  A few months ago, I was looking for a new TV, and I wanted to get something with the latest features.

  I didn’t want to regret not getting a fully packed TV with great functionality after a few months. 

  My aim was to invest in a device that came with support for the latest connectivity technology.

  After I started researching the TV that fit this description, I realized that there are different connectivity protocols for multimedia transfer. HDMI alone has several different connection protocols that serve different purposes. 

  It’s necessary to have ports that support the newest technologies in any device you buy, and that’s why understanding HDMI MHL and HDMI ARC are essential.

  Different abbreviations and technicalities can confuse many. Hence, in this article, I have explained what HDMI MHL and HDMI ARC are to clear up that confusion.  

  HDMI MHL port helps you connect your smartphone (and other devices) to your TV, while the HDMI ARC port helps in the two-way transfer of audio files between your TV and audio device.

  In this article, I have detailed different versions of HDMI MHL and ARC, their uses, and the devices that support the features in this article.

  What is HDMI MHL?

  
  

  MHL, introduced in 2010, is short for Mobile High Definition Link. As the name suggests, it is used to link your portable device via HDMI.

  You can connect your tablet or mobile to your HDTV or video projector’s HDMI MHL port via an adapter/cable. 

  In addition, it can be used to link your smartphone with your TV to project the phone’s screen to your Television with MHL.

  With MHL currently supporting up to 8K resolution, you can change the screen quality of videos on your TV through your smartphone. 

  You can also play high-quality audio from your mobile device to home theatre systems with MHL supporting Dolby Atmos and DTS:X. 

  MHL’s most helpful feature is for gamers, as you can play your mobile games on the big screen with minimum lag compared to wireless connections while even getting your phone charged simultaneously.

  You can use the mobile device as a game console or controller with MHL. 

  Another feature is that you don’t have to use your mobile phone to navigate and browse the content, even if it is connected. You can use the TV remote instead with MHL devices. 

  MHL is also used in vehicles. This tech allows smartphones or tablets to connect to your car’s compatible infotainment system through MHL.

  The system allows you to access your phone’s media library through the car’s infotainment system while charging your phone. 

  What is HDMI ARC?

  
  

  ARC, introduced in 2009, is short for Audio Return Channel. It is the most standard HDMI protocol.

  This HDMI protocol offers a two-way transfer of audio files between devices through a single connection. 

  The ARC protocol comes in handy when using an external audio system with your Television.

  Moreover, this technology helps you to use a single remote to control both the TV and the audio system.

  You can use the TV remote to power on and change the volume of the audio system.  

  The latest HDMI I 2.1 offers some interesting features, including eARC or enhanced Audio Return Channel. Regular ARC has Dolby Atmos support, while eARC offers DTS:X, Dolby TrueHD, and DTS-HD Master Audio streams, including Dolby Atmos. 

  eARC offers higher data transfer bandwidth and speeds up to 37 Mbps which is a huge improvement from the older 1 Mpbs.  

  Versions of HDMI MHL

  There are different versions of MHL released at different periods. These are MHL 1.0, MHL 2.0, MHL 3.0 and Super MHL.

  MHL to USB

  
  

  The MHL version 3 connection protocol has the MHL Alt (Alternate) Mode feature.

  This feature integrates the USB 3.1 framework using a USB Type-C connector. 

  This Alt Mode enables the transfer of up to 4K Ultra HD video resolution and multi-channel surround audio (including PCM, Dolby TrueHD, and DTS-HD Master Audio). 

  This feature enables devices to transmit uncompressed audio/video concurrently with USB data and power over the USB Type-C connector. 

  MHL-enabled USB ports can use the functions of both MHL and USB ports. 

  MHL Alt Mode also features RCP, which enables you to use the mobile devices through the TV’s remote control. 

  Cables with USB C connectors on one end and HDMI, DVI, or VGA connectors on the other end are available. 

  Your device’s USB 3.1 C-type port doesn’t mean it is MHL Alt Mode enabled. The device should also be equipped with the MHL Alt Mode. 

  What Devices Support MHL?

  Many smartphones, tablets, and other portable consumer electronics devices, high-definition televisions (HDTVs), audio receivers, and projectors support MHL. 

  You can check if your devices support MHL from MHL Tech’s official website. 

  No Apple devices have MHL support, but you could still mirror your iPhone/iPad screen using a Lightning Digital AV Adapter from Apple. It has up to 1080p HD video support. 

  Newer Android phones have USB C-Port and support the DisplayPort standard, which enables USB-C to HDMI screen, mirroring the device’s display to a TV.

  What is HDMI ARC Used For?

  HDMI ARC transfers audio files between devices through a single connection. It’s commonly used to connect an audio system to a TV. 

  You can connect your ARC-enabled TV to your ARC-enabled audio system through an HDMI cable to play the TV audio through the external sound system and even control the external sound system with your TV remote with ARC. 

  The newest ARC version, eARC, supports DTS:X, Dolby TrueHD, and DTS-HD Master Audio streams, including Dolby Atmos. 

  The technology also offers Lip-sync functionality which ensures that audio stays perfectly matched to video. 

  What Devices Support HDMI ARC?

  Most Home infotainment systems support ARC as it is the most standard HDMI protocol.

  You can check the HDMI port on your TV, soundbar, or receiver. If the HDMI port has ARC marked, you can confirm that it supports ARC. 

  For ARC to work, the sound system and the Television should support ARC. 

  Final Thoughts

  Wireless Screen mirroring with MiraCast and AirPlay, HDMI MHL is barely seen.

  With ports disappearing from devices, wireless technology is reaching newer heights, and MHL is a thing of the past. 

  But MHL offers zero latency and rules out any audio-video delay. This is still an issue for  Wireless screen mirroring. 

  HDMI ARC is also in danger of going irrelevant as audio systems and Televisions are promising to offer seamless wireless connectivity.

  Audiophiles and Gamers still prefer wired audio systems complaining about quality and latency issues. 

  Since you understand what MHL and ARC have got to offer, you might be able to make a choice concerning the tech you purchase.
