G-Sync & ULMB Usable at the same time! (Demoed on XB252Q)

Looks like Nvidia want's to bring G-Sync+ULMB to the main stream!

Toms Hardware (French): http://www.tomshardware.fr/articles/ulm ... 62461.html

Translated:
"The presentation was very convincing: a fast drop-down menu became perfectly readable once the G-Sync and the ULMB, up to 144 Hz. The image quality was amazing and would be beneficial for all users with a compatible screen. Note that if the graphics card delivers only 70 frames per second, the images will be doubled to 140 Hz with synchronized ULMB frequency. An image doubling that already existed before at low frequency, but without synchronous ULMB.

According to NVIDIA, the new ULMB standard has two advantages: the 144 Hz management and a lower reduction in brightness . The old version was limited to 120 Hz. There is always an impact on the brightness, but it is negligible in our opinion and it represents a very reasonable compromise with regard to the gain of clarity obtained."


ULMB will now work at 144hz, with G-Sync AND with less brightness loss then the 'previous version'. IMO Nvidia is very protective of their technology and only want ULMB settings that will result in the best picture quality, this leads me to believe that they will be using the VT tweaks to achieve the brightness boost and 144hz with little to no crosstalk.

Also something to note is that G-Sync+ULMB feature will use image doubling, something that was used when your framerate dips below your monitors minimum framerate, but this time it looks like it will be doubling anything lower then 72fps, this leads me to belive that this has something to do with dealing with the problem of fluctuating brightness with the hacked G-Sync-ULMB that Masterotaku originally found.

So we know that some monitors already work with ULMB and G-Sync and they could be 'switched on' to allow this feature but some monitors did seam to work with hacked G-Sync+ULMB trick and the new ULMB features will require VT tweaks for them to work. So it's currently not known if any of our previous monitors will be enabled to work with any of these features.

The monitor at the show demoing this tech was the Acer XB252Q 240hz with currently you can buy without these features.

I hope they can add this to existing monitors through the driver. Otherwise, it will be at least 5-6 years before I can even consider changing monitor :-P

Fantastic info to see more GSYNC+ULMB stuff.

Also, we have a post on the main site too:
Combining strobing (ULMB/LightBoost) with variable refresh (GSYNC/FreeSync)

P.S. To support Blur Busters here's the Acer XB252Q on Amazon.
(Currently, Blur Busters uses Amazon links at this time, but we will try to add NewEgg in the future too.)

Not sure yet. Anxiously waiting with baited breath!

Wow, very interesting. I'd love to try this on a 1440p monitor.

Do You think guys we can expect gsync+ulmb in this year? Any new information from Nvidia?

Why do I have a feeling Masterotaku will soon be working for Nvidia?
