For lovers of cinema, modern technology provides ample opportunities to comfortably watch your favorite movies. Yes, you can use a computer monitor for this purpose. However, if you have a modern, widescreen LCD LCD or plasma TV, then the temptation to turn it into an additional monitor will be great. Moreover, this task is quite feasible.
Monitor and TV: pluses and opportunities
The computer and the TV are connected using a cable specially designed for this purpose. This will allow not only to get more pleasure from entertainment (movies, games, Internet), but also to work. The TV screen will become a lifesaver for owners of compact electronic devices: tablets, netbooks. Two high-tech devices connected together will allow, for example, to watch movies in HD or Blu-Ray quality, photos, slides, to work on the Internet. However, the connection may cause technical malfunctions. One of the most common and frequent problems is that there is no sound on the TV through the HDMI cable connected. Consider options for how to cope with the task.
Connectors and cable
Before connecting, both devices must be turned off and turned off. This is to ensure safety. The computer and the TV have almost the same jacks for the HDMI cable, and they are located on the back of each device. In a PC, the cord is inserted directly into the video card, there are other options. For example, it can connect directly to the motherboard, and the connector is located next to the USB ports. The cable may have different lengths. Both ends have identical connectors. When buying, you can choose and not very expensive, Chinese-made. However, if you are going to run voluminous files and watch high-quality video (for example, in 3D format), you will need a more expensive and high-quality cable. HDMI version 1.4 or higher is suitable. When connecting, some difficulties may appear. Before moving on to the problem when there is no sound on the TV via an HDMI cable, consider another important issue: options for connecting it. To ensure a comfortable viewing of your personal video library on a new LCD or plasma TV, you need to consider where the receptacles for the cord are located on the receiving device. For a TV that hangs on the wall, a cable with a plug, which is at an angle of 90 °, is purchased. If there are not enough ports, then an adapter is required. The switcher will help to connect several devices through one port.
Image adjustment
Before you adjust the sound via HDMI, you need to adjust the image on the TV screen. First, PC and TV are connected by DVI cable, and then HDMI. The message “Cable not connected” or “Weak signal” appears on the screen. Additional settings are available through the remote. On it, you need to click the "Source" button and determine the device transmitting the signal. A menu will appear on the TV screen, in it you must select the port to which the computer is connected. Further, in the "Image Settings" on the screen the optimal resolution is set. Sometimes, when setting up a connection between two devices, you need to adjust the incoming sound to the TV via an HDMI cable. It should be borne in mind that both video and audio signals come through it. Therefore, the setup may fail.
Sound setting
Having completed all the steps described above, you can display the image from the computer to the TV. However, sometimes there are failures when connecting. The problem of how to connect sound via 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). To check it is worth a look in the "Device Manager" in the "Control Panel". There you need to select the cursor "Sound, gaming and video devices." In the list, click on the line denoting support for sound in HD format. When the TV is connected to the computer, the device will change the status to Ready. Right-click on it and select "Use default" in the drop-down menu.
Other connection errors
When adjusting the image, the optimal resolution is set that matches the characteristics of your TV model. Now you have a beautiful picture on the screen, but the question that there is no sound on the TV via HDMI may not lose its sharpness. How can it be solved? The mouse cursor must click on the "Start" button, select "Control Panel" in the menu. In the computer settings, go to "Hardware and Sound", then click "Sound". If it is not available on your computer, you need to click on the empty space with the mouse. In the pop-up menu, select "Show connected devices" or "Disconnected devices". In the window, select the name of the brand of the TV. Now it should be turned on and off unnecessary devices (that is, a computer). For the last operation, you need to right-click on the button labeled Realtek and select "Off" in the menu that appears. In the same way we will do with "Speakers". If there is no sound on the TV via HDMI, just follow all the steps above and then, of course, you can enjoy watching the video in full.
