    • Why does the 4K DLP Technology produce a slight high frequency noise?

      In order to create smooth 4K resolution images, True 4K DLP Technology utilizes high speed pixel displacement and the superimposition of pixels to produce the 8.3 million pixels seen by the viewer. An end result of this process is a degree of vibration that may results in a slight or unnoticeable high-frequency noise.

    • Can I turn on the Local Contrast Enhancer or MEMC while watching HDR10+ content?

      When watching HDR10+ content, you cannot enable Local Contrast Enhancer (LCE) at the same time. This is because HDR10+ does not allow additional contrast enhancement functions to be enabled, as they may conflict with other contrast-enhancing algorithms. However, it is okay to enable Motion Estimation and Motion Compensation (MEMC) at the same time.

    • How to watch HDR10+ content?

      If your player and video both support HDR10+, your projector will automatically activate when it receives an HDR10+ format through HDMI. However, if one of the player, video, or projector does not support HDR10+ format, the content will only be played in the standard HDR10 format.
