And yet LG's newest ultrawide is limited to 120Hz because of G-SYNC. If you want to go above 120Hz with G-SYNC you have to pay a lot of money and have a whacking great fan stuck in your screen.The main issue is ranges. There can be a 144Hz monitor that states "Freesync" but might only have a range of 48Hz-70Hz in which Freesync works. This is the main problem with Freesync. Check out this list of Freesync monitors and their ranges.

Quite an eye opener if you ask me.
Like so many have said, each tech has it's issues.
