By watching the video from a laptop, there are three elements that appear on the following: screen size, resolution, and the graphics processor. For most people, only the screen size and resolution is all that really matters. The GPU is really only tend to make a difference for those who can make some games for mobile devices and high-definition video to make. Almost all laptops use some type of active matrix display with backlight for brilliant displays enable fast video playback capable.
Screen Size

Notebooks with screens of different sizes, depending on the type of portable computer systems, you are viewing. large screens offer a simple on-screen display, as desktop replacement. Ultra Mobile tend to have smaller screens, smaller size can be increased for portability. Many systems offer a wide aspect ratio for cinema screen or the screen size to increase in depth, to a smaller size of the system.

All dimensions on the screen diagonal. It is measured in the bottom of the screen to the opposite corner of the screen. This is the actual area should be clearly visible. Here’s the schedule of medium size screen for laptop computers, another style

  • Netbook: 12 “or less
  • Ultra: 13,3 “or less
  • Thin and lightweight: 14 “to 16”
  • Desktop replacement: 17 “to 19”
  • Luggables: 20 “and more


Screen resolution and native resolution, the number of pixels on the screen in the list number on the screen by the number of the bottom of the screen. The laptop shows look better if the graphics to work in this native resolution. While it is possible to lower resolution, or run as a preview image is extrapolated to the screen with black borders or a statement. Projected screen usually leads to a decrease in image sharpness, as the system for use by a few pixels, try to show as one pixel typically appear.

High native resolution to provide more information in the figure, and more working space on the screen. The downside of high-resolution screen that sources will be less inclined to read and harder. This can be a particular disadvantage for people who have vision problems. There may be offset by the operating system by changing the font, but it can lead to undesirable results in the programs. The following table shows the various reductions videos that relate to the decision:

  • WVGA: 800×480
  • SVGA 800×600
  • WSVGA: 1024×600
  • XGA 1024×768
  • WXGA: 1366×768 or 1280×800
  • SXGA: 1280×1024
  • SXGA +: 1400×1050
  • WXGA +: 1440×900
  • WSXGA +: 1680×900 or 1680×1050
  • UXGA: 1600×1200
  • WUXGA: 1920×1080 or 1920×1200

Graphics Processor

In the past, graphics processors, was not a big problem for compact PCs. Most users are more necessary to clearly accelerate 3D-graphics or video. This proved to be more and more use of their laptops on the computer have changed entirely. Even if you do not plan to play computer games, the GPU is still a necessary element, if you want HD movies either on the current playing media file, or Blu-Ray. can work with most modern graphics processors dedicated to this, but if you’re looking to play 3D-games, you should look in the direction of mobile graphics.

The two most important supplier of graphics processors for notebooks from ATI and NVIDIA. ATI has a supply of graphics processors for notebook PCs for many years, and reputation in terms of energy supply graphics chips more powerful and more efficient. NVIDIA graphics engine of the desktop, when it comes to 3D-accelerator comes and were the first to bring many of these characteristics on the field notebook.

The following chart shows the current crop of mobile graphics processors, the two companies. They are listed in approximate order from highest to lowest yield. Notebooks are designed for games, at least not less than 256 MB of dedicated graphics memory, and, most likely. (Note that this list is only a short version of the latest graphics processors are several models of the previous generation).

  • NVIDIA GeForce GTX 480
  • ATI Mobility Radeon HD 5870
  • NVIDIA GeForce GTX 280 million
  • ATI Mobility Radeon HD 5850
  • ATI Mobility Radeon HD 4870
  • ATI Mobility Radeon HD 5770
  • NVIDIA GeForce GTS 360M
  • NVIDIA GeForce GTS 260M
  • ATI Mobility Radeon HD 5750
  • NVIDIA GeForce GTS 350M
  • NVIDIA GeForce GTS 250 million
  • ATI Mobility Radeon HD 5650
  • ATI Mobility Radeon HD 4850
  • NVIDIA GeForce GT 330
  • NVIDIA GeForce GT 240
  • ATI Mobility Radeon HD 4670
  • ATI Mobility Radeon HD 4650
  • NVIDIA GeForce GT 320M
  • ATI Mobility Radeon HD 5400
  • ATI Mobility Radeon HD 4570
  • ATI Mobility Radeon HD 4530
  • ATI Mobility Radeon HD 5165/5145
  • NVIDIA GeForce 310M
  • ATI Mobility Radeon HD 4330

In addition to these processors from ATI and NVIDIA, both technologies allow that some graphics processors operate at two, can improve performance. ATI CrossFireX technology, known as NVIDIA SLI. Although the figure above, the battery life for laptops, since they greatly reduce further energy consumption
