Recently purchased Acer Nitro 34” Class WQHD Curved Gaming Monitor(ED340CU).

  1. Where do I get the display drivers for this monitor. Even Acer website doesn't seems to have any.
  2. Max resolution supported by this monitor as shown in Win11 is 2560x1080. But specifications say 3440 x 1440 Resolution is supported. Why am I getting only 2560x1080.

Please let me know.

    1. Monitor drivers are not display drivers, typically small (2-3 MB), help the operating system recognize the monitor and its capabilities. However, they are often not essential, as Windows can automatically manage basic functionality through generic drivers. Running Windows Update usually suffices to ensure proper operation without needing specific drivers. Acer website may have driver for this model but they are not display driver. Reinstalling gpu driver while monitor is connected helps to recognize new monitor. So make sure you did this already.
    2. Display drivers are GPU driver. What GPU do you have? Have to make sure that your GPU support 3440x1440 resolution.

    1. Check Graphics Driver
      Driver Update: It's possible that the Intel Iris Xe driver installed on your laptop is either outdated or misconfigured. Make sure you have the latest graphics driver directly from Intel's website, rather than relying solely on the default drivers from Windows Update.
      You can download the latest Intel Iris Xe Graphics driver here.
      After updating, restart the system and check the resolution options again.
    2. Check Display Settings
      Go to Settings > System > Display, and under the section for your external monitor, see if 3440x1440 appears as an available option. If it doesn't, click on Advanced display settings to see more resolution options.
      Make sure the display scaling is set appropriately for the external monitor under Settings > System > Display > Scale and layout.
    3. Use the Correct Output Port
      Output Port: Verify which port you're using to connect the external monitor. Different ports have different bandwidth limitations, which could affect the resolution.
      HDMI: If you're using HDMI, make sure the port and cable support HDMI 2.0 or higher. HDMI 1.4 can be limited to 1920x1080 at 60Hz on some laptops.
      USB-C/DisplayPort: If possible, try using a USB-C or DisplayPort connection for better support of higher resolutions like 3440x1440.
    4. Check Intel Graphics Control Panel
      Right-click on the desktop and open the Intel Graphics Command Center or Intel Graphics Control Panel. Navigate to the Display settings and check if you can manually set the resolution to 3440x1440. Sometimes, the resolution options in Windows settings may be limited, but the Intel panel allows more flexibility.
    5. External Monitor Settings
      Check the Monitor Settings: Make sure the external monitor itself is set to allow 3440x1440 resolution. Sometimes the monitor may default to a lower resolution, and you can manually change it in the monitor’s settings menu.
    6. Cable Quality
      If you’re using an HDMI cable or adapter, ensure that the cable is high quality and supports higher bandwidths necessary for 3440x1440. A low-quality or older HDMI cable may only support 1080p resolution.
    7. Check Laptop Specifications
      Internal Limitation: The issue may be due to limitations of the laptop itself. While Intel Iris Xe Graphics is technically capable of supporting resolutions beyond 1920x1080, it's important to ensure the specific model you have can handle an ultrawide resolution of 3440x1440. If the HDMI port on your laptop only supports HDMI 1.4, for example, it would cap at 1920x1080.
      You can also check HP's official specifications for your laptop model to confirm the maximum supported resolution on external displays.

    Conclusion
    The situation you're describing seems likely to be a driver or port limitation, given that your previous laptop worked fine with the same external monitor. Try updating the drivers, verifying the port type, and experimenting with the Intel Graphics Control Panel. If none of these steps resolve the issue, it's possible that the laptop's hardware, like the HDMI port

    Ensure your Intel N97 drivers are up-to-date. You can do this by visiting Intel's website. First I recommend to uninstall current GPU driver using DDU Uninstaller

    You don't need drivers, the monitor is plug and play, so Windows will see it and set the correct resolution for you.
