How to increase FreeSync limits above 240Hz?

Post by F1zus » 16 Jan 2026, 20:27

I got a Chinese 1920x1080@600Hz monitor.
But FreeSync wasn't working by default, even though it's what the manufacturer claims. I added the FreeSync Range option and specified 48-240. I can't specify 360/540/600 because they're red and aren't applied. Now FreeSync works at up to 240Hz. How can I increase the FreeSync frequency to 500 or 600Hz?
The monitor is connected via DP 2.1, and the graphics card is an AMD RX 9070XT.

I believe the upper limit of the freesync range isn't taken into account to begin with, at least on nvidia. Only the low-end is.

Consider DSC also creates some complications in the ability to create custom resolutions & custom refresh rate ranges.
