x230t specs for UHD/4k display on external monitor

I was wondering if this model is capable of displaying UHD/4k on the external monitor.

To my knowledge this computer has Intel HD graphics 4000 but I don't know if it can handle UHD.

Furthermore, I would like to ask what version the display port is since ver 1.2 is required to view UHD at 60hz.

Let me know if there are any other things to consider to solve this problem.

Thanks

Re: x230t specs for UHD/4k display on external monitor

you can't view the UHD at 60 hz, only at 30 hz.

This is an old list that i generated in regards to the Intel HD 3000 and 4000 compatibility with the UHD resolution.

Re: x230t specs for UHD/4k display on external monitor

Thanks Jin,

 

It's just that when I connect my x230t via displayport 1.2 cable to my uhd(4k) monitor, the best resolution I get is just a 1080p (full hd). I checked my laptop display settings and made sure to use my 4k monitor as an external monitor showing only and not as a dual(duplicate or expansion) display with the laptop.

 

I know that even if the display port was 1.1, I could still manage a 4k @30hz, but I am surprised to see that I am not getting even a qhd resolution.

 

Am I missing something?
