I am having an issue with playing Netflix content through Safari since upgrading to Yosemite. Specifically, Netflix will start to play the content and then display an error after a few seconds. The error reads "Whoops, something went wrong... display error. There appears to be a display problem. Please ensure your monitor is HDCP compliant and is not mirror using airplay."
My monitor is HDCP compliant (HP ZR30W) and it's the only monitor connected to my 2014 MacPro. I presume this is an issue with the latest version of Safari and all the next extensions Apple added to support Netflix streaming without the Silverlight plugin.
What has changed all of a sudden that we get these HDCP errors. I was watching Starttrek discovery when suddenly after about 5/10 minutes of play it stopped and gave me this error. This must be a bug in Safari / OSX and or Netflix. I never had any problems before today using netflix on my mac.
The problem still persists with MacOS 10.13.2 and Safari 11.02. I suspect that Apple is not interested in fixing the problem: too busy selling iPhones. I've had no problems with Chrome and Netflix. Maybe Apple will realize that first you switch to Chrome then to the Pixel phone then to those (relatively cheap) powerful Windows machines.
Carolyn - My Silverlight plug-in was already properly configured. With Yosemite & Safari 8.0, Netflix no longer uses Silverlight. Instead, it plays content using HTML5. So, the plugin should not be the issue.
Actually, I posted the same question a few days ago, this is how I fixed it: Enter Netflix and go to your account, then to your profile, then to Playback settings and there, uncheck the bottom option (prefer HTML5 instead of Silverlight), you should be able to play movies again... obviously, you have to have Silverlight in your computer.
I'm running into this same problem. I also recently installed Yosemite. For me though, it stopped working when I updated my Adobe Flash plugin today. Although, I'm not sure that should be related. Switching my netflix preference to Silverlight, as was suggested above, worked and now I can play netflix again. But This seems like it should be unnecessary.
Unplugging the second monitor from the thunderbolt-VGA adaptor fixed the issue, and now Netflix plays with the HTML5 setting turned on! So it would appear that the second monitor was the problem. Which would track with what this page says:
The page states that a Thunderbolt-DVI connector should work. Luckily this monitor has both, so the next thing I will try is to buy a Thunderbolt-DVI adaptor and retest with both monitors attached (I don't have one at the moment). If that works, I'll post the results, maybe next week.
This kind of stinks because I've always been two-monitor dude, I like having a movie playing on one monitor while I work on the other for example. For now, until I get the adaptor, I'll switch netflix back to using silverlight, which seems to still work with both monitors attached.
This issue only occurs on my desktop MacPro. I also own a MacBook Pro. If I change the Netflix HTML5 settings, then my MacBook Pro will lose the benefit of HTML5 and longer battery life. Of course it doesn't matter too much for the desktop MacPro.
My monitor is HDCP compliant as well and I only have one connected. It's connected by a third-party Thunderbolt-to-DisplayPort adapter (not mini-displayport). Maybe I should try the HDMI and see if it works, although I hate HDMI. Thanks for the idea!
While this workaround may work, you should not be forced to use one sort of monitor or another with a computer that you own. If you google HDCP, you'll see that it's been broken since before it was actually released and therefore serves no purpose other than to annoy and antagonize legitimate users. It is totally unacceptable to me that Apple is doubling down on this technology with Yosemite/HTML5. I have an old projector that still works great with DVI but does not support HDCP. That means I can't watch iTunes videos, and now apparently can't watch HTML5 videos. I am certainly not about to replace working technology because of a software problem. What a waste.
I built a PC yesterday with the Asrock J5005-ITX motherboard. It's advertised as having HDMI 2.0 and supporting 4k @ 60hrz. This is true but I can't seem to get 4k for Netflix. I've updated Windows 10 and all of my drivers. Also, I installed HEVC video Extension from Device Manufactures but I still can't get it to works. I'm getting this error message in the netflix app: Error code: U7361-1255-C00D7159. I just wanted to know if this CPU supports 4k / UHD Netflix.
So did you guys get the Asrock J5005 to stream Netflix in 4K. I downloaded and updated my BIOS to 1.30 and I still can't get it to stream Netflix in 4K. Did you need to use the Microsoft HEVC video extension. Also I was only able to do the BIOS update by the instant flash. Shorting the TXE pins did not work for me. Any help would be appreciated.
Thank you but it still doesn't work for me. I have a LG OLED B7 and I tried all the HDMI ports but I can only stream Netflix in 1080p. Netflix will stream in 4K when I use the app on my TV but the app on the computer can only stream in 1080p. There
