In this case, please bear in mind that your best support is DELL as they are more familiar with your system and how all the features interact with each other.
Intel sells products to various OEM’s (Original Equipment Manufacturers), who then integrate them, with other system components (power supplies, disk drives, add in cards, software, etc). These systems may be customized to the OEM’s specifications.
However, you can try installing the latest graphics manually; you can download the latest driver here:
Please uninstall the driver you have installed, you can check Uninstalling the Intel® Graphics Driver and check how to Manually Install an Intel® Graphics Driver in Windows® 10 and Windows 8*/8.1*
If this does not work, most likely you have a defective system and it needs to be replaced, if the unit is still under warranty I suggest you to contact the place of purchase or to contact DELL to request a replacement.
