It is possible to do software-based black-frame insertion in 60 fps software (e.g. emulators) for 120 Hz LCD computer monitors. A source code modification completely eliminates MAME motion blur!

Also see the mameworld.info announcement.
Although this benefits most 120 Hz setups, this completely eliminates LCD motion blur when using emulators on compatible LightBoost 120 Hz LCD monitors! LightBoost, originally designed for 3D, is manufacturer-limited to work only at above 100 Hz (an unfortunate artificial manufacturer restriction). Fortunately, simply blacking out every other refresh (black frame insertion) provides the zero motion blur effect on LightBoost displays (LightBoost HOWTO) at 60 frames per second!
NOTES:
- Source code patch available in comments! It’s a very small patch.
- Executables now available for download! MAME for 120 Hz displays.
Unzip into a folder, put your legal ROMS in the ‘roms’ subfolder, and run the executable (32-bit and 64-bit versions included). For ASUS/BENQ 120 Hz monitors, enable LightBoost first. For Samsung 700D/750D/950D, follow the Samsung HOWTO first.
- See comments for more info.
- More information can be found in the mameworld.info forum thread.
IMPORTANT:
- You must have native 120 Hz, such as a LightBoost monitor.
- Will NOT benefit 60 Hz displays
- Will NOT benefit HDTV’s; most don’t accept 120 Hz from computer (some exceptions).
