MHL (Mobile High-Definition Link) is a standard that lets smartphones and tablets send video, audio, and power over a single Micro-USB or USB-C cable to a TV or display — but it is rarely used today, largely replaced by wireless screen mirroring and USB-C video output.
- Both your phone and TV support MHL
- You use a certified MHL cable or adapter
- Your TV’s HDMI port is MHL-enabled
- Your phone doesn’t have MHL support (most modern phones don’t)
- Your TV’s HDMI port is not MHL-compatible
- You use a generic Micro-USB or USB-C cable instead of an MHL-certified one
What MHL Does
MHL carries up to 1080p video, 7.1-channel surround sound at 192kHz audio, control signals, and charging power — all over one cable. It uses your phone’s existing Micro-USB or USB-C port, so no dedicated video output is needed on the device. The TV’s MHL-enabled HDMI port also charges your phone during playback, which made it appealing for gaming and long video sessions.
TV remote control of the connected phone is another built-in feature, routed through the HDMI CEC protocol. This made MHL more polished than basic screen mirroring for couch use.
MHL vs. Current Alternatives
| Setup | Works? | Need | Note |
|---|---|---|---|
| MHL phone + MHL TV | Yes | MHL cable | Full video, audio, charging |
| MHL phone + standard TV | Yes | MHL-to-HDMI adapter | Verify adapter is certified |
| Modern phone + TV | No | — | Most phones dropped MHL after 2017 |
| USB-C phone + TV | Maybe | USB-C to HDMI cable | Depends on Alt Mode support |
Is MHL Still Used?
MHL peaked around 2013–2016 when wired phone-to-TV connections were common. After that, two things killed it: wireless screen mirroring became mainstream, and USB-C with DisplayPort Alt Mode offered a cleaner wired path on newer phones. The MHL Consortium stopped releasing new specifications, and major phone makers quietly dropped MHL support from flagship devices.
Today, very few phones or TVs advertise MHL support. If you have an older device from 2014–2016, it may still work. Otherwise, a wired connection is better handled through USB-C to HDMI on modern hardware.
How to Check If Your Devices Support MHL
- Check your phone’s spec sheet for “MHL support” — it’s usually listed under connectivity
- Look for an MHL logo next to HDMI ports on your TV
- Not all HDMI ports on the same TV are MHL-enabled — check which port number is listed in the manual
- If your phone uses USB-C, check whether it supports USB-C video output instead — that’s the modern equivalent
Bottom line: MHL was a well-engineered standard that delivered reliable wired phone-to-TV output with charging, but device support dried up after 2017. If you have older compatible hardware it still works fine, but for any modern phone your best wired option is USB-C to HDMI, and your best wireless option is Chromecast or AirPlay.
