I really hate it when questions are put this way. Forget about need. Needs are food, water, shelter, health, etc.
Why can't we just ask, "would anyone really benefit from 1khz gaming display?" Then we can discuss the merits of the subject and whether there's actually a reason to move to it or if it's just more marketing and dick waving points.
It feels like asking if anyone "needs" it is unnecessarily loaded with snark and judgment.
Remember "Monster Cables"? Everyone had to have car-battery cables to connect their speakers?
Remember when somebody asked "audiophiles" to compare "Monster Cables" and alternatives? Their preferred speaker wire was just a straightened-out metal coat-hanger?
It's extremely easy to tell the difference. I can't tell you what's wrong with their experiment as I don't know exactly what they did, but they clearly fucked it. If you're looking at a static image, you can't differentiate 240Hz from 30Hz. You need a test that actually demonstrates the difference.
I have yet to draw the comparison in person (only have a 165Hz), but I mean, every time you double the FPS, the benefit of doubling them again halves. Going from 120 to 240 to 480 Hz is going from 8 to 4 to 2 ms in terms of frametime.
A 4 ms difference in delay might be somewhat noticeable, if you have a very well running game and amazing reflexes. Anything beyond 240 is marketing bs / e-sport 'I need every ms I can get'.
My processor has a boost clock speed of more than 4Ghz - My display just has to keep up with this, otherwise I wouldn't be a real gamer!!!!111oneeleven
One of the big benefits of 144 and 120 over 60hz display is actually how well they render lower frame rate content. Watching a 24fps (so cinematic!) movie on a 144hz ``display results in a new frame every 6 refreshes (or 5 for 120hz). With a 60hz display, you get an new frame every 2.5 refreshes. Generally this results in judder where every other frame is displayed for longer than the others
Does anyone need quad core? Does anyone need 1Tb of storage? Does anyone need more than 4GB of ram? Does anyone need...? Is a question we've asked time and time again in the modern history of computers. And the answer is always the same; not right now, but yes
Clearly not the same thing. There's no mechanism built into your very physiology that makes you biologically unable to make any meaningful use of anything above a certain amount of computer memory.
I posted this in another thread but there are some applications where this display technology is actually needed. For example with VR/AR having a 1000Hz display would mean each frame is only displayed for 1ms. Being that quick would mean the headset would be able to better display the micro movements your head and body makes which inturn reduces the disconnect and motion sickness people get with VR/AR.
90hz is generally enough for most people to not get motion sick. Some headsets do 120 which is like 8ms frame time. Humans can barely detect a flash of light that lasts for that long.
