The Windows 2003 operating system is much more powerful than Windows 2000 and Windows XP in terms of performance and resource management. However, after installing Windows 2003 and graphics card drivers, the resolution is lower, the picture is rough, and the font is serrated. The effect is not as good as Windows 2000 and Windows XP. It is also good to check the graphics card and drivers. So is it just asserting that Windows 2003 is not as good as Windows 2000 and Windows XP when playing movies, MTVs, etc.? In fact, this is not the case. If you understand the meaning of resolution and understand the "DirectDraw" and "Direct3D" functions of DirectX in Windows 2003, then you can get clear playback images and gorgeous colors through correct settings.
Resolution is a parameter used to measure the amount of data in a bitmap image. It is usually expressed as PPI (pixels per inch). The more data it contains, the larger the size of the graphics file and can also express richer details. Therefore, the higher the resolution, the higher the sharpness of the image, and the more realistic it looks. But larger files also require more computer resources, more RAM, greater hard disk space, etc. It doesn't matter, DirectX will assist graphics cards to help solve these problems.
The word "Direct" means "commander, director" in Chinese. DirectX is an interface for hardware programming developed by Microsoft, including DirectDraw, Direct3D, DirectSound and other aspects. DirectX technology directly operates HAL (Hardware Abstraction Layer), realizing the output of video and sound, network communication and control of joysticks. There is also a HEL (Hareware Emulation Layer, hardware simulation) function in DirectX, which realizes 3D acceleration, allowing us to see more gorgeous and realistic 3D scenes and vivid 3D auditory effects.
"DirectDraw" is a two-dimensional graphical interface. It is actually a DDL function and is the most basic part of DirectX. Its task optimization management is based on the image processing of the window interface, mainly 2D desktop and all-based flat image processing. It mainly deals with the computer's graphics card, and it will use Windows' multiple data circulation to call the graphics memory on the graphics card. With DirectDraw, the speed of displaying planes will be very fast, and there will be great changes for graphics and games based on planes. With DirectDraw enabled, the playback speed of the graphics image is significantly faster, so the more pixels per inch per unit time, the higher the resolution, the clearer the image, and the smoother the text. It can be seen that the importance of DirectDraw lies. "Direct3D" is a three-dimensional graphical interface, which is also a DDL function, responsible for 3D scene operations. After enabling Direct3D, the three-dimensional effect is more obvious, making the graphics we see strong three-dimensional sense, and then a more realistic and gorgeous scene effect will appear. After installing Windows 2003, DirectX's DirectDraw and Direct3D default states are disabled and do not perform their functions, so the playback screen is relatively rough and the font has serrated problems. To resolve this problem, it is necessary to make the correct settings for hardware properties and DirectX.
Now let’s introduce the correct settings of hardware and DirectX properties in detail, as follows:
1. Right-click on the desktop to enter the "Show Properties" window;
2. Click the "Settings" option, and then click the "Advanced" button;
3. Click the "Troubleshooting" option;
4. Drag the "Hardware Acceleration" cursor right to "Full" and click OK to exit;
5. Enter "Start → Programs → Attachments → System Tools → System Information" in turn;
6. Click the "DirectX Diagnostic Tools" menu item in the "Tools" menu in the information system window;
7. Select the Display tab, enable the DirectDrw, and then enable the Direct3D items.
OK, now the work to be done has been completed, the hardware acceleration has reached maximum, DirectX's DirectDraw and Direct3D functions have been enabled. Log out of your computer once, and then play to try to see if the image text is rough.
