Frequently Asked Questions - 24BK55WY LG

How do I connect the monitor to my PC?

Use the appropriate cable: D-SUB for analog, DVI-D or DisplayPort for digital. Connect one end to the monitor and the other to your PC. Ensure the cables are tightened firmly. The monitor supports Plug & Play for automatic detection.

What is the recommended resolution for the 24BK55WY?

The recommended and maximum resolution is 1920 x 1200 @ 60Hz. For optimal image quality, set your PC to this resolution.

How do I adjust the monitor height?

Place the monitor upright. Remove the tape at the bottom rear of the stand body and pull out the locking pin. Then gently lift or lower the monitor to the desired height (up to 130 mm). The pin does not need to be reinserted after removal.

Why is my screen showing 'OUT OF RANGE' message?

This indicates the input signal is outside the monitor's horizontal or vertical frequency range (30-83 kHz horizontal, 56-75 Hz vertical for D-SUB/DVI-D, 56-61 Hz for DP). Check your PC's display settings and set a supported resolution/frequency.

How can I use the Reader Mode?

Press the READER button on the monitor to access Reader Mode. Options include Reader 1 (for newspaper-like text) and Reader 2 (for cartoon-like content). This mode reduces eye strain by adjusting brightness and contrast.

What is SMART ENERGY SAVING and how do I set it?

SMART ENERGY SAVING reduces power consumption using luminance compensation. Press the e0 button to access the menu and select High or Low to enable, or Off to disable. Note: when enabled, Reader Mode is automatically turned off.

How do I clean the monitor screen?

Unplug the monitor. Use a soft, dry cloth to gently wipe the screen. Do not use harsh chemicals, alcohol, or abrasive materials. For stubborn stains, slightly dampen the cloth with water.

Can I mount the 24BK55WY on a wall?

Yes, the monitor supports VESA 100x100 mm mounting. Use a compatible wall mount kit with M4 screws (max length 8 mm from outer surface of back cover). Ensure proper ventilation and follow the wall mount's installation guide.

What should I do if I see 'NO SIGNAL' on the screen?

Check that the signal cable is properly connected to both the monitor and your PC. Ensure the correct input source is selected (press INPUT/EXIT button). If connected, try switching to another input or restarting your PC.

How do I unlock the OSD controls if they are locked?
