Maybe someone else had the issue and found a solution.
Nvidia Shield TV connected to a Samsung 4K TV.
System resolution set to 4K@60p (recommended)
Here are the symptoms
- During playback of some videos a horizontal tearing line appears after a while (about 30-40 minutes)
- the line moves slowly up and down the screen
- it is a tearing line, meaning the upper part of the picture is slightly in a different position than the lower part
- pressing pause shows no line
- stopping the video playback and resuming it, fixes the issue for about 30-40 minutes
- not every type of video is effected, 25p files are, 24p seem to work without issue
Things I tried
- VBS Settings in Kodi are not effecting ths issue (appears with on and off)
- Kodi is set to allways sync refreshrate of TV and it works (Samsung switches to 50p for the 25p files)
- Kodi is running in latest beta (16 beta 4)
- Shield is updated
- Motion correction/smoothing is deactivated in TV
- tried the Kodi option to sync video to refresh rate, no effect
This is an issue which is normally caused when vertical synchronisation is turned of. Please make sure it is enabled.
That was my thought as well, first thing I checked. I did try to explain it with the first line under "things I tried". The same symptom with this horizontal tearing line appears when VBS (vertikal blanc sync) is on or off. No effect.
So far the issue is only present on 25p material (TV shows und TV recordings, usually mkv files, not live TV)
So just in case anyone else needs the fix, here is what worked for me
Symptoms
- 25p files in kodi will cause the TV to switch to 50hz
- after a while 25p files will show a horizontal tearing line
- also after a while the playback of 25p files will start to judder
Solution
- normally Kodi should switch to 25p by itself, but it doesnt
- normally 50hz should not cause issues for 25p playback, but it does
- we need to force Kodi to switch the TV to 25hz
- create a textfile named advancedsetting.xml with the following content
Quote:<advancedsettings>
<video>
<adjustrefreshrate>
<override>
<fpsmin>24.99</fpsmin>
<fpsmax>25.01</fpsmax>
<refreshmin>24.99</refreshmin>
<refreshmax>25.01</refreshmax>
</override>
</adjustrefreshrate>
</video>
</advancedsettings>
- now copy the advancedsettings.xml to a usb stick or drive
- plug the usb stick into Shield TV
- copy the file to Android/data/org.xbmc.kodi/files/.kodi/userdata/
- path might be a bit different depending on version
- you can use the Android App ES File Explorer to copy the file
- when you cant see the path, activate the option to show hidden files
