Solve the rough problem of Win2003 playback picture easily

Recently discovered that the Windows 2003 operating system plays a movie, MTV, etc., the resolution is lower, the picture is rougher, the font is jagged, the effect is not as good as Windows 2000 and windows xp, check the graphics card and the driver is also intact. How to solve this?

Now let's take a closer look at the correct settings of the hardware and directx properties. Here's how:

1. Right-click on the desktop and go to “Display Properties ”Window;

2. Click the “Settings" option, and then click the “Advanced” button;

3.Click the <;Troubleshooting” option; Br>

4. Drag the “Hardware Acceleration” cursor to the right to “completely” and click “OK” to exit;

5. Go to “Start → Program &rarr ;Accessories →System Tools →System Information";

6. Click the <quo;directx diagnostic tool" menu item in the <quo;Tools" menu in the Information System window;

7. Select the “Show” tab to enable the “DirectDrw ” and “Direct3D” items.

Well, the work to be done has been completed, the hardware acceleration has reached the maximum, the DirectDraw and Direct3D functions of directx have been enabled, log out of your computer once, and then play and try to see if the image text is rough.

Resolution-related knowledge:

Resolution is a parameter used to measure the amount of data in a bitmap image. Usually expressed as PPI (pixels per inch). The more data you include, the larger the size of the graphics file and the 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, more hard disk space, and more. It doesn't matter, directx will assist the graphics card to help solve these problems.

“Direct” The Chinese meaning is "director, director", DirectX is an interface developed by Microsoft Corporation for hardware programming, including DirectDraw, Direct3D, DirectSound and many other aspects. DirectX technology directly operates on HAL (Hardware Abstraction Layer) to realize video and sound output, network communication, and control of joysticks. There is also a HEL (Hareware Emulation Layer) function in directx to achieve 3D acceleration, so that we can see more beautiful and more realistic 3D scenes and vivid 3D hearing effects.

“DirectDraw”The two-dimensional graphics interface is actually a DDL function, which is the most basic part of DirectX. Its task optimization management is based on the image processing of the window interface, mainly based on 2D desktop and everything based on Plane image processing on top. It mainly deals with the graphics card of the computer, and it uses the multiple data loop of Windows to call the video memory on the display card. With DirectDraw, the display plane is very fast, and for graphics based on the plane, the game can make a big difference. After DirectDraw is enabled, the playback speed of graphic images 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. The importance of DirectDraw is visible. “Direct3D” is a 3D graphics interface, also a DDL function, responsible for 3D scene operations. After Direct3D is enabled, the 3D effect is more obvious, so that the graphic image we see is strong, so the more realistic and beautiful scene effect appears. After installing Windows 2003, the default state of DirectDraw and Direct3D of DirectX is disabled, and the function is not played, so the playback picture is rougher, and the problem of jaggedness of the font appears. To solve this problem, you must pass the correct settings for the hardware properties and directx.
