The stuttering and FPS drops on your laptop + external monitor setup are caused by the limited bandwidth of the DisplayPort 1.4 cable, which cannot handle the high refresh rate of the ROG Strix XG27UCS monitor at native 3840×2160 resolution. This is a common issue with high-refresh-rate monitors and can be mitigated by using an HDMI or USB-C connection instead.

⚠️ Common Causes

  2. Step 2: Connect the new cable to both the laptop and monitor
  3. Step 3: Update drivers and software to the latest versions

Method 2: Monitor Settings Adjustment

  1. Step 1: Adjust the monitor's refresh rate to a lower value (e.g., 144Hz or 120Hz)
  2. Step 2: Lower the monitor's resolution to reduce bandwidth requirements

Method 3: GPU Upgrade

  1. Step 1: Check if the laptop's RTX 5060 Laptop GPU is capable of handling the monitor's refresh rate and resolution
