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.
