NVIDIA G-SYNC HDR Technology Explained!

Leave a reply

NVIDIA has been talking about the G-SYNC HDR technology for more than a year now. But now, they are finally ready to deliver the promise with actual G-SYNC HDR monitors! So here is a refresher’s course on NVIDIA G-SYNC HDR!

 

NVIDIA G-SYNC HDR Explained

NVIDIA G-SYNC HDR adds HDR (High Dynamic Range) capability to G-SYNC, which is a variable refresh rate technology that delivers smooth, tear-free gaming experience, when used with an NVIDIA GeForce graphics card.

Higher Brightness

NVIDIA G-SYNC HDR displays will have greatly increased brightness, with the ability to express deep saturated colours at a high brightness level. They will have the ability to produce at least 1000 nits of peak brightness, with support for the HDR10 format.

Greater Contrast

NVIDIA G-SYNC HDR displays will have a full array direct backlight, with at least 384 local dimming zones. This allows them to product contrast ratios of over 10,000:1. Traditional LCD panels with a global dimming backlight, in contrast, can only deliver contrast ratios of 1000:1 to 2000:1.

Wider Colour Gamut

The traditional sRGB colour space covers only about 35% of the colours the human eye can perceive. Hence, NVIDIA G-SYNC HDR displays will support the DCI-P3 colour space that offers 26% greater coverage of the visual spectrum than sRGB.

High Refresh Rate

NVIDIA G-SYNC HDR displays will support a high refresh rate using DisplayPort 1.4 with the High.Bit Rate 3 (HBR3) link. They will have the ability to display 4K at 144 Hz, instead of the usual 60 Hz for traditional 4K monitors.

 

The First G-SYNC HDR Displays

At the NVIDIA Computex 2018 press conference, and the follow-up GeForce tech briefing, NVIDIA showed off the first two G-SYNC HDR displays. They are both 27″ displays with what appears to be the same panel and key specifications. They both have a full array direct backlight, with 384 local dimming zones.

Acer Predator X27

The Acer Predator X27 (Price Check) is a 27″ 4K HDR display with a 144 Hz IPS panel, with a GTG (grey-to-grey) response time of 4 ms. It has a launch price of US$ 1,999.

ASUS ROG Swift PG27UQ

The ASUS ROG Swift PG27UQ is a very similar 27″ 4K HDR display with a 144 Hz IPS panel, with a GTG (grey-to-grey) response time of 4 ms. It has a 1000 nits peak brightness level, and a HDR contrast ratio of up to 50,000:1.

NVIDIA Computex 2018 – GeForce Updates + Demos

Leave a reply

Right after the NVIDIA Computex 2018 press conference, they gave us a private briefing on the latest GeForce updates, as well as demos of real-time ray tracing with NVIDIA DGX Station, the NVIDIA Big Format Gaming Display (BFGD), and NVIDIA G-SYNC HDR.

Again, if you are looking for news on NVIDIA Turing, we will have to disappoint you. As NVIDIA CEO Jensen Huang mentioned in his Q&A session, “it’s a long time from now” before Ampere is released. Still, there are a number of interesting GeForce-related technologies to check out…

 

NVIDIA Computex 2018 GeForce Updates

The session kicked off with a 34-minute long briefing on the latest GeForce updates.

Here’s a summary of the key points :

  • Since the latest Intel Coffee Lake mobile CPUs were introduced, there are now 85 new gaming laptops with GeForce GTX GPUs.
  • A year after NVIDIA Max-Q was introduced, there are now 25 laptop models built from ground-up with Max-Q design in mind.[adrotate group=”2″]
  • The Hunt Effect – increasing brightness increases the perceived colourfulness.
  • The Stevens Effect – increasing brightness increases apparent spatial resolution.
  • sRGB and DCI-P3 cannot display all of the colours in nature (represented by Pointer’s Gamut). Ultimately, the best possible colour gamut is Rec. 2020.
  • The first two NVIDIA G-SYNC HDR monitors are the Acer Predator X27 and the ASUS ROG SWIFT PG27UQ, and feature 4K HDR panels with a refresh rate of 120 Hz, that can be overclocked to 144 Hz.
  • Both G-SYNC HDR monitors have a panel with 384-zone full-array direct backlight capable of 1000 nits brightness, with a DCI-P3 colour gamut with Quantum Dots.

 

NVIDIA G-SYNC HDR Demo + Comparison

Here is a demo and comparison of the Acer Predator X27 G-SYNC HDR monitor, with a “regular” Acer Predator XP1 G-SYNC monitor.

 

Real-Time Ray Tracing On NVIDIA DGX Station

NVIDIA also showed off real-time ray tracing on an NVIDIA DGX Station.

 

The NVIDIA BFGD (Big Format Gaming Display)

We also had the opportunity to check out the 65″ NVIDIA Big Format Gaming Display, which also features G-SYNC HDR.
