Hi IGNACIO FONSECA HERNANDEZ,
We understand the frustration of juggling workflows on a single screen! The Surface Pro 12 (2025) can drive 3 external monitors in extended mode, but it requires specific hardware due to its 2x USB4/Thunderbolt 4 ports and GPU
The Surface Pro 12 (2025) supports driving three external monitors in extended mode, but it requires specific hardware due to its two USB4/Thunderbolt 4 ports and GPU limitations.
Here’s how to set it up reliably:
Option 1: Thunderbolt 4 Dock (Recommended)
Use a certified Thunderbolt 4 dock (e.g., Caldigit TS4 or OWC Thunderbolt Hub) with monitors supporting DisplayPort 1.4/HDMI 2.1. Connect the dock to the Surface via Thunderbolt 4, attach monitors to the dock’s ports, and extend the desktop in Windows Settings. Thunderbolt 4 supports dual 4K@60Hz and one 1080p@60Hz monitor via a single cable.
Option 2: Hybrid Setup (Dock + Direct Connect)
For mixed resolutions, connect two monitors via a Thunderbolt dock and the third directly to the second Thunderbolt port using a USB-C to HDMI adapter. Use Windows + P to extend the display.
Troubleshooting Tips:
Ensure Surface firmware and graphics drivers are updated. Use certified 8K cables and verify monitor HDCP 2.2 compliance. Test each Thunderbolt port individually.
Preventive Measures
Use Thunderbolt-certified cables, avoid HDMI splitters or uncertified USB-C hubs, and keep the Surface ventilated to prevent GPU throttling.
Note:
The Surface Pro 12 officially supports 2x 4K@60Hz + 1x 1080p@60Hz.
For 4K workflows, consider reducing to two monitors to avoid GPU strain.
