Maintenance and optimization techniques of liquid crystal display

When you buy a flat panel monitor, you should know that debugging them is completely different from the previous debugging of CRT monitors. If you do not know this matter, then hurry to follow me, step-by-step to adjust their own LCD monitor to the best State bar!

When you buy a flat panel monitor, you should know that debugging them is completely different from the previous debugging of CRT monitors. If you do not know this matter, then hurry to follow me, step-by-step to adjust their own LCD monitor to the best State bar! Although these techniques are mainly for liquid crystal displays, but some of them will also help the CRT, so still using CRT monitor friends, do not lose heart Oh!

Install the latest graphics driver

No matter what type of display you use, your graphics card is often a decisive factor in image quality. So you should first check to see if your graphics driver is the latest version. If not, try upgrading to the latest version of the drive! This is the most convenient and effective way to improve image quality, but also can solve some hardware and software conflicts.

Note: Try not to use Device Manager's Update driver option! It's okay to update drivers for other hardware devices, but it's easy to go wrong when you update the graphics driver. You should browse your video card manufacturer's website and click Downloads or support link to download the latest graphics driver for the corresponding model. Just don't use the beta driver provided on the manufacturer's website. They can cause strange problems to computers when they are at work.

You'd better configure your graphics card with Windows Display properties by right-clicking the desktop space, selecting Properties, and opening the Display Properties dialog box. You'll see a lot of setup options, although this can vary depending on the drive, but all of the graphics drivers offer the following key settings:

Screen resolution: On a CRT monitor, the screen resolution represents the number of pixels that appear vertically and horizontally on your screen, which can be adjusted manually. You can adjust the image quality to increase or reduce the resolution to achieve their own satisfactory results. But these measures do not work well for liquid-crystal displays because the best resolution is fixed. The best way to display a full screen is only when the display mode is set to the best resolution.

Most 15-inch liquid crystal displays have a fixed (physical) resolution of 1024x768, while 17 and 19-inch liquid crystal displays are usually 1280x1024. As long as the resolution is lower than the fixed optimal resolution will result in the LCD will compress the picture to the corresponding size to display or forcibly stretch the image full screen display. When you force a full-screen image, the LCD uses an interpolation algorithm to supplement the missing pixel, which inevitably damages the picture. However, secretly tell you a secret, when you use the fixed resolution of half the mode to display the image, the resulting image will not be compressed deformation, or interpolation algorithm to spend the screen. For example, use the resolution of 800x600 to replace the fixed 1600x1200 resolution.

Even though some liquid crystal displays have the ability to zoom on a fixed resolution basis, and the image displayed is very smooth in this case, you'd better adjust your display resolution to a fixed resolution, which is the best state. How to: Click the settings bar in the Display Properties dialog box and drag the scroll bar below the screen resolution (see Figure 1). If Windows has correctly identified your monitor, the fixed resolution is the highest resolution you can reach by dragging the scroll bar.

Color number: As we all know, the higher the number of colors your monitor displays, the more realistic your image will be. Most PCs support the highest number of color digits typically 32 digits. However, if you find that the image display speed is slowing down (especially if your PC is using RAM as memory, like many low-end integrated display unit PCs), reducing the number of colors will often speed up the machine. You can balance them according to your own situation!

Refresh rate: Many CRT appear screen flicker, this is because the screen refresh rate is set too low (CRT display is the principle of the display through the electronic gun on the screen phosphor repeatedly draw many images, to ensure that the image display, this is called refresh rate). In general, a CRT needs to be refreshed 72 times per second (called 72Hz) to prevent eye fatigue. You don't have to. Set the display resolution to the highest, and you can debug repeatedly to find the best visual resolution, even if it is below the maximum resolution.

For a flat panel monitor, screen flicker is not the reason for the visual effect, because its display principle does not refresh the entire screen like a CRT, just changing the state of each LCD point. For liquid crystal displays, in addition to some very professional LCD monitors, the general refresh rate set at 40 to 60Hz is enough.

Response time: For some liquid crystal display users, especially gamers, may be particularly concerned about response time issues. The display's pixel response time, which is the time when a single pixel color changes from black to white and back to black. Older LCD monitors have slower pixel response times than 20ms, which can cause ghosting and trailing when there are fast moving images on the screen. The majority of the LCD monitors sold today are responding faster than 20ms. But if you're going to buy a flat-panel monitor for a game, it's best to pay more attention to this parameter.

Monitor settings

Whether your monitor is a flat panel monitor or a CRT, don't be afraid to debug the control settings. You debug to make your eyes the most comfortable setting is the best setting, not the vendor recommendation, or friend suggested setting parameters. Usually you can set it by placing a button or knob underneath the monitor.

A flat panel monitor is always easier to debug than a CRT. You hardly need to adjust the visual footage on the LCD screen up, down, left, or right to make sure that the screen displays the full image without the black box. These are the things that often need to be done when debugging a CRT. Many LCD monitors have a button or SET option to automatically adjust and position the image on the screen to full screen display, which is your quickest way to adjust. Of course, if your LCD is set to a fixed resolution, then, in most cases, you will almost not have to do color and contrast debugging.

The following is the most common liquid crystal display in the market settings and debugging methods. Note: Setting the option name for debugging will vary according to the brand and model.
Brightness and contrast: Brightness settings control the brightness of the display backlight lamp. The brightness of a liquid crystal display is always higher than that of a CRT, so there is almost no need to increase brightness. If necessary, you can adjust the contrast by using a grayscale table (some of the displays are randomly supplied), which maximizes the number of visible gray steps. Typically, however, a flat panel displays some distortion when displaying colors at the darkest end of the gradient.

Hue or color temperature: Different light sources emit different colors of white light, from cold green to white to warm red and white. Most displays provide at least three shades or color temperature to adjust colors to normal display under different light conditions. These three types of color temperature may be labeled Mode 1, Mode 2, mode 3 or High, Medium, and low. Manufacturers are also likely to use professional Kelvin (used to detect the color of the hot objects emitting white light) to identify color temperature. The usual settings include a blue-and-cold 9300K, a more neutral 6500K, and a partial red-warm 5000K. Many monitors allow you to manually select the balance between the red, blue, and green primaries in white light. Adjust the settings to see which color temperature is best for you.
