Remote Sharing: TeamViewer vs. Zoom
**TeamViewer Model (Host-Controlled Sharing)**
```flow st⇒start: Host shares invite op1⇒operation: Guest joins session op2⇒operation: Host sees ALL guest screens op3⇒operation: Host takes control (if permitted) e⇒end: Session ends
st→op1→op2→op3→e
st⇒start: Host creates meeting op1⇒operation: Guest joins meeting op2⇒operation: Guest CHOOSES what to share op3⇒operation: Host sees only shared content e⇒end: Meeting ends
st→op1→op2→op3→e
Remote Dual-Screen Access (CA → TX)
Core Requirements
1. View both Texas PC screens simultaneously from California 2. No reliance on remote user interaction after setup 3. Sub-200ms latency for trading responsiveness 4. One-time or low recurring cost
Best Solution: **Parsec + Multi-Monitor Tools**
Low-latency professional solution
Setup: 1. On Texas PC (host):
- Install Parsec
- Enable “Hosting” in settings
- Configure `monitors.xml` to share all displays
2. On California PC (client):
- Install Parsec
- Connect via host's peer ID
- Use `Ctrl+Shift+Alt+M` to toggle monitor views
Performance:
| Metric | Value |
| —————– | ———————— |
| Latency | 80-150ms (CA→TX) |
| Bandwidth | 10-25Mbps (dual 1080p) |
| Cost | $10/month (Pro) |
Alternative 1: **RustDesk (Self-Hosted)**
Free open-source TeamViewer alternative
1. Set up RustDesk server on AWS Texas VM 2. Configure `hbbr` (ID server) and `hbbs` (relay) 3. Connect directly via Texas IP (bypassing public relays)
Advantages: - Full control over encryption - 120-200ms latency - No subscription fees (only AWS VM costs)
Alternative 2: **Splashtop Business Access**
Optimized for financial use
1. Install Splashtop Streamer on Texas PC 2. Enable multi-monitor mode in settings 3. Access via California client (thumbnails or combined view)
Trading-Specific Features: - 256-bit AES encryption - File transfer without VPN - $8.25/month (billed annually)
Critical Comparison
| Solution | Simultaneous View | Latency | Max Resolution | Cost |
| —————- | ——————- | ——— | —————- | ————— |
| Parsec Pro | ✅ (Independent) | 80ms | 4K | $10/mo |
| RustDesk | ✅ (Tiled) | 120ms | 1080p | Free* |
| Splashtop | ✅ (Thumbnails) | 150ms | 4K | $99/yr |
Recommendation: 1. Parsec for lowest latency and independent screen control 2. Splashtop for compliance-ready financial use 3. RustDesk if you have IT admin resources
Bandwidth Optimization
1. Set Texas PC to hardwired Ethernet (not WiFi) 2. Use HEVC encoding where available (30% bandwidth savings) 3. Limit FPS to 30 (trading doesn't need 60FPS)
