HDR performance
It is what it is. The PG279QM lacks contrast, the built-in edge-lit dimming with its 16 zones is better than nothing, but it is simply not enough to really bring true HDR to the screen. As a rule, HDR mode makes the displayed image much brighter. Which can be helpful under certain circumstances if you want to see more when gaming in dark rooms. However, if it happens that dark and very bright scenes have to be displayed at the same time, the usual blooming (or holo effects) happens. Fortunately, ASUS doesn’t advertise HDR too aggressively, though I have to bring up a quote:
The extremely bright white and deepest black… blah blah? Well, marketing. I would wish for a bit more understatement from ASUS ROG here. Because: Only with full pants is good stink! And the PG279QM is not an HDR monitor, so unfortunately these pants are empty… The maximum peak brightness of the PG279QM (HDR mode) is usually 540 nits (10% window size) and about 470 nits (100% window size). That’s basically okay, but at the end of the day it doesn’t help to really pull the sausage off the plate in HDR gaming. In short: In complex HDR scenes, the monitor is an HDR aggravator and usually slightly better than SDR.
Gray Scale and Color Accuracy (HDR on, OSD Local Dimming Mode 2)
Measurement Report 3.8.9.3 – ROG PG279QM @ 0, 0, 2560×1440 – 2022-09-20 14-33
As most of you know, I can’t currently measure much more than that. However, the measurement shows an obvious weakness. There is a lack of contrast and brightness. The deviations are already not without. It’s a pity that the test alone is enough to cast a shadow on the otherwise very good PG279QM. Again, edge-lit dimming is usually part of the problem and not part of the solution.
Subjective overall impression
The color reproduction of the monitor is really one of the big standouts. Especially when you consider that ASUS advertises the monitor as a pure gaming monitor. The second – and probably most important – mainstay of the PG279QM is its motion clarity. I have never seen anything as cool as this before. Personally, I like ASUS ROG’s implementation: You have the best possible (as of 2021) smoothness 1440p 240 Hz, paired with super responsiveness. (Pixel Response and Latency) In doing so, ASUS has created a picture quality (Gray Scale, ColorChecker) that is second to none. Gaming is incredibly fun on the display. Being able to work in three different color spaces on one of the best gaming monitors justifies a lot. But more about that, there is on the last page.
