How to turn a Lenovo Legion Go 2 into a 1440p gaming PC with an RTX 5060 eGPU

# Project summary This guide covers the steps and practical considerations shown in a video walkthrough that converts a Lenovo Legion Go 2 handheld into a 1440p‑capable gaming PC by adding an external RTX 5060 GPU, a JSOX docking station, and a TCL mini‑LED TV. The setup targets smooth visual quality and reliable performance for modern games while addressing common connection and stability issues.

# What you'll need

• Lenovo Legion Go 2 handheld.
• External GPU with an RTX 5060.
• JSOX docking station (provides USB, HDMI and USB‑C connectivity and a controller holder).
• TCL mini‑LED TV (used for sharper contrast, higher brightness and VRR/G‑Sync compatibility).
• High‑quality USB‑C / Thunderbolt cables.
• Detachable controllers and optional touchpad (Legion Go 2 accessories).

# Basic setup steps

1. 1Dock the RTX 5060 eGPU into the JSOX enclosure and connect the enclosure to the JSOX docking station according to the manufacturer instructions.
2. 2Connect the Legion Go 2 to the JSOX docking station using a high‑quality USB‑C/Thunderbolt cable. Pay attention to the Legion Go 2's USB‑C port placement to avoid stress on the cable or accidental disconnection.
3. 3Connect the TCL mini‑LED TV to the docking station via HDMI or the best available video output. Enable VRR/G‑Sync on the TV if supported.
4. 4Attach the Legion Go 2's detachable controllers or use the touchpad for desktop navigation. Use the docking station's controller holder to keep peripherals organized.
5. 5Update GPU drivers and the Legion Go 2 system software before first use.

# Performance tuning and settings

• Resolution choice: 1440p is recommended. The docking station caps refresh rate at 120 Hz, so 1440p gives the best balance of detail and frame rate for the RTX 5060 in this configuration.
• Upscaling: Enable DLSS where available to improve frame rates while preserving visual fidelity. Use frame generation to smooth motion in fast titles when supported.
• VRR/G‑Sync: Activate VRR or G‑Sync on the TCL TV to reduce screen tearing and stutter during variable frame rates.
• Games tested: The setup is demonstrated handling demanding titles such as Forza Horizon 6 and Assassin's Creed Black Flag with improved performance when upscaling and frame generation are used.

# Practical issues and troubleshooting

• Ventilation: External GPU heat management is critical. Ensure the eGPU enclosure has clear airflow and avoid bottling the unit in tight spaces.
• Docking limits: Note the JSOX docking station has a refresh cap (120 Hz). That influences which resolutions and refresh rates you can use effectively.
• Drivers and updates: Keep GPU drivers and any docking firmware up to date to avoid compatibility and stability problems.

# Who this setup is for This configuration suits someone who owns a Legion Go 2 and wants portable handheld functionality plus the option to play modern PC games at higher resolutions on a TV or docked display. It trades compactness for graphics headroom and requires attention to cabling and cooling to stay stable.
