ASUS TUF Gaming B16 FX607 NVIDIA RTX 4070 Black Screen on Boot Fix

The ASUS TUF Gaming B16 FX607 is powered by the NVIDIA GeForce RTX 4070 GPU. Some users encounter a black screen when booting or waking from sleep — the laptop powers on (fans spin, keyboard lights up) but the display remains dark.

This guide covers the most effective fixes for the black screen on boot issue on the ASUS TUF Gaming B16 FX607.

Common Causes of Black Screen on Boot

• Corrupt or incompatible NVIDIA GPU driver
• Incorrect display output selected (dGPU vs iGPU)
• Armory Crate or GPU mode switch requiring a restart to take effect
• Overclocking or memory XMP causing instability at boot
• Faulty display cable or panel issue

Step-by-Step Fixes

Fix 1: Force a Display Output

If the laptop is outputting video to an external port instead of the built-in display, the screen will appear black:

1. While the screen is black, press Win + P and then press the right arrow key twice followed by Enter to cycle display modes.
2. Alternatively, try connecting an external HDMI monitor to check if video is being output there instead.

Fix 2: Clean Install the NVIDIA Driver

A corrupted NVIDIA driver is one of the most common causes of black screens on gaming laptops:

1. Boot into Safe Mode by holding Shift and clicking Restart, then selecting Troubleshoot, Advanced Options, Startup Settings.
2. In Safe Mode, download and run DDU (Display Driver Uninstaller) to fully remove the NVIDIA driver.
3. Restart normally and download the latest NVIDIA driver for the RTX 4070 from the NVIDIA website.
4. Install without restarting, then restart once the installation is complete.

Fix 3: Switch GPU Mode in BIOS or Armory Crate

The TUF Gaming B16 supports switching between Ultimate (dGPU only) and Standard (Optimus) mode. Switching modes sometimes requires a restart and can cause a temporary black screen. If the laptop was left mid-switch:

1. Power off completely (hold the power button for 10 seconds).
2. Restart and press F2 to enter BIOS.
3. Navigate to Advanced > Graphics Mode and confirm the setting is not set to an invalid state.
4. Save and exit.

“Booting into Safe Mode and doing a clean NVIDIA driver install via DDU resolved the black screen completely. The issue started after a driver update through GeForce Experience.”

Fix 4: Reset BIOS to Default

Incorrect BIOS settings or failed overclocking can cause boot display issues:

1. Enter BIOS by pressing F2 at the ASUS logo.
2. Press F9 to load default settings.
3. Press F10 to save and exit.
4. The laptop will restart with factory BIOS settings.

Fix 5: Test with an External Monitor

Connect an HDMI cable to an external monitor while the laptop is running. If the external display works but the internal screen remains black, the issue is specific to the laptop panel or its cable — contact ASUS support for a hardware inspection.
