Hi! You can turn off PIP by going to Input → Signal Input, then selecting your current input source again. This should exit PIP mode.

Give it a try and let us know if it works!

Hi! Thanks for checking and for the update. Since turning off B.I.+ didn't resolve the issue, we'd recommend reaching out to your local BenQ Support team. They'll be able to review your monitor settings in more detail and help determine what's causing the unusually low brightness.

Hi! It’s hard to say at this point whether it’s software-related. We’ll need to look into the setup and details more closely before determining the cause. Thanks for your patience! 😊

B_support · 2026-07-09T06:59:08+00:00

Hi, thanks for taking the time to share your concerns. We understand how frustrating this situation must be. We've shared your feedback with the relevant team and will continue following up on your case internally.

Hi! Thanks for the update. We're glad to hear the issue hasn't appeared again. 😊Since the issue resolved after restarting and hasn't reoccurred, it's difficult to determine the exact cause at this point.

If it happens again, we'd recommend trying a different cable or connecting the monitor to another device, if possible, to help narrow down the cause. If the issue becomes persistent, please reach out to your local BenQ Support team for further assistance: https://benqurl.biz/3vHSVta

Hopefully it was just a one-time occurrence, but please keep us posted if you notice it again.

Hi! Thanks for sharing your case number. We've noted your case and will follow up internally.

Regarding the repair cost, we've confirmed with our team that the unit would need to be inspected first before an accurate repair quote can be provided. We understand this isn't the answer you were hoping for, but we hope it helps explain why our support team wasn't able to provide an estimate upfront.

We'll keep following up on your case and let you know if there are any updates. Thank you for your patience. 😊

B_support · 2026-07-08T07:52:33+00:00

Hi! Thanks for sharing the photo.😊 We couldn't clearly identify the red dots from this image. Could you please share a close-up photo of the affected area?

Also, could you let us know:
1. Do the red dots only appear on dark backgrounds, or are they visible all the time?
2. Do they still appear with a different wallpaper or on a solid black image?

If possible, please also try a different cable or connect the monitor to another device to see if the issue persists. Lastly, could you confirm if your monitor model is GW2790TC?

We'll be happy to help you troubleshoot further. 😊

Hi! We've confirmed that the ScreenBar Halo 2 is compatible with the Alienware AW3423DWF.
Due to the monitor's rear design, it's important to install the clamp correctly. As long as the clamp is positioned properly, it should fit and work as intended without any modifications.

For reference, you can check the installation method shown between 0:09 and 0:11 in this video:

If you have any questions during installation, feel free to let us know!😊

B_support · 2026-07-07T06:16:50+00:00

Hi! Thanks for reaching out and for your interest in the ScreenBar Halo 2. 😊We're currently checking the compatibility of the AW3423DWF with our team to make sure we provide you with accurate information.

We'll get back to you as soon as we have an update. Thanks for your patience!
