Monitor and TV: the pros and cons

The screen of the television receiver will become a "wand-receiver" for the owners of compact electronic devices: tablets, netbooks. Two high-tech devices connected together allow, for example, to view movies as HD or Blu-Ray, photos, slides, work on the Internet. However, when connected, technical malfunctions may occur. One of the most common and common problems is that there is no sound on the TV, through an HDMI cable connected. Consider options for how to cope with the task.

Connectors and cable

Before connecting, both devices must be switched off and de-energized. This is done to ensure safety. The computer and the TV have almost identical sockets designed for the HDMI cable, and they are on the back of each device. At the PC the cord is inserted directly into the video card, there are other options. For example, it can be connected directly to the motherboard, and the connector is located next to the USB-ports. The cable may have a different length. At its both ends the same connectors. At purchase it is possible to choose and not so expensive, the Chinese manufacture. However, if you are going to run large files and watch high-quality video (for example, in 3D format), you will need a more expensive and high-quality cable. Suitable HDMI version 1.4 or higher. When connecting, you may experience some difficulties. Before proceeding to the problem, when there is no sound on the TV through the HDMI cable, let's consider another important question: the options for its connection. To ensure a comfortable viewing of a personal video library on a new LCD or plasma TV, one must take into account where the receptacle houses the jacks for the cord. For a TV that hangs on the wall, you purchase a cable with a plug that is at an angle of 90 °. If there are not enough ports, then an adapter is needed. The switcher helps to connect several devices through one port.

Image adjustment

Before you can adjust the sound through HDMI, you need to adjust the picture on the TV screen. First, the PC and TV are connected with a DVI cable and then HDMI. "Cable not connected" or "Weak signal" appears on the screen. Additional settings are available through the console. On it, you must press the "Source" button and determine the device that transmits the signal. A menu appears on the TV screen, in which you must select the port to which the computer is connected. Next, in "Image Settings", the screen displays the optimal resolution. Sometimes, when setting up a connection between two devices, you need to adjust the incoming sound to the TV via an HDMI cable. It must be taken into account that both video and audio signal is input through it. Therefore, the settings may fail.

Having done all the steps described above, you can display the image from the computer to the TV. However, sometimes crashes occur during connection. The problem of how to connect audio through HDMI can occur if drivers are not installed on the video card (as a rule, they are installed from the disk that is purchased with the computer). For testing, it's worth checking out the "Device Manager" in the "Control Panel". There you need the cursor to choose "Sound, game and video devices". In the list, click on the line denoting the support of audio in HD format. When the TV connects to the computer, the device will change the status to "Ready".
