SDRAM is still in use in the memory, although the subsequent DDR replaced, it is important to master it. Before debugging, it really cost a great effort, its complexity is undoubtedly, the general people want to understand him, it will take about 1 months, at least I think so. What is the role of SDRAM, anyway? The answer must be storage, if you do not use it in the project, it is difficult to appreciate the role of it, recently in the SDRAM VGA displ

In fact, your tty1 ~ In addition to the 80x24 Resolution, tty6 also supports other resolutions! However, the premise is that your core must support the core function option framebuffer_console. How can I determine whether it is supported? You can check the/boot/config-2.6.18-92.el5 file and search like this:

resolution in the market has two main indicators: 1920x1080, 1366X768. For example, the physical resolution of 1366X768 indicates that its imaging device has 1366X768 pixels. At the same time, pixels are also the basic units of the image. A 1920x1080 resolution image indicates that the image consists of 1920x1080 pixels. Only when the resolution of an image or signal source is exactly the same as the physical resolution of the TV can their pixels be mapped one to one (point-to-point display ),
, there are different things to consider. One is to consider objects that follow interface rules, and the other is to consider instances of specific classes.
The interface is more flexible, and the implementation function is also relatively simple. The specific class can implement the function and provide some additional information.
For example, there are three PC output signal modes: VGA, DVI, and HDMI (and many other modes ). The company has a
Neuros OSD is a digital video recorder that can automatically encode analog videos and DVDs as digital signals and store them or play them on TV.It does not carry memory, but can store programs to SD/MS/MMC/CF flash cards or mobile hard drives connected through USB interfaces.Based on the Linux system, firmware is fully open-source and has a wide application space.It can be used to record programs of different resolutions based on playback devices (such as PSP game consoles, apple, TVs, and tele
The following uses the Computer VGA 13 H video mode as an example to systematically introduce the basic methods for making computer games. Vga int 13 H mode is a mode that works in graphics mode. It has a screen resolution of X, 256 colors can be displayed on the same screen (Super Nintendo and Sega's 5-generation game consoles only have 256 colors ), many early games were developed using this graphic metho
The Windows 2000 boot menu has become a very useful diagnostic tool after the previous version of the renovation, providing more complete troubleshooting functions than the previous versions. The original purpose of the security mode is to allow users to enter the operating system with the lowest configuration to remove the cause of system failure. Therefore, CD-ROM, network, and printer connections are not supported, however, compared with Windows nt vga

the above figure shows a real shot. One is a 15-pin VGA mother head and the other is a 24 + 1 DVI. currently, many graphics cards do not have VGA interfaces, especially high-end graphics cards, which are equipped with DVI interfaces, some interfaces are a VGA interface and a DVI interface. Some interfaces are simply dual DVI interfaces. If you want to use dual
The Windows 2000 Startup menu has become a very useful diagnostic tool after previous versions of renovations, providing more complete troubleshooting than the previous versions. Safe mode is intended only to allow users to enter the operating system at a minimum configuration to remove factors that cause system failure, so it does not support CD-ROMs, networks, and printers, but Windows NT VGA mode Mode offers a lot of handy features.

Workaround:
First check the video card is normal installation, if the display is pulling the VGA line shadow changes, that is, VGA data line contact is not good, obviously this problem on the VGA line, changed the root of the VGA line, the problem is solved.
