Hey folks! Just bought my Dell U2725QE and i'm with some doubts about the HDR. 

I've activated on mine, but i think that the colors pop's on a very good way. The white is more bright, the shadows have more constrast. Didn't noticed anything "weird" at any color or any other circustances. 

But researching online, some people say to don't use HDR because it will only work with HDR media and other stuff like that, so I'm in doubt. 

On the user manual, I've found anything about the HDR or how it works.

I'm using a macbookpro, and i'm trying to make the dell screen looks closer to the mac screen. Even if I activate HDR inside the monitor, on mac settings there's nothing about HDR to turn on. 

So, what does this HDR do? Should I keep it on all the time?
