Laptop Chargers and TV batteries

Watching TV is a good idea. Laptops can be used to watch tv. To charge a laptop it is important that laptop chargers.

For some time I have watching my 32 "TV and think, why not connect the PC to the TV and play my favorite games on the big screen? Do you feel the same?

Well, I decided to do, but there are some limitations that ultimately may make it not worthwhile. I'll explain later in this article.

1 .- Identify your TV inputs
Most TV take 3 basic connections. They have the coaxial cable (antenna), RCA Composite video, connectors that are red, yellow and white and S-Video. Currently, almost all also include VGA, HDMI, Component and DVI.

2 .- Identify the outputs on your computer.
Currently, manufacturers are adding more and more outlets for TVs, making it easier to connect to other computers. The S-Video in particular seems to be gaining ground in more and more computers. Mostly you'll find the usual VGA out, where normally connect your monitor. Currently many TVs have VGA inputs makes it easy to use as a PC monitor, but we will focus on the connection on television not so new, that are in greater proportion than we found in homes.

3 .- I'll find the right adapter for your connections.
You may need to buy an adapter or breakout box to connect the PC to the TV. They consist of an adapter that on one hand has a VGA input, which connect the PC, and a series of outputs, S-Video, RCA or Component). We recommend purchasing one of these adapters, but it's the wireless feature, since it is much more comfortable at the time of installation and thus can connect without having the PC near the TV.

4 .- Connect your computer to the television.
If you have a connection on your TV that is compatible with any of the outputs on your PC, connect them directly. If you do not have available, connect through the junction box that we discussed earlier the VGA on your pc and then connect the RCA cables, S-Video or Component to the TV. Turn on the television and computer and select the TV channel you've selected the connection to see the screen image.

Now is the time when you may feel somewhat disappointed.
The video signal the TV is called PAL (NTSC if you live outside Europe). This signal differs from that generated by the PC. Computers use resolutions that are measured in pixels: 320x200, 320x240, 640x480, 800x600, 1024x768, 1280x1024 or 1600x1200. Most TVs are only capable of displaying 500 lines of resolution, the equivalent of 500 vertical pixels on a PC. You can not select a higher resolution on these TVs, so we can enjoy the most that is a resolution of 640x480px.
Nor is it the worst in the world, you can play and watch videos in low resolution without problems, but for now you can not have video quality that makes the usual PC monitor.
This problem was corrected in most current plasma TVs or LCD, as native connections include VGA or HDMI, which provide high resolution without having to acquire any other adapter.
