Why 144hz?

[Skipple]

My question is what is special about 144? 120 is a multiple of 60 so that makes sense to me.

 

But 144?

 

144/8= 18?

But 60 isn't a multiple of 8.. 

 

Is 12 a special number for display properties?

 

I'm curious.

I believe this has actually been answered here before.  If i recall, it has something to do with the max output of DVI at a certain resolution (probably 1080p).  That explanation would kind of make the "standard" antiquated at this point, I suppose.

because 144 / 6 = 24

Pretty interesting that 144hz ended up being so common for a while. It seems like a 120hz monitor is best for systems without variable refresh:

 

120 / 5 = 24

120 / 4 = 30

120 / 2 = 60

 

Of course, variable refresh does take this concern out of the equation.

I don't think the numbers are predetermine.

Maybe it got something to do with electronic waves.

Because before 60hz, you have 50hz (which is the default frequency of AC line).

After that you have 75 and then 100, 120, 144 and so on.

variable refresh isn't an issue, monitors can change their frame rate, just not on the fly, you might notice older monitors going black for a sec when you start a video, that's the monitor changing the refresh rate.

12 isn't, but 24 is where movies use as standard (and has been for a very long time). 24*5 = 120, 24*6 = 144

I want to experience a truly high-refresh monitor some day, I've not owned a monitor with a more than 60hz limit since CRT days.

I know why this matters for TVs, but monitors? It seems odd that they would match refresh rate to movie standard but not for 60 hz monitors. Why don't normal monitors run at 48 hz or 72 hz then

[Enderman]

24 * 6 = 144

When binning displays they probably found there was enough yield for a 144Hz model but not more, so this became the standard.

There are 165Hz and 175Hz monitors and whatever now though.

60Hz is a doubling of 30Hz used by NTSC. Meanwhile 24Hz is used in the PAL system

It's the highest refresh rate you can do 1920 x 1080 over HDMI 1.3 or 1.4 or dual link DVI at, and the highest refresh rate you do 2560 x 1440 over HDMI 2.0 at, so that may have something to do with it.  Take a common resolution and push it out as fast as you can over the commonly used interfaces, and it makes sense to build screens for that number.  Go slower and you leave performance on the table.  Go faster and, well, it doesn't work... although, that hasn't stopped 4K 144 Hz panels from coming out on DP 1.3 which can only push it to 120 Hz.

idk to be honest what is special , all i know i have 27ich 1440p 144hz 1ms IPS monitor and its awsome

I want that but I am missing a key ingredient.
