[Q] Problems with allshare Cast Dongle - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

Hi
I bought a allshare cast dongle a while back, used it with some success with my samsung g S3 , but when I tried it out on the Note I noticed a very irritating issue.
Now the TV I'm using isn't brand new , but it's only a year old so it has full HD etc, For some odd reason when I connect the note to the allshare the image doesn't fill the screen . I get a black frame around the image ( no mater what I'm playing off) and the image is shown on both the note and TV at same time ( though with a 3 sec delay)
Now I know this is a resolution issue, but shouldn't the dongle or note scale the image, same way the image of the S3 is scaled up, shouldn't the image of the Note be adjusted accordingly?
Has screen mirroring taken over for allshare cast? I prefered the image only on the tv when connected, instead of having it on both....
Ideas? Suggestions? Rants?

Samsung Multimedia Dock and 4.3 update

I have the Samsung Multimedia Dock (the one with 3 usb port and HDMI), buyed 1 yar ago.
With the 4.3 update I have some problems
with 4.1.2 when i put the note into the dock the screen of the note become mirrored to the tv, with 4.3 update the image disappear on the note and appear only on the tv, but the touchscreen stay active. If i try to watch a video the video is showed on the tv, but control remains on the note (with the screen black) If i disconnect and reconnect sometimes i see images on both screen.
I don't think it's a problem of the dock or an hardware problem of the note, because with an other note2 it works correctly.

LG G5 screen mirror lag

Hello. I'm on my husbands account so I'm a first time poster.
Anyway I hope someone can help me with this.
I have a Samsung smart TV that my husband connects his note 5 to via miracast this is not through WiFi it's direct from the phone to tv.
When I connect my G5 via TV screen mirroring the TV is so laggy it actually freezes almost constantly. Every few seconds it will play and catch up only to freeze again?
Has anyone tried this with their G5, please let me know as I'm desperate!

I've only used screen casting to a Chromecast. Seemed laggy for first 5-10 seconds, then was fine from there.
Have not tried Miracast.

Problem with Screen Mirroring with All Share Cast Dongle on GT-N5100

I have this Samsung Galaxy Note 8.0 (GT-N5100), which had been working quite well before, (including screen mirroring), but I abandoned it for a while. I later decided to be making use of it with the Samsung Allshare Dongle with me, but it started giving me this 'Screen mirroring could not work because if Hardware problems'. I browsed out the solution for that, and got it rooted, so as to fix it, using the buil.prop Es File Manager stuff.
But after all these, It plugs in etc... and turns on, but my tablet still says a "A Screen Mirroring update has been downloaded. Restart Screen Mirroring to update".
I have restarted the dongle severally, so also the tablet too, all to no avail, and I really need to make this work.
Any assistance towards this would be greatly appreciated

Having trouble Miracasting from my s20

Basically my Miracast is worked fine up until a couple days ago when all the sudden casting to the TV just puts a picture of my desktop background at a very low resolution with the three buttons that are on the bottom of my phone at the bottom of the picture on my TV. I'll try to post a picture when I get home. What I have tried already is using an HDMI from my usb-c connection which results in the same thing . Dex mode works fine no issues there just when I try to Miracast
I've tried also casting to my laptop which had the same problem hopefully there's nothing wrong with my phone I just got it.

I can't get the picture to show but that's it

Question Screen Mirroring

Hello all, was was wondering how screen mirroring is working, I tried lastnight to mirror Hulu to my fire stick, but turning on cast i couldn't detect it, also there was no option for me in Hulu. My girl's IPhone 11 was easy to pick it up, sorry in advance if I'm missing any steps as this is my first one plus phone and coming off of a note 8, thanks!
It's a bug, turn on wifi first.
