Chapter 05 Configuring the PIP/PBP Settings

― The functions available may vary depending on the product model. The color and shape of parts may differ from what is shown. Specifications are subject to change without notice to improve quality

PIP/PBP Mode

Enable or disable the PIP/PBP Mode function.

The PIP (Picture in Picture) function separates the screen into two parts. One source device is displayed on the main screen at the same time the another source device is displayed in inset windows. The PBP (Picture by Picture) function separates the screen in half displaying output from two different source devices simultaneously on the left and right sides of the screen.

• PIP/PBP mode is compatible with Windows 7, Windows 8, and Windows 10.
• The PIP/PBP function may not be available depending on the specifications of the graphics card used. If the screen is blank in PIP/PBP mode when the optimum resolution is selected, go to Control Panel → Display → Screen Resolution and click Detect on the PC. (Instructions are based on Windows 7.) If the screen is blank when the resolution is set to the optimum resolution, change the resolution to 1280 x 1024.
• The screen may flicker briefly or appear after a delay when you enable or disable the PIP/PBP function or when you change the screen size with the PIP/PBP function activated.

This can typically arise when a PC and a monitor are connected to two or more input sources. It has nothing to do with the performance of a monitor.

The issue is mainly caused when the video signals are delayed in transmission to the monitor depending on the graphics card performance.

― To maximize the picture quality, it is recommended to use a graphics card that supports WQHD+ (3440 x 1440) resolution.

― When the PIP/PBP function is enabled, the resolution will not be able to automatically switch to the optimum resolution due to a compatibility issue between the graphics card and the Windows system. Set PIP/PBP Mode to Off. Alternatively, restart the monitor, then set the resolution to the optimum setting using the Windows interface.

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.

The displayed FreeSync menu items on the monitor may vary, depending on the monitor model and compatibility with the AMD graphics card.

― Not available when PIP/PBP Mode is set to On.

― The sound quality of the monitor may decrease if FreeSync is enabled.

• Off: Disable FreeSync.
• Standard Engine: Enable the basic FreeSync functions of the AMD graphics card.
• Ultimate Engine: Enable the FreeSync feature with a higher screen frame rate. Screen tearing (abnormal sync between the screen and content) is reduced in this mode. Note that screen flickering may occur during game play.

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 HDMI2 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 Standard Engine, 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.

― When the resolution is changed while setting FreeSync to Standard Engine or Ultimate Engine, the screen tearing can happen intermittently. 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.

The models in the Graphic Cards list supports FreeSync

FreeSync can only be used with specific AMD graphics card models. Refer to the following list for supported graphics cards:

Make sure to install the latest official graphics drivers from AMD that support FreeSync.

― For additional AMD graphics card models that support the FreeSync feature, visit the official AMD website.

― Select FreeSync Off if you are using a graphics card from a different manufacturer.

― When applying the FreeSync function via the HDMI interface, it may fail to work due to the bandwidth limitation of certain AMD display cards.
