The PC BIOS configuration screen is not
displayed correctly.

On some PCs, the BIOS configuration screen may not display correctly
because the 58:9 aspect ratio is not supported before the graphics
card driver is configured. This is not a problem of the product; it is due
to the design of the graphics card’s BIOS configuration screen aspect
ratio. To access the PC BIOS configuration screen, please connect a
standard aspect ratio (4:3 or 16:9) monitor, then perform the BIOS
configuration.

When a dark image is displayed on the screen after an image with high
contrast (black and white or gray), this may cause image sticking. This
is normal for LCD screen products.
