Lightboost has 1 extra deferred frame of input lag from strobing (this reduces the amount of crosstalk at the bottom of the screen).
The Benq equivalent is setting Strobe Phase to 000.
Lightboost uses accelerated scanout to increase the blanking interval to give the pixels more time to finish color transitions during a frame. This causes a reduction in "Strobe Crosstalk".
Benq actually reverse-enginnered Lightboost so thanks to some people here (masterotaku), we found that Lightboost uses a certain internal blanking interval (Done on the LC panel), that is identical to if you created a custom resolution and used a custom vertical total value of "1500" and enabled Benq Blur reduction. I tested it and at 120hz refresh rate, the crosstalk amount is identical when using a VT 1500 tweak.
What you need to do then is to download ToastyX Custom Resolution Utility and download the ToastyX pixel clock patcher (For AMD/Nvidia), run the pixel clock patcher and reboot (or restart the driver with restart64.exe).
Then if you want the exact same crosstalk settings Lightboost gives, you would create the following custom resolutions:
(in ToastyX CRU, not in the Nvidia control panel or the AMD panel!)
"LCD Standard": then change to "Manual":
100hz: 1920x1080, front porch (48,3), sync width (32,5), Horizontal total (2080), Vertical Total (1500).
Set strobe phase to 000 before enabling blur reduction. Setting strobe phase higher than 049 (120hz) or 059 (100hz) with a VT tweak applied will turn off the backlight.
Then enable benq blur reduction. Strobe Duty set to 009 equals Lightboost 10%, and strobe PHASE 000.
