What is the Theoretical Maximum Refresh Rate of TFT LCD Displays?

[SwaziLande]

I just picked up a free ViewSonic VP720b today. It's 1280x1024 TFT AMLCD, so not the highest resolution, but I was hoping to modify, or all together replace, the mother board so that it can increase the refresh rate to something higher than 85Hz. Before anything I wanted to know if that was even possible.
    I know about IPS panels, but I don't know if the reason they can have such a high refresh rate is due to the technology in the display it's self or the display controller. if it is because of the display controller, I was thinking I could maybe custom build a mother board to make the display have a higher refresh rate. Probably overkill, but I thought it might be a fun project.
    The current Flat Panel Display Controller is and old Realtek RTD2363 which I couldn't even find a datasheet for. But I could find one for an RTD2525 which seemed like the later evolution of the 2363 ( https://cdn.datasheetspdf.com/pdf-down/R/T/D/RTD2525-Realtek.pdf ). I'm not sure if this helps but the display it's self has a 30 conductor FFC. Thanks for any input, or for telling me I'm chasing unicorns.

The response time depends on the technology of the display itself. Apparently IPS are not the fastest:
