signal cable.
• Access the input menu to check the input signal.

graphics card user manual.
• Check if the graphics card resolution and frequency are supported by
the product. If the frequency is out of range, set to the recommended
resolution in the (Control Panel) → (Display) → (Setting) menu.

• 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.
