2. I noticed that increasing the VB also increased back porch V and total V lines. Will this affect my monitor in any way? Like its parts, its health, gaming experience (flickering, etc)?
3. Freesync is now disabled in AMD Software. Can this be fixed?

1. Increasing the vertical blanking gives the GPU more time between screen refreshes to retrain the memory when changing clock speeds. If the vertical blanking is too low, it won't have enough time to retrain the memory without corrupting the screen contents.
2. Increasing the blanking also increases the bandwidth used, but as long as it works, there shouldn't be a problem. The monitor might not be able to display the increased blanking correctly though.
3. I don't see why that would disable FreeSync.
