As the subject states, I get no video on any material, but I get audio. The screen is just black. This happens on HTPC for Windows and the Windows App. It works fine when using Plex Web.
I also have an Nvidia Shield and a system running OpenPHT and they both work.
Are there some Microsoft Visual C++ packs that need installing?
Do you have Direct Play and Direct Stream enabled in settings?
Using a different computer, would you screenshot the dashboard for us when it’s giving you a black screen on Windows?
On the HTPC and Windows App, try to toggle the Insecure Connection setting and retest.
Would you power cycle your windows machine, start HTPC, make the issue happen for 30sec, quit HTPC, and grab us the Plex HTPC.log?
Would you please enable IPV6 on my Starlink?
Thanks <3
Do you have anVidia GPU and an integrated GPU as well?
If so, try forcing the nVidia GPU via the compatibility settings of the app shortcut.
Do you have a nVida GPU as only GPU?
Did you perhaps force antialiasing as a global ON in the preferences of the nVidia control panel. Try resetting the global preferences to default and enforce any special GPU features only for specific apps which need them.
Thanks to both nibbles and OttoKerner for the rapid replies. I have only an RTX 2070 Super and before seeing your responses, I have solved it. Noticing some other odd issues like Nvidia Control Panel closing whenever I tried opening “3D Settings” and random reboots during games, I suspected overheating of the GPU, but placing a monitor on it, I was pretty sure it was not.
I had noticed odd behavior after updating to the latest Nvidia drivers, so I used DDU and NVCleanstall to clean the system and reinstall drivers. Without changing any settings, tested both Plex HTPC and Windows App versions and they both work.
Thanks.
I’m having the same problem as in the subject, but unlike OP this system only has an Intel iGPU.
It’s also my main playback machine and has been trouble free other than one other time the same thing happened–months ago. I don’t think the problem is the files either because I’m testing with files that played ok before. I’m also direct playing so transcoding isn’t a factor.
What’s pretty weird is that sometimes, it will start playing and then freeze. If I stop playback it will return to the menu. If I start playing something else, I see the frozen screen from the previous playback attempt. I have to restart the app to play back any other files.
Test the various settings of the “Playback Quality” selector.
Do also toggle the “Hardware Decoding” checkbox back and forth.
Then re-test after each change.
Turns out that disabling Hardware Acceleration let playback resume normally. No idea if it’s Plex, Intel, or Microsoft at fault.
There’s nothing weird about the system, it’s Win 10 on older hardware with standard drivers. If there was ever a “boring” Wintel system, this would be it.
