nVidia 3D LightBoost can be used in 2D mode for zero motion blur

Zero motion blur on LCD computer monitor is possible in an out-of-the-box LCD monitor, without needing to hack a backlight. Tech Gaming has posted instructions for enabling nVidia 3D LightBoost during 2D mode:

Yes, I’ve finally found the holy grail of gaming in 2D mode on an LCD monitorzero motion blur! It literally displays motion as good as a CRT and then some. I was so stoked when I first saw the effect today, that my jaw literally dropped and I played my game open mouthed, it was that awesome! This combined the crystal clarity of an LCD display with the motion sharpness and smoothness of a CRT, all at a fast 120Hz screen refresh rate. This is something I’d never seen before and looks truly amazing – better than even a CRT.

This is great news. This works on the Asus VG278H computer monitor! If you’re dreaming of zero motion blur on a LCD monitor, the wait is over! No hardware hacking needed.

Update: I’ve purchased the VG278H monitor & confirm this: This LCD computer monitor has zero motion blur when adjusted this way! HardForum thread.

Lightboost looks incredible in my new 4211T . I bought it after reading about lightboost because I am an old school, emulators enthusiast and I could now wait until I play MAME and Snes emulators like CRT. I have lightboost working properly, but emulators still have blur and ghosting all around. Why? Because they are 60fps and to get to 120Hz they seem to simply duplicate frames/wait (via triplebuffering or vsync), and that seems to blur the image so lightboost is not helping here. If I force the emulators to x2 speed, all go cristal clear. Any solution I can try to get cristal clear CRT like output with proper speed?


Alas, this is correct; 60fps@120Hz will always have the double-frame effect. There’s no easy workaround because LightBoost does not function at 60 Hz (or that would have been the solution).

There’s a solution but the MAME programmers need to make a minor modification to MAME: Black frame insertion mode. Perhaps write a message to MAME to add a black-frame insertion feature for 120 Hz computer monitors. Basically, insert a black frame every other refresh. This will solve the problem, and produce the 60 fps @ 60 Hz “CRT effect” (especially when combined with LightBoost)

Alternatively, the nVidia graphics driver MIGHT be tricked to flickering at 60 Hz with a black frame insertion effect:
But I don’t like this method; it makes everything (including Windows desktop) flicker terribly; it should be limited to certain apps such as MAME or emulators.


I only have 120Hz on my VG278H, so I am unable to test 144Hz. However, if you get 144Hz LightBoost working in 2D mode, please post here!

Don’t forget to adjust your monitor to a brightness of 92 when you enable LightBoost2, since on Asus monitors, LightBoost2 looks dim in 2D mode (The image brightening is for 3D, with the strobes normally timed to when the shutter glasses are open). I have been hearing Benq’s are much brighter, but I’m now waiting for Vega’s review on HardForum now.


I know that, all of it. I solved it (just unchecked Enable 3D ..)

It was really locked and I had fps_max 256, no vsync on.

Now I have good FPS and LightBoost Mode, everything works fine 😉

Just one question scanmaster:

Tomorrow or in 2 days I will get ASUS VG278HE, I dont have this 3d Kit again (so I need to bypass it with an .inf installation of another monitor. Is it possible to get LightBoost Mode with 144 Hz?)
