Still, if you shut down your PC when not using it, and keep your PC setup in a quiet room, the best course of action would be to completely turn off the monitor when not using it. With any other noise in the room, such as our test PC turned on, the fan noise was drowned out. It's worth noting that despite the monitor having an always-on active cooling fan, it was only noticeable with no other ambient noise in the room, and in close proximity to the display. While this isn't a problem for today, where graphics cards can barely hit 60 FPS at 4K, it is certainly something to be aware of when buying a $2,000 product that you would expect to last for quite a long time to come. One caveat though, with HDR enabled at 4K, the maximum refresh rate is limited to 98Hz. HDR: 98 Hz 10-bit RGB, 120 Hz 8-bit RGB (dithered, only with Win10 RS4), 120 Hz 10-bit YCbCr422, 144 Hz (overclocked) 10-bit YCbCr422 SDR: 98 Hz 10-bit RGB, 120 Hz 8-bit RGB, 144 Hz (overclocked) 8-bit YCbCr422
Here is the full capability of the PG27UQ across different refresh rates and modes: However, for a display this expensive, it's a negative that may this display age faster than expected. įor the moment, given the lack of available GPU products to push games above 98Hz at 4K, we feel like keeping the monitor in 98Hz mode is a good compromise. For more information on Chroma Subsampling, see this great article over at Rtings. While this shouldn't affect things such as games and movies to a noticeable extent, 4:2:2 can result in blurry or difficult to read text in certain scenarios. While it isn't the absolute highest claims of color reproduction we've seen on a display, these numbers still represent color accuracy in the top echelon of pc monitors.Įdit: For clarification, the 98Hz limit represents the refresh rate at which the monitor switches from 4:4:4 chroma subsampling to 4:2:2 subsampling.
ASUS claims the PG27UQ is capable of reproducing color to an accuracy of 99% of the AdobeRGB gamut, and 97% of DCI-P3. Of course, brightness isn't the only important aspect of HDR. The typical brightness of 600 nits is still higher than the measured peak brightness of any other HDR monitor we have taken a look at so far, an impressive feat.
As per the DisplayHDR 1000 specification, the display must be capable of both flashing the entire screen with an instantaneous brightness of 1000 nits, as well as sustaining a 10% patch in the middle of the display at 1000 nits indefinitely. On the HDR side, you have HDR10 decoding powered by a 384-zone Full Array Local Dimming (FALD) backlight, capable of reaching 1000 nits in certain scenarios. While there has been one other Korean monitor that has supported 4K 144Hz, the ASUS PG27UQ is the first widely available display to take advantage of this new 4K high refresh mode offered by DisplayPort 1.4. There's a lot of ground to cover with the specifications of the ASUS PG27UQ, and many of them represent industry firsts. Both displays represented the launch of an oft waited technology, in a 27" form factor, and were seen as extremely expensive at their time of release. In some ways, the launch of the PG27UQ very much mirrors the launch of the original G-SYNC display, the ROG Swift PG278Q. Even more slippages in release lead us to today, where the ASUS PG27UQ is available for pre-order for a staggering $2,000 and set to ship at some point this month. However, delays lead to the PG27UQ being displayed yet again at CES this year, with a promised release date of Q1 2018. On top of the HDR support, these monitors were the first announced displays sporting a 144Hz refresh rate at 4K, due to their DisplayPort 1.4 connections. With promised brightness levels of 1000 nits, G-SYNC HDR was a surprising and aggressive announcement considering that HDR was just starting to pick up steam on TVs, and was unheard of for PC monitors. Originally demonstrated at CES 2017, the ASUS ROG Swift PG27UQ debuted alongside the Acer Predator X27 as the world's first G-SYNC displays supporting HDR.
In the computer hardware world where we are generally lucky to know about a product for 6-months, the PG27UQ is a product that has been around in some form or another for at least 18 months. To say that the ASUS ROG Swift PG27UQ has been a long time coming is a bit of an understatement. We finally have the ASUS G-SYNC HDR monitor in our hands!! Is it worth 00?Ī long time coming We finally have the ASUS G-SYNC HDR monitor in our hands!! Is it worth $2000?.
