I know HDMI can synchronize output images and sounds, DVI and VGA can only image, can not make sound. My question is, if I use HDMI to connect the host and the TV, then can the computer sound through the TV stereo or some audio monitors? Because HDMI is not connected graphics card, the sound is issued from the sound card, right? No DIY, although some understanding of the computer, but did not carefully study the assembly machine, so ask. If the video card input image is transmitted to the TV via HDMI, how can the audio of the sound card be transmitted? Do you still need an external audio interface to connect the host to the 3.5mm? If so, what's the difference between HDMI and VGA? Thank you for your careful answer, thank you!
First of all, HDMI connected to LCD TV, there is no need to connect to the audio, TV can release the sound of the computer!Secondly, the connection with the speaker of the monitor may not be able to release, because the monitor does not necessarily bring HDMI audio decoding, usually through the 3.5 connector access to the computer!And HDMI line can transmit audio and video at the same time, but the mode of transmission is not analog transmission, but is transmitted in digital way, then it is passed and decoded later! Video card has HDMI interface, that is because the HDMI card has been integrated with digital audio processing system, can also be understood as a video card with a sound card! If you drive the graphics cards, you can find them in the device manager's audio options! It just doesn't simulate output! Hope to adopt!
There is no need for external audio, because the HDMI connection can transmit both audio and video signals at the same time. Computer host and LCD TV using HDMI connection method is as follows:1, the computer and TV must have HDMI interface, as shown:2, you need to prepare a HDMI connection line;3, HDMI connector with one end of the plug into the TV HDMI interface;4. Connect the other end of the HDMI connector to the HDMI interface on your computer;5, start the computer and LCD TV, remote control of the LCD TV "signal source" adjusted to "HDMI" mode".(remote control)(TV set)6, after switching to the HDMI signal, the general TV will display the computer transmission screen.7, if the screen does not match the resolution, there is no picture, you can set the resolution of the screen on the computer to achieve the best display effect on the tv. Click the right mouse button on the computer pop-up menu, select the screen resolution into the settings interface;8, in the resolution settings interface, the monitor is set to tv;9, select the monitor for the TV, the computer will automatically detect and recommend the best resolution, the user can adjust the resolution according to the actual effect of the TV display, so as to achieve the best display effect.10, select the best resolution after the "OK" can be.11, at this point, the television and computer screen has been docked to complete, and then set the TV set as the default speaker of the computer, to achieve synchronization of picture and sound.12, in the computer task bar to find the trumpet shape of the volume icon, right-click on the volume control options";13, in the volume control options "play" settings, select the TV "FTV", and right-click, select "set as the default device"".14, click "OK", the TV can be used as a computer speaker.So far, computer picture and sound and television docking success, then you can play the video on the computer test results.
[HDMI connection also need to be connected to audio?:HDMI display comes with speakers and speakers;HDMI display signal line contains video and audio signals;HDMI card has audio signal jumper terminal, audio signal output must use the jumper receiving card; if the card [input image through the HDMI transmission to the TV, then the sound card is how to pass? Answer in the frontWhat's the difference between "HDMI" and "VGA"? HDM is HD, VGA is analog, audio is also different: VGA no...
