First, there are now multiple brand names of motion-blur-eliminating strobe backlight modes
. Samsung's brand name for their equivalent of LightBoost is different.
Right now, there's multiple brand names, including:
- LightBoost -- monitors with NVIDIA 3D Vision
- Ultra Low Motion Blur (ULMB) -- monitors with NVIDIA GSYNC
- Extreme Low Motion Blur (ELMB) -- brand name by ASUS
- Dynamic Acceleration (DyAc) -- brand name by Zowie/BenQ
- Samsung advanced motion blur reduction
- LG MOTION240, Eizo TURBO240, etc.
LightBoost was the original "good" strobe backlight mode, but has now been superseded by superior modes in newer high-Hz gaming monitors
Now, the good news:
Yes, your Samsung C27FG70 monitor has an equivalent of the LightBoost strobe-backlight technology, but is not called "LightBoost". The Samsung motion blur reduction technology is more generically named, but can easily be accessed via on-screen-menu display.
Instructions for most newer "Motion Blur Reduction" (MBR) monitors
1. First, temporarily turn off your VRR (FreeSync or GSYNC) and then select 120Hz.
2. Next, go to a motion test http://www.testufo.com/photo
3. While watching the motion test, go through your monitor's menu and turn ON "Blur Reduction" (or something similarly named).
4. Your LCD motion blur will disappear (CRT clarity motion). Your picture may be dimmer; that is normal for most strobe backlight modes. You may also get a slight amount of strobe crosstalk
on some models (faint sharp double-image effect); this is normal due to LCD pixel response limitations. For most good implementations of MBR, the strobe crosstalk is faint enough to not be really noticeable in most normal gaming.
The Samsung C27FG70 monitor is a VA panel. VA panels are temperature sensitive. You will get better blur reduction if you warm up your monitor first, if you're in a very cold room
