FreeSync technology is solution that eliminates screen tearing without all the usual lag and latency.
This feature will eliminate screen tearing and lag during game play. Improve your gaming experience.
● Game Mode - Off: Disable FreeSync.
● Game Mode - On: Turn on the AMD graphics cards' FreeSync function. You may experience intermittent flickers
when playing some games.

" This menu is not available when Multi View Mode is enabled.
" The FreeSync feature is only enabled in HDMI (with the exception of the port) or DP mode.
Use the HDMI cable provided by the manufacturer when using FreeSync.
" If the FreeSync function is in use and the text displayed on the PC screen looks blurry or corrupted, resolve the issue by
changing the resolution of the PC screen to the recommended resolution.
" If you set the HDMI Mode to 1.4, the FreeSync Premium pro function is disabled.
If you use the FreeSync function while playing a game, the following symptoms may occur:
● The screen may flicker depending on the type of graphics card, the game option settings, or the video being
played. Try the following actions: decrease the game setting values, change the current Game Mode to Off, or
visit the AMD website to check your graphics driver’s version and update it with the latest one.
● While you are using the FreeSync function, the screen may flicker due to variation of the output frequency
from the graphics card.
● The response rate during the game may fluctuate depending on the resolution. A higher resolution generally
decreases the response rate.
● The sound quality of the monitor may be degraded.
" If you encounter any issues when using the function, contact the Samsung Service Centre.
" If you change the screen resolution while the function is On, the screen may intermittently blank out due to the graphic
card. Set Game Mode to Off and change the resolution.
" The function is unavailable in the devices (e.g. AV devices) that have no AMD graphic card. If the function is applied, the
screen may have malfunction.
