The power saving states will be kept until a control signal has been detected or the keyboard or mouse is activated. The recovery time from Active OFF state back to ON state is around 3 seconds.

DDC

To make your installation easier, the monitor is able to Plug and Play with your system if your system also supports DDC protocol. The DDC (Display Data Channel) is a communication protocol through which the monitor automatically informs the host system about its capabilities, for example, supported resolutions and corresponding timing. The monitor supports DDC2B standard.

Overclocking for DisplayPort only.

EN-8

Note: The DisplayPort of this monitor is purposely supporting the G-Sync compatible/Adaptive-Sync support technology. This technology allows Adaptive-Sync (DP) supported graphics source to dynamically adjust display refresh rate based on typical content frame rates in order to eliminate stuttering and enhance low-latency display.

Note: Overclocking may result in flicker or other adverse effects that may derive from the total configuration of the system connected to the display, and possibly, in addition, the display’s panel specifications. It may be possible to resolve or reduce such effects by setting a lower refresh rate.
