HDMI to DVI Adapter or Cable : Don’t Make Mistakes !

Have you ever tried to connect a High Definition Multimedia Interface (HDMI) source with a Digital Video Interface (DVI) source? For those who have given it a try, you probably discovered almost instantly that the two ports are incompatible with each other.

HDMI and DVIJust to refresh your memory, the main difference between HDMI and DVI is audio. HDMI has integrated audio signals while DVI only transmits digital video.

This article will give you step by step guidelines on how to convert signals between HDMI to DVI.

In addition, you will get to know some of the highly recommended cable models to guide you in picking out the most efficient ones as you go out shopping for these vital electronic accessories.

How to Convert Signals Between HDMI and DVI

It is important to understand that the digital video signals for HDMI and DVI are similar. Nevertheless, you need a HDMI to DVI adapter or cable in order to effectively transfer the digital data between the two ports.

Since there is no need to convert the digital video signal between HDMI and DVI, an adapter will not therefore act as a converter but as linkage. If you already have a HDMI or DVI cable that came with your HD television or computer tower, then all you need is an adapter.

HDMI to DVI adapters are the most efficient and cost effective way to make use of the cables you already have. However, it is highly recommended to carefully check before purchasing in order to ensure that you get the right adapter/cable for your devices.

Factors to Consider Before Choosing HDMI to DVI Adapters

Type of DVI Connectors: DVI connectors come as different types including DVI-D, DVI-I and DVI-A. The DVI-D connector has the ability to transmit digital signals while the DVI-A transmits analog signals.

On the other hand, the DVI-I connector is able to send both analog and digital signals. Furthermore, DVI-D and DVI-I connectors come as either single/dual link. Dual-link connectors have more pins compared to single link connectors.

As a result, dual-link connectors have the ability to transfer more data than single-link connectors. In addition, HDMI to DVI adapters can come with a male or female connector on either end. Ensure you get the correct configuration before flashing out your cash.

Type of Cable

If you already have a HDMI cable, get an adapter with a female HDMI connector and a male DVI connector. On the other hand, if you already have a DVI cable, get an adapter with a female DVI connector and of course a male HDMI connector.


Since the single-link connectors have fewer pins, they are compatible with more DVI ports than dual-link connectors. It is therefore recommendable to carefully check the DVI port on your device before purchasing a HDMI to DVI adapter to avoid incompatibility issues after giving out your cash.

Types of HDMI to DVI Adapters/Cables

There are many HDMI to DVI adapters; some that include an audio plug on the HDMI side that is converted into the DVI signal. However, the use of an adapter and a separate audio cable is the only cost-effective way to convert signals between HDMI and DVI. Some of the popular HDMI to DVI adapter/cable brands include

In addition, their convenient length helps to decrease strain on connectors hence preventing their damage. These HDMI to DVI adapters will undoubtedly enable you to set up your home entertainment system exactly the way you desire it to be.

HDMI to RCA Converters or Cable. What to buy

So, you have a great game system, laptop or even a DVD player and the only output from it is HDMI. However, the only inputs you have available are RCA – the round yellow, red and white plugs. The problem that you need to address is how to convert that HDMI signal  to composite video and audio.

hdmi to rca converterFirst, you need to realize that the video signal you’re going to display on the TV is not really going to be all that great. Remember that HDMI is designed for high resolution video – generally over 1920×1200 or even better.

The best resolution that the composite RCA yellow video “in” can handle is NTSC or PAL – which is about 525 lines — around 640×480. That being said, you’re still going to want to plug the XBox in and play Halo while you’re hanging out in grandma’s basement even if the resolution isn’t all that great, right? Right.

That means you’re going to need some kind of downscaling converter. The HDMI output is designed to be a bi-directional system. It’s expecting some kind of negotiation process between the game system or laptop and the display. However, that giant tube TV that you’re trying to use isn’t that smart. It’s just expecting the video and audio to come into the RCA connectors.

Don’t Get The Wrong Device!

Some converters are designed to take an old RCA device – like an old VCR – and allow them to be plugged into an HDMI input on a newer TV that doesn’t have RCA jacks. That’s probably not what you want. Make sure that the device that you’re buying converts from an HDMI output to an RCA TV input – not the other way around.

The second mistake is buying an inexpensive cables that go from HDMI to “component” video. Component video is a 5-RCA plug system with two for audio and three for video (RGB). That’s not what you want, either. You want HDMI to “composite” video – 1 yellow (video), 1 red and 1 white (audio left and right).

Here are some recommendations for HDMI to RCA converters that you can buy:

gefen hdmi converter— CVID BG-450 converter is a nice small converter with the option for either NTSC or PAL output.

— Etekcity offers a converter that also outputs NTSC or PAL

— The Gefen converter is a bit more professional and outputs in composite, s-video or over coax and has a locking HDMI cable input port
