4k on laptops?

[Seemly]

I bought a Lenovo Y50 (4k version) and it's coming on it's way. However, some people tell me it's not good, and that it decreases performance. Why?

There is nothing you can do about the 48Hz refresh rate. Below is a recent thread about it in Lenovo's forums; started on 7/7/2015.

A Lenovo Administrator posted a reply with a link to a previous rely in another thread back in Oct 2014. Basically, the Y50 has been designed to use the UHD screen at 48Hz, but they have been looking into increasing it to 60Hz without success.

I will just wait, i spoke with the support and they promised to look for a fix
