Using a tv as a dual monitor that plays audio from computer

You need a VGA cord you can buy it at Best Buy

Hi,

DVI connections only transfers video (it's not like HDMI). You can continue using your current soundcard to output to the LCD monitor.

The video cable should be a VGA cable, assuming your computer has a VGA connector. Get one that has M/M ends. This is sometimes listed as a 15 pin D-sub connection. Then connect a 3.5 mm audio patch cord (m/m) between the audio out (speaker/headphone) pf the computer to the TV's VGA audio in (if you want to use the TV speakers).

If your computer has an HDMI or DVI output, I do not believe that you can connect to the TVs HDMI port. (The signal from the computer is not the same as that from a set top box.) If you have a DVI port, get a DVI to VGA adapter and then connect to the VGA cable. (You could use a DVI-DVI cable and then the DVI to VGA adapter at the TV. However, space is an issue at the TV.)

Make sure that the VGA port is enabled on the computer. (Some newer computers have a different video port enabled initially.) This may require entering your BIOS just after turning on the computer. Usually you need to strike Esc, F1 or F2 repeatedly starting when you press the power button. (F10 is also a BIOS access with some manufacturers - the key will be listed in a splash screen that is only visible for a few seconds.)

With the computer and the TV off, connect the cables. Then turn on the TV and set the input to VGA. Next turn on the computer. (If this is the only monitor attached, the computer should find the correct resolution (Windows). If you are using a dual monitor option, then you may have to enable the TV as a monitor. This will depend on the OS. For my Windows 7 laptop, it's right click on the desktop and choose Graphics Properties. Set the monitor options for both, external or attached and click Apply. Then click OK when a confirmation window appears. With my Windows 7 desktop, it's right click on the desktop and choose Screen Resolution. Similarly choose the settings, click Apply then OK to confirm.)

I hope this helps.

The computer has VGA, DVI-I (dual link) and HDMI ports. The monitor has VGA, DVI and HDMI but only came with a VGA cable. Some computers have recently come with shielding covering all of the ports except the one that is currently live. Thus, check your hardware; the computers I've seen with only one active port, the HDMI port was active before resetting the video options. So get an HDMI cable (it will provide the best signal in addition). If the DVI-I port is currently live, you should get that cable as well and then change the settings to enable the HDMI port.

I hope this helps.

(you do not need to get the super-expensive cables; the low end ones will be fine. However a single link DVI cable is not the same as a dual link cable; sometimes using the wrong cable leads to no signal to the monitor.)

What problem are you having? The connection should be fairly straight forward depending on your computer's video out. You can use a VGA cable, DVI to HDMI (check your graphics card manual for single link or dual link on the DVI side), or component video (even S-video). If you have HDMI out on the video card, use an HDMI cable. If you want to connect to the TV's speakers, you need at least an 3.5 mm audio cable (or 3.5 mm to RCA audio).

The DVI cable can be either a DVI to HDMI cable or DVI to DVI or HDMI to HDMI with a DVI to HDMI adapter at one or the other end.

I hope this helps.

(you will need to go through the input modes to find the signal. Some TVs need to be on (with no signal) before the computer is turned on.)

No. HDMI transfers picture and sound, but DVI does not. You need a audio line as well.

Only if you've got an HDMI output on your computer. Some computers with higher quality video cards, or just newer ones will have a DVI output for a monitor. You can get a DVI to HDMI cable that will then be able to connect the two.

As others have said, if you have a video card with DVI output, you can get the video to the TV using a DVI to HDMI cable.

But no one mentioned anything about audio. DVI can not carry audio, so you'll need to send audio from the computer to the TV (or receiver). Some TVs have audio inputs associated to one (or more) HDMI ports for use with devices that have DVI, but not HDMI. My Sharp LCD has two HDMI ports, one with separate audio inputs, one without.

Im no expert on the subject, but I use my L37 for a monitor, and use just the vga adapter. It works good as a monitor, and both dvds and my hdtv wonder tuner card look great through the vga connection. They do make adapters for dvi to hdmi. Although, hdmi also carries sound, but you wont get that out of your dvi output from your card. So you might not have sound when using that connection, as your tv may not look to the headphone type jack used for sound imput from your computer when you select the hdmi source on it. If you have speakers already connected to your computer you may not care. Also if you have a 720 p Vizio, 1366x768 is the highest resolution you are going to get out of it anyway, if I'm not mistaken. I'm Not sure why you would need 2 connectios to the same monitor either. I posted 1 link below because they had several dvi to hdmi adapters. Hope that helps.

Laptop Multimedia Ports Info


Component Video Out: Connects a TV or HDTV to your notebook so you can view high-quality, high-definition video streaming from the notebook. This three-piece connection (color-coded red, blue, and green) is the best method for sending video from your notebook to an HDTV or anything that receives component video. This connection allows the chrominance (color) and luminance (brightness) portions of a video signal to be processed separately, thus producing higher-quality video than an S-Video connection. S-Video works similarly, but component video improves color accuracy even further by splitting the chrominance signal into two portions.
Composite In/RCA: Connects a gaming console or camcorder to your notebook, for viewing video or playing games on the notebook. Color-coded red, white, and yellow, composite video input uses standard RCA-style jacks to connect your notebook to receive video and audio signals from your TV, VCR, game consoles etc.


TV Tuner/75-Ohm Coaxial: Connects a cable box, TV, or VCR to your notebook, so you can watch and record TV content on the notebook. Sometimes called an Rf input, a 75-Ohm coaxial cable can carry video and stereo signals simultaneously. RF cable connectors (often called F-type connectors) screw onto the 75-ohm jack, are pushed onto it, or connect via a dongle that vendors usually supply.

S/Pdif/Dolby Ac3 Digital Out: Connects your notebook to speakers or a stereo receiver to play digital audio stored on the notebook. S/PDIF (Sony/Philips Digital Interface) is a standard audio-transfer file format, usually referred to as digital audio. This connection allows the transfer of audio without converting the signal to and from an analog format, which can degrade its quality. If you also have an S/PDIF In port, you can play digital music stored on an MP3 player through your notebook. The headphone jacks found on some notebooks double as S/PDIF Ports.

DVI: Connects a digital projector or LCD panel to your notebook to display in large format either video content or a PowerPoint presentation stored on the notebook. DVI (Digital Visual Interface) is a multipin connection used for passing standard-definition and high-definition digital video signals. It's found on HDTV tuners, a growing number of DVD players, HDTV-ready televisions, and some computer displays. DVI-D is the type of DVI connection found on most home video gear and carries digital-only signals. DVI-I is used with some computer video cards and can pass both digital and analog video signals. Some TVs have DVI-I inputs for greater hookup flexibility. DVI connections transfer video signals in pure digital form, which is especially beneficial if you're using a fixed-pixel display like a plasma, LCD, or DLP TV.


Firewire/ I.Link 400/ 1394: Connects a digital camcorder or external hard drive to transfer (but not display) large files, such as MPEG video, to your notebook. Also known as IEEE 1394, this is an extremely fast (commonly up to 400 megabits per second), two-way digital connection used for plugging in Your DV camera or other peripherals (such as an external hard drive or optical drive) to your notebook. It is used in digital camcorders because it is one of the few connections capable of quickly transferring full-motion video.

S-Video In: Connects a digital camcorder to your notebook to display video stored on the camera on your notebook's screen. Also, if your VCR has an S-Video Out port, you can transfer your VHS tapes to digital format. S-Video inputs use a four-pin jack to receive video signals from camcorders, gaming consoles, TV, or any device that has an S-Video out port. the S in S-Video stands for separate: S-Video connections transmit the chrominance (color) and luminance (brightness) portions of a video signal along different paths, allowing them to be processed separately, though S-Video does not produce as vivid an image as component video. This is a common way to display content from a digital camcorder or any device that has an S-Video Out port. (Firewire also transfers data files from your camcorder to your notebook, but it can't display video in real time on your notebook.)
S-Video Out: Connects a plasma or newer TV to your notebook to display video content streaming from the notebook. The most common way to connect a TV to a notebook, S-Video Out uses a four-pin jack to send signals from your notebook to your TV or anything that accepts S-Video In.
