That's a stunning testimonial; one of the better ones I've seen lately.
Mind if you tell me which colorimeter you used to dial in the colors?
I've been shopping for a colorimeter to join the Blur Busters equipment suite.

I just used the settings vega posted in his build thread on the hard forum and colors are very, very good. The red tint is all but eliminated with Vegas settings! Now that you have me hooked on 2D lightboost I am building a similar 3x1 portrait setup same as vega.....the other two displays are already in the mail and once I get a spare Titan or two I will invest in a colorimeter to do it up right.

My Overlord OC (catleap 2b) does 130hz and looks great with its IPS IQ, but as you know its still has crap motion blur despite its refresh rate. My Fw900 does perfect motion with perfect colors but CRTs produce a soft fuzzy image compared against LCD displays. The lightboost asus is a combination of the best of both worlds you get the sharp image of the LCD combined with 95% of the motion clarity of a CRT, which equals complete WIN! I am in awe at the clarity of motion (im rocking 10% LB) and my eyes do not fatigue anymore because the smooth motion is much more relaxing compared against the constant image smear that I got from the Catleap.

Anybody that downs these lightboost displays without trying them is ignorant. I should know, I was one of the haters, one of the scoffers, but now I am a believer! My FW900 is back in the closet and my Overlord OC is in the trash!

Yeah like a really bad song on the radio that the station keeps repeating and repeating.
In time you find yourself tapping your foot and singing along.
It's like being programed.

Otherwise, the repeated refreshes ends up contributing to sample-and-hold motion blur (double image effects, stutters, increased motion blur, etc). The stroboscopic backlight is enabled only at certain refresh rates (e.g. 100 Hz or 120 Hz), and you need fps=Hz for best motion on stroboscopic displays (CRT, LightBoost). LightBoost and other stroboscopic backlights doesn't look awful at just 60fps, just that most benefits disappear if your strobes aren't synchronized with framerate (which requires frame rate equalling refresh rate).

So you definitely do need 120fps @ 120Hz -- preferably 100fps
Which you can easily do on most systems with a just a high-500 or 600 series GTX if you just run older games (Source engine games). However, to get even just 100fps in games like Crysis 3, you need a Geforce Titan to pull that off. Games like Quake Live, Counterstrike and Team Fortress 2 have no problem attaining 120fps; those games are still fairly popular.

P.S. New Samsung tip. Better colors during stroboscopic mode; change Samsung OSD setting “Magic Angle” to “Group View”

If, let's say, I can only reach 110Hz for a particular game then would it be better to use LB with 100Hz refresh rate or should I stick to 120Hz? Simply put, when do I need to switch to 100Hz when using this hack?

Off topic: I suggest you use multi-quoting in replying to multiple posts, it's the correct way in these forums thumb.gif

Wow!

I don't see how it could be better. I just ran that test myself, on my CRT, and it's completely clear and smooth, with no motion blur. I have to believe an FW900 can do the same thing, and you can't get better than 100 percent efficiency.

Vega is saying that the LCD crispness combined with CRT like blur free smoothness puts the lightboost 2D display over an FW900. I have an FW900, Overlord OC (Catleap 2B) & an Asus VG248QE and this has been my observation.

PRO / CON

FW900 = CRT blur free smoothness + perfect color / CRT "fuzzy" picture
Overlord OC = LCD crispness + high resolution, refresh rate / Motion is still a blurry mess
Lightboost 2D = LCD crispness + 95% CRT like blur free smoothness / Colors & brightness get sacrificed

Now throw three of those ligthboost 2d panels next to each other in portrait mode and you have yourself a 3240x1920 high resolution, blur free mega gaming display party! Anybody that downs these lightboost displays without trying them is ignorant. I should know, I was one of the haters, one of the scoffers, but now I am a believer! My FW900 is back in the closet and my Overlord OC is in the trash!

Well, I'm glad it's working so great for you. Personally, what you call "LCD crispness" has always given me a headache if I look at it too long, which is why I still use a CRT for everyday use.

LCD technology improves all of the time, and I'm not surprised that they're finally figuring out ways to eliminate motion blur on that technology.

So is this really legit? I'm sick of being let down every time people claim that LCDs have finally matched CRTs.

I can't stand anything less than perfect 120hz or 150hz CRT refresh rates. It matters enough to me that I quite gaming altogether when companies stopped supporting the drivers for the FW900 and I couldn't get it working consistently.

As someone who as owned four FW900's and now 3x LB setup, it's legit. wink.gif

Look at the media coverage and decide for yourself.
Go check the amazon.com reviews for the VG248QE monitor, some of them even mention the LightBoost tweak as a buying consideration.

To temper your expectations though;
-- CRT quality is in specific to the lack of motion blur
-- LightBoost 2D is something not officially advertised for nVidia.
-- You still have the lower color quality of TN LCD and the LightBoost picture is mis-calibrated so you need to readjust your colors to get the color quality back.
-- It's a bit hacky to enable if you don't have the shutterglasses emitter, though there's now some new ToastyX Custom Resolution Utility instructions that make it easier. (NOTE: It happens ToastyX Custom Resolution Utility makes it easier to re-enable high-refresh rates on Sony FW900 to work properly on newer Windows systems; in case you still have your FW900).

LightBoost is not for everyone; especially if you're sensitive to having CRT-perfect color/blacks.
However, if you are extremely sensitive to motion blur and have always hated it even on regular 120 Hz LCD's, this is finally the LCD "holy grail" some people was waiting for. Especially if you tweak it downwards to a LightBoost setting of 50% or less.

There's a large number of rave reviews throughout several forum threads, including HardForum, overclock.net and many others.

Bought a VG248QE yesterday. I don't have any Nvidia cards, so Lightboost will have to wait. But hey, 144Hz is still an improvement from a crappy 60Hz panel, I would think. Plus, I'm hopeful that somebody will figure out how to execute Lightboost outside an Nvidia environment. We'll see.
