Can my computer get more hertz if i turn down resolution

[Caspernr]

Im asking this question because i have been thinking about buying a monitor, so i can more desktop space for gaming and school work.

But the issue is i have two computers, one for gaming and one for school

School computer specifications:
MacBook Pro (Retina, 13”, primo 2015)
Minidisplayport

Gaming Pc (Asus n53S):
CPU:
Intel Core i7 2670QM / 2.2 GHz
Cores: 4 / Quad-Core
RAM:
8 GB (2 x 4 GB) DDR3 SDRAM
Harddisk:
500 GB HDD
Screen:
15.6" Widescreen,
Resolution: 1920 x 1080 (Full HD)
Ghraphic card:
NVIDIA GeForce GT 630M - 2 GB DDR3 SDRAM
Connectors
HDMI

I have read online that it is possible for my macbook pro 2015 model, to run 4k display @60 Hertz "http://www.digitaltrends.com/computing/the-new-apple-macbook-pro-13-inch-is-finally-fully-4k-capable/

But i know my Gaming PC will not be able to play games at 4K, but if i turned down the resolution on the monitor when using it for gaming, will I then get more Hertz?

More hertz? In short no you may get more fpp. Hertz are to do with your monitor and hertz are set in stone unless you have a monitor where you can change the refresh rate, most monitors will have a 60hz refresh rate but some higher end monitors will have 144hz refresh rate, this means that your monitor will not be any better if the fps you have in game goes over the refresh rate of your monitor, so if you have say 120fps in a game and you only have a 60hz monitor you will only see 60 fps.
