Owners of Freesync Monitors can enlarge Hz range with simple hack
One of the negative dependencies for AMDs FreeSync is that you are tied and limited towards the operational range in Hz the monitor is capable off. A new tool, let's call it driver mod allows you to change the parameters so you can enlarge the FreeSync range. Users in our forums report this to be working.
The hack was published last month already, yet we are seeing increased interest in it so here's a little guide. By all means this is experimental. Now the procedure is a tad technical, but you need to download the following tools:
Here's what you need to do step for step (screenshot courtesy of OC_Burner). First you extract the EDID infomation into a file:
Then EDID modification #1:
Then EDID modification #2:
Monitor.inf driver creation:
Adding newly created driver range info:
Deactivate Windows Driver signature:
Install monitor driver:
Enjoy the changed dynamic range ... We have seen users report framerates as low as 33 Hz supported.

Not rly. It is simple idea and author faced few obstacles with already known solution, so he did kindly include them.
I have modified writeable parts of FW in my monitor to actually get proper color of that otherwise good screen. One of reason I try to evade BenQ, as 'they had one job'...

I may go for AOC G2460PF since it should be FSync 30~160Hz, I wonder if I can get it to 180/200Hz
- it is only 1080p, but that allows for higher refresh rate
I saw some notebook screens successfully OCed to 180Hz without frame dropping.
