Colour accuracy was less consistent around the display, but if it hadn’t been for the measurement report I likely wouldn’t have noticed, as colours remained vibrant across the display. If you’re doing colour critical editing work this may be of concern, but for gaming and movies, it’s perfectly acceptable. dE colour accuracy – a wide range of colours are tested and the colour accuracy dE measured. We compare these produced colours to the sRGB reference space, and if applicable when measuring a wide gamut screen we also provide the accuracy relative to a specific wide gamut reference such as DCI-P3. An average dE and maximum dE is provided along with an overall screen rating. The lower the dE the better with differences of <1 being imperceptible (marked by the green area on the graph), and differences between 1 and 3 being small (yellow areas). Anything over dE 3 needs correcting and causes more obvious differences in appearance relative to what should be shown There is no integrated cable management system on the AGON AG274QZM, but AOC includes a pair of 3M-adhesive cable tidies to help keep your setup neat. The default gamma was largely very close to the 2.2 target, dipping a bit low in the lighter grey shades and leading to a 2.15 average overall. Nothing of any real issue there though. RGB balance was pretty good, being only a little low in the green mix. But the resulting colour temp was good across the greyscale with 6497k average (0% deviance). It also offered a reliable white point only marginally off the target at 6460k (1% deviance). This all resulted in a respectable and pretty decent 2.1 dE average for the greyscale accuracy. The luminance was high at 356 nits and so the brightness setting will definitely need to be turned down from the default 70. The contrast ratio was reasonable for an IPS panel and on spec basically at 992:1. Apart from that, HDR is implemented well and really shines in brighter scenes. Whether it was traveling across a dusty desert in Horizon Zero Dawn with the sun overhead, or swinging through a snowy Manhattan in Spider-Man: Miles Morales, there is a richness and depth to the colors and highlights that are more discernible than in SDR. This is likely due to the panel’s ability to output true 10-bit color when HDR is enabled, even at 240Hz. Still, when exploring dark caves in Horizon Zero Dawn, it felt more “dusky” than truly dark.

For everyone else, it’s probably overkill; I couldn’t really tell the difference between games running at 240Hz and games running at “only” 170Hz on my regular 1440p gaming monitor. That’s about the standard for mid-tier monitors these days, and it’s even possible to buy a truly excellent 27-inch, 1440p gaming monitor that can still hit 240Hz like the Alienware AW2723DF for literally half the price. All in all it’s a reasonable setup in HDR mode, although the image does look a bit washed out and there are some higher errors in these measurements if you consider luminance error as well (not shown above). It should be fine for HDR gaming and movies really, but isn’t accurate enough for any HDR content creation or professional work. Conclusion There’s no shortage of colour, either. AOC’s screen produced 99.8% of the sRGB gamut at 168.6% volume and 92.6% of the DCI-P3 space at 119.4%. it even churned out 99.2% of the Adobe RGB space at 116.2%, which is an excellent result for any gaming display. The Delta E of 1.98 is impressive too and means you won’t have any accuracy issues. One of the most notable complaints with the alienware or LG OLED monitors is that text is blurry. This extends to the LG C2 as well. IMO this is a dealbreaker because being a PC monitor means having text on screen in most cases, often of smaller sizes, and impairing the ability to read that is going to diminish the experience greatly.
There is some moderate improvement to “local contrast” in HDR, measuring ~3080:1 between adjacent bright and dark areas on a 10% area bright pattern test. We measured a peak brightness of ~1262 cd/m 2 in HDR mode which was a higher than the spec even. This was not possible on the smaller bright areas due to size of the local dimming, but for 10% windows and above we had a high peak brightness capability. This was even possible with full screen sustained brightness. Further measurements for peak brightness are captured below. Your phone adjusts brightness regardless of whether the sun is directly hitting it or not. Ambient light levels are much higher outside of course but that wasn't the point of my example, it was to point out that higher ambient light levels require higher levels of brightness to properly see the screen. Surely you did not think that I was saying that outside midday lighting is normal inside lighting.Sorry maybe I ran with it a bit - but I do believe you also ran a bit with the LCD is better stance 'because of higher brightness'. Bright screens were never a real perk, and when OLED's 'benefit wanes', is not generally the situation where it matters - when it does matter, you'll make sure its benefit doesn't wane by just closing a curtain. The screen can offer the colour enhancements associated with HDR content with 98% absolute / 115.9% relative DCI-3 coverage measured. Also for comparison there’s 83.7% of the Rec.2020 space covered which is very good, and that’s the colour space HDR content is mastered in. This is higher coverage than many other wide gamut screens on the market. There is also a 10-bit colour depth support The AG274QXM is one of AOC’s most recent additions to their “AGON Pro” line-up of gaming monitors. Some of the specs might be considered fairly standard or common nowadays, with a 2560 x 1440 IPS panel and a pretty modest 170Hz refresh rate – much higher refresh rate 1440p options are available on the market nowadays, such as the recently tested Gigabyte Aorus FI32Q X with 270Hz. Then there’s common IPS technology specs like a 1000:1 contrast ratio, wide 178/178 viewing angles; and also colour enhancements like wide colour gamut and 10-bit colour depth that you’d find on most modern gaming screens. That’s not to say any of this is bad, it’s just fairly typical in this space.

evernessinceNo, that's an assumption you made. If you read my priors, I specifically state on multiple occasion that the benefit under typical lighting condition of OLED wanes. I also made an argument that current OLED monitors (I'm putting more qualifiers here because you seem drawn to misinterpreting things) are too dim to be used in all environments, which is 100% true. After calibrating the monitor and dialing in the settings, it also proves vibrant and color accurate. I measured 99.8% coverage of the sRGB color space, which is standard, but also a very respectable 92.7% of the DCI-P3 color space and an excellent 96.7% of AdobeRGB. While that might sound like the AGON PRO AG274QZM is well suited for creative work like photo and video editing, the color reproduction might not be accurate enough. Color Setup has a 6-axis color adjustment plus three color temp presets. The user mode has precise RGB sliders that help achieve pro-level grayscale accuracy for both SDR and HDR. The Audio menu includes a toggle for DTS sound processing. Turning this on improves the audio by expanding the soundstage. It also sounds a little less tinny though you won’t hear any serious bass from the internal speakers.Contrast ratio: 1,000:1 (rated), 80 million:1 (rated dynamic contrast ratio); 1115:1 (tested, local dimming disabled) The panel response of the AG274QZM is excellent. In my testing, setting the overdrive to Weak garnered the best results, effectively eliminating motion blur. Responsiveness is very slightly improved with the Medium preset, but this introduces slight overshoot, whilst the Strong overdrive setting further increases overshoot and introduces some mild inverse ghosting, though not to the levels of some other panels we’ve tested. Max brightness of my OLED still is higher than the display I replaced so it's not exactly a deal breaker for a lot of people upgrading. I can understand if you were going from 600+ nits sustained down to whatever but most people are sidegrading the brightness at worst and thats for those at max brightness anyway. It’s a practical panel, too. It’s got 120mm of height adjustment and tilt, swivel and pivot movement alongside 100mm VESA mount support. The KVM switch allows multiple PC or device control from one set of peripherals and on the side it has a headphone hook.
Great Deal
