C34H890 - No Screen Adjustment Option

[hereisacat]

Hi there, 

I just bought a C34H890 and it's connected to my laptop via HDMI as a secondary monitor. But the laptop screen will not fit the full 34" monitor. Problem is that it used to be able to fit, but I am unable to revert it back. 

My settings are

    - PIP/PBP  > Off

    - Game Mode - Off

    - FreeSync - Off

    - PC/AV Mode  > HDMI AV

    - Picture Size   > only Auto and Wide

I have followed the manual, but still the Screen Adjustment option is grey out. Would be grateful for any help to get the Screen Adjustment option in.

Try checking the display options on the PC itself, check the resolution and aspect ratio for the secondary monitor/screen.
