Anyone getting "Screen Tear" from their videos on a HDTV?

  • Not a Problem
We are having a problem with "Screen Tear" on our videos being displayed on our HDTV's. 
It shouldn't be from our transcodes, but we transcode to WebM at 1920x1080, 10Mbps, VP8 and/or VP9. And MP4 at 1920x1080, 10mbps, H.264.
Our HDTV's are Samsung at 60Hz.
We have the latest player updates.
High quality Rosewill HDMI to Mini Display cables.
Any settings on the Intel NUC, i5?
And the problem is intermittent. Sometimes bad screen tear, sometimes not.
Any help is appreciated.
Thanks.
Brian

Hi Brian
Are you able to pass on the name of the presentation/video that is showing the issue (or the most issues ie in terms of frequency?) and I will see if I can recreate this here. And is the Display the most recent one in your account (ie Stokers Office 1080p)?

Thanks!

Can you send me a direct email. I have some files to send to you.
The video files as well as a quick video i shot of our HDTV with the screen tear.

Thanks,
Brian

I have made a copy of the Stokers Presentation to my own Display but getting an error with video playback, looks like it is due to the files being inaccessible outside your network ('server DNS address could not be found'). There is also some custom code within the presentation HTML. I am wondering - are you able to see the test the videos by themselves with the Video Widget only and without the code? I am wondering if there is some sort of rendering performance with this from the code (although, cannot tell due to being unable to access the presentation). Thanks!

I sent my files to support@risevision.com and put Alan Clayton in the subject.
The files are explained in the email.
The custom code has to do with our IT department. We have to have the code there for a "winner screen" that comes up at various times on the Casino floor and it bypasses RiseVision and displays a background PNG file with some text, etc.
Our IT department can explain that better if you need more information on it.
So we have to have that code in place. 
We could test it i guess but in the end, that code has to be there.
Like i said in my email i think it has to do with our players using Linux. And from what quick Google searches i have done with Linux/Screen Tear, it sounds like its a common issue.
Not sure if there is some definite fix, but our IT guys are forcing vSync and some other options with turning tearing features on. More of an IT thing, i am just the graphics/video guy.
But thanks for the help.
Check out those file and let me know what you can make of it.

Hi Brian,
I responded back to you via the support channel since i've added screenshots of your Display (and in case you did not want to show it to the public). It might also be worth (if that is OK) to post a photo or two in case others in the Community have run into the issue that you are having.. thanks!

Hi Brian,
I couldn't recreate the issue using the latest Rise Player and the video samples provided. Can you also try with a better video card or an alternative monitor? Thanks!

Our monitors are not the problem, its the HDTV. We use higher end 4K monitors and they play fine with no screen tear. But i am sending the signal out mini display to HDMI to the HDTV, not to a monitor.
Our video card (Intel HD 6000) should be plenty on our NUC5i5RYK.
Our IT department is building a windows version to test since it may be our Linux build? Not sure.

Brian,

I've never seen the issue be related to the OS in my experience, typically when I have run into Screentear, it has always been due to poor cabling or insufficient hardware.

I'm very curious to hear if switching to Windows fixes it.

Thanks!

I have tried 3 different cables. Rosewill and other brands. Mini Display to HDMI and also mini HDMI to HDMI. All have screen tear. 
Is the Intel HD 6000 not a fast enough graphics card?

Brian,

I doubt the issue is the cables then, especially if you are seeing it with 3 different ones. Googling some quick reviews of the Intel HD 6000, it looks like it should work for your needs: http://www.digitaltrends.com/computing/three-generations-intel-hd-graphics-tested/#:HpXJAwPVLQKYNA

Let us know if switching to Windows helps!

Robb,
We have since done some Windows builds and the screen tear is about 95% gone. I notice a very minimal tear but completely OK. Not sure what the deal was with our Linux builds, but seems to be OK for now. I am letting this play over the weekend and see if anything freezes up which was another problem we were having.

Awesome.

Thanks for letting us know Brian! I was very curious to hear if Windows would solve this or not.

A NUC i5 with Intel HD 6000 Graphics is overkill and under Windows should handle video cleanly on up to 2 or 3 monitors at full 1080P resolution. 

Get latest Intel Drivers as a start.

Try a wired Ethernet connection to isolate if it's a WiFi issue, it seems that can momentarily stall video and cause some jerky or tearing behavior.

If it's clean with wired Ethernet and you must a WiFi connection try an external USB WiFi adapter to get the antenna in clean air and also make sure your WiFi isn't overloaded with a ton of other users. We've had some cases where we installed a WiFi Access Point and limited it to just a sign or two.

Good Luck

We have NUC I5's for each individual HDTV, no monitors. All at 1080p, 60hz. 60 of them.
Latest drivers.
Wired connection, ridiculous speeds here.
But still not sure how a 10Mbps bitrate is causing jerky playback.
My speeds and hardware in 1999 could play this. Standard H.264 and/or WebM files.
Since going to Windows, its seems to play a bit better.
I am just the graphic artist/multimedia guy at my work so i am sure IT can explain the more techy stuff a bit better.
But...
This should be working plenty fine with what we have.
Since switching to a Windows build, it has been better, way better.
Thanks though.

Brian,

Have you tried running the video outside of the Rise Vision Player? If it is obvious is a Player that is not Rise Vision, at least them you know it is the file itself.

Thanks!
