Thank you very much for contacting the Intel® Communities Team.
I understand you are facing some issues with your Acer Predator XB241H Monitor which losses signal while playing some games with your GIGABYTE® P35W V3 Laptop. I will be more than glad to assist you further.
In this case, I would like to double check which is the video controller in charge of the display on your laptop when the DisplayPort™ is connected. Please go to the Windows * Device Manager and double-click on Display adapters. Verify which controller is listed in the drop-down: the Intel® HD Graphics, the NVIDIA® controller or both of them. Please let me know in your next post.
Additionally, I would like to get a Dxdiag report, in order to provide this, please follow these steps:
1. On the keyboard, press WinLogo key + R.
2. In the Run box please type dxdiag and hit Enter.
3. Click on Save All Information (save it to your desktop).
4. To attach a file, you must click the “Attach” option on the bottom right-hand corner of the response box.
Furthermore, can you download and install your monitor's drivers? Please let me know which are the results of this step.
