I do have HDMI 2.0 USB Cable,that's not an issue,i need to overclock the processor,but i can't find any way to do that.CRU ain't working for me.You should be working with the nvidia control panel and the MX110 graphics adapter.
Past that, I do not know what refresh rate is possible with your monitor and a hdmi cable.
I suspect you can do better. 60hs @4k will usually need displayport or hdmi 2.0
allright,i tried asking because i actually succeeded overclocking my laptop's display with CRU from 60Hz to 85Hz,and i thought there's hope for me to do that to the HDMI output as well.What you want to do, and what you can do, do not always coincide.
Generally speaking overclocking on a laptop is a bad idea, the tolerances of the build do not usually lend itself to overclocking.
Factor that in with what you want to do with the graphics and it does not seem that your expectations are realistic.
Best bet, just my 2 cents, you need a better laptop or desktop.
