KDL-43W756C wireless screen miroring very slow

JKoder — Mon, 07 Nov 2016 09:45:19 GMT

Hello,

I have a KDL-43W756C TV that also supports wireless screen mirroring.

However if i connect my laptop or phone ( Lumia 950 continum ) the screen miroring is very laggy, and not usable.

Is there anything that i can do to fix this ?

Does anyone else has the same problem ?

Thank you very much for your time

Sebastian

Hi @JKoder

Wireless Screen mirroring lag is a known issue. No fix yet.

I also have a 30 seconds delay on every action from Windows 10 PC to appear on Bravia KD-55X8508C. It is OK at the beggining but after 15 seconds, delay starts.

Thank you

I hope this is a software bug that could be solved with a new Firmware or new Android OS.

This month we all expect some solutions according to rumurs

Hello,

Did you guys find a solution? I am having exactly the same problem with my Sony Bravia KD-49XD7005.

I am trying to connect my laptop win10 and I am getting some severe lagging, exactly as discribed here.

Please help me, if you have the solution.

Best,

I too am having the EXACT same issue.

UPDATE (I made a video):

https://www.youtube.com/watch?v=TGq4QmRKA3E

Lag grows exponentially worse with my Windows 10 PC. Works fine with multiple phones, though sometimes YouTube phone controls stop working mid-videos.

Changed the channel of the router. Reset both devices. My Dell XPS 15 is brand new. This is one of the first things I was testing. Any help would be lovely! This sucks.

You all have to start thinking that if two devices do not work with each other the problem can be in whichever side or in the communication media (wifi in this case).

Said so you have two possible workaround:

- on android tv avoid completely miracast protocol. Use chrome function to mirror your desktop via the Google cast protocol . It is easier faster and works always.

- you can try to set a parameter for the authentication from win10 that solved the problem on mine a1 (it should be present also on non android platform)

Setup->network>domestic network->IP control->Simple IP control->enable

I am not sure of the translation but should be something like this and cannot guarantee it works also for you since miracast a a flaky protocol

reading back in this forum, this is a problem with the sony tvs for
multiple years now. the issue is the mirror cast establishes, yes
there's lag, but that's not really the issue, the trouble is the screen
freezes for about a second every 20 seconds or so, enough to make it
unwatchable. people in this group have been complaining of this issue
going back 4 years or more, I myself have had the issue for 3 years, the
trouble exists with laptops iphones and android devices. I've tried them
all. the common link is the sony tvs. since sony blames other input devices
for their interface issue, I have found a fix on my own.. My new TV is a
Samsung, it works great, Ill be replacing my other sony tv with a Samsung
as well.

Got a Sony XBR-65A8G recently and tried out the Screen Mirroring feature using my windows 10 Laptop and encountered the same lag everyone is talking about. It is weird that Chromecasting from a web browser works better than Miracast. Could it be that Sony ATVs don't have Miracast hardware/services that can handle the miracast protocol.

Also @rooobb could you expand more on the second option you suggested. What do you mean by "set a parameter for the authentication from win10" and "Enabling Simple IP control"

@naija_chinex simply enable the setting I indicated (still not sure about the translation from Italian)

Setup->network->domestic network->IP control->Simple IP control->enable
