Custom Resolution Utility (CRU)

FreeSync is like increasing the vertical blanking in CRU without changing the pixel clock. It always sends at the same rate as 75 Hz and varies the blanking to delay the next refresh. The monitor probably has a limit for how long the blanking period can be. Static 37 Hz doesn't have a delay beyond normal blanking. It just sends at a slower rate.

Appreciate the very clear explanation.
Your explanation made me thinking: what if i minimize the standard blanking so that the freesync induced extra blanking JUST falls into the range of my monitor.

And it worked! It took a lot of tweaking with basically all settings (back/front porch and sync both horizontally and vertically) and now my monitor displays 37-75hz perfectly and i have full LFC now! I only have very rare tearing if the FPS is between 37-38 (i suspect actually it's limited to a decimal range) but that is hardly noticably in practice.

So thanks a lot for your help Toasty!

For others having my monitor (LG 29UM59-P), please find below the settings that worked for me.
