Apply the optimum resolution when using FreeSync.

The refresh rate setting method please refer to Q & A → How can I change the frequency?

The FreeSync function is only enabled in HDMI or DisplayPort mode. Use the HDMI/DP cable provided by the manufacturer when using FreeSync.

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 FreeSync 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 Center.

If you change the screen resolution while the function is On, the screen may intermittently blank out due to the graphic card. Set FreeSync 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.
