Reporting back! If you disable Stereoscopic 3D in windows, make sure your AMD Display settings are at 120Hz, and your monitor is in Frame Sequential mode, you do get the benefit. I CAN SEE SOUNDS.

I wish it wasn't so dark!

OK -- let's agree on this -- I think two threads can be merged:

MERGE:
"Better LightBoost Color -- Upgrade to nVidia Geforce driver 320.18"
"XL2720T / XL2420T / VG278HE / VG248QE -- Easy LightBoost ON / OFF via hotkey"
INTO:
"Zero motion blur LCD!!! (nVidia LightBoost hack, looks like CRT, looks like 480Hz)"

However, the monitor-specific threads need to remain separate (VG248QE thread, XL2720T thread) as those aren't my threads, and they also cover everything specific to those monitors (and users talk LightBoost in those anyway). They definitely don't need to be merged.

Moderator, can you please merge the two threads, above?

So ToastyX basically isolated nVidias code for enabling strobe backlight. Shouldn't he be able to enable 144 Hz LB/Strobe then?

It doesn't work well with 144 Hz from what I remember, or at all.

The .exe works perfectly while in surround, takes at most 30 seconds or so to enable the 3 monitors. It's light years faster compared to the previous way thumb.gif Great job to all those who worked and helped made this thing possible for us all.

I thought it just wasn't supported at all.

Somebody accidentally got 144Hz working in LightBoost, but it was frameskipping in Refresh Rate Multitool.

144Hz requires Reduced Timings, and LightBoost requires an expanded vertical blanking interval. At 144Hz, there is not enough time between refreshes to strobe the backlight.

For those people in this forum, not familiar with the LightBoost strobe backlight timing and why you need to bump down 144Hz->120Hz to create enough room for the strobes between refreshes, see the high speed 1000fps video of LightBoost.

Well, is there a known maximum to lightboost? I'd be surprised if that turned out to be 120hz.

Is there any easy way to get light boost working at above 120hz, so I can test for myself?

It's definitely vendor-locked to 100Hz, 110Hz and 120Hz.
Doesn't work at 60Hz or 144Hz. We spent weeks trying to get LightBoost trying to work at other refresh rates. The monitor firmware is unable to trigger LCD-refresh synchronized strobes at a different frequency than within the range of 100Hz through 120Hz.

You can use ToastyX Strobelight to install a 120Hz LightBoost mode, and a 144Hz non-LightBoost mode.
(Add "120Hz strobed" and "144Hz" in strobelight-setup.exe)
Hit Control-Alt-Plus to switch to 120Hz LightBoost
Hit Control-Alt-Minus to switch to 144Hz non-LightBoost

So this can work fine with s27a950d? If so, definitely going to try it out when I get back from work in few days!
