T450s no 4k 60hz support over Mini-Display Port 1.2

Hi,

 

I've got a T450s with Intel HD Graphics and my 4k Monitor is not working with 60hz.

 

I only get 2560x1440 with 60hz.

 

What I tried:

- New cable

- Latest drivers

- New Bios Version

 

Does anyone have the same problems?

 

Thanks

 

Mathias

Re: T450s no 4k 60hz support over Mini-Display Port 1.2

Is there somebody to get 4k with 60hz over mini-display port? with the following hardware specs:

- using a Lenovo T450s

- no dedicated GPU (nvidia)

- with onboard graphics (Intel HD)

- 4k Monitor with display port

- using mini-display port on lenovo notebook

- no docking station

 

If yes, please tell me

- what monitor are you using?

- which graphics drivers are you using?

- which bios version do you use?

- what kind of cable are you using?

- which specific settings do you use?

- are you using windows 7 or 8?

 

Thanks,

Mathias

Still nothing? Is there a BIOS update or software update coming?

- what monitor are you using? Samsung U28590D

- which bios version do you use? 1.17

- what kind of cable are you using? mini-dp to DP (some no name brand)

 

@its probably not worth answering the following questions since I'm using Linux but before I wiped Windows from my T450s, I used the Lenovo updater and upgraded everything (BIOS, graphics drivers, etc) and I could get it to run 4K @ 60hz.

- which graphics drivers are you using? 

- which specific settings do you use?

- are you using windows 7 or 8?
