Computer has vga port and tv has hdmi port

i use a 42" lcd as my computer monitor, just plug the computer to it with an hdmi cable to the hdmi1 port on the tv, and to the hdmi out port on the computer. if the computer doesnt have an hdmi out port, you can get the vga to hdmi adapter at radio shack or nest buy fairly cheaply.

Does your TV have a VGA port? If not it most likely has an HDMI port. Does your PC have an HDMI out on the video card? If not then you will need a VGA to HDMI adapter, OR a DVI-D to HDMI adapter, depending on if your GPU output is VGA or DVI-D. Then you will need an HDMI cable to go from the TV to the adapter.

did you change the input on your TV ?

An HDMI to component video cable will not work. These are meant for projectors that work with computers and have only component in jacks.

You will need is a VGA to Composite video converter, VGA to component video converter or HDMI to component video converter. These translate the computer output to the input the TV will understand. Here are some VGA to component video converters: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html . (The exception is if your computer has a TV-out port. In this case, you need an adapter that looks like an S-video plug that will then have composite or component video jacks.) If you want to use the TV speakers, you will also need a 3.5 mm to 2 RCA audio adapter (either M and F/F for an RCA cable to the TV or F to M/M for a 3.5 mm audio patch cable) or cable (3.5 mm M and M/M RCA).


I hope this helps.

(A computer gives RGB output on the VGA cable; the TV reads PbPrY on the component video. Thus you need for the converter rather than a simple adapter. Similar communication differences apply on the HDMI signal.)

Unfortunately. the HDMI port on the M190VA does not interpret the signal from a computer. The HDMI signal from a set-top box is different than that of a computer. You need to use the VGA port and the PC audio in on the TV; if your computer doesn't have a VGA port, use a DVI to VGA adapter or other appropriate adapter. You will need a 3.5 mm audio patch cable to use the TV's speakers. See page 25 of the M190VA manual here: http://store.vizio.com/documents/downloads/hdtv/M190VA/364User%20Manual.pdf .

I wish that I had better news for you.

Most TVs will have HDMI and RCA component and composite jacks. Some TVs will also have a VGA port. Your laptop will have a VGA port. (If the laptop is fairly new, it may also have an HDMI port.)

Not all TVs will support an HDMI signal from a computer, so the VGA signal is often better. However, that limits you to SD (anything with HDCP will fail.)

Very few TVs ship with the HDMI or component cables. However, there are some vendors who do package the HDMI cable with their TV. Without knowing which exact model of TV and laptop, I can only make a few suggestions. I know that the TCP42ST30 (Plasma 42") doesn't have a VGA port.

Look at your laptop for any external monitor port. VGA ports are generally blue female ports with 15 holes (D-Sub). If your TV has a matching VGA port, get a standard VGA monitor cable.

If you have the VGA port on the laptop but not on the TV, you can try a converting from VGA to HDMI. (You may need a DVI to VGA adapter and either a DVI to HDMI cable or a DVI to HDMI adapter.) Note: this gives an analog signal (RGB format) to the TV. You'll also need to make sure that your VGA port is active (in the BIOS for some computers) and then set your computer to send the signal to the external monitor. It is best to turn off both the computer and the TV before connecting the two. Then turn on the TV and set it to the correct input before turning on the computer. (In Windows 7, I set the video signal for the external monitor by right clicking on the desktop and selecting Graphics Properties. Set the signal to the external monitor and click Apply. Then click OK (in the external monitor's screen).)

If this doesn't work, you need a VGA to component video converter. (Not a VGA to component video cable - those are for projectors that read the RGB signal.) See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html .

Some laptops come with an HDMI, mini-HDMI or a DisplayPort option. For the latter two, you will need the appropriate cable with that end and the HDMI connector on the other. Then connect the TV and the computer as described above. (Note: my TVs accept a computer signal at the HDMI port labeled HDMI/DVI. However, you need to make sure that your TV understands this signal. It isn't the same format as that from a set-top box. My laptop has VGA and HDMI out; the desktops have VGA, DVI and HDMI (on one).)

If you add a comment with the model of your TV and laptop, I'll be glad to give you more specific options to connect the TV and the computer.

I hope this helps.

(A DVI port is a digital video out option with ~21 pins and is usually white.)

This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

I dont believe that laptop has an HDMI port on it. If you have an LCD TV then your TV may have a VGA or DVI input on it. You can connect your laptop to the TV by using a VGA to VGA or VGA to DVI cable. If you your TV doesn't have one of these input ports, then you're not going to get your laptop connected to your TV.

you mean your tv doesnt recieve signals from your computer try using a monitor and a tv first at the same time then go to the graphic video to change it from monitor to lcd tv.
