Custom Resolution Utility (CRU)

[4700mq]

my laptop is msi gf65 9sd

gtx1660ti
16 gb ram
120hz panel with 15.6 inches
and ssd 512
its impossibile to set a custom or any other hertz to this laptop or to other 14 other laptops which has intel gpu and nivida gpu. this app is broken or dead? or its just a luck i cant make any hertz? the alt methood does not work, it wont make any result, the normal way ( using the exe cru app ) then restart wont add values to the hz poll in the settings.

i can not change the refresh rate what so ever i do.

i tried this steps but not work:

on windows 8.1 installed the latest driver and tried to change from control panel of intel but it show that it exceeds maximum bandwith i tried on all resoultion i tried to underclock the refresh rate to 58 or 59 not worked i tried everything it can not add any new values.
i tried CRU added new values and clicked on restart 64 and restarted my laptop but the values are not in the control panel or not in the contorl panel of windows nor in the list all modes option.
i tried to overclock the other montiors on the CRU (the not active monitors) same thing. i tried on older versions of the driver same thing. i tried new apps same thing.

and for windows 10 i tried all the steps above but the same thing.

and my gt730M has no refresh rate or custom resoltions option it has only 2 options.
