Refresh rate problem

Refresh rate problem

So I have a 2017 15 inch HP Spectre x360 which I hackintoshed and got almost everything working except sleep and a 60Hz refresh rateI can't adjust my refresh rate, it's eternally stuck to 40Hz.I tried using a hidpi patch but that didn't really help me

(P.S. it's the internal 4k panel and holding down the alt key doesn't help)
