    Default Should an MHL adapter just work?

    I just got an MHL adapter and hook it up according to instructions but no picture on the big screen. Is there some other settings I should be changing? Another thing is that it's not an actual Samsung product even though this ad said it was that way could that be in issue? Thanks all

    That could be a big issue. The S3 had issues with MHL adapters that weren't made for that phone specifically. The Note 2 could be the same way.

    Edit: Yeah looks like that's the case. I found this: which should work stand alone

    and

    This one that should fix the issue you're having: ..... Should

    I bought the Samsung MHL adapter. A power cord needs to be connected to it. As far as I recall, it just worked for me without having to mess with any settings on the phone. I started a video on my phone, and it played on the TV.

    Here's the one I got. Interesting that the photo shows it having a samsung logo on the item, yet the one I received DIDN'T have the logo! Hmmm...

    But the Title said specifically for the n7100.




    Thanks all...

    Is there a way to tell whether mine is 5 or 11 pin? I have a loupe that helps me see tiny stuff. But would that work, or is it something internal that I COULDN'T see?

    Thanks...

    FIGURED IT OUT!!

    Ultimately, it wasn't a bad adapter - it was that my case was keeping the connector from going in all the way! Now it works great!

    I suggest that people using MHL use an app called Screen Standby. it shuts off the screen while using HDMI that way the phone isnt using so much battery because dispite it being charged the screen being on sucks down alot of power. Like 600mA while its being charged at 500mA so that means there is a deficite. Meaning while the power is in its just slowing the discharge

    ^^ I thought since the adapter uses the power connector that battery usage would be a moot point?

    Great app, definitely gonna add it to my list of must haves for this phone.

    One thing however, using MHL requires you be plugged in to the AC charger no? That's 2A not .5A. So even with the screen on, this phones beastly wall charger should put out enough power to charge the phone pretty much no matter what you do with it.

    That being said I will still most definitely get this app for my HDMI-out usages. Thanks

    Update: downloaded it and sure enough my suspicions were confirmed. After reading in the description how it "turns off the backlight" I had a feeling I knew what was going to happen.

    The app doesn't actually turn the display off. The screen is still on, it's just displaying full black. Tested it in a dark room, you can see a slight glow coming from the screen, and pressing the power button causes a substantial drop in darkness to pitch black, meaning screen turned off. So the real question is, what type of impact will this have on battery life, and furthermore does it have any impact on the performance hit we take by doing HDMI mirroring. It obviously takes more GPU power to send an image to 2 displays instead of 1, so I wonder how this really works compared to actually turning the display off. Does the app just place a full black image over our screen, giving the illusion the screen is off? Or does it actually kill all screen draw processing on the GPU, causing an increase in not only battery life but in frame processing performance.

    I'll have to wait till I get my MHL adapter to play around with it, probably try running a Quadrant Advanced with both Mirrored HDMI and with this app running, note any differences, and draw conclusions from there.

    Sorry 500mA is USB ports
    I work for Universal display corp. We devolop OLED tecnology that Samsung uses for their super AMOLED screens. In LCD displays Even if you put a black overlay over the screen you are using alot more power than an OLED because it has a backlight , this is why when you see an LCDscreen with a black screen it glows grey. In OLED screens the chemicals themselves glow so there is no need for a back light, this is why black looks really black the chemicals are not working to glow. So by simply placing that black overlay they are saving alot of power consumption. Despite gpu usage there is a savings.

    be sure to change your hdmi input on the tv itself.

    I am having issues connecting my Verizon Note 2 SCH-i605 using Samsung MHL to HDTV adapter. Everything is hooked up properly. Im hooking it up to a 60" Vizio Smart TV using a HDMI 1.4 cable and the Samsung wall charger that came with the phone. When plugged in phone says HDMI connected but there is no picture. Does the adapter work with 1.4 HDMI cables or should I use a 1.3 or older? Do I need the 5 pin to 11pin aadapter? I do not see anyone else using it demo videos though, theirs seems to work using the MHL to HDMI only. Thanks.

    In the case of the Samsung Galaxy S3 and the Samsung Galaxy Note 2, Samsung decided to move from 5 pins to 11 pins. Since you already have an MHL adapter, you can purchase an adapter tip and MHL should work. Here is a link to the adapter tip for your reference: Amazon.com: Samsung OEM MHL Adapter Tip - Samsung Galaxy S3: Cell Phones & Accessories

    So your saying that the micro usb that plugs into my phone on the mhl cable shouldhhave 11 pins instead of 5? I just got one off ebay and it said it's for the note 2 but I have nothing on my TV screen. The phone is charging from being plugged in but that's all. It's a us cellular note 2 by the way.

    Hi There. Most adapters that you will find on eBay will be 5-pin adapters as that is the original Micro-USB connection. Samsung introduced a new 11-pin Micro-USB connection with the release of the Galaxy S3 and Note 2 (and now with the S4) so you will need to add an "11-pin adapter tip" to make MHL work for the Note 2. You can find them on ebay by searching for "5 to 11 pin converter". Hope that helps.

    My Vizio 47inch 3D tv just won't recognize my Galaxy S4. It says connected but my HDMI input says "No signal"
    I am using the 5 to 11 pin adapter already and other TVs in my house recognize my phone no problem. My Vizio TV just doesn't.
    I tried different methods, different HDMI cables and Inputs and still nothing.
    The weird thing is that it worked just once when playing XBMC. Then I unplugged it and plugged it again it just didn't work anymore.
    I am starting to believe this is a problem with the Vizio TV itself.
