HD TV with DVI-I (No HDMI)
I have a Philips TV with a stupid DVI-I socket. I am desperate to find an HDMI adapter for it but am not convinced that any out there are exactly what I need. Many say simply DVI or DVI-D NOT DVI-I. Can someone clear up what I need and where I can get one from? Cheers

It's rather confusing - but actually simpler than you think!. DVI has both analogue and digital, but HDMI is digital only - so any adaptor has to be for the digital side.
You might consider getting an HDMI/DVI lead instead of an adaptor?, it may be easier to source?. |

Well I thought it would be much cheaper to get an adapter. The only confusion is do I HAVE to get a DVI-I adapter or will a DVI adapter do the job? And likewise if I get a cable does it need to be DVI-I?

Get an HDMI cable, and put the adaptor at the DVI end, then you can't get it wrong. If you get a cable DVI/HDMI it has to be right, because HDMI is digital only.
It says its a DVI-I input in the manual and I also read on a forum somewhere that DVI-D would not work. Perhaps a DVI lead carries both DVI-I and DVI-D - who knows!! Actually I've just looked on Wikipedia it says "DVI-I (integrated, digital & analog)" So surely that means either will work! |

What you need is one of these.
http://www.tvcables.co.uk/cgi-bin/tv...I-Adapter.html I have been using the same thing for over a year with my Philips set. I have used an upscaling dvd player through hdmi, a sky HD box through hdmi and an xbox 360 through VGA all going through this connector into the TV and have had no problems. Hope it works the same for you. |

Hi All,
Sorry to jump in but I'm having the same issue with my Philips tv! (we've done the intros already over on the HDTV forum dannyb!!) Another forum member recommended the HDMI-DVI cable as below but I'm worried it's too cheap at £3.68! Do you think the quality will just as good as an expensive one?? http://www.cclonline.com/product-inf...ategory_id=182 Also does anyone have a link for the cable that I will need to carry the sound from my DVD player to the tv?? All the choice baffles me!! ![]() Thanks in advance. |

That looks exactly like the one I am using on my SKY+HD so will be fine for a DVD HDMI equipped player and since you are using a digital link there is no reason to pay a lot especially as the price of cable is sold off the back of very suspect claims of increased performance.
While that's true when you get to more extreme lengths a short digital cable need not be expensive. As for the audio cable then this is the sort of thing you want and again can be bought cheaper, sorry can't be 100% since I don't use that input on my Philips which has the same setup as yours. The twin phonos will take the analogue audio from the DVD and pass it into the 3.5mm input for the DVI socket, touchwood you are then good to go. |

There are three main kinds of DVI connections which are available; DVI-D, DVI-A, and DVI-I. DVI-D is the ‘true’ digital format. It is the normal format used for connecting digital LCD monitors to DVI graphics cards. DVI-A is the analog version of DVI; it is used to carry a signal from a DVI graphics card to an analog display, for example a CRT monitor. There is a digital to analog conversion applied here, but this still gives higher-quality results than a standard VGA cable. Finally, there’s DVI-I, the integrated format which caters for both digital and analog equipment. This doesn’t convert a pure DVI-D output to something a DVI-A device can use. But it will act as a DVI-D cable or a DVI-A cable according to your needs. The real benefit is that you don’t have to use two different cables if you use both digital and analog displays.
Having said that, you’re pretty unlikely to run into trouble if you stick with the cables that come with whatever new display you buy. Where you need to take care is when buying cables separately. Although you’re unlikely to need anything other than a DVI-D cable when dealing with LCD screens, it could still be wise to consider buying a DVI-I cable to cover both eventualities. However, do be aware that some manufacturers have been making the blade part of the pin set in DVI-I cables larger than normal; this could affect how it fits in some equipment. There is, unfortunately, still more to the DVI connection format. DVI-D and DVI-I can come in single-link and dual-link forms. Fortunately, again, this isn’t as complex as it sounds at first. The dual link varieties provide twice as much power and deliver the data more rapidly than the single link kind. This has a practical benefit with larger monitors, in that it allows a higher maximum resolution to be transmitted. In compatibility terms, the physical difference between single link and dual link is purely a matter of the absence or presence of extra pins in the middle section of the plug; any DVI-D or DVI-I-ready graphics card can accept either level. Telling them apart Recognising the different DVI formats isn’t hard once you know what to look for. All forms of DVI have a flat blade at one side of the plug, slightly separate from the main group or groups of smaller pins. With the pure digital DVI-D format this is on its own, whereas the formats which support analog data (DVI-A and DVI-I) have four pins grouped around this flat blade. DVI-D and DVI-I connectors have two equal groups of small pins (if they’re single link) or one solid group (if they’re dual link), while DVI-A has fewer pins, unevenly distributed between the two groups. |

Interesting idea?, why should DVI-A cable give better results than a VGA cable?, when it's exactly the same signal, and you can connect one to the other.
All DVI-I does is integrate (hence"I") the VGA analog signal with the DVI digital signal on ONE connnector using the extra pins on the Microcross connector configured for DVI-I. Most PC Graphics cards with DVI (-I) connectors still give out analog VGA signals, just via the analog section of the DVI-I connector. There is no analog-digital conversion going on in the DVI-VGA adaptor, just a straight pinout change from the analog section of the DVI-I connector into a 15 way"D" for the analog VGA signals. Niall, you are 75% right but a little confused on the detail. Read my previous post referenced above (and the links in it) that explains it all. LCDMAN..................Welcome to my world! |

I'm not so sure about that. In that case you're saying that DVI is also solely digital and yet you can get DVI to VGA adapters but VGA is not digital I don't think.
DVI-a is analogue (VGA), DVI-d is digital. DVI-I is a port that supports both. HDMI is digital only. Just buy a HDMI/DVI adapter. It will work. -Chris |

But DVI-A is very, very rarely found as DVI-I is backwards compatible with VGA.
