The maximum resolution of the video card

The maximum resolution of the graphics card refers to the number of pixels that the graphics card can depict on the monitor. We all know that the screen displayed on the display is composed of one pixel, and all the data of these pixels are provided by the graphics card. The maximum resolution is to indicate the output of the video card to the display and to describe the number of pixels on the display. . The larger the resolution, the more pixels that can be displayed and the more details that can be displayed, of course, the clearer.

The maximum resolution is directly related to memory to a certain extent, because the data of these pixels are initially stored in the memory, so the memory capacity will affect the maximum resolution. When the memory capacity of the early graphics cards only had a very small capacity of 512KB, 1MB, 2MB, etc., the memory capacity was indeed a bottleneck of the maximum resolution; but the memory capacity of mainstream graphics cards, even 64MB has also been eliminated, the mainstream entertainment level The graphics card is already 128MB, 256MB or 512MB. Some professional graphics cards even have 1GB of video memory. Under such circumstances, the memory capacity is no longer the factor that affects the maximum resolution. The reason why such a large-capacity video memory is needed, It's because large-scale 3D games and professional rendering now require temporary storage of more data.

Now determine the maximum resolution is actually the graphics card RAMDAC frequency, all current mainstream graphics card RAMDAC have reached 400MHz, at least can reach the maximum resolution of 2048x1536, and the latest generation of graphics card's maximum resolution is as high as 2560x1600.

In addition, the maximum display resolution that the video card can output does not represent that your own computer can achieve such a high resolution. It must also have a sufficiently powerful display support to achieve this. In other words, the maximum resolution of the monitor and the display card are also required. The matching of the maximum resolution can be achieved. For example, to achieve 2048x1536 resolution, in addition to the graphics card to support, but also need to support the display. The maximum resolution of a CRT monitor is mainly determined by its bandwidth, and the maximum resolution of a Liquid Crystal Display is mainly determined by its panel. The current mainstream display, 17-inch CRT's maximum resolution is generally only 1600x1200, 17-inch and 19-inch LCD is only 1280x1024, so the current bottleneck in the maximum resolution of ordinary computer systems is not a video card but a monitor. To achieve the maximum resolution of 2048x1536 or even 2560x1600, only with professional-grade large-screen high-end display can achieve, for example, DELL's 30-inch LCD display can achieve ultra-high resolution of 2560x1600.
