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.
You absolutely can tell the difference between 90Hz and 1kHz. Just draw a squiggly line! See this video for a rather dramatic demonstration:
This is a demonstration of latency, not frame rate. Did you intend to link something different?
A 1000Hz display necessarily has a latency of 1ms between frames. For 100Hz, that’s 10ms.
But this is only the lower bound. You have to include all other sources of latency, such as software, input hardware, drivers, graphics card, etc.
Ahhh, now I see the connection! It’s the update interval. I had to chew on it for a minute but the math checks out.
yes, but, it reduces the computation cycle for that frame to 1ms.
as a dev, that’s daunting.
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’m not sure, but know the tech would be great for vr. Every jump - from 60 dk1 to vive’s 90 and index’s 120 have been great.
Getting closer to emulating CRT scan lines
No.
I have a 240hz display and I think it’s enough for me
Type of games I play, I’m fine with my 120 and fps locked at 60.
Wait, we already have 480 Hz displays?
540 Hz already.
does it matter if we cant afford it
Considering HDMI 2.1 and Display Port 1.4 can’t run that fast…hmmm… no.
1 kHz is mid tier, real gamers use 1 MHz refresh rate.
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
Maybe VR could use this with some combo of hdr and variable refresh rate.
i don’t
i have a 144hz display, and can barely tell the diffrence between that and 60hzDo make sure you have set it to 144hz in advance display settings if your running windows.
yeah, i changed that.
i only discovered that setting after a few months,
but now it has been on for years.i can tell the diffrence if i actively look out for ghosting on my mouse coursor.
but unless i actively look out for it,
i dont notice it
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
Wouldn’t by that logic also be impossible to show 60fps content at 60 fps in a 144 monitor?
Does anyone really need a 1,000 Hz gaming display?
yes
Does everyone?
no
Need, no. Want, YES.
Going from 144 to 280 was great, so if 1k Hz could become the next best thing maybe 480/540 will become affordable.
Professional video editors/content creators etc. Not for gaming that’s for sure.
Professional editors make things in 24 fps so that’s all they need actually
Uh, high speed camera shots?
Which is then displayed at a way slower framerate, there’s no point in which they need to display the content in the real framerate on the screen.
And how can you be so certain of that?
Would love to see a movie mastered in 1kfps though lol
Remember that blind test on LTT where no one, including an esporty player, could reliably differentiate between 120 und 240 Hz?
I know it’s not exactly the most thorough experiment ever, but it’s all I needed to know.
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’.
