In fact, because in the previ
High-definition TVs are becoming more common at home, and these high-definition TVs mostly have VGA, DVI, HDMI interfaces. The laptop screen is too small, and most people in the office want an external monitor. So understand the difference between these three kinds of video signal interface, is the premise of choosing suitable display.
1, in advance, the following: Three kinds of connectors have a common n
The difference between a standalone video card and an integrated video card explains one: sharpness is the same, is in the game when the screen is to the core of the graphics card to deal with these images, CPU will need to display the information to the graphics
GDR3, which is a little bit of a note. Anyway, desktop computer graphics card, GDR3 memory type is the slag performance.
6. Video Memory bit width
Video memory bit wide, generally the larger the better, like highways, the wider the road, can pass the vehicle and speed can be faster, so the memory bit width is also a key factor in determining the performance
installed the machine is Pentium 4, right?" ”
There are many friends who have a smattering of hardware, knowledge of the hardware may still remain in the "Ben 4" era, when they choose the video card, will also be to the high-end video card, like 6800XT, 9800Pro and other graphics cards, compared to the past their pri
The video card is a bridge between the host and the display. After the display signal is processed, the video card must send the signal to the display card through the corresponding interface. The video
the solder mask paint (solder masks). It is an insulating protective layer that protects the copper wire and prevents the part from being soldered to the wrong place. A layer of silk screen printing is also printed on the solder mask layer. It is usually printed with words and symbols (mostly white) to indicate the position of each part on the board. The screen printing surface is also known as the Icon Face (legend).3Working principleThe graphics card
inevitably result in data detention. When the data volume is large, the PCI bus will become very tight. The AGP interface is designed to solve this problem. It is a dedicated display interface (that is, boards such as sound card, display card, and video capture card can be

However, some refreshes will prompt you to save the original BIOS file after running, causing the refresh program to not continue. To solve this situation, you can first run the "nv3flash.exe/?" in DOS. command, view its parameters, and add the require

called video card, video adapter, graphics card, graphics adapter and display adapter and so on. It is the connection between the host and the "Bridge", the role is to control the computer's graphics output, is responsible for the CPU sent to the image data processing into the format of the display, and then sent to t

According to the structure of the graphics card can be divided into 2 categories, is often said that the independent graphics and integrated graphics 2 major categories.
Independent video card refers to the display chip, memory and its associated circuit on a single circuit board, self-contained and as a separate board exists, it needs to occupy t
The cause of the video card failure is usually the following
Bad contact. This is due to improper contact with the AGP slot on the motherboard, the general plug in a video card or clean the golden finger part of the video
DxDiag is a diagnostic tool for DirectX that allows you to turn on hardware acceleration for a sound card and video card that supports DirectX.
Click start → run, enter Dxdiag, click OK, and open the DirectX Diagnostics tool.
Switch to the Sounds tab, and in the DirectX feature, change the sound and acceleration level of the hardware to full acceleration.
performance of graphics cards.
At present, desktop computer mainstream graphics card bit width generally reached 128bit, a good number of graphics cards, reached 256bit, or even 512bit. And some entry-level graphics card or entry-level notebook video card, the bit width may still be 64bit, so if you see the graphics
see if the situation has improved. If the video card is used for a long time, if the heat dissipation is poor, the screen may be displayed. In addition, improper memory expansion can easily lead to screen display. It is best to use the same brand, the same speed of memory expansion.4. Focus on the heat dissipation of the video card.Now, the new 3D graphics
HDCP (high-bandwidth Digital content Protection): High bandwidth Digital content protection technology. HDTV (high-definition TV) era is coming, in order to adapt to high-definition TV high bandwidth, there are HDMI. HDMI is a high-definition Digital interface standard that provides high bandwidth, lossless transmission of digital video and audio signals. In orde
, because the graphics driver is incompatible with the program itself or drive the possibility of a bug is indeed very common. For some video cards, you can also try to turn off the AGP quick Write (fastwrites) and the side-band Addressing (AGP sideband) in the motherboard BIOS.
