RGB to HDMI Converter – Top 4 Picks in 2023

RGB, or Red, Green, Blue is a traditional output for analog video signals, allowing you to send the images to another device where they can be displayed properly. An RGB cable will provide you with better signal quality than a standard RCA cable. However, it is only suitable for video, you’ll need a separate audio cable if you want to hear any sounds. 

HDMI is an abbreviation of High-Definition Multimedia Interface and has become the standard for transmitting uncompressed video data and compressed, or uncompressed, audio data. HDMI allows the transfer of digital signals and has become the new standard. That’s why you’ll find HDMI ports on the majority of electronic devices, including televisions, computers, and video projectors. 

In short, the HDMI cable offers higher quality images.

Why A Converter is Needed

It is possible to adapt an HDMI cable to allow it to carry RGB signals. However, this is not a viable solution as the HDMI cable plugs into an HDMI port. The port is expecting an HDMI signal and won’t know what to do with the RGB signal.

The converter simply receives the RGB signal and, using electronic chips, converts this into an HDMI signal. This signal is sent down the HDMI cable and into the receiving equipment, allowing you to play videos from home theater devices and older equipment with RGB outputs, on your modern television or projector. 

The Best RGB to HDMI Converters Currently Available

You won’t be surprised to find there is a variety of RGB to HDMI converters available. Of course, some are better quality than others, which is why we’ve created a list of the best ones. 

However, before you take a look, you should be aware of what to look out for when choosing an RGB to HDMI converter:

  • Manufacturer

Ideally, you should choose an RGB to HDMI converter from a recognized manufacturer. This will help to ensure you are getting a high-quality product. 

If you don’t recognize the manufacturer, speak to family and friends to see if they have heard of them and had any dealing s with them. If this doesn’t help then you’ll want to look on social media to see what other customers have said. You’ll find an array of honest opinions that can help you to make the right decision about any adapter.  

  • Components

All RGB to HDMI converters will have an HDMI output port and three ports where the RGB cable will plugin. They should also have a port that allows power to be delivered directly to the unit as most converters will require a separate power supply. It should also have audio input ports to allow the audio signal to be added to the HDMI output. 

Of course, this can be bypassed with an audio cable going directly between the two devices, but going through the converter is a much simpler and neater option.

The box itself is likely to be fairly small and it won’t usually come with the RGB and HDMI cables, you’ll either have these already or need to purchase some. 

  • Price

It is worth noting that these converters are not generally expensive. You should be able to purchase a good quality one for less than $50. In other words, if the price is high, look elsewhere.

Paying attention to the above will help to ensure you get a good quality RGB to HDMI converter. Of course, you can simply choose one of the following.
