This cable seems to have little function beyond use in NEC video projectors.It's a male HD-15 VGA connector on one end with a 12" cable connecting to a male 5-wire RGBHV BNC connection on the other end.The latter seems to be only used in NEC projectors..

Many modern televisions have analog inputs as well as the digital HDMI input. It is worth checking the manual to see if the television supports RGB inputs with separate horizontal and vertical sync signals. If the television has an RGBHV input, the VGA signal may well work through it.

If the television only has HDMI inputs, the PC will need a DVI display output. This is a digital signal format that is compatible with HDMI. A DVI to HDMI lead should connect the two without problems. Note that HDMI also carries audio on the same cable but DVI does not. To connect the audio, a separate lead will be needed to connect to the analog input that is normally linked with at least one HDMI input. Once again, check the manual to see if one of the inputs has a selectable analog audio input.


DVI outputs can be obtained as expansion cards for desktop PCs and as USB devices for use with laptops.


Some newer PCs actually have HDMI connectors built in. Laptops sometimes have them fitted to save space on connectors. If this is the case, a single HDMI lead is likely to carry both video and audio signals.

There are a number of ways to connect a computer to a television. The best method depends on the connections available on the computer and the television and as these aren't mentioned in the question, here are two or three methods to try. Each assumes that the television is an HD model.

1

If the computer has a DVI output, connect a DVI to HDMI lead from the computer to to a spare HDMI input to the television. Also connect a 3.5mm jack connector to the audio output and to the audio connector that should be linked to the HDMI input. Using the television set up menu, specify that the audio for that HDMI input should be external to accept the signal from the 3.5mm connector rather than the HDMI cable.

If the computer has an HDMI output, a simple HDMI connecting cable should work without a problem.

3

If the computer has a VGA output, look for either a VGA connection of the television or a component input that has red, green and blue RCA (phono) connectors and two that are marked as "sync". An appropriate VGA to RCA lead should work in this instance but you will need to check the manual to ensure that the television can accept RGBHV signals.

Finally, if the television does not have a VGA input and the computer has nothing else other than a VGA input, consider buying a VGA to HDMI converter. It will cost from $30 upwards and are available from some electronics stores or from a number of on line suppliers.

There are several types of HD input to a television. The most common is HDMI, a compact connector that carries digital video, audio and control data in a single cable assembly. The other common input is a set of BNC or RCA jacks marked as RGB. Often the RGB jacks have additional jacks marked as sync or S or perhaps a pair marked as H and V. The RGB input is analog rather than digital. Note that there is a further input called component - this is commonly marked as Y, U, V and also uses three RCA jacks. Component is NOT RGB and the two are not interchangeable. Some inputs can be configured to be either RGB or component. Check the TV manual for this information. VGA is an analog signal with 5 separate lines, referred to as RED, GREEN, BLUE, HORIZONTAL and VERTICAL. This will normally connect to the RGBHV input of the television if there is one. It is important to note that the operating frequency of the signal may not be compatible with the television so it is worth checking with the user manuals before trying it. A cable with a 15 pin high density D connector at one end and 5 RCA jacks at the other will be needed and they can be obtained from most specialist computer or television dealers. Note also that HDMI is compatible with DVI which is the latest display standard for computers. DVI does not carry audio but the video image is identical in format to other HDMI video signals. Once again, it is worth checking the user manual for the television to ensure that the signal frequencies can be displayed.

You should be able to purchase an adapter at your local Radio Shack or equal. The problem you will run into is the pixels(amount of dots per inch)in a computer monitor are double that of a TV. Due to this fact, the text will appear fuzzy.OK for games though. Good luck.

get a device called a "scan converter"

if you have a video cards with video out it should be easy to hook up. check your card and manual.

my travel desktop has a geforce 2mx 400 it will do duel display in windows but wont display on boot unless i have no monitor connected to the vga it then detects no vga and switchs over to TV out. your exp my vary.

Look at your electronics store for a 'TV-out' card. This will probably be a PCI card which you will need to install inside in your computer. You can then hook up your TV's cable to the back of the card.
