LCD TV displays are ideal for use with computers. HP makes a number of liquid crystal display, or LCD, monitors. LCD monitors create an image by passing light through a liquid crystal solution that either blocks the light or allows it to pass through to a color filter. LCD monitors are ideal for use with a computer as they present an excellent still image and cannot suffer pixel burn-in like other flat-screen display technologies. Even quality monitors run into the occasional problem and need some basic troubleshooting before sending them in for service.
Check the power cord to make sure that it is plugged in securely to both the monitor and the outlet. If you are using a surge protector, remove it and plug the power cord directly into an outlet that you know is working.
Detach and reattach both ends of the cable running from your computer to your monitor. If your HP LCD monitor has more than one connector, use the other one to make sure that the connector isn't the issue. Remove any switch or extension cable that may be present between the computer and the monitor.
Restart your computer. A fresh start will correct many software issues.
Check the documentation of your video card to make sure that it supports HDCP, or High Bandwidth Digital Content Protection, since the screen may be blank when you are trying to watch high-definition content through a video card that doesn't support it. Some older HP LCD monitors also do not support HDCP, so check your monitor documentation as well.
Go to your video card manufacturer's website and install the latest drivers for your video card. Instructions for installing the drivers will vary by manufacturer, but they should be listed with the driver software.
Change your resolution to a preset video mode to make sure that you aren't trying to operate the monitor in an unsupported resolution. Different models of HP LCD monitors support different preset video modes. All of the preset video modes for your monitor are listed in your monitor's manual. Resolutions of 1024 x 768 and lower are supported by almost all HP LCD monitors.
Press the "Auto/Select" button on the front of the HP LCD monitor to correct any images that are dark or blurry. If this does not correct the image, press the "Menu" button on the front of the monitor to bring up the on-screen display menu, where you can use the "+" and "-" buttons to scroll through the options and "Enter" to select the option that you want to change. Adjust the brightness and contrast as needed by selecting them and using the "+" and "-" keys. Press the "Menu" button to exit the menu.
Press the "Menu" button to enter the menu, scroll to "Image Control" and press "Enter." From here you can choose the "Auto-Adjustment" option and the HP LCD monitor will automatically adjust the horizontal and vertical positioning to center the screen. The ability to adjust these settings is available only if you are using VGA inputs.
Contact your retailer or manufacturer for any additional troubleshooting steps for your particular model of HP LCD monitor. If your monitor still has issues, you may need to send it in to be serviced.
