How to get 4K @60hertz from HDMI 1.4?

Hello everyone,

I have Lenovo Y700 laptop. It has Intel i7 core (Intel HD graphics 530) with Nvidia GTX 960M 4GB. Ram 16GB and has a SSD and HDD.​ Maybe the HDMI out version is 1.4 and my laptop has not any display port.

​Recently I bought a Acer 4K monitor (KG281K) it supports 4K at 60 Hertz. Monitor input to HDMI port 2.0 version and one display port may be 1.2 version.​

First I didn't know about the HDMI versions like what is HDMI 1.4 and what is HDMI 2.0 so i bought it blindly​.

I had one HDMI 1.4 cable, I thought this will work but it only gives 4K at 30 Hertz, so I looked internet and order HDMI 2.0 cable from Amazon in the cable review section page they have said this cable is capable of 4K at 60 Hertz.​

Then I see it's not giving 60 hertz at 4K resolution​, its giving only 30 Hertz. If I do 1080p on the monitor so it runs smoothly in 60 Hertz.

After all the research I think maybe my laptop has not that HDMI 2.0 out version maybe it is a HDMI 1.4 so it cannot deliver the bandwidth is needed for 60hertz.

I really need your help please help me to get 60hertz at 4K resolution

Thank you.​

According to the Lenovo support site - which you (hint, hint) could have visited yourself - the HDMI port only supports HDMI 1.4. You are stuck with 4K@30Hz.

 

Sorry,

Sorry, this is really impossible. Lenovo Y700 does not have HDMI 2.0 version

As @n.scott.pearson​ and @tuanhung, Lenovo Y700 doesn't seem to support HDMI 2.0, but I have just found a solution for you in Lenovo forums. You can try: https://forums.lenovo.com/t5/Displays-Options-and-Accessories/Lenovo-Y700-15ISK-and-4K-60Hz/td-p/352...
