[SOLVED] How can I get 4K at 60hertz in 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.

If your laptop does not have an HDMI 2.0 port and doesn't have any alternate means of connecting eg. MiniDisplayPort, DisplayPort, USB Type C with Thunderbolt, then you will be limited to 30Hz at 4K as HDMI 1.4 dsoes not have the bandwidth to run 4K at 60Hz. You could try to run 1440p at 60Hz, HDMI 1.4 theoretically has the bandwidth for that resolution and refresh rate. Other than that, unless the laptop has a compatible docking station with DisplayPort or HDMI 2.0 support that you could get, you're basically out of luck.

Ok guys I know 4k is not possible in 60 Hertz but what we can do by Custom resolution CVT-RV
Max- 1920x1080@120hz
2560x1440@70 hz
3456x1944@40hz
3072x1728@52hz(mine)
2944x1656@57hz
Those are for intel graphics try it now..

Right off the bat, HDMI 1.4 and HD530 graphics can support 2560x1440 @ 75Hz.... So something is amiss there.


I'm a little perplexed by your choices overall....
What is it you're looking to accomplish with this setup?
A 960M isn't going to be doing too much in terms of gaming at (or near) 4K and if it's video playback, you're not going to see content streamed in it's native resolution or refresh rate...

An interesting choice... but I can't think of a logical scenario to go this route.
