Is there a way i can somehow remove these patterns? Also what is the name of this?

What are you talking about? 

The image looks pretty close to black …

Ah, there is a gradient … 

Could you please post a screenshot taken at View > 100% with the pertinent Panels (Layers, Channels, Options Bar, …) visible? 

Is the gradient created via a Gradient Layer, a Layer with a Layer Mask, …? 

If the gradient is one or more meaningful editable objects try changing the image to 16bit and, if necessary, blur further and/or add noise.

Also ive seen this on many places with mac users. How can you do thaty, that when you screenshot something the windows and graphics dont lose resolution when zoomed in?

So it is about the banding? 

If so blurring at 16bit seems the approach most likely to produce meaningful results to me. 

But you can also (or additionally) try to add noise. 

As for screenshots:

The screenshot I posted is a png, so the pixels will become noticable when zoomed in.
