Why not just swap the panel in the laptop for a 120hz panel? I did that on my Helios 300 (the early version that had quite the poor screen). It took a little research to find a 120hz panel with the eDP 30 pin connection and I had a brighter, faster, more color accurate screen that was a joy to game on.
Plus the installation was pretty easy. Take the bezel off, 4 screws out, lay the screen down to access the back, remove cable, move new screen into place, attach cable, 4 screws in, power on laptop to test, remove factory screen protection, and reinstall bezel. Then get the Custom Resolution Utility from Toasty X to configure the stupid Intel graphics and you are good to go.
I was done in like a half an hour and have been in love with the picture ever since.
Unless you just wanted the bigger screen... because this won't help that.
