Black screen on any resolution above 1080p

[beeeeswax]

Describe the bug If the streaming resolution is set to 1080p everything works fine but at 1440p or 2160p all I get is a black screen. I can hear audio (Steam Big Picture navigation sounds) when this happens so I know moonlight is connecting and receiving a stream.

Streaming from the same PC to the same TV via an Nvidia Shield Pro 2019 with Moonlight works fine at 1440p and 4k.

Problem is the same whether video format is set to HEVC or H264, 30/60/120 FPS within Moonlight UWP.

Captured some log info via Google Lens:

Logs and info don't appear immediately once enabled so this is what I see when I enable logging, disconnect from the black-screen session then reconnect:

I got the same thing here, only works on 1080p

Hi everyone and sorry for the late response.

Checko that you are using HEVC as a codec instead of H264

[beeeeswax]

Problem is the same using either HEVC or H.264. A stream is opened because I can hear Steam Big Picture startup and navigation sounds when moving the controller but screen is completely black,

[andremoreirafulfil]

I've tried to use another resolutions and different codecs, now it works fine what ever resolution and codec I chose to use

What exactly did you do to fix it? No matter what video encoder I use, I get a black screen on anything over 1080p. Are you saying you can now stream in 1440p and 2160p?

[andremoreirafulfil]

I'm not sure what exactly fixed it, but I was trying a lot for combination of resolution and codecs, then now I'm able to stream 4k 60fps in xss.

I remember I set it to 720p, then I changed codec and tried to put 4k then it works fine for me

Well I'm glad you fixed your problem but I've just spent the last 10 minutes flicking between different resolutions and codecs and no matter what I do, as soon as I select any resolution above 1080p, I get sound but a completely black screen.

I tried jumping from every 720p/1080p/H.264/HEVC combination to every 1440p/2160p/H.264/HEVC combination in different orders, trying the "Disconnect" and the "Disconnect/Close" options between changing resolution and nothing works. I have 2 Series X consoles in the house and they both have the same problem, there's something wrong here. Is there nothing useful in the logs I supplied?

[beeeeswax]

OK, my mention of this happening on both my Xboxes prompted me to look at my Sunshine config more closely and I've solved the problem. My sunshine server was set to not advertise HEVC support (due to issues with it on other Moonlight client platforms). Having now set the following options:

HEVC Support Sunshine will advertise support for HEVC Main profile

Force a Specific Encoder NVIDIA NVENC

I can stream at 1440p/60/120 and 2160p/60/120. Thanks everyone for your input, it helped me get to the bottom of this.
