Compaq monitor auto adjusting


Press the button labeled "Auto" on the front of your Compaq monitor. This runs an automatic configuration utility designed to examine your current settings and adjust them to reach the best possible picture quality.

This utility will take only a few seconds and will adjust things like the sharpness, brightness and resolution of the image being displayed. Press the "Menu" button on the front of your Compaq monitor to adjust your monitor's screen settings manually in the event that the auto configuration utility has not done so to your liking.

Navigate to the "Picture" category of your Compaq monitor's on-screen menu to adjust settings like "Brightness" and "Sharpness." These settings can be useful if your monitor is displaying an image that is fuzzy or too dim.

Use the "Color" setting to adjust the amount of red, green and blue that your monitor displays. These settings can be useful if your monitor is displaying too much of one color or not enough of another.

Use the "Default" menu option to reset your Compaq monitor to its original factory settings. This changes any settings you have altered back to the way they were set when the monitor left the Compaq factory

hope this helps

My laptop screen is bright. Brightness control works but no picture. The picture is ok on external monitor. Sometimes a faint and incomplete picture appears on startup but disappears after a few seconds....


This might be a sign of a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

Sounds like the monitor is going bad. I had this happen too and had to replace the monitor and it's been great since! If you can work fine, it's not the computer itself, it's the monitor.
