User Manual Asus VG32VQ Lcd monitor

Yes. You can choose from 4 types of dots.

Mine came with an HDMI cable and a Display Port cable

No, the screen should be uniform.

Strange, are your resolution settings messed up? I’d double check that in your display options/nvidia control panel (if you’re using that)

Yes. I use the monitor mostly for my xbox series s, it works great for consoles like playstation and xbox.
