【 Weak current College 】 video maximum resolution

Maximum resolution of the video is the video on the monitor is able to depict the number of pixels. We all know that appear on the monitor screen is one pixel of dots, and these points, all data is provided by the video card, the maximum resolution is that the video output to the monitor and monitor depicts the number of pixels. The higher the resolution, it can display images, the more pixels and can display more details, of course, the more clear.

Maximum resolution, to some extent, have a direct relationship with video memory, because the pixel data is initially stored in video memory, so the video memory size affects the maximum resolution. In the early days of video memory size simply 1MB with 512 KB, and so on very small, 2MB capacity, memory capacity is the maximum resolution of a bottleneck; but now the mainstream video card RAM, even 64MB has been eliminated, mainstream entertainment-class video card is already a 128MB, 256 MB or some professional graphics 512MB, even with 1 GB of graphics memory, in this case, the video memory capacity influence early is no longer a maximum resolution of factors that need such a large amount of video memory, but that is because of the large 3D gaming and professional rendering needs to temporarily store more data.

Now decide the maximum resolution is the video of the RAMDAC frequency, all mainstream video card has reached the RAMDAC 400MHz, at least in order to achieve the maximum resolution 2048x1536, and the latest generation of graphics cards, the more is the maximum resolution of 2560 x 1600.

In addition, the video card can output the maximum display resolution does not mean that your PC can achieve such a high resolution, you must have enough powerful monitor supporting can achieve, that is, you also need a monitor's maximum resolution and the video card to match the maximum resolution can be achieved. For example, to implement the resolution, in addition to 2048x1536 video card must support, you need to monitor and to support. Instead of a CRT monitor's maximum resolution is largely determined by their bandwidth, and the LCD monitor's maximum resolution is mainly determined by the Panel. Now the mainstream monitor, 17-inch CRT its maximum resolution generally only 1600x1200, 17 inches and 19 inches LCD only, so at present in 1280x1024 general computer system on a maximum resolution of bottlenecks is not a graphics card and monitor. To achieve the 2048x1536 even 2560x1600 maximum resolution, only with the help of professional-grade large-screen high quality monitor is required to achieve such as DELL's 30-inch LCD can achieve 2560x1600 of ultra-high resolution.
