Is it normal to lose all options in the nvidia control panel after setting up the light boost with strobe-light? I just today installed SLI with my 570's if that contributes to this.
I had that happen once. try changing your refresh rate through the windows settings. It brought the settings back for me.

Did not help. It seems the refresh rate wont change using windows options, it seems to apply but opening the window again shows 120hz.

This tool seems to be causing me a lot of problems, it randomly reinitializes in games to, turning off the light boost then re enabling it resulting in about 5-10sec of black screen while it sorts it self out. On top of that removing the options in the nvidia control panel.

I just reinstalled my drivers now checking the clean install option, and cant re enable sli. So for now i have disabled strobing, reinstalled drivers again and got my sli back on.

Will try getting light boost enabled using another method, this one doesn't seem to agree with me.

I was reading the LightBoost How To and it says the motion blur difference between 120hz and 100hz at 10% is only .3 ms.

So my question is, how much would you notice the difference between 120hz and 100hz? Mainly because 100hz/fps is easier to achieve.

The 0.3ms is almost not noticeable at all.
It's akin to adding one-third pixel of motion blur for every 1000 pixels/sec motion. Pretty negligible.

The 1ms difference between LB=10% and LB=100% is more noticeable, though. The full 1ms adds one pixel of motion blur for 1000 pixels/sec motion (Ideal conditions: 120fps@120Hz perfectly framerate=Hz matched, zero microstutters, like playing older games such as Team Fortress 2 or Counterstrike).. So adding +1ms of motion blur adds 2 pixels of motion blur for 2000 pixels/second motion -- one full screen width per second -- this is just about noticeable during high-speed strafing motion with high-detail wall textures -- but not everyone sees it. It's impressive that the human vision *can* see a 1ms motion blur difference, at least under the more ideal motion conditions. Easier to see in motion tests such as PixPerAn, during perfectly fluid motion.

The bigger issue is input lag. There's less input lag at 120Hz than at 100Hz.
That said, 100Hz can be better looking for solo gameplay during times when your GPU cannot keep up at 120fps@120Hz (especially if you prefer to play with VSYNC ON or Adaptive VSYNC -- if you prefer microstutter-free motion). For competitive gameplay, stick to 120Hz VSYNC OFF -- that's lower input lag.

The difference between 100% lightboost and 10% light boost is still pretty subtle. I can't tell a difference at all, even when I know what I'm looking for.

Indeed, I'm not sure I would notice it outside PixPerAn, but I haven't actively tested it like that in a while. Pretty happy with my setup.

You can tell a difference when looking at the edges of textures--especially with text or sharp edges. It's easiest to notice with text, though, when scrolling or panning..

It's also quite easy to notice when looking at people's name tags while scrolling in something like Starcraft 2 or MOBA, when using vsync. It's a LOT easier to notice the difference at 100hz between 10% to 100%, than at 120hz, as mentioned above.

One other problem is that in any game where I would want to sacrifice color for smoothness, I would not be using Vsync, so the stutter that causes makes the image less smooth.

It is also game dependent.

I found it quite easy to notice LB=10% versus LB=100% with Borderlands 2 during VSYNC ON, in areas I'm able to play framerate=Hz (120fps@120Hz or 100fps@100Hz, solo gameplay, view distance slightly reduced to keep framerate high, use FXAA to keep framerate high). The thin black lines in Borderlands / Borderlands 2 are MUCH clearer during fast strafing / fast turns during LB=10% than LB=100%. One-pixel-thick black lines easily get motion-blurred to 2-pixels-thick or 3-pixels thick, while LB=10% prevents that from happening.

1 pixel of motion blur makes almost no difference with blurry textures, but 1 pixel of motion blur becomes noticeable with high-contrast edges. I even actually just barely notice 0.3 pixels of motion blur, as I do actually notice a difference between LB=10% and LB=40% when playing Borderlands 2, VSYNC ON, during framerate=Hz. The image quality/smoothness improves in Borderlands 2 during VSYNC ON to the point that the motion is so smooth (especially keyboard strafe left/right), that I start to notice the difference in small adjustments of the LB setting. I actually begin to notice 0.3 pixels of motion blur in that specific game. Very, very, very barely. But I get a slight amount of input lag that affects competitive gameplay, but I don't feel it for solo gameplay except when framerate falls. (Can also use Adaptive VSYNC too).

In most dungeon games that are murky, dull, low-contrast, blurry textures, I cannot tell apart LB=10% and LB=100%. But Borderlands 2 is one of those games that makes LB=10% versus LB=100% very noticeably clearer looking (at least during framerate=Hz operation, such as when VSYNC is on, and use FXAA) due to all the thin black lines.

Hi, I cannot get to work lightboost with my VG248QE.
I’m running it on a laptop which has VGA and HDMI only, no DVI. So I plugged it in to HDMI. Tried every method above (I don’t have glasses) , but I cannot get to have refresh rates higher than 60. And I cannot get Lightbosst active (it is greyed out by default) in monitor’s OSD menu.

While trying methods there were 2 things i noticed;
-Nvidia drivers start to show DVI connection instead of HDMI after the hack.
-While trying different methods above a few times, I was once able to enable stereoscopic 3d turn on and off. But it requires setting up again now after I restore the settings to defaults.
