Frequently Asked Questions - LA1956x COMPAQ

What is the native resolution of the Compaq LA1956x monitor?

The native resolution is 1280 x 1024 (SXGA) with a 5:4 aspect ratio.

How do I connect the monitor to my computer?

Use the supplied VGA or DVI-D cable. Connect one end to the monitor and the other to your computer's corresponding port.

My monitor shows 'No Signal' on screen. What should I do?

Check that the video cable is securely connected at both ends. Ensure your computer is powered on and outputting to the correct input source. Try switching between VGA and DVI using the OSD menu.

How do I adjust the screen brightness and contrast?

Use the buttons on the front bezel to access the On-Screen Display (OSD). Navigate to 'Brightness' or 'Contrast' and adjust using the arrow keys.

Can I mount this monitor on a wall?

Yes, the monitor supports VESA 100 x 100 mm mounting. Use a compatible wall mount bracket and follow the instructions provided with the bracket.

What cleaning products are safe for the screen?

Use a soft, dry, lint-free cloth to gently wipe the screen. If needed, slightly dampen the cloth with water. Do not use alcohol, ammonia, or abrasive cleaners.

My monitor has a stuck pixel. Is this covered under warranty?

Most manufacturers consider a few stuck pixels as acceptable. Check your warranty terms. For the LA1956x, contact Compaq support if you have more than 5 bright or dark pixels within the standard acceptable range.

How do I reset the monitor to factory settings?

Access the OSD menu, navigate to 'Setup' or 'Other', and select 'Factory Reset'. Confirm the reset to restore default settings.

What is the power consumption of the monitor in standby mode?
