### Interface Overview

From this page, you can:

* Mirror one or many devices simultaneously
* Interact live using tap, swipe, scroll, or type actions
* Adjust frame rate (FPS) and bitrate (Mbps) for performance or clarity
* Manage individual or grouped mirrors with quick start/stop controls

#### **Mirror Modes**

* **Single Mode:** View and control one device at a time
* **Multi Mode:** Mirror and interact with multiple devices simultaneously (performance depends on your GPU specs)

#### **Settings Controls**

Fine-tune your stream for quality or performance:

* Frame Rate (FPS): Adjust smoothness (default 15 FPS)
* Video Bitrate (Mbps): Adjust video clarity (default 1.0 Mbps)

Restart mirrors to apply changes.

#### **Mirroring View**

During an active mirroring session, each device is mirrored in real time, you can:

* Interact with the screen (tap, swipe, pinch, type)
* Resize or rearrange mirrored windows

#### Detach

Detach mirrors into a new window using **Detach** for split screen or multi-monitors.

> **ℹ️ Upcoming Enhancements**
>
> Features are actively evolving. Future updates plan to include:
>
> * Group Control Gestures — Control multiple devices with a single user-initiated touch or swipe.
> * Automated App Launch — Start identical apps across all mirrors at once.
> * Optimized GPU Rendering — Seamless support that consume less GPU resources.

### How to Mirror Devices

1. Connect your devices (via USB, Ethernet, or Wireless ADB).
2. Open the **Mirror** tab.
3. Choose Single or Multi mode.
4. Select the device(s) you want to mirror.
5. Adjust FPS and Bitrate if needed.
6. Click **Start Mirror**.
7. Interact live on-screen — all actions are reflected instantly.

### Recommended Settings and System Requirements

Each active mirror consumes CPU and GPU power. If you experience lag:

* Lower the FPS (10–15 recommended)
* Reduce Bitrate (0.8–1.0 Mbps)
* Limit the number of simultaneous mirrors

| Number of Devices | Recommended GPU                                                | Expected Performance                                                                         |
| ----------------- | -------------------------------------------------------------- | -------------------------------------------------------------------------------------------- |
| 1–20              | RTX 3060 / 4070 / RX 6800+                                     | Ideal for enterprise or mining cluster visualization                                         |
| 20–100            | RTX 4080 / 5080 / RX 7900 XT or greater                        | High-end scalable performance for extensive clusters, with 60+ FPS in complex visualizations |
| 100–1000          | RTX 5090 / A6000 or multi-GPU setups (e.g., 2+ high-end cards) | Enterprise performance for massive data center-scale operations                              |
| 1000+             | High-end Multi-GPU installation                                |                                                                                              |

### Troubleshooting

> **Black screen /** **No feed**
>
> * Check your Scrcpy path in Settings → System Paths to see if it's correct. See more in [settings.md](/docs/cellhasher-control/tabs-walkthrough/settings.md).
>
> **Lag or slow responses**
>
> * Most likely is too high of FPS and bitrate causing low GPU resources. Try redcucing FPS/Bitrate and restarting all mirroring sessions.
>
> **Sporadic touch response**
>
> * Your device may be experiencing "ghost taps" from the metal chassis caused from imperfect grounding. This can happen if the Cellhasher is plugged into a power strip or outlet adapter.
>
> **Mirror stops randomly**
>
> Low GPU resources or a sporadic USB or wireless connection may have halted the stream and you need to intiate a refresh using the refresh button on the device card, or refresh all at the top of the pgae.
