Capture card
Three ways to feed a capture card. Start with display clone; it adds the least delay. OBS projector comes last because it adds the most.
The game's HDMI signal goes into a capture card on the Moonlight PC. There are three ways to feed the card. Try them in this order.
| Order | Method | How it works | Use it when |
|---|---|---|---|
| 1 | Display clone | A second output on the gaming PC's graphics card sends a copy of the screen to the capture card. Your monitor stays plugged straight into the gaming PC. | This is the preferred setup. Nothing sits between the game and your monitor, and no extra software runs on the gaming PC. |
| 2 | Passthrough | The HDMI signal runs through the capture card on its way to your monitor. | Display clone is not possible, and your monitor's resolution and refresh rate are within what the card can pass through. |
| 3 | OBS projector | OBS on the gaming PC sends a fullscreen projector to the capture card as a separate display. | Neither of the first two works for you, for example you play above what the card supports. |
OBS projector is last because it adds more delay than the other two in our tests. It still works well; use it when you need to, not by default.
Whichever method you use:
- Plug a USB capture card into a 10 Gbps port (USB 3.2 Gen 2) on the Moonlight PC, or it will be limited to about 120 FPS.
- Select
1920x1080,240FPS,NV12in Moonlight if the card supports it. A card that captures2560x1440at240FPS, such as the Elgato 4K Pro, can use that instead for more detail; most cards cannot, so stay at 1080p 240 on those. - Close OBS and the card's own software on the Moonlight PC before pressing Start. Only one program can hold the card.
