NOT FOR GAMING.
People below saying there isn't ghosting; I have NO idea what monitor they're reviewing....

The good news is the Samsung has a strobe backlight similar to LightBoost. Follow the Samsung Zero Motion Blur HOWTO.

For better color, change “Magic Angle” to “Group View” in the Samsung's menus. However, if you already did this, try the different settings and attempt to re-calibrate. Also, you can adjust colors via AMD Catalyst or nVidia Control Panel; if your monitor's picture adjustments are not letting you.Mark I tried that and it left the screen with a strong blue hue.
