HDTV or DTV
The TV will be an HDTV or identified somewhere as Digital TV (DTV). Usually they will put the word "Digital" somewhere on the front. Also the set may have some digital only connectors in the back.
When the US system goes all digital in Feb 2009 you don't really have to worry about it much cause there will be DTV boxes (like a cable box) that can get the digital signal and turn it to the same old analog your old set understands. Signal will be perfect though.

How can i use dvi port


DVI stands for (D)igital (V)ideo (I)nterface.

DVI is a new form of video interface technology made to maximize the quality of flat panel LCD monitors and high-end video graphics cards. It is a replacement for the P&D Plug & Display standard.

you can connect high definition monitor , LCD projector , LCD T.V to a DVI port

There three kind of DVI connector
1. DVI-D (Digital)
2. DVI-A (Analog)
3. DVI-I (Integrated Digital/Analog)

DVI-D format is used for direct digital connections between source video (namely, video cards) and digital LCD (or rare CRD) monitors

DVI-A - High-Res Analog
DVI-A format is used to carry a DVI signal to an analog display, such as a CRD monitor or and HDTV

DVI-I - The Best of Both Worlds
DVI-I format is an integrated cable which is capable of transmitting either a digital-to-digital signal or an analog-to-analog signal, but it will not work transmitting a digital-to-analog or analog-to-digital signal.


How to Recognize These three types of DVI Cable
There are two variables in every DVI connector cable, and each represents one characteristic.

The flat pin on one side denotes whether the cable is digital or analog:
A flat pin with four surrounding pins is either DVI-I or DVI-A
A flat pin alone denotes DVI-D

The pinsets vary depending on whether or not the cable is single- or dual-link:
A solid 27-pin set (rows of 8) for a dual- link cable
Two separated 9-pin sets (rows of 6) for a single-link cable

I live in Florida. I purchased a (Portable Mobility DVD) 16" Portable Multimedia DVD and LCD TV from a vendor in China. The TV unit only receives "Analog signals", which are no longer...


Hi there,

The gadget you need is called a Digital (to Analog) Converter.

This is also referred to as a digital Set-Top Box (STB) and connects to the cable from your antenna. The STB is then connected to the TV. An antenna only receives the signal and cannot convert the digital transmission to an analog signal which your TV can display. Please click on the link below for an example of a Digital Converter:

http://www.amazon.com/iView-1000STB-Digital-Analog-Converter/dp/B003P5MFX2/ref=sr_1_1?ie=UTF8&qid=1298837630&sr=8-1

I am uncertain whether this specific product would actually be suitable for you as you didn't fully explain what you mean by "mobile". This product would only be suitable for an RV if you have a DC/AC inverter and 120v transformer as it requires domestic mains voltage to work.

Please could you explain your "mobile" situation in a little more detail and let me know whether you have mains AC voltage. I will then be able to tell you whether this product is suitable for your requirements or find some alternatives that will be.

Hope this helps. If you need further assistance, please reply to me by clicking on "Add a Comment" below your question.

BElectric

We are in Ghana we need frequency and we update to get more channel


Your flat panel TV is probably factory set to receive ATSC signals (Hi-def DIGITAL TV), whereas
Ghana may not have converted from analog TV (NTSC) yet.

Digital TV's cannot receive analog signals. I'm just guessing about whether or not Ghana supports
Hi-Def broadcasts - you'll have to check with (any) TV channel in Ghana. The Analog-to-digital
conversion is an expensive one at the broadcast end, and may not have happened yet in Ghana.

The US conversion took place by FCC mandate June 12, 2009.
There are available $65 (USD) digital-to-analog converters, but what you may need is an
analog-to-digital converter, which doesn't exist. Your Flat-panel TV amy have to wait until Ghana
begins broadcasting a Hi-Def TV channel.

For a HD antenna, a regular old rabbit ear-type antenna will do.

How can I set my TV as analog or digital?


It should be done in the settings on the TV itself through the menu options and through the connections on the back. Whatever input you hook up as your source input on the back, the menu set up through the TV menu should correspond to whatever method you chose as your source, whether it be analog or digital. I hope this helps.

I have a Bush 6690D and I can confirm that it does have a built-in digital decoder for terrestrial signals (Freeview).

Have you checked whether ***********'s TV is set to digital mode ? The "Mode" button on the remote cycles between analog, digital and AV inputs.

Sony Trinirton TV and DAV-HDX 275 System


Here are a couple of the most common reasons for your problem:

Make sure you have selected the right input source on the DAV-HDX275 that your TV station source (cable, satellite, direct TV or whatever you get TV stations from) is connected to on the DAV-HDX275.

Also make sure that if you are using a digital input (HDMI, optical, or coaxial) from the TV station source, that the DAV-HDX275 in set for a digital input and on the right source.

If you are using an analog source (red and white RCA jacks) for the TV stations , make sure you do not have the digital input activated for that source on the DAV-HD275. You need to select the analog option.

You must also be sure that you have a cable, whether it is analog or digital, connected from the cable box to the DAV-HD275.

I hope this was helpful to you, it is always very important to double check all the connections and make sure the stereo is set to the right type of input (digital or analog).

If you have found this to be helpful, a good rating is always appreciated. Thanks and let me know if you need any more help.
