How to attach...I have a Hitachi 65S500 65" and I want to use it as a monitor for my laptop (HP), what cables do I need ( I have a TV VGA to RGB Component cable, 3 FT Black) and where do I hook it up?

The projector has a RGB input
So to use it on a VGA output from the computer you would need a VGA to RGB adapter
or something like this adapter

with a component cable
as projector has component inputs also

Instructions

1. • 1 Decide if you want to watch the television on your computer or use the TV as a larger monitor. If you want to view the contents of the TV on your laptop, you need a video card connected to to the computer. These cards can either be inserted through the express PCI card slot on the laptop, or via USB cable. Make sure the video tuner card supports component video.
     
   • 2 Connect the DVI-to-component cable into the DVI port if you want to use the TV as a large monitor for your laptop. However, if you have a VGA port, plug the VGA-to-component cable into the VGA port.
     
   • 3 Plug the RGB component cables into the component side of the DVI- or VGA-to-component cable. If you want to watch the TV on your computer, insert the RGB cables into the TV video card.
     
   • 4 Plug the other end of the RGB component cables into the TV. If you are using the TV as a monitor, plug the cables into the "Component In" ports. However, if you are sending the TV signal to the computer, plug the cables into the "Component Out" port (the other end of the DVI- or VGA-to-component cable that you connected to your computer in Step 2).
     
   • 5 Power on the TV. If you are using the TV as a computer monitor, press the "Video" button until "Component Video" appears on the screen. If you are watching TV on your computer, launch the television viewing software that came with the TV tuner card. You can now see the contents of the TV on your computer.
     

The laptop looks like it has an external VGA port only and without knowing what model of Hitachi tv it is. It is quite possible the tv may have a VGA input in which case a standard VGA cable will allow you to connect the laptop to the tv. Otherwise you will need one of the following depending on what connections the tv has:

1. VGA to HDMI cable: http://www.amazon.com/Video-Cable-Black-Support-Necessary/dp/B002TUC64W/ref=sr_1_1?s=electronics&ie=UTF8&qid=1355697785&sr=1-1&keywords=vga+to+hdmi+cable

2. VGA to RGB cable: http://www.amazon.com/eForCity-Premium-Component-Cable-Black/dp/B0012SPNII/ref=sr_1_1?s=electronics&ie=UTF8&qid=1355697879&sr=1-1&keywords=vga+to+rgb+cable

If you do not have an HDMI input, you will also need to get an audio cable as well. Standard mini-stereo audio cables should allow you to connect the laptop to the tv.

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.)

In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

It will not work. This cable is meant for connecting a device with RGB outputs (Blu-ray, DVD players, etc...) to a display with VGA input (such as computer monitors).

you need to have the same connections on both my laptop has svideo or vga connector, some have Hdmi which is the newest, but the tv and laptop have to bot have the same connectors, it may be a dvi, or any that I mentioned, then you need a cable for your video, and another for your audio, both the audio and video cables are run to the tv, the only one that has both audio and video is the HDMI which tv's from the last hear or 2 usually do have. Then depending which input the laptop is using which it will tell you where the connection for the tv is, you set it to that input and that turns your tv into a giant monitor

I don't think and RGB cable will work with a VGA cable because the signal in the video card is completely different. It's not just the picture but the scaning and refresh rates are totally different. Even if you could wire one it probably won't produce a picture.

Hi there

You cannot hook up a PC & Projector with just a USB cable , you have to use a VGA cable for signal ( picture )

The USB cable is just to use the scroll up or down function from the standard remote controll when doing a presentation.
