U4025QW, iMST refresh rate
Hello,
Can someone shed light on whether the refresh rate (120Hz) remains the same or decreases if I use the iMST function to split the screen either 50:50 or 75:25 (80:20)? I am currently looking to purchase this monitor only if the frame rate remains at 120Hz while using the screen partition. I am considering replacing my U3425WE, which halves the frame rate to 60 when iMST is activated.
Thanks.

The U4025QW User's Guide page 78 calls iMST "Screen Partition (DP/TBT)". There is a setting for Screen Partition refresh rate 60Hz or 120Hz.
