Hi,
Have you checked that you have the latest graphics adapter drivers applicable to your OS and your graphics adapter installed?
I say this as there are updated drivers for the Intel graphics adapter dated 22/11/2016 if you have Win 10 64 bit or Win 8.1 64 bit installed which according to the details Fixes: - Intel bug issue fixed. Enhancements: - Improved stability of 4K video playback. There is no change to the nVidia graphics adapter driver.
Here is a link to the driver download page for your laptop and Win 10 64 bit OS. Scroll down to video and click to expand.
