You guys are so fucking arrogant to think anyone with an issue must not know how to work a mouse to find Settings. If we hadn't already done all those things ourselves at some time in the past we would never have seen our 2d monitor work with our computer. In short, you're taking us through grade school when the problem is clearly an upper-classroom issue.
Absolutely none of this worked for me. Still can’t detect my tv no matter what and it was working literally just before the update. EDIT; turns out the update had disabled one of my integrated graphics cards and it was as simple as reactivating it though device manager.
