Graphics card installation and debugging methods

　　Graphics hardware installation is only equivalent to the installation of the video card is half done, the driver installation and setup is the other half of the graphics installation. Only when the driver of the video card is installed, all the functions of the display core of the video card will be started, the video card will provide us with the gorgeous picture. before learning the graphics driver settings, let's answer two common questions:

Q: Why does the desktop appear normal, but just can't play the game?

A: In Windows, there will be some video card drivers, but these drivers only bring the lowest level of 2D display, so the desktop display is not a problem, but need 3D function of the game is not. Therefore, the driver provided by the video card manufacturer must be installed.

Q: Why is there no tuning after the graphics driver is installed?

A: Some video card drivers and adjustment-driven Control Panel are installed separately, so to start the adjustment function, in addition to installing the driver, but also to install the driver Control Panel.

Currently on the market ATI and nvidia two independent video cards occupy an absolute advantage, this period we will introduce the ATI video card driver installation settings.

ATI graphics driver features and installation

With the introduction of the "Catalyst (Catalyst) 2.1" drive, ATI has reversed its previous drive to update slow bugs and many other diseases. The driver has been able to do a one-month update to fix the compatibility bugs and improve the performance of the video card that existed between the previous drive and the new video card. At present, its latest "catalyst" driver version has been made 4.9, and the Integrated Control Panel also includes the Catalyst Control Center, "CATALYST control Centers" and the general controller panel of the two versions, we still use a wider range of common control Panel for example.

If you are installing a new video card, it is best to install the system default VGA driver before installing the driver, then install DIRECTX9 (recommended DIRECTX9.0C International, add support for ATI 3DC texture compression technology, and fix some other minor bugs, download address: http:// www.mydrivers.com/dir95/d38285.htm), finally installed 4.9 version of the driver can be (recommended to download the installation of the Integrated General Control Panel version 4.9, download address: www.mydrivers.com/dir99/d39922.htm).

ATI Graphics Driver Tuning

After the driver is installed and the control Panel, the right mouse button clicks on the display desktop, left-click "Properties" to enter the "Display Properties" Adjustment interface, select "Set → advanced" in the interface, and enter the "graphics properties" to adjust the interface. The adjustment interface has "ATI Options", "ATI Rotation", "ATI Overlay", "Smartgart", "ATI display", "ATI Color", "3D", "Vpu Recover", "Overdrive" and other graphics Control Panel tabs. We can according to the function of these settings are divided into: graphics information supply, output equipment selection adjustment, 3D function adjustment, special functions to achieve 4 types of settings. Here are some of the key settings.

1. Video card information provided

In the ATI Options tab, we can learn about the display-driven version number (Figure 1).

Click on the "Details" button in the tab to more clearly understand the video card core model, memory model, BIOS date, manufacturer code, such as the internal information of graphics cards to facilitate users to see the real graphics card model, you can avoid profiteers by modifying the driver, deceive the user's situation. Additional information needed to upgrade the graphics BIOS and install vendor-customized drivers is also known here (Figure 2).

In addition, there are several practical features in the ATI options, such as "Disable fast resolution feature", and check the options to solve the problem of some resolution and refresh rate of the monitor. The "Reduce the DVI frequency of high resolution displays" applies to liquid crystal displays, it is known that the LCD refresh rate is low (generally 60~75hz), such as the original system set the resolution and refresh rate is very high, then the DVI interface of the LCD monitor connected may not work or show abnormal, The problem can be resolved by simply checking the "reduce DVI frequency of high resolution displays".

The Smartgart tab is able to understand the performance of the AGP feature of the video card (Figure 3).

Smartgart is ATI with Catalyst (catalyst)-driven release of a video card gadget, by automating the PCI/AGP bus test to determine whether the user's video card settings are normal to ensure the stability of the system. Slide the "Set AGP Speed" slider to adjust the speed of the AGP, you can set the AGP speed directly here, but if the ATI Smartgart think the current setting is not correct, it will automatically change your settings. Fast write can be turned on or off in the fast write entry below, the quick Write feature allows the CPU to send data directly to the video card without memory, to speed up the graphics card, and most test results show that this mode is more effective for improving the performance of the graphics card. However, some systems may also cause performance degradation when this feature is turned on. In addition, if your system already has an unstable factor, you can turn off fast write to try.

2. Output Equipment Selection adjustment

The ATI Display option adjusts the screen position and screen size of a single display and multiple display devices, and adjusts the current screen resolution and refresh rate information for the display (Figure 4). If you install a second display device or TV, clicking the ① button on the device also enables and disables these display devices. For example, you can watch a DVD movie or play a game on a large-screen TV by simply connecting an AV cable or an S-terminal line from the video output connector to the corresponding input interface of the TV. and select the "TV" button, you can adjust the TV screen definition and video format, etc., so that your video graphics output the best results. If your video card and display support color difference input and output this high-definition display mode, and have the corresponding connection line, we can also here selected YPbPr, using color difference output, experience a higher TV output effect.

To use dual display devices for dual-head display, you can go to the Display Properties adjustment screen, click on the second monitor that you want to expand your desktop on, adjust the resolution, and place a check mark in the box on the "Extend Windows desktop to this monitor", "OK" in the "ATI display" Options you need to do as the main display of the selected "1", will be as a secondary display of the selected "2", can be in two display devices on the division.
