Mirror

Learn how to view and interact with multiple Android devices in real time directly inside Cellhasher Control.

View of Screen Mirroring tab

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.

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.

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.
