Laptop Model: Acer Predator Helios 300 PH315-54-77D4
CPU: Intel Core i7-11800H
GPU: Nvidia Geforce RTX 3070 Laptop GPU
RAM: 32GB DDR4
OS: Windows 10 64-bit
I've encountered a problem with Intel Graphics drivers after installing a new LCD for my laptop.
The LCD of my laptop was broken, so I got myself a new one and replaced it. Problem is that the new display did not work properly (photo attached). The only way to make the display work properly is by uninstalling all Intel Graphics drivers. However, without Intel drivers Windows won't use the RTX 3070 for more demanding tasks, like gaming. Is there anyway to fix this?
Extra info: The LCD that was previously installed was NE156FHM-NZ3 V8.1, while the replacement LCD was NE156FHM-NZ1.

Hello joncat14,
Thank you for posting in Intel Communities.
Please note that this is an OEM device. I will try to assist you with general troubleshooting steps however, if the issue still persists, you will have to contact the Original Equipment Manufacturer of your device. Your device manufacturer may have altered features, incorporated customizations, or made other changes to some components for better compatibility with your system.
To get a better understanding of the issue and be able to provide an effective recommendation, please provide the missing key information here:
1) Current driver version installed.
2) Other graphics driver version installed that has the issue.
3) How did you installed the previous drivers? (Manually, using driver updater tool, etc.) Share the driver link if possible.
4) Driver details after "uninstalling the Intel Graphics drivers". Please take a screenshot of the device manager (driver properties tab).
5) Please confirm if this is the actual laptop you have: https://www.acer.com/gb-en/predator/laptops/helios/helios-300/pdp/NH.QC1EK.004
I will wait for your reply.
Best regards,

I think I've figured out why the display doesn't work.
In the GPU specifications for the Intel Core i7-11800H processor, the Graphics Output for the integrated graphics is eDP 1.4b, while the new LCD that I've purchased and installed has a signal interface of eDP 1.3. While Embedded DisplayPort is cross-compatible with different versions of it (at least from what I've read), the Graphics Output seems to not be compatible with an earlier version of eDP, only with version 1.4. This is also supported by the fact my previous display had a signal interface of eDP 1.4, and it worked perfectly fine with Intel Graphics drivers.
As for the reason why the RTX3070 doesn't work, it's because of how Nvidia Optimus works, and because the LCD is connected to the Intel display adapter, I cannot get the RTX GPU to work with the integrated display. However, I have found a workaround by using an external monitor and connecting it to the laptop to essentially kick start the RTX3070.
Of course, this is just the conclusion I came to after doing some digging online, so I will provide the information you request in the case my conclusion isn't correct and there is a possible software solution to this.
1.Current driver version installed: 30.0.101.1273
2. Other graphics driver versions I've tried installing: 32.0.101.6449/32.0.101.101.6256 and 32.0.101.5972 (both WHQL Certified, the same problem with the display not working properly occurred)
3. The current driver version was installed automatically by Windows, the other versions I've installed using the downloadable installers available on the Intel website (https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html)
4. Screenshot attached below
5. Yes, that is indeed the laptop I have.

Hello joncat14,
Good day!
I hope to get the additional details below:
1) Was the replacement LCD model recommended by your system manufacturer (making sure that it would work normally with this device)?
2) Have you tried installing the latest graphics drivers from the OEM download page? (Their drivers may appear older versions, but it is customized and should work fine on your system device. If not yet tried, you may check from this link below (just input your system serial number, or SNID or product number).
