From the beginning of having my laptop I thought the screen was dark. It's a Gigabyte P35 V6 with an i7-6700HQ processor and Intel HD Graphics 530.
Yesterday briefly the screen went black for a second, I heard the sound as if a device was unplugged from the laptop, and when it came back it was much brighter. As soon as I changed the brightness however, it went back to its original state - quite dim even at full brightness. I then updated the drivers, and right after the update the screen was much brighter at every setting. This time even changing it didn't make it go back to that dim state, I could adjust it down and then back up to the very bright setting. After a restart it's dim again however.
What's the issue here? I hope I explained it well enough, it's a bizarre issue and I'm thinking it's something to do with the registry as I played around with every setting in the 'Intel Graphics' options and it's not getting me anywhere.
