In the real world, buildings were built at least in the 1980s S, and are generally not designed for the cabling requirements of the Information Age. Cabling slots and channels are generally crowded. Cables required to support high-definition videos (VGA or XGA at least) (for example, coaxial cables connected at the top of a 5 BNC connector or

do not pay much attention to the wide screen resolution supported by integrated graphics cards, so they have not updated the BIOS. What should I do if I encounter such a problem? You can use CBROM to create one by yourself. For ease of operation, I renamed them old. Bin (wide screen resolution not supported) and new. Bin (wide screen resolution supported ). The operating principle is to use CBROM (the latest version is 2.19) to extract the VGA (displ

On the Internet, I went around randomly. Some of my friends said they could watch a movie under a character. I also wanted to try it! It's easy. Here we just record the process and Configuration: 1.

Driver Installation: The installation of a new video card driver is not perfect, that is, when the system is started, there is no visual pattern of the Progress circle, and it is very likely that the resolution can be properly displayed only by force modification, however, after the video card driver is installed, you can use the desktop special effects (Very dazzling) that come with the system. The default noveau has a visual progress circle, and the resolution is not normal. You can also force

From: http://bbs.dospy.com/thread-6036281-1-1.html Our commonly used mobile phone screen uses the same LCD screen as the notebook, the resolution of the LCD screen is fixed, each point is a pixel. In addition, the cell phone resolution does not refer to the screen size, and it can be said that it has nothing to do with the screen size.For example, a 2.1 inch LCD screen can display an image of 240x320 resolution, which is called a "qvga 2.1 inch LCD screen". A 3.8 inch LCD screen can display

My laptop is ThinkPad, and the external display is set to 1680x1050. First, familiarize yourself with the command: The xrandroid command line allows you to easily switch between two screens.

The Xrandr command line makes it easy to switch between two screens, often in the following ways:Ubuntu commandXrandr--output VGA--same-as LVDS--autoTurn on the external monitor (highest resolution) and display the same content as the laptop LCD screen (clone)Ubuntu commandXrandr--output VGA--same-as LVDS--mode 1024x768Turn on the external monitor (1024x768 resolution) to display the same content as the lap

This situation, is not the monitor is the reason for the video card, so the main is to address these two aspects, the driver or software, the possibility is very little, anyway, I personally did not encounter this problem. If the feeling is a software or driver problem, you can open the machine into safe mode. 1th Step: Monitor VGA data line loose or bad contact. Check the computer host behind the display of the
