G-SYNC monitors supports strobing at 85Hz and at 144Hz

UPDATE: This is old information, posted before G-SYNC was released. Blur Busters now has a G-SYNC monitor (see Our Preview of G-SYNC) with ULMB. 85Hz strobing is confirmed, however, 144Hz strobing is not available.

Good news for people who want “LightBoost” style strobing at other refresh rates, to reduce GPU requirements (85fps @ 85Hz) or to reduce input lag (144fps @ 144Hz) during low-persistence mode!

The web has revealed several clues about G-SYNC’s optional fixed-rate strobe mode:
(A) The G-SYNC upgrade datasheet has 85Hz added.
(B) AndyBNV suggested on NeoGAF the low-persistence mode is superior to LightBoost.
(C) The YouTube video of John Carmack at G-SYNC launch, was very suggestive.
(D) Many articles mentions 85Hz as a CRT frequency that stops flickering for many people.
(E) The pcper.com livestream suggests a very high fixed refresh in low-persistence mode.

Upon analysis, both 85Hz and 144Hz are available strobed modes with G-SYNC, in addition to existing common 100Hz and 120Hz strobed modes, like today’s LightBoost. More strobed modes (e.g. 60Hz) might be available. You heard it here first at Blur Busters.

A latency-friendly interpolation method has been developed for rendering games.

Also, one important innovation for the ITU-Rec. BT.2020 UHDTV spec is a new side channel signaling method. This can be used to send data for very quick high-quality frame interpolation and super-resolution reconstruction. It’s a bit similiar to the above technique.

I see.. using the time to the previous frame could work if there is little frame time jitter. If the frame times randomly spike, there would probably be flickering though I don’t really have an idea how bad it would be. As for fixing the color inconsistencies, there would need to be a lot of calibration since presumably the backlight’s strobe length can change every frame. G-sync won’t magically fix the problem, but assuming that g-sync supports instantly switching between different calibrations for difference backlight modes, it is still up to the manufacturers to get the calibration data.

One thing that makes me wonder – why strobing is supported only on fixed refresh rate?

Somebody make IPS panel with [email protected] and gsync. I will not buy TN.
