The 120Hz Double Frame Rate Technique Introduction

‧ The 120Hz Double Frame Rate Technique speeds up the image refresh rate from 50/60Hz up to 100/120Hz

by a Motion Estimation and Motion Compensation (MEMC) control circuit to compensate an inter-frame

through the storage and operation method to insert back into its original frame stream for playing. This

technique improves the image dragging and image flickering that occurred from playing motion frames, and

provides viewers smoother motion images.

‧ Operating modes of 120Hz Double Frame Rate Technique

The L2461x Wide Display provides three operating modes:

(1) 120Hz On: Recommended for playing video files at full screen.

(2) 120Hz Off: Recommended for normal PC operating; such as Web browsing or words processing.

(3) 120Hz Split: Recommended for playing video files at full screen. You can clearly see the superiority of

the 120Hz technique.

Q & A

Q: Why the effect of 120Hz Double Frame Rate technique is not obvious?

A: Please check the film standard to see if it is in accordance with the output frequency. Please refer to the

previous paragraph on „Configuring the 120Hz Double Frame Rate.‰

Q: Is it possible to adjust the displayÊs refresh rate up to higher than 60Hz?

A: No. Due to the adoption of 120Hz Double Frame Rate technique, the highest refresh rate can only be adjusted

up to 60Hz.

Q: Why the image flickering occurs occasionally when moving mouse pointer or windows on PC?

A: As the main function of the 120Hz Double Frame Rate technique is to optimize the motion images, and so the

act of moving mouse pointer or windows will be treated and processed as a motion image. That is why the

flickering occurs occasionally. We suggest users to turn on the 120Hz function when watching film, but turn

it off when in regular operation.
