Can integrated graphics output HD video?

[Windows Central Question]

It's known that an integrated graphics card isn't suitable for high end gaming and a discrete graphics card is required. But what is required on a laptop that connects to a HD projector or HD screen, and plays HD video?

Will integrated graphics be suitable?
Is a laptop with discrete nvidia graphics required?
Were integrated graphics previously not suitable, but the new kaby lake systems are now suitable? For example, is the new Dell xps 13 (which only has in integrated graphics) suitable?
How does this change if the laptop needs to output 4K video to a 4K display?

I cannot comment on 4K video, but laptops with Intel Integrated Graphics from 2009 have been able to play 1080p video (from personal experience). Just make sure you have the latest drivers.

Got a 2014 laptop with integrated graphics, 1080p is no problem, no idea about 4K though.
