PSA: The purpose and origin of 144hz.

[Ranzear]

I see a lot of 144hz love around here, but I feel that it's just for the bigger number.

144hz comes from being six times the 24 frames per second of standard film. When you see a 3D movie it's in 24fps, and each frame is repeated three times for each eye: Left-Right-Left-Right-Left-Right. This reduces flicker (24hz per eye would be intolerable) without needing more frames.

So 144hz is coming from a 3D film standard. It's not intended for motion smoothness, and it's a bit too high for standard DVI connections used on the monitors discussed around here. It produces additional crosstalk on any strobed monitor, and sometimes forces lower bit depths despite Windows claiming 32bit.

Meanwhile 120hz is a multiple of the 30 or 60 fps intended by most PC gaming, which lacks the gratuitous "cinematic" blur of film process. It's what many of these screens are actually designed for and won't conflict with locked 60fps or, Gaben forbid, 30fps frame rates with VSync enabled.

Just thought it might be of interest around here as to why 144hz is an option, but perhaps not exactly the one we're all looking for.

Yeah, well, I also have that theory about 144Hz, because it's obvious. Unfortunately, 3D Vision doesn't work over 120Hz. I wish it worked, as it would decrease the glasses flickering and it would be perfect for 3D movies.
For now, my only solution for 0 judder in movies is using 3D Vision at 100Hz, and increasing the speed of the video with reclock to 25fps. I also tried black frame insertion after that in order to not have motion blur .

Edit: SVP also worked fine at 120fps, using frame interpolation. But my previos method is for original fps only.

i wish 25/50/100 fps would just become standard instead of 24 30 and whatever

but probably it's like wishing the us would switch to the metric system
lol

144Hz has less input lag than 120Hz, so it's important for games.

confirmed, i get twice as many kills with 144hz than with 120hz. 1ms less frametime is very important

Agreed.

Higher is better. Even if its only a 24Hz difference, I'll take it.
For all the benefits that encompass higher refresh rates. Which are by no stretch of the imagination only limited to just latency.

But on lcd, if strobe is only available in 120hz, tests show it is better to use 120hz with strobe then 144hz without, because of much better motion blur reduction (eye tracking issues).

120Hz Strobbed flickers too much for me, unfortunately.

have you actually seen 120hz strobed...

strobing isn't without disadvantages... you can't just immediately say one mode is better to use.
