I want to know how this 4k120hz monitor also does 540p480hz with the same panel

According to this site, the 4k 120hz monitor can also do 540p480hz. How?

From what I know, decreasing the resolution does not affect the refresh rate. The only way I could think of for it to work like this is to divide the screen into groups of pixels and having the pixels in the group take turns displaying the image, but in the photos this does not seem to be the case.

The resolution is probably more of a bandwidth constraint. Getting 480 images per second at 540p to the monitor probably requires a similar bandwidth to 120 images per second at 4K?

"" The Zisworks engineering sample uses an ultra-fast FPGA chip to achieve the ultra-high-Hz goodness. It works on an off-the-shelf 4K 120Hz LCD, by replacing the LCD panel’s motherboard. Zisworks also has DIY engineering modification kits for those with compatible LCD panels. ""

So that means you can get one of those mod kits and mod your 4k monitor to do 1080p120hz?

I supose so , but its a DIY thing, meaning YMMV

Yeah I always wondered why we don't have scaling like we did wit CRT so you could have todays monitor 4k@120Hz for example and option to switch to 1080p@240Hz would be neat.
