      Sounds like you have the wrong device drivers for this computer. Check with Acer on the proper video device driver for your chipset and computer model.

      Every video chipset offers a basic compatibility to allow for generic drivers to be used for low resolution like VGA (640*480) resolution. This is why you are working ok in SAFE MODE.

      For higher resolution and higher refresh rates, special device drivers are required. Do not assume the video chipset drivers from other source will work on the box. They may have been modified specifically for this laptop model. Only use the video drivers from the manufacturer of the laptop to remain fully compatible.

        Drivers i use worked fine before the incident.

        acer driver - same
        HDMI - same.

        Well it should work fine with Display port, since it goes direct to NVIDIA.
