capable monitors

good reading

..thanks for the info and posts mdrejhon, Grunt7684, sixece, (and notRude for opening one of my favorite can o worms)

gotta say i'm not happy with my xl2420t at all. i'm just not used to the input lag, lightboost or not. thinking about setting up my crt again but i love the benq just for its 24", its nice to do work on.

Did you make sure you have it set up in windows to respond at a 120hz refresh rate? Did you use a Dual-link DVI cable?

yes.
120hz
dual link dvi

lcd monitors have input lag. no other way around it.

this monitor is one of the best lcd for low input lag. but it's still there.

really does feel like a compromise playing on it. i get to save on electricity, have a larger screen, save space on my desk. but for pure performance.. i miss my crt.

I've had a Benq XL2410T for about 3 years now, which is an older model. It was one of the first 120hz LED monitors.

Under 60hz there is some input lag (common for 120hz screens), but nothing noticable under 120hz. Check games are not switching down to 60hz.

did all the tweaking comparisons in game.

lightboost is 100000% staying off for CS.

and imo xl2420t is a lot better for CS at native resolution.. 1080p
