Since I am back taking pictures I need a good post processing hardware. Most important is display, I can live with a medium performance processor.

I would prefer a tablet or Laptop since I do most of my work in bed, a huge screen wouldn't be that practical.

What screens/laptops do you suggest what are the specs I should look for ? Do I need a 4k screen?

Would it be practical working on laptop and seeing the work on a mirrored screen (Miracast technology)this way I keep my laptop and use a TV Instead of PC screen

 

4k/retina screens aren't well supported on Windows yet.

Seems as if something like the 13" Macbook Pro may be the right thing for you.
