Device: Predator PHN16-71 NH.QLVEP.00A which is equipped with i9-13900hx and RTX 4070

Hello, all users of Acer, today I faced such a situation (I am sharing a gif.) It happened suddenly after turning on the laptop, but repeatedly, the last time I had it was about three months ago, and then after restarting the laptop it disappeared as if it had never happened. And here it is again... But after trying to switch from Optimus to Nvidia GP, these flickers also disappeared.

    You can download and reinstall the oem Acer Intel VGA drive version 31.0.101.4146 for the Predator PHN16-71 laptop, and clean install this driver as this should fix your screen flickering up completely, its not a hardware problem.

    I hope this helps! If this was useful, please hit 'Yes' or 'Like'! Thanks! 😊

    Thank you for your reply!Can you tell me more, please, which driver version do I need to choose with or without the UMA prefix? And I would also like to know which file needs to be run in the archive to reinstall the drivers, I apologize for my incompetence...

    Press the Windows key and the X key simultaneously, then click "Device Manager", click the arrow next to Display adapters, right-click on your GPU, and select Properties. Navigate to the Driver tab and click Update Driver. In the Update Drivers window that opens, select Browse my computer for drivers.

    In the Browse for drivers on your computer window, select the Browse... button, browse to the location where the drivers were downloaded to, and then select the OK button.

    In the Browse for drivers on your computer window, make sure the path to the drivers is correct, then select the Next button.
    Windows proceeds to install the drivers if it finds that the drivers are updated versions of the drivers. If updated drivers are already installed, the message The best drivers for your device are already installed is displayed.

    Select the Close button to close the Update Drivers window.

    Also, make sure that windows is uptodate. To update Windows 11, go to Settings > Windows Update and select "Check for updates". If updates are available, you can download and install them, potentially requiring a restart to apply the changes.

    Did you try to install both Intel and Nvidia graphics drivers?

    There may be several reasons for your desktop screen flickering:-

    Loose or damaged cable connection: A faulty cable connecting the screen to the motherboard may cause flickering.
    Outdated or incompatible drivers: If your computer’s display drivers are outdated or incompatible, it may lead to screen flickering issues.
    Faulty screen or hardware: A faulty screen or internal hardware component can also cause flickering.
    Overheating: Overheating the laptop can cause the screen flickering issue.

    Software issues: Some software or apps may cause some problems, leading to screen flickering.
    Incorrect refresh rate: An incorrect refresh rate setting may also result in a flickering screen issue.
    You can start by checking your HDMI, Display-Port, or USB-C cables. Ensure that the cables are securely connected to both the monitor and the laptop. Make sure that the cable is fully tightened and it doesn’t look
    or feel loose. This applies to all cable types, which can become loose for various reasons.

    Plug in your system to an external monitor to check if the issue reoccurs. If the problem does not occur on the external display, it may be due to a hardware issue with the laptop’s screen. Next is to make sure that the graphic card driver is update. Outdated drivers may cause incompatibility, leading to screen flickering problems. Regularly updating drivers ensures optimal performance and a flicker-free experience.

    Also to note overheating can cause hardware issues so, routinely check your laptop’s temperature to
    ensure it is not overheating. Make sure you clean any dust or debris from the vents and fans to improve airflow.
