NVIDIA Demos Zero Latency Display Running at 1700Hz

Nvidia is demonstrating a display that holds a true refresh-rate of 1700Hz. It is a prototype called zero latency display and it can display imagery stable even when shaking the screen, handy for VR.

During its GTX 2016 event demoed the setup on which the Nvidia logo and name where shown, during that process the display was heavily vibrating and moving over a rails system on which it was mounted. The image however stayed stable in the center.

According to vice-president of Nvidia graphics research, David Luebke this was possible due to the high refresh rate which is roughly 20x higher opposed to what current VR goggles are using. At 90Hz each 11ms an images is displayed, at 1700 Hz that's 0.58 millisecond. 90Hz is more than sufficient for a comfortable VR experience, NVIDIA Vice President of Research David Luebke says that ever higher refresh rates could improve the VR experience by further reducing latency.

This is not just zero latency (0.58ms) between frame ready to be displayed and nearest refresh.
This display is also practically zero latency between frame sent and being fully displayed. Which is something entirely different than just 1700Hz display.

And which is demonstrated by image staying fixed to our eyes - a feat that high refresh alone would not be able to achieve, because it also also needs infinitesimal input latency.

Elimination of all kinds Vsync worries is just a nice bonus.
And no you don't need 1700 fps to experience benefits of 1700Hz display :rolleyes:

Perfect display, too bad I don't see this coming in the near future.
And certainty not at popular prices

True, if the gpu could actually output that refresh-rate, then, actual 1700hz would be possible. Considering the purpose of G-sync, though, which is to output non-vsync without tearing it makes more sense that this is like those Panasonic TV's that say they output 600hz to stabilize image quality.

Sadly not many people realize this.

I remember also seeing low fps image captures some time ago that showed that 1000 Hz polling on a mouse also decreases tearing (albeit marginally) due to a slightly smoother camera motion updates ingame.

There's so many latencies going on in tech that it's always good news when they succeed at reducing them.

will this be like infamous OLED tech ?? which was announce almost decade ago and still isnt widely available, not sure I want to know what the price might be seeing what is charged for gsync
