Fastest
Response Time

Through self-emissive structure with no backlight, Tandem WOLED’s superior response speed is 150 times faster than the previous gaming monitor. (G2G 0.02ms)
* Measured based on 27” 540Hz Tandem WOLED model.

High Refresh Rate
& Low Motion Blur

The Tandem WOLED features an impressive refresh rate* of 540Hz, which ensures smooth screen transitions based on its self-luminous technology. Moreover, the motion blur* phenomenon commonly seen with lower refresh rates is reduced by almost half compared to traditional gaming monitors, resulting in clearer images and more accurate colors.
* Measured based on 27" 540Hz Tandem WOLED model. * Refresh Rate: The number of frames that a display shows on screen in one second. * Motion Blur: A phenomenon where an afterimage remains on the screen when the screen refresh rate is low.

Dual Mode

(540Hz ↔ 720Hz)

Applying DFR* technology, which allows users to freely convert refresh rate and resolution, users can switch between QHD high-resolution mode and 540Hz high refresh rate mode based on the preference.
* DFR: Dynamic Frequency & Resolution * Refresh Rate: The number of frames that a display shows on the screen in one second. * Measured Based on 27” 540Hz Tandem WOLED model.
