Or if you are wondering what is MHL, I will explain that too.
HDMI Alt Mode and MHL refers to standards that allow mobile phones to be connected to a display such as TV, monitor or projector via HDMI.
MHL enabled refers to a device that is compatible with the Mobile High-Definition Link standard. This standard allows for the connection of mobile devices to HDTVs and other external displays.
HDMI alt mode is an alternate mode of the USB Type-C connector that allows HDMI signals to be transmitted over a single USB Type-C cable. This allows for the use of HDMI cables with devices that have a USB Type-C port, such as laptops, tablets and smartphones.
I have reviewed one of these cables and you can watch the full video from the link in description or the comment section. But, before you even think about buying this cable, it is best for you to check if your mobile phone or tablet supports HDMI Alt Mode or MHL standards.
Follow these easy steps to find out if your mobile device can transmit signals from USB Type-C connector to HDMI.
First, check if your phone has a USB Type-C port. If yes and your mobile device is a newer model, it possibly supports HDMI Alt mode.
If you are using an older model phone or mobile device, you can use a Type-C video checker app to find out if your phone is supported. Even if your phone is a newer model, it is good to use the app to verify if it supports phone to TV signal transmission.
On an Android phone, open the Google Play Store.
Search for ‘hdmi alt mode check’.
There are many checker apps in this list.
I am selecting ‘Checker for Type-C Video’.
Install the app and let it finish.
At the time of this video, it is a free app to use.
Once installed, start the Checker for Type-C Video app.
The screen shows the phone details here and a button to check Type-C video support.
Click on this button and the result is shown here.
This Huawei P30 Pro mobile phone supports USB Type-C to HDMI video, so I can use this cable to display the phone screen to a TV.
Now, you can try and test your phone to see if it supports Type-C to HDMI video transmission.
If your phone supports Type-C video and you would like to get this cable, I have provided the link in the video description and the comments section. You can click the link and read more about the cable before purchasing it.
Let’s try another phone, Oppo A74 5G.
I’ve installed the same app as the other phone.
Phone details are displayed here.
Click this button and the result says that this phone does not support USB Type-C video.
Let’s test these two phones by connecting them to a TV.
Use a USB Type-C to HDMI cable such as this.
Connect the HDMI connector side to the TV’s HDMI input.
Connect the USB Type-C connector to the phone port.
As you can see here, this Huawei P30 Pro phone is capable of displaying its screen to TV as per the app test result.
Now, if I try the other phone which failed the app test, it is not going to display the phone’s display on the TV.
If you want to check for MHL support on your phone, you can use an MHL checker app to find out if your phone is supported.
On an Android phone, open the Google Play Store.
Search for ‘mhl checker’.
There are many MHL checker app in this list which you can choose from.
I am selecting ‘MHL Checker (Check HDMI)’ as it seems to be quite a popular app.
Install the app and let it finish.
Once installed, start the MHL Checker app.
It is a very simple and straightforward interface.
There is a box to display the check result and the button to initiate the check.
Tap on the ‘CHECK’ button and wait for the result to be displayed.
As you can see here, this Huawei P30 Pro phone does not support MHL.
Although it does not support MHL, this phone supports USB Type-C to HDMI video transmission as we have tested using an app earlier.
The two Android apps called Checker for Type-C Video app and MHL Checker app allow you to test your phone if it supports video transmission via USB-C to HDMI.
Although I can’t provide HDMI Alt Mode for USB Type-C supported mobile list or MHL supported mobile list, you can use the apps to find out the results yourself using your own mobiles.
