4440Hz Display?

Viewsonic are advertising a 108" LED Display with a "Refresh Rate: up to 4440Hz". How is that possible? The specs do mention that the "Vertical Scan Rate: 56-85Hz".

 

But when I'm looking up the definition of vertical scan rate, it's telling me that it is synonymous with refresh rate. So, what's with the discrepancy? Is it 4440Hz, or 56-85Hz?

Its meant for Airports and stuff, but 4440Hz is possible, but I think they mistyped it

it isnt?

the highest refresh rates we have is like 500hz on 1080p like 30in monitors.

Its harder top go faster as you get faster and as you get bigger

I could use some help with this!

that depends on how the signal is sent and updated and what the "pixels" are, it can be a dot matrix display which individually addresses each pixel allowing way over 4000hz into the 100khz refresh rate range when forward voltage driving the "pixels" (which are actually leds on pwm signalling)

 

based on the size vs the resolution and the "removable led panels" it's likely a dot matrix where each pixel is like 1/8" or 1/16" diameter leds

The best gaming PC is the PC you like to game on, how you like to game on it

Looking at some of the documents linked at the bottom the screen seems to be made up of small individual modules? That 4440 Hz is probably just the "combined" refresh rate of how many the controller or something can ultimately handle in that case. If so, they're probably just doing monitor marketing like saying three 60 Hz screens are "180 Hz" refresh rate from your GPU.

Yeah interesting, maybe some form of PWM or touch sampling rate though.
