Streaming error TVAPP-00236 - unsupported display

I have been using xFinity streaming successfully for years, and suddenly I have a problem today.  My setup has not changed, I have not installed any new software, there have been no changes to my network.

 

I have a MacBook Pro (2019), running Catalina 10.15.5

Running Safari 13.1.1

External display is a Cisco DX80, connected via (genuine) Apple display adapter and HDMI

 

When I try to stream content while the external display is connected, I get error code TVAPP-00236, with the message that my display is unsupported and I should connect a supported display or use an Apple display adapter.

 

I have rebooted both the MacBook and the DX80.  I have plugged the display adapter into each of the four USB-C ports on the Mac.  I have tried another Apple display adapter, all result in the same error message.

 

Hmmm, well, this display, in this very same configuration worked just fine yesterday (and for a couple of years), and I AM using an Apple display adapter.

 

Streaming works just fine if I disconnect the display (however, that is not ideal, since I need the display real estate.)

 

Thanks in advance for any insight into what might be happening here, and potential fixes.

 

Thanks!

are you using a chrome browser and the tv.xfinity.com web site? or are you trying to use an app?

I'm having the same issue.  Worked fine for years, then suddenly I can't stream live TV on my iMac.  Did you find a solution?

Some people prefer to not use a bug infested, information gathering hog called Chrome.  This is not helpful.

Re: Streaming error TVAPP-00236 - unsupported display

I just fixed my issue with this error.  Looks like there was 2 issues going on. 

 

1.  I have another TV (not connected to xfinity) connected to my iMac as a second monitor.  It is connected via a lighting to HDMI cable.  Brand new LG TV.  So I disconnected it, and the problem got better but still didnt take care of it all.

 

2. This is what really helped alot of issues.  I had installed Adobe flash a few years ago, I thought I had updated to current version.  I just removed it.  And so far all the sites that have video content work So Safari may not need adobe to play flash content now?

 

So uninstalling Adobe, and removing the second monitor cable proved to resolve this issue.

I still dont know why removing the second montior (TV) had any reason to cause issues.  Still working on a solution to have my TV connected to the computer at the same time able to watch on Xfinity Stream.

Re: Streaming error TVAPP-00236 - unsupported display

I couldn't find an answer using Safari, but switching to Firefox worked.  Not ideal, but back viewing.

Re: Streaming error TVAPP-00236 - unsupported display

It appears to be a compatibility problem with Safari, Xfinity and Flash Player.  It's got to be something that was changed on Xfinity's end;  I've been using the same setup for several years to watch TV on my desktop iMac, and it's always worked.  I got a new computer  back in December, and it worked fine until last week.  Now I'm getting this error.  What's weird is I can still go to various network websites and watch there, and I have to sign in through Xfinity.

I beleive it has to do with xfinity not keeping the software compatible with all user's - it is not the first time and it will not be the last.

Firefox is an open source product and is not affiliated with Apple - Safari is an Apple product and is maintaned by Apple.

Re: Streaming error TVAPP-00236 - unsupported display

I have the same exact issue. Mac Mini digital display via Apple connection Safari - has been working fine since last year - stopped working this week. No changes to software or hardware - suspect: xfinity.

 

I called xfinity and got a wierd runaround (they were telling me about an outage that would be fixed - while I was watching ESPN...hmmm)

 

xfinity should fix problem.

 

On Safari: NBC works, ESPN works (probably others) MSNBC and CNN do not work

  WHY???

 

On Chrome: the above 4 Channels work

 

This is an xfinity problem...

I just started having the same problem and cannot connect to Xfinity TV Streaming with my iMac Mini.  I removed Adobe Flash Player as someone else suggested and that did not fix the problem.  For the cost of cable TV through Comcast we should be able to recieve the services we are paying for.  Other than exchanging text with a robot we should be getting real "SERVICE".

Re: Streaming error TVAPP-00236 - unsupported display

Hello,

 

We have recently updated our Web Application which transitions playback from Flash to HTML5.

 

HTML5 playback is not compatible with older Mac versions, requiring at least Mac OS 10.14.4 (this can be updated in the App Store) and Safari 12 or 13.

 

If you are experiencing trouble streaming to a second monitor or display, ensure that you are using HDMI, DisplayPort, or a certified Apple adapter as other connections may be unsupported for HTML5 playback.

 

Alternatively, you can try streaming from a different browser such as Chrome, Firefox, or Edge.

 

Thank you for your continued feedback and let us know if you have any additional questions or concerns.

Re: Streaming error TVAPP-00236 - unsupported display

My Mac is 10.15.5 and Safari 13.1.1.  Since these are up to date and used by 90% plus of all Mac users, it makes no sense that they would not be recognized by Xfinity.  The sad thing is that I am not surprised.

 

I do appreciate your quick response.  Thank you.

Hello @gtower,

We are sorry for this frustrating experience but thank you for your patience and for providing us with this information.

We can see when your device has experienced the TVAPP errors and confirmed that they occurred after update to the latest Web Application. We would like to investigate further but will require some information on what display you are attempting to stream on - such as the make and model of the display and the cord used to connect (if using an external display).

Re: Streaming error TVAPP-00236 - unsupported display

It is an Insignia Model : NS-19E310A13    The model does not support HDMI so it is connected via an adapter.  I was able to watch CNBC daily until maybe a week ago.

Re: Streaming error TVAPP-00236 - unsupported display

Just started having this problem today, after a long time of no problem.

~~~FIXED IT~~~

--Using Safari.

--On MacBook Pro with HDMI adapter (non-Apple) going to TV/monitor for second screen. 

--Got the error on both screens trying to watch Xfinity through Safari (though Opera was fine).

FIX: I quit Safari first. Then I disconnected the HDMI adapter from my MacBook, waited a few seconds, then plugged it back in. Then I disconnected the HDMI cable from the adapter, then plugged it back in.

Started Safari. Brought up Xfinity stream directory. Chose a show to play. NO MORE ERROR.

Thanks for the suggestion.  I gave it a shot but it did not work for me.

Same here.  Looks like my adapter is a third party;  I don't see an Apple emblem on it.  I still don't see why that would matter.   I can stream content from other websites just fine.

Re: Streaming error TVAPP-00236 - unsupported display

Hello @gtower,

We have looked up the monitor model and it appears that you can only connect via VGA adapter, but please correct us if we are wrong.

Unfortunately, this playback on Safari requires HDMI or Displayport connection. You may be required to try a different monitor or use a separate browser.

Re: Streaming error TVAPP-00236 - unsupported display

What I don't understand is why I can't use the iMac's native monitor.  That makes no sense.

Re: Streaming error TVAPP-00236 - unsupported display

I am still having trouble.

 

The lastest verson of Safari 14.0.1 and macOS 10.15.6.  I can playback video just fine if my second monitor is not connected.  So, browser obviously works so to heck with the idea that there is a flash vs html5 TS-Stream going on and at fault.  This is just another dodge of the issue saying that it's a problem with the end user and not taking responsibility for thier own problems.

 

If it was my browser or OS then why can I play it without second monitor/TV??  That is the question.

 

When I want to view a program, I have to disconnect the second monitor.  I am running apps in my day to day work that require second monitor, so I gotta stop working just to watch/listen to a show in the background?

 

I guess the technician will come back, oh but you have an iPad or iPhone that you could watch it from.  Well yea sometimes... But I grew to like the webpage i could load up on the mac and watch a show or just listen to it while I am getting other things done.  Now, you have me re-configuring my apps every time I disconnect my secondary display adapter.   Just not convient like it used to be.  And it's not on my side.  Some property is changed on server side.
