Monitor ACER Predator XB323QKNV Black bars Left, Top and Right.

StuartDD

Hi. Just setting up my monitor and I have noticed black bars at the Left, Top and Right of the screen.

I had them when I initially set up the monitor but yesterday after changing HDMI leads they were not shown.

Today they are back and i do not know what caused this.

I have also connected an Acer Chromebook via the provided USB-C and the the black bars are shown there as well.

I notice that I can just see the glow from the display and the black bars are still there even when there is no display selected and the screen is black. The bars are just visible.

Can you please help

What about when the Acer splash screen is displayed when you first turn the monitor on?

Hi

Thanks for replying

Yes it is there when the splash screen is shown

If they display during the splash screen then we know it's a problem with the monitor and not the cable or on the computer side of things. So, are you still in warranty?
