    Default Galaxy Note Pro 12.2: Screen Mirroring not working "hardware conflict"

    Hi,

    Can someone tell me how to operate screen mirroring? I'm trying to connect to my Samsung Smart TV. I want to mirror the screen so I can see the files on the Note.
    I turn on screen mirroring on the TV. Then I do the same on the Note.
    The message on the TV is to turn on the allshare cast. All I get is a "hardware conflict" message on the Note. I've also tried enabling nearby devices but that does nothing either to mirror the screen.

    Allshare seems only to work with photos/videos/music. When I want to share the photos/videos and music, I enable nearby devices and it works fine. No so with screen mirroring.

    Thanks in advance for your help.

    From the manual page 121:

    Screen Mirroring
    To share your device’s screen with another device, enable Screen Mirroring.
    1. From the Settings screen, touch Connections tab ➔ Screen Mirroring.
    2. Touch the OFF/ON button next to Share your device’s screen with another device to turn Screen Mirroring ON .
    Available devices are listed.
    3. Touch Scan to find more devices.
    4. Touch Menu ➔ Help to for more information.

    There is another section in the manual on page 120 that deals with advances settings for nearby devices which may help.

    One other thought, when I asked about connectors, the samsung rep in the local BB said that only the $60 adapter will work, the $40 one won't. Has something to do with the chip inside the adapter. They couldn't get other adapters to work such as rocketfish etc. I have not tried to do a screen mirroring yet but plan on it for a presentation next month so am interested in this issue.

    I tried it with a 2013 Samsung Smart TV which works with my Note 3. Does not work with the Note Pro 12.2

    Root breaks screen mirroring. Un root and it returns. Haven't heard of anyone with a hardware issue running a stock (unrooted) device. Anyone having that issue stock?

    I had a problem when I first tried it using the samsung hdmi adaptor ($60 works but $39 doesn't). I had turned on the screen mirroring on 12.2 and kept coming up with no devices found, unplug connector. End up the problem was forgetting to switch the source on the projector to hdmi instead of computer. Once I did that, replugged the cable to tablet and turn screen mirroring back on it worked fine. Such a simple fix I was muttering to myself "what a dummy, should have figured that one out!".

    For clarification, are you using the term "screen mirroring" as in using an HDMI cable, or via wifi to a samsung dongle?

    Is there a difference in the terms? It does not specify in the screen mirroring section of the manual or on the screen window. Am guessing the term is interchangeable. I used the samsung MHL HDTV smart adapter connecting the 12.2 to a HDMI cable to the projector. I have not tried it with my samsung smart tv because I haven't had a need to do so. Am guessing it would be same hookup if you used an adapter. Have also not tried to use screen mirroring via wi fi haven't the need. On the adapter box it says for connecting MHL enabled phone (whatever that means!) to HDTV or computer monitor. It also says to use standard HDMI cable and micro charging cable both sold separately. When I hooked it up I just use a hdmi cable but no charging cable. I am guessing that if you use it for very long it may drain the battery but am not sure about that.

    As you can see, screen mirroring is an actual feature of our tablet. This particular function is used wirelessly to a samsung dongle connected to your tv. It is connected via hdmi. It basically takes the place of of your cable. So yes, the term can be interchangeable. However, I also have the mhl adapter, and it does not work on my Vizio, but any samsung tv in the house works fine. Yes it will drain the battery.
    Mhl stands for "mobile high definition link" and all tv's are not mhl ready. For some reason, Samsung tv's have no issue. .... Go figure. All you should have to do is plug it to work with a cord.

    So, my tablet is rooted, and I lost the ability to use the wireless feature. I was never able to use the cord and mhl adapted on my Vizio like I said, but while stock I could via the wireless method.

    Thanks for info. I used the screen mirror option in the settings section after I didn't get a response just using the screen mirror on the pull down. That was solved after a few senior moments when I figured out I needed to switch the source on projector. I just tried it with my sam tv and it didn't work. However I do not have the wireless attachment so can't connect wirelessly to internet etc, didn't want to spent the extra $$ to get it and would have had to order it since none were in stock and it was a backorder thing, plus I just forgot about it. I have not dug out a hdmi cable to try it that way with tv. It isn't something that is high on my list to figure out. My main concern was using the projector for presentations. As long as I can get that part to work I am good. Can't give a presentation or class to seniors without illustrations or demos! Makes life much easier, when I can hook up all my "toys" to demo with.

    It does say that not all tvs have the capability to do the wireless so maybe your tv is just copping an attitude with you! I don't root my devices mainly because I haven't found a need to and because it voids the warranty so that makes me gun shy! Must be something in the rooting that takes away some features, maybe it is samsung's way of getting back at you for rooting. That is ashame that you lost that wireless ability just because you rooted it. Hope you can get something working for you.

    Screen mirroring is broke. I'm having the same problem but if I reboot the tablet it'll connect and work fine. Once I disconnect/turnoff screening mirroring I get the same error of hardware connect when I try to connect the table to the dongle and this happens with Samsung dongle and the Startech dongle. Samsung needs to fix them now. I have a galaxy s5 which connects everytime without any errors.

    I fixed the problem by doing a factory reset, now mirroring works fine.

    Default Re: Galaxy Note Pro 12.2: Screen Mirroring not working "hardware conflict"

    I have a factory standard wifi only Note Pro 12.2". I am wanting to send the display to my 22" widescren HP w2207 computer monitor, which has vga and DVI inputs. Had some success with a digitek mhl to hdmi with a hdmi to DVI adapter, but aspect ratio was not good: looked like a 4:3 display on a widescreen tv. Also, this adapter was a 5-pin mhl with a separate 5-pin to 9 pin adapter supplied, but I found this placed too much strain in the connection to the tablet. Needing an 11-pin mhl to DVI, or 11-pin mhl to hdmi, and maybe then use my hdmi to dvi adaptor, or buy a straight lead hdmi on one end to dvi on the other.
    OR, interested if a hdmi to dvi could be plugged into a google Chromecast dongle to feed the dongle to my HP monitor. That is, Note Pro to chromecast to hdmi-dvi adaptor to monitor? Want to get a wide-screen result to my wide-screen HP monitor. I am in the land of Oz (down under) which has just had the Chromecast put on sale in this country.
    Thanks in advance for any help anyone can offer.

    Edit: I now know the chromecast will only receive content from Apps, not the Note screen itself. Am now wondering if the Netgear Push2TV3000 might do the job (again would have to use a HDMI to DVI adapter between the Push and the monitor.

    Also, am wondering whether, regardless of what I use, the difference between the Note Pro screen resolution and my HP w2207 monitor might still cause aspect ratio probs regardless??

    Any suggestions, comments anyone?

    Just a comment regarding screen mirroring quality. I mirrored an HD movie the other day and while it looked fine on the Note it was dark on the TV. I finished the movie using Smart Link and the quality was the same on the TV as on the Tablet....much better than mirroring

    I bought the Samsung MHl adapter and it will not work with my Note 12.2 on my Vizio. Works with note3, and 10.1 2014. I bought my daughter an S4 off swappa and the guy included another MHL adapter with the phone. It weighs twice what the one I bought from Amazon does. I plugged in my 12.2 and it works flawlessly with the Vizio. At least my tv is not broke! Besides the weight difference, I have no idea....they look identical.

    Your setting on your TV [source] must be set to screen mirroring. The wifi must also be enabled on both devices. Make sure note and tv have the latest samsung screen mirror or link app.

    When searching for this issue (sm-t800 unable to start mirroring because of a hardware issue) on sm-t800 (Galaxy Tab S 10.5), this is a recurring return, so am posting here for other tab s users in hopes it finds them.

    Also hoping it helps others out there as well.

    Device -
    4.4.2
    Kernel 3.4.39-2010469
    Build KOT49H.T800XXU1ANFB
    SE = Enforcing

    Rooted 3 months ago using "CF_AutoRoot_Port_T800_BeansTown106.tar.md5" and Odin 3.9 to run XPrivacy.

    Purchased NetGear PTV3000 yesterday and immediately updated firmware to 2.4.53 NP before attempting to connect any device to it.

    Using Rooted Verizon Droid MAXX 4.4 / 19.5.3 / Build SU2-3, Connected without a hitch.
    Using Tab, received the error "unable to start mirroring because of a hardware issue"
    Research on net not so complete for Tab S, but did see 4 things I could try -
    1 - Change HDMI port
    2 - Reset PTV3000
    3 - Modify build.prop to disable HDCP
    4 - Unroot Tab

    Step 1 -
    Fail
    Step 2 -
    Fail
    Step 3 -
    Skip - Wanted to try unroot first, but had modified .prop file waiting.
    Step 4 -
    Booted my device to Download mode, and was verifying unroot steps, when I decided to reboot and backup data. Device wouldn't turn off by holding power, or any combination of 3 buttons, so I connected to computer, and launched ADB to run a reboot. "Device not found" message.
    Launched Odin to see if I could connect. Success.
    Only way to reboot was to issue a patch command, so with the original "CF_AutoRoot_Port_T800_BeansTown106.tar.md5" file designated, ran the root. Success!
    Device rebooted, and tried screenmirroring again..Success!
    Power cycled and tried again...Success!
    Verify Root - Success!
    Verify Maxx screenmirror...Success!

    So, it was either the factory reset on the dongle, or the "refresh" of the original root, but I did not have to change my build.prop file.
    If you have this issue with the sm-T800, and have used the AutoRoot above, just run it again and see if you're functioning (after the reset of the PTV3000 is verified unsuccessful).

    Good luck! Hope this helps someone!

    I was able to finally get this to work. Note Pro 12.2 and Samsung Curved 55" 4k tv. The trick was to use the top screen mirroring icon from the pull down menu. I could not get this to work going through the setting menu as it would time out too fast. When I used the top pull down it seems to last a take little longer to connect. I think someone should review the time-out settings as it seems to be an issue.

    Im not sure what the other issues are but I removed my bluetooth headphones from the Note Pro.

    Hope that helps.

    I have a new samsung galaxy tab pro with android 4.4.2. I am trying to mirror it with my samsung tv. Allshare on the tv did not pick up the laptop so i bought a microsoft wireless display adaptor. When set to screenshare the tv displays the tablet info and the tablet shows the adaptor but then i get a message on the tablet to say that sharing cant be completed because of a hardware error. Has anyone else had this and can advise what i need to do? Many thanks.

    Alright, here is the Fix for this. Please spread the word if this works for you. Because it worked for me. I didn't discover this solution so I can't take credit for this. Here it goes:
    1. On your Note Pro find All Share Cast from Samsung and UnInstall all the updates. Then click Force Close, all of this should be done in Application Manager.
    2. Restart your Note Pro (Very Important)
    3. Using two fingers pull down the main screen from top down to unveil the controls menu. Touch Screen Sharing while the Miracast or other screen sharing service (Wifi Direct etc) is activated on Your TV.
    4. Let it auto find it and auto connect..........Viola!

    Stock SM-P900 worked great with no problems at all using the Samsung Allshare Cast dongle until a firmware update pushed through a few months ago (November 2014 or so). Since then it has worked intermittently between "hardware issue" failure messages, and within the last couple of weeks stopped working entirely giving "Unable to start Screen Mirroring because of a hardware issue" every time. Tried the AllShare Cast uninstall, etc., approach with no luck as well as the other suggestions above for unrooted devices. Hoping for a solution since it was a great feature while it lasted! (My GT-I9195 Galaxy S4 Mini continues to work great with the dongle but it's the SM-P900's screen I want to display on the tv.)
