This is a feature, not a bug. When using a digital connection (HDMI, DisplayPort, or USB-C), the monitor automatically locks onto the signal with pixel-perfect precision, rendering manual adjustments unnecessary.


Detailed Explanation:

  1. Digital vs. Analog Signals: * Analog (VGA): These signals may require "Auto Image Adjust" to correct image positioning and flickering caused by signal conversion.

    • Digital (HDMI/DP/USB-C): These provide a direct Pixel-to-Pixel mapping. The image is perfectly centered and sharp by default; therefore, manual position and clock settings are disabled to prevent accidental distortion.

  2. What to Adjust Instead:

    • If the image doesn't fill the screen or looks blurry, please check your PC's Display Resolution settings or the Aspect Ratio within the monitor's "Image Adjust" menu.

Important Note:

  • Tip: The "Auto Image Adjust" and "Manual Image Adjust" (H/V Position) features are only accessible when using a VGA (D-Sub) input.
