Delayed past its original late 2017 timeframe, let alone the April and May estimates, NVIDIA’s G-Sync HDR technology finally arrived over the last couple months courtesy of Asus’ ROG Swift PG27UQ and Acer’s Predator X27. First shown at Computex 2017 as prototypes, the 27-inch displays bring what are arguably the most desired and visible aspects of modern gaming monitors: ultra high resolution (4K), high refresh rates (144Hz), and variable refresh rate technology (G-Sync), all in a reasonably-sized quality panel (27-inch IPS-type). In addition to that, of course, are the various HDR-related capabilities with brightness and color gamut.
Individually, these features are just some of the many modern display technologies, but where resolution and refresh rate (and also input latency) are core to PC gaming, those elements typically work as tradeoffs, with 1440p/144Hz being a notable middle ground. So by the basic 4K/144Hz standard, we have not yet had a true ultra-premium gaming monitor. But today, we look at one such beast with the Asus ROG Swift PG27UQ.

As an ultra-premium gaming monitor of that caliber, the PG27UQ also has an ultra-premium price of $1999. For reasons we’ll soon discuss, the pricing very much represents the panel’s HDR backlighting unit, quantum dot film, and G-Sync HDR module. The full-array local dimming (FALD) backlighting system delivers the brightness and contrast needed for HDR, while the quantum dot film enhances the representable colors to a wider gamut, another HDR element. The new generation G-Sync HDR module deals with the variable refresh implementation, but with HDR, high refresh rate, and high resolution combined, bandwidth constraints require chroma subsampling beyond 98Hz.
In terms of base specifications, the PG27UQ is identical to Acer’s Predator X27 as it uses the same AU Optronics panel, and both monitors are essentially flagships for the G-Sync HDR platform, which includes the curved ultrawide 35-inch models and 4K 65-inch Big Format Gaming Displays (BFGD). Otherwise, there isn’t anything new here that we haven’t already known about in the long run-up.

Furthermore, Asus’ ROG Swift PG27UQ also had a rather insightful channel for updates on their ROG forums, so there's some insight into the panel-related firmware troubles they've been having.
How We Got Here: Modern Gaming Monitors and G-Sync HDR
One of the more interesting aspects about the PG27UQ is about its headlining features. The 3840 x 2160 ‘4K’ resolution and 144Hz refresh rate are very much in the mix, and so is the monitor being not just G-Sync but G-Sync HDR. Then there is the HDR aspect, with the IPS-type panel that has localized backlighting and a quantum dot film. G-Sync HDR means both a premium tier of HDR monitor, as well as the new generation of G-Sync that works with high dynamic range gaming.
Altogether, the explanation isn’t very succinct for gamers, especially compared to a non-HDR gaming monitor, and it has all to do with the vast amount of moving parts involved in consumer monitor features, something more thoroughly covered by Brett. For some context, recent display trends include
- Higher resolutions (e.g. 1440p, 4K, 8K)
- Higher refresh rates (e.g. 120Hz, 165Hz, 240Hz)
- Variable refresh rate (VRR) (e.g. G-Sync, FreeSync)
- Panel size, pixel density, curved and/or ultrawide formats
- Better panel technology (e.g. VA, IPS-type, OLED)
- Color bit depth
- Color compression (e.g. chroma subsampling)
- Other high dynamic range (HDR) relevant functions for better brightness/contrast ratios and color space coverage, such as local dimming/backlighting and quantum dot films
These features obviously overlap, and much of their recent developments are not so much ‘new’ as they are now ‘reasonably affordable’ to the broader public. For a professional class price, monitors for professional visualization have offered many of the same specifications. And most elements are ultimately limited by PC game support, even uncapped refresh rates and 4K+ resolutions. This is, of course, not including connection standards, design (i.e. bezels and thinness), or gaming monitor features (e.g. ULMB). All these bits, and more, are served up to consumers in a bevy of numbers and brands.
Why does all of this matter? All of these points are points of discussion with the Asus ROG Swift PG27UQ, and especially to G-Sync HDR at the heart of this display. Gaming monitors are moving beyond resolution and refresh rate in their feature sets, especially as games start to support HDR technologies (i.e. HDR10, Dolby Vision, FreeSync 2 tone-mapping). To implement those overlapping features, much more has to do with the panel rather than the VRR hardware/specification, which has become the de facto identifier of a modern gaming monitor. The goal is no longer summarized by ‘faster frames filled with more pixels’ and becomes more difficult to communicate, let alone market, to consumers. And this has much to do with where G-Sync (and VRR) started and what it is now aspiring to be.

SLI & Crossfire are succeeded by DX12's & Vulkan's explicit multi-GPU mode. Nvidia deleiberately even ported NVLINK (succeeds classic SLI) to RTX cards from Quadro+ cards but without memory pooling because DX12 & Vulkan already provides that for GPUs.Devs have to use DX12 or Vulkan and support such features that is easier for them to consider now that Windows 8 mainstream support is over + ray-tracing that's available only on DX12 & Vulkan.

Still cheaper than my Sony FW-900 CRT was when it was brand new! LOLHixbot - Wednesday, October 3, 2018 - link
Still not better than a fw-900 in many ways. This LCD doesn't have a strobing feature to reduce eye tracking motion blur.nathanddrews - Wednesday, October 3, 2018 - link
No argument there, but my FW900 died, so the options are few...Crazyeyeskillah - Wednesday, October 3, 2018 - link
my fw-900 is also dead in my closet, hoping of resurrecting it one day. Right now I got another excellent crt monitor I found to game on: Sony Multiscan E540 : It's not as big, but god damn is it smooth and flawless.By the time this crt dies, hopefully LCD tech won't be such garbage trying to make workaround for its inferior tech for gaming.

Yeah, I've moved on to a Sony C520K for the last ~2 years. In use I think it's far better than my FW900 was in terms of contrast/color plus I'm able to push slightly higher refresh rates, but it's not widescreen. I have bought a couple expensive G-Sync displays, hoping for an adequate replacement, but ended up returning them. I'm really hoping that this CRT lasts until MicroLED hits the market and that mLED can truly combine the best attributes of LCD and OLED without any of the drawbacks.Ironchef3500 - Wednesday, October 3, 2018 - link

I don't get the point. You don't need the features for desktop work, so this is purely a gaming feature. Why not get an equally capable OLED/QLED at a much bigger size for less money ?Inteli - Tuesday, October 2, 2018 - link
TVs don't support native high refresh rates from sources like monitors do (I think LG's does, but only from USB sources or something like that) or adaptive refresh rates. It's a gaming monitor, so it has gaming-specific features.imaheadcase - Tuesday, October 2, 2018 - link
You answered own question, because its a gaming monitor. You can't find one like this (yet) that offers all the things it does.You like many people are confused on this website about TV vs monitors. A TV equal size, same resolution, is not the same as a dedicated monitor. A LG OLED 55 inch TV looks pretty bland when you use a PC monitor for gaming.
