Clarifying MHL adapters for the S4 (tested on mine today)
Saturday 27th of April 2013
Thought I would start a thread to put this out there, since I know a number of people are confused or uncertain about which MHL adapters work with the S4.Firstly, the S4 uses an 11-pin MHL configuration, as the S3 and Note 2 did. Secondly, it is the first MHL 2.0 spec device. MHL 2.0 adapters do not require a charging input, however if you do have one connected they double the charging power going into the connected device (hopefully will finally solve the issue of power slowly dissipating when using MHL). They also increase output to 60Hz/60fps from 30hz on MHL 1.0 spec devices. Apparently 3D content can now be mirrored too.I have tested it a little today and can confirm the following:S3/Note 2 11-pin MHL adapters will work with the S4 also, older 5-pin adapters will not (you can get an adapter to allow them to work though).The Smart Dock also works with the S4.The S4 MHL 2.0 adapter does indeed work without a charging input.Hope this helps.
MHL is the future: provides HDMI-out and charges device at the same time
Tuesday 17th of May 2011
What is MHL other than a new acronym for the tech averse Android community to remember? Well, aside from being the lifeblood of HDMI-out on the HTC EVO 3D and Samsung Galaxy S II, MHL is the next stage of media output from mobile phones.MHL is shorthand for Mobile High-Definition Link, a connection standard that supports 1080p HD video and Digital Audio at 7.1 Surround Sound when linking a mobile device to a television. So when someone records video on an Android phone or wants to share select multimedia content on a TV, that person can connect their MHL-capable phone with a compliant television and enjoy a better media experience.HDMI-out already handles that on my phone, so big deal, right? Wrong. What sets MHL apart is the ability to provide power while connected to a television. Current HDMI-out links from a cell phone can lead to battery draining quickly, but MHL connection modes actually enable charging while sending audio and video from the phone to an HDTV set. Rather than deplete the battery, MHL gives it a boost. And best of all, you can sit back down on the couch once t
Samsung Galaxy S II first with MHL port for dual-purpose USB or HDMI out [Video]
Wednesday 23rd of February 2011
There's a small but important fact about Samsung's newest Android flagship that slipped under our radar last week at Mobile World Congress. The Galaxy S II is the first smartphone to feature an MHL port. MHL, as you'll recall, was first announced in 2008 as the Mobile High-Definition video Link "standard" for mobile devices promoted by a consortium that includes Nokia, Samsung, Toshiba, Sony, and Silicon Image. So yeah, another mobile interconnect standard just like DisplayPort, mini-HDMI, or Light Peak. Essentially, the micro-USB shaped MHL jack at the base of the Galaxy S II features internal circuitry that recognizes USB or MHL impedance and then automatically switches the phone into USB data / charging or MHL audio / video / charging modes. A special 5-wire micro-USB to HDMI cable lets you send video and audio to existing HDMI-equipped displays. Unfortunately, the TV won't charge the Galaxy S II during playback unless you insert a phone charger adapter between the GSII and TV or wait for MHL-enabled TVs to begin shipping later this year. Once connected, you can then us
HTC EVO 3D Will Have HDMI Port Compatibility Without an HDMI Port Thanks to MHL [Video]
Monday 28th of March 2011
The original HTC EVO 4G was dubbed the best smartphone on the market. Its HDMI port was one of many different factors that helped put it over the top, but its successor – the HTC EVO 3D – is missing one. Don’t worry, though, as HTC is one of many hardware partners teamed up with MHL to usher in a new standard of hard-wired connectivity between your smartphone and your television.MHL stands for Mobile High-Defintion Link and essentially turns your microUSB port into an HDMI port. Using one of MHL’s cable, you can simply plug the USB end into your phone and your HDMI end into the television without having to worry about signal degradation in the conversion and without needing to setup weird converter configurations.Not only does MHL send video and audio through the same cable to your HDTV, it also charges your phone in the process. There is currently no setup that can feed HD signal to an external source while charging the device using the same connection port. (You can set a phone inside of a multimedia desktop dock and have it charging while multimedia signals
HTC EVO 3D And View 4G Use A Single MHL Port That Allows For Both MicroUSB And HDMI Charging - Yes, Your TV Will Charge Your Devices
Saturday 23rd of March 2013
Something that surprised me at the CTIA conference yesterday was the connector port used in both the HTC EVO 3D and View 4G. Instead of 2 distinct standards, like on the EVO 4G - MicroUSB and MicroHDMI - the new EVO devices have only 1 port that uses the brand new MHL technology (Mobile High-Definition Link). And it is brilliant.The MHL 1.0 standard, finalized a few months ago, uses a single port to connect both HDMI and MicroUSB, and get this - it is able to charge via HDMI as well. Your MHL-enabled TV, connected to your mobile device via an MHL-HDMI cable, will be able to charge it much faster than MicroUSB.The MHL port itself is backwards compatible with any MicroUSB cable you plug into it and automatically detects whether it should transfer data or audio/video. Speaking of the latter, MHL natively supports 8-channel audio and full 1080P HD video. Not bad, eh?The first and only device that supported MHL until today's EVO announcement was the Samsung Galaxy S II, and TVs with built-in MHL support should be arriving sometime in Q2 2011. It's not exactly ideal, but don't rush out to
PSA: Samsung's Official Galaxy S4 MHL 2.0 Adapter Is Now Available In The US, Costs $40
Monday 24th of June 2013
This isn't exactly breaking news, but some time in the last week or so Samsung began shipping the Galaxy S4's official MHL adapter through its site and various retail partners in the US. The new adapter has been on sale for over 2 months abroad, but is just now finding its way to American shores.MHL adapters, if you aren't aware, allow you to transmit HD A/V signal from your phone via a microUSB to HDMI piece to a television or monitor. The Galaxy S4 is one of the very first smartphones to user version 2.0 of the MHL standard, which no longer requires an external power source in order to be used (just don't be surprised when it demolishes your battery). There is still a charging port on the adapter, however.Why exactly is this noteworthy? Well, while the Galaxy S4 will work with most 11-pin previous-generation MHL cables, there have been complaints that it can be a bit picky about which it wants to play nicely with. MHL 2.0 also brings 60Hz video playback, which means it will look much nicer on your TV than the old MHL adapters do. The new MHL 2.0 adapter is also backwards-compatibl
MHL 3.0 spec unveiled with 4K support
Tuesday 20th of August 2013
MHL, the standard for sending high-definition video from portable devices, has today announced its version 3.0 specification. The highlights in MHL 3.0 include4K video support (up to 2160p30) and the ability to use input devices and other peripherals — mice, keyboards, touchscreens, etc. —thanks to a higher-speed two-way link.Also listed in the new spec are charging at 10W, 7.1 Dolby surround sound,HDCP 2.2 content protection and backwards compatibility with the MHL 1 and 2 standards. The standard will be "connector agnostic," according to the MHL group, with the ability to operate over as few as five pins.The full MHL 3.0 specification will be available to download in early September. There's no indication as to when we might see the first smartphones and tablets with support for the new MHL standard, but as the spec has just been finalized, it's unlikely we'll see anything in the immediate future.MHL CONSORTIUM ANNOUNCES NEW SPECIFICATION WITH MAJOR ADVANCEMENTS FOR MOBILE AND CONSUMER ELECTRONICS CONNECTIVITYMHL 3.0 Innovations Include 4K (Ultra
MHL 3.0 specification released, supports 4K Ultra HD resolution
Tuesday 20th of August 2013
The MHL Consortium announced today a new specification, MHL 3.0, that establishes new standards for connecting mobile devices to displays, including support for 4K Ultra HD video. Ultra HD resolution is the newest resolution working its way down into the market now that some television manufacturers are producing units for consumers. In their announcement, MHL indicates a variety of content deliverers are working on plans to provide UHDTV content, including Comcast, NHK, the BBC, Netflix and Orange.Along with the support for UHD formats of up to 2160p30, the new MHL 3.0 spec covers simultaneous high-speed data transfer, improved remote control protocol support, power charging at up to 10W, HDCP 2.2 content protection, and 7.1 surround sound. MHL also indicates the specification is connector agnostic and can be run over as few as five pins.At this time there are still no smartphones or tablets that support the new MHL 3.0 standard. Keep in mind though that Android recently added support for a new DPI category, XXXHDPI, which would be suitable for 4K UHD TV. While many saw that as more
MHL 2.0? Is it working for you?
Saturday 09th of November 2013
So, I got the official Samsung MHL 2.0 adapter from their website, just to be sure I wouldn't get some cheap clone or knock-off. (There are coupons out there for Samsung customers to get it half off, if anyone is curious.) I got it and used it with my Verizon GN3, and it seemed to be working. I wasn't sure if it was charging or not (without a charging cable), but that can depend on the TV itself. However, a few hours later, I realized that the charging port on my GN3 was now broken. I literally had to take it to Verizon and have it exchanged for a new GN3 the very next day. Has anyone else had this experience? Has anyone else been using the MHL 2.0 adapter without issue? I'm getting a replacement MHL 2.0 adapter, but I'm still freaked out by this. I'm trying to see if others experienced anything like this, or if their MHL 2.0 experience with the GN3 has been problem-free. Any thoughts?

I know that it uses more power because of pushing it to the tv and powering the phone. But I'm using the official charger that came with my s4 and the battery goes quickly. It's running the screen, brightness is all the way down to 0 and whatever I'm doing and I want to know is there a way to either get the screen darker without darkening the mirror(screen filter darkens the mirrored) or just shut off the backlight completely? Or is there a charger that will charge and do the mhl power also?
