ROG Zephyrus M16 (2022) - Integrated Display Not Detected PLS HELP

TeoDaOne
Level 7

My setup:

Laptop Model: ASUS M16 2022 GU603ZM

External Display Connection: HDMI

OS: Windows 11

Issue Summary:

The problem started when I was shutting down the laptop and closed the lid then immediately disconnected the external monitor. Then after a while when I turned on the laptop (without the external monitor) the laptop's internal display failed to turn on, despite the system seemingly running Windows normally. So I went back and connected the external display and the laptop was working fine except only on the external display and the internal display is undetected. The problem is that even the boot screen and the bios are on the external display, almost as if the internal display is non-existent. But, here comes the weird part: when I switch to "Ultimate mode" and restart everything goes back to normal and works as it should and the bios is on the correct screen.

Details on how it happened:

  • External display is connected (mine was through the HDMI).

  • Laptop is in Standard mode (NOT using the NVIDIA GPU exclusively)

  • Shut down the laptop from the Windows start menu.

  • While the laptop is shutting down close the lid and immediately after disconnect the external display

  • Disconnect all other peripherals (headphones, charger)

  • Power back on the laptop (after approximately 20min if that matters)

  • You got yourself a laptop that does not detect its own screen

Attempted Solutions:

  • Tried to do the reverse actions (maybe the lid had to open while connected to the external display); no effect.

  • Completely uninstalled and reinstalled Nvidia GPU drivers using DDU; no effect.

  • Completely uninstalled and reinstalled Intel GPU drivers using DDU; no effect.

  • Completely uninstalled and reinstalled Armory Crate; no effect.

  • Completely uninstalled and reinstalled System Control Interface; no effect.

  • Tried to use GHelper; no effect.

  • Did a Hardware reset / CMOS reset; no effect.

  • BIOS reset while on Intel GPU; no effect.

  • BIOS reset while on Nvidia GPU; no effect.

  • BIOS rollback; no effect.

Additional info:

  • The Intel GPU functions correctly when an external display is connected via USB-C, the Intel GPU is working.

  • No physical hardware issues with the laptop.

  • When using the Intel GPU and external display Device Manager shows the integrated display as hidden with "Code 45" (hardware device not connected).

  • When I installed GHelper (and with Intel GPU and external display) it says Internal screen off.

  • No BIOS setting is available to change the display although it seems that the Asus BIOS has very limited settings.

  • In the BIOS (with Intel GPU and external display) under the LCD label it says the resolution of the external display - probably thinks that is the default.

If any other info is needed please write. Any help is greatly appreciated!

Hi @TeoDaOne ,

Thank you for providing detailed information. Could you please record a video demonstrating your process and the issue you're experiencing? Additionally, could you provide the following information so we can further investigate the problem?

 

  • BIOS version:
  • Windows Build Version:
  • NVIDIA GPU driver version:
  • Intel GPU driver version:
  • Monitor brand/model:

 

You mentioned that the Intel GPU works properly when connecting an external display via USB-C. Could you share with us the GPU setting mode in Armory Crate? Have you tried resetting the system and testing if the issue improves? Thank you.

Hello, thank you for replying.

BIOS version: 311, but tried with 310 as well; no effect.
Windows Build Version: Windows 11 23H2
NVIDIA GPU driver version: 551.86 Studio driver / Tried with the Game Ready driver; no effect.
Intel GPU driver version: 31.0.101.3962
Monitor brand/model: DELL U2715H


The problem is exactly the same when I use the laptop in any of these Armory Crate settings: Eco, Standard, Optimized. Basically only when Ultimate mode/dGPU mode is activated it works properly.
If by resetting you mean complete reinstall of Windows - no I have not done that and I doubt it matters.
I did a Hardware reset / CMOS reset; no effect.

As I explained above the problem is even in the POST, when on Standard mode (or any of the above mentioned) the laptop display does not even start the backlight of the panel. Not even before it boots. Thats why I do not think it has to do anything with the windows install (maybe even gpu drivers) as windows has not even started loading yet and the problem is there. Basically the laptop does not see its integrated display. The boot screen + BIOS only display on the external monitor if there is one.

This is standard mode with the problem:

 

This is restarting back to ultimate mode:

Hi @TeoDaOne ,
Thank you for providing the information. Have you tried using the NVIDIA Graphic Driver Version V31.0.15.1640 verified by ASUS for testing?
You mentioned that when you close the laptop and immediately disconnect the external monitor, if the laptop display does not show during startup without any connected monitors, could you please record a video for us to further investigate?
If the display is connected via USB-C, and you close the laptop and immediately disconnect the external monitor, will the laptop screen display properly upon restarting? Thank you.

Hi, sorry for taking so long to reply. I tried the NVIDIA Graphic Driver Version V31.0.15.1640 after I first uninstalled the current one using DDU. The situaltion is exactly the same. As I mentioned the problem is even in the POST and BIOS.
Yes the laptop display does not show when not connected to any external monitors (that is what actually happened the first time the problem appeared details are above). Also as I said before the problem is only when NOT using Ultimate mode/dGPU mode. I tried what you suggested with immediately disconnecting the monitor closing the lid etc. I tried all kinds of combinations of actions/ports/modes to get the laptop display to show up - but nothing it is just as if its not there at all. As I mentioned the problem is even in the POST and BIOS.

Hi @TeoDaOne ,

Thank you for providing the video. Based on the display in the Device Manager shown in the video, it appears to be related to a hardware issue. 
We suggest you take the laptop to a local service center for further hardware diagnostics. We apologize for any inconvenience this may cause you.

Hi,
I am positive that it is not a hardware problem as all the hardware is working, just not at the same time :D. The laptop monitor is working, both GPUs are working, and all the ports are working. I am pretty sure it has to do something with the BIOS. Most likely there is a hidden setting that configures the displays. Considering how the problem happened, it is probably the combination of me shutting the laptop down and putting the lid down at the same time so it switches to the external monitor and I guess somehow it got stuck on only the external monitor.

 

Below is a video where a guy switches his laptop's BIOS to show on an external monitor only. I wonder if there is some shortcut like this for my model, as the same shortcut does not work on my laptop.

P.S. The last time I had to deal with Asus support for a hardware issue, it took one month and I could not use my laptop. Not doing that again, especially when I know the problem is not hardware-related.
