How can I make Variable Refresh Rate (Adaptive-Sync / FreeSync Premium / G-Sync Compatible) work on my monitor?
Second, check if your monitor features the VRR function.
Our models feature with VRR function below:
XL2730Z, XL2540, XL2546S, XL2731, XL2740, XL2746S, XL2540K, XL2540KE, XL2546K, XL2731K, XL2746K, XL2566K, XL2546X.
On the monitor, please turn off DyAc/DyAc+ (if your monitor has that feature) through the monitor menu, since DyAc/DyAc+ is not compatible with variable fresh rate technology.
Then turn on the Adaptive-Sync/FreeSync Premium function through the monitor menu.
