3,840 Hz refresh rate
Is that an American or European comma?
Maybe they mean horizontal scan rate?
American according to their spec web site:
A comment from a crosspost ( [email protected]) suggests it as the PWM rate of the LEDs
Which on a very... Marketing level could be described as refresh rate... I assume??
That would make way more sense from the pure figure perspective, thanks!
Did some investigating on that refresh rate number, it looks like the LED panels use something called Scrambled Pulse Width Modulation (S-PWM). From the little I can understand, it just seems to be a method of splitting and offsetting the PWM signal.
It's unclear to me if that means that a single pixel could be updated 3,840 times in a second or if the entire display collectively updates that much.
Playing with some math, if you had 4 sub-pixel LEDs updating at 120hz and separated into 8 sections across the entire panel that was each offset in time by some fraction, you could say there were 3,840 updates to the panel across a second. That would be quite the bastardization of the term "refresh rate", but I could see that being the case.

That's not really what people have in mind when referring to "refresh rate".😆
The refresh rate in the product spec page has to be an error. 3,840 Hz?
European comma, probably
Somehow I'm still sceptical. How would they achieve it and why would anybody need it?
Oh I didn't try to imply that it's true just that the number is what the producer claims and not a comma mix-up.
In another thread someone said that they put the LED pwm as refresh rate which sounds both reasonable to me and something a marketing department could come up with.
