How is video latency while streaming on webOS?

On 1080p it's usually 30ms, and 70ms on 2160p. Moonlight itself doesn't take too long to submit one video frame, so this might be the best your TV could do.


Why I didn't get 4K120fps, instead there is only 70~90fps?

Moonlight can decode 4K120 if your TV supports it, but your GPU may not capable of encoding 4K120 video at full speed. You can check decode capability by dividing 1000 with (receive time + submit time), if it's more than 120 then the problem is on your host side.


Can I have higher framerate than 65mbps on webOS?

No. webOS TVs can only handle 65mbps at most. In fact, you'll get performance issue over 45mbps. Sticking with default bitrate will usually give you a good balance between performance and quality.


I didn't see my computer! And I cant add it manually either.

Please make sure your computer and the TV are in the same network. If your network looks like following graph, then Moonlight can't find your computer by default.

graph TD;
    A[Main Router]---B[Ethernet Port 1];
    A---C[Ethernet Port 2];
    B---E[TV];
    C---D[Second Router];
    subgraph Secondary Network;
    D---F[Computer];
    D---G[Other Devices];
    end;

Frames are dropped frequently. How to fix that?

A: There are 3 things to consider.

  1. Lower your bitrate. On webOS video stream over 50~60 mbps will have significant lag or simply not work, and 35-40 mbps seems to be a sweet spot for quality and performance.
  2. Watch for Wi-Fi channel. I have observed high latency if the TV is in certain channels, presumably DFS channels. Depending on where you live, trying a non-DFS channel, or use Ethernet might be a good idea.
  3. Choose a better decoder. NDL will always have better performance than SMP. Although sometimes it doesn't have H265, or HDR.

Can webOS version have surround sound?

A: Currently no. Despite many different approaches have been tried, it turns out none of them works on webOS. So there's only stereo on webOS at this moment.


Can I use my favorite game controller?

A: Yes. Please keep in mind that for some of them you'll need an adapter, see this page.


Will this be available on LG Content Store?

A: Short answer: Not likely.

Long answer: Moonlight-tv is not built with LG's SDK. Instead it's built with Unofficial SDK. LG is not very positive when I reach them, they ignored my request after a few emails. But fortunately with this desktop tool installation become much easier.
