Extended my monitor to a Vizio 37" LCD TV Echoed Sound
I have my PC connected to a Vizio LCD using a standard VGA to RGB connection. The sound is awful and sounds echoed using a standard audio speaker cable from the tv to the speaker (green color coded) jack on the back of the PC.
There is also a HDMI connection on the video card, will this work and will it transfer sound for the tv and the computer.
Keep in mind the LCD is only an extension of the PC monitor and is not used for TV purposes.

Re: Extended my monitor to a Vizio 37" LCD TV Echoed...
You have an HDMI connection on a Thinkpad T20??? Per definition, HDMI is supposed to send video and audio data from the TV to the PC -so, yes, it should work.
I say "should", because I tried to hook up my PC that way and I went back to a VGA connection (and sent the sound to an old stereo), because the resolution was awful. I rather think that the audio cable is the culprit here - if the connectors are not fitting perfectly, they can create a lot of distortion.
Also check your audio settings on the PC (updated driver, settings not on maximum volume, etc.)
If you want to try HDMI, there is no need to get the ultra expensive "Monster" cable. Look here for an example.

Yes of course.
First of all you will need to identify the available input ports on your TV. An RCA port is generally standard nowadays and it consists of a red, a white and yellow coloured reception ports (the colours may differ between tvs, i.e black instead of red). The red and white are for stero sound and the yellow is for video.
Modern TV systems also have a VGA adapter which is small flat port like the ones on a computer screen. This is usually blue.
A third option is an S-Video port, which is round in shape.
To connect your laptop using the RCA port, you will need an S-Video to RCA converter. You connect the S-Video to the port on your latptop, and through the converter to the RCA yellow port on your TV. For sound you will use another cable that connects to the headphone jack on your laptop and then splits to a white and a red cable to connect to your TV.
If you have VGA port on your TV, then connect the VGA port on your laptop to the VGA port on your TV. No converters needed. For sound you will use the same approach as above.
To use the third option you will need to have an s-video out port on your laptop and you will connect it directly to your TV s-video port. For sound, again you will use the approach as the rca solution.
Then, using your remote control, select the AV mode or depending on your TV select the PC or VGA mode.
Finally, to transfer the video from your laptop to your TV press and hold the Fn key on your laptop's keyboard and then the F7 or F9 key. (It has s small TV icon on it).
Your laptop will have a VGA output or possibly a S-video out. For the
VGA you'll need a standard VGA cable. Plug the cable in to your laptop
and the PC input of your TV. If your TV does not have PC input it may
have a DVI input. IF it does you can use a VGA/DVI adapter to plug it
in. If it doesn't have a DVI input you can use the S-Video output on
your laptop with a standard S-video cable. After the connection to your
TV is made you will have to toggle alternate display by pressing and
holding your [Fn] key and pressing F4, or F5, or another F# key. It's
the one that looks like a TV screen. Press once to turn on output,
press again to turn off your laptop screen, press again to go back to
laptop screen only
From user manual (page 68): Your computer comes with a built-in display panel, but you can also connect an external display device to an available video port, as follows: ❖ An external monitor or projector via the RGB (monitor) port ❖ A TV, VCR, or DVD recorder via the S-video (TV-out) port Before connecting an external monitor or video projector, configure your computer for the type of device you are connecting. To do this, refer to the documentation for your operating system and devices
So you have to use an RGB cable or a S-video cable : your cable should be plugged into 15 pin VGA port in your PC and plug it into a correspondent port in your TV. Try also S- video and select correponding input in your TV set (Both connection type DO NOT carry sound: use your audio connector from PC to TV audio input.) Configure your extended screen using your manual instruction: Once you have connected an external display device, you can choose to use the internal display only, the external device only, or both simultaneously. The quickest way to change the display output settings is to use the display hot key (Fn + F5): 1 Press Fn and F5 simultaneously. 2 While holding down Fn, press F5 repeatedly until the setting you want takes effect. Briefly pause each time you press the F5 key to allow time for the display to change. This hot key cycles through the settings in the following order: ❖ Built-in display only ❖ Built-in display and external monitor simultaneously ❖ External monitor only ❖ Built-in display and TV ❖ TV only
VGA cable doesn't carry any audio: use your audio output from PC into TV audio Input (standard RCA). You need to configure your Display Properties to manage TV screen to get an effective connection. Either you have a generic Video Grafic Driver add on (I'm using Intel Graphic accelerator) on your display properties either you are using a specific (NVIDIA) driver for your video card. To check go to CP/ Display, settings Tab and in advanced you should be able to check your choice (if you don't want to go to user manual. You can also (in CP/ Display, Settings tab configure TV as a monitor and select your option accordingly: use screen resolution on screen # 2 not over native resolution of your VIZIO screen (1080 x 960?) and be sure to use all the parameters as TV can accept. As soon as TV is configured as per resolution and refresh etc.. check the presentation function on your PC: it's normally a FN key showing a screen icon on key top (on my Acer travelmate is FN + F5) on aspire may be it's FN + F4. This function key will circle between: PC mail screen -> External screen (as you configured on Display settings) -> both screen.
If it is, then yeah you should be able to output VGA from a PC to the TV with a proper cable.
However if the TV has DVI or HDMI connections on it, it's better for
you to connect it that way. DVI/HDMI is a digital signal and if it's a
digital-based display tech TV, then you're better off using that. Also
if the TV does resolution above 1360x768 (i.e. if it does 1080p) you
can get higher resolution by going via DVI/HDMI...
The X1400 supports Full-HD resolution. Full-HD/True-hd (1920x1080)
The best output would be via DVI but you are limited with the VGA port.
I would purchase a Grand Hi-Wire PC to HDTV converter from www.globalcomputer.com. Item # G126-1036 @ $139.99
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it. Thanks, Joe
Every laptop has at least a VGA (computer video connection) and s-video cable port. A VGA cable is preferred if you want to be able to read text on your LCD TV. Check to make sure that your LCD TV has a VGA connector. It's a port that accepts a 15-pin connection so it's pretty easy to spot if it's there. It's just like a computer monitor cable if that helps. Should be able to find it at any local retail store that carries computers. VGA or RGB cable.
