显存也是显示卡的重要组成部分，显存也被称为帧缓存，它实际上是用来存储要处理图形的数据信息。我们知道在屏幕上所显现出的每一个像素，都由４至３２位数据来控制它的颜色和亮度，加速芯片和ＣＰＵ对这些数据进行控制，ＲＡＭＤＡＣ读入这些数据并把它们输出到显示器。有一?
Memory is also an important part of the graphics card, memory is also known as the frame buffer, which is actually used to store the data to be processed graphics information. We know that every pixel that appears on the screen is controlled by 4 to 32 bits of data to control its color and brightness. The acceleration chip and CPU control these data. The RAMDAC reads these data and outputs them to the display. One?
