how the graphics card works　the data after the CPU processing must undergo the following 4 steps before it reaches the display:1. 　From bus to GPU (graphics processing Unit, graphic processor): The data sent by the CPU is sent to the North Bridge and then sent to the GPU (graphics processing device) for processing. 2. 　Enter video RAM (video memory) from video ch

Graphics view provides an interface that can manage a large number of custom 2D graphical items and interact with them. A view widget can draw these items, it also supports rotation and scaling. The Cabinet also contains an event propagation structure. For these items in scene, it has dual-precision interaction capabilities. Items can handle Keyboard Events, move, release, and double-click events by mouse, or track mouse movements.

　　Graphics hardware installation is only equivalent to the installation of the video card is half done, the driver installation and setup is the other half of the graphics installation. Only when the driver of the video card is installed, all the functions of the display core of the video card will be started, the video card will provide us with the gorgeous picture. before learning the

displayed. When the program first appears in front of us, the program calls the DrawRect: method, gets the graphics context (in memory), and then uses the graphical context to save the drawing information, which can be understood as an area in the graphical context to hold the drawing information, An area is used to save the state of the drawing (line width, fillet, color). The straight line is not drawn directly to the view, it can be understood tha

Use Bumblebee to control NVIDIA dual-graphics card (ubuntu) Introduction Nvidia dual-graphics card switching technology is called Optimus (Optimus Prime), but unfortunately it can only be implemented under win7 and vista. There is no corresponding technology in Linux, and of course Apple does not. This causes the independent video card to be enabled all the time, the video card is heated up, and the fan tur

This type of failure is typically caused by bad contact with the motherboard or a problem with the motherboard slot. For some motherboards with integrated graphics, if the memory is shared with the main memory, you need to pay attention to the location of the RAM, generally in the first memory slot should be inserted in the memory bar. Due to the video card cause of no display failure, usually after the boot issued a long two short beeps (for award BI

A library of 35 JavaScript graphics charts for developersA graph is a graphical representation of data, which means "displaying data through an image of a chart, such as a bar chart, a line chart, and a pie chart." Almost every development or project management team needs charts or graphs to simplify understanding and visualize complex data and Web application workflows. Visualization charts can help developers understand complex D data more easily, i

The most complex part of a video card model should be an English letter after the model. Because it represents that although the video card uses the same graphics core, but the market positioning is different. The most troublesome thing is that the suffixes used by ATI and NVIDIA are not uniform (and cannot be unified), which is dazzling. Le: The suffix of the NVIDIA graphics card model. The full name is "L

In fact, it doesn't matter, just like the headlights of a car can be as far and as near as light. According to different requirements, independent graphics performance is good, but the heat and power consumption is amazing when the battery is very bad, integrated graphics, the current technology has been very good, performance can meet the basic needs, heat and low power consumption of the amazing, the use
