Utöka Freesync spannet (drivarmodd)

Hello,

one week ago i find out how to modify my monitor driver for a custom FreeSync range. It begann with my Samsung U24E850R and i checked whats the different between "FreeSync Standard-Mode" and "FreeSync Ultimate-Mode" available by the OSD-Menue. After a comparison of the EDID-Data i find out, it's yust a single byte whats control the FreeSync refresh rate range. And yes it's possible to change this byte to get a lower FreeSync minimum refresh rate. I running this monitor with a range new range of 32hz - 60hz instead of the official 40hz-60hz. I am not alone, some other users have successfully modify his monitors.:

ASUS MG279Q (default 35hz-90hz) down to 31hz, #1
LG 27MU67-B (default 40hz-60hz) down to 33hz, #1, #2
LG 29UM67-P (default 48hz-75hz) down to 32hz, #1
LG 34UM67-P (default 48hz-75hz) down to 40hz?, #1
Samsung U24E850R (default 40hz-60hz) down to 32hz, #1

Beware, if the minimum range to low your got massive flickery screen artifacts. On my Samsung 32hz works perfect, one hz lower (31hz) results instantly in screen artifacts.
