TeamViewer for Dual-Screen Sharing

Core Functionality:

  1. ✅ Full desktop control (view both host monitors simultaneously)
  2. ✅ Switch between monitors during session
  3. ❌ No native simultaneous sharing (like Zoom's multi-stream)

Key Features

Capability TeamViewer Zoom
————————————————————–
View both screens Yes (as thumbnails) Yes (independent)
Present both screens No* Yes
Resolution Adaptive (max 4K) Fixed 1080p
Cost (Commercial) $50.90/mo $149.90/yr

Workarounds

1. Mirror Displays (Windows):

  1. `Win+P` → “Duplicate” → Share single screen
  2. Shows identical content on both monitors

2. Custom Resolution (Advanced):

  1. Create virtual super-wide display (NVIDIA Surround/AMD Eyefinity)
  2. Share as single screen

Critical Limitations

  1. Attendees cannot choose which screen to focus on
  2. Business license required for professional use
  3. Mobile attendees see compressed view

Best For:

  1. IT support sessions
  2. When control is needed (not just viewing)
  3. Secure external collaborations

Alternatives:

  1. Zoom Multi-Share (better for presentations)
  2. OBS Virtual Cam (free but complex)
