I setup Moonlight TV for a friend on his TV and encountered a pretty bizarre issues. It will work only when set to a very specific set of setting which are these:
These settings work every time but if the bitrate is set to 34000 for example Moonlight will try to connect, then show a black screen with the "Unstable Connection" info and then disconnect. Same if I try to set the FPS or resolution value to anything other than 1080p 120hz. Even going down to 30fps doesn't work. One time I managed to connect with 1080p 60hz 20000 bitrate but the connection only lasted for a few seconds before dropping again. 1080p 120hz 35000 was stable for an hour or more.
If I change the video-decoder to SMP it also only connects with these specific values but shows a black screen. The overlay shows that the stream is connected but nothing but a black image is received even with HDR and h265 off. I know his webOS version is too old for SMP with h265 and SMP.
Now 1080p 120hz would be enough for my friend but we ideally would like to drop down to 60fps as the Network FPS shows that it mostly just hovers around 78fps resulting in a pretty juddering experience even with 60fps games. The RTT latency was 1ms through the bank.
It's just bizarre to me that we can't go anywhere lower from 1080p 120fps 35000.
Specs of the host PC:
CPU: Intel i7 6700
GPU: GeForce 1070 Ti (Driver version: 511.79)
OS: Windows 11 Pro RTM
Refresh Rate: 144hz
G-Sync: Compatibility Mode enabled
Connection: DVI --> HDMI
Refresh Rate: 60hz
We already tried dropping and matching the resolution and refresh-rate of the monitor to match, disconnecting one or both monitors and rebooting all devices several times, Moonlight will still only work with these specific settings.
PC -- (LAN) -- Router 1 -- Wall LAN Plug -- Router 2 -- (LAN) -- TV
With Wall LAN Plug I mean actual LAN ports in his apartment walls not DLAN Powerline so effectively it's a straight wired connection between all devices.
If I can provide any more information to solve this issue please let me know and I'll contact my friend.
And of course thanks for the hard work making all this possible, it was a bit mindblowing seeing Moonlight running directly on the TV :) If we only could get 1080p 60 or 4k60 working it would be perfect.
