Comparing the PA27JCV to speedy gaming monitors doesn’t make much sense, so for this review, I’ll share test results and comment on them relative to the expectations of a reference-level professional display.

Pixel Response and Input Lag

· Response Time Full black-to-white transition – 16ms

· Absolute Input Lag Full black to white transition – 41ms

Clearly, the PA27JCV is not a gaming monitor. Its inclusion of overdrive and Adaptive-Sync is there for game content creators, but any final judgments of play performance will require a faster display. I was a bit bummed that VRR and overdrive can’t be used together. HDR also cancels the overdrive function. I noted that total input lag was better than nearly every 60 Hz monitor I’ve ever reviewed so that is a positive point.

Test Takeaway: The PA27JCV’s video processing isn’t game focused, but since it’s marketed as a content creation tool, it should have a faster refresh rate, good overdrive, and usable Adaptive-Sync. That would allow creators to evaluate their game titles on a single display. But I suspect the focus here is on photography given the high pixel density.

Viewing Angles

The PA27JCV has exceptional off-axis image quality for an LCD monitor. At 45 degrees to the sides, there is no reduction in light output and just a slight shift to blue. Gamma remains constant which means you won’t see any loss of detail. The premium anti-glare layer in use here clearly makes a difference. The top view is green and red in tone with around 30% less light and a reduction in gamma.

Screen Uniformity

· Screen Uniformity Deviation From Center 0% Black Field – 10.74%

The PA27JCV doesn’t have uniformity compensation like some professional screens but given the above result, that’s not a big deal. It’s a sample-specific number so some screens will measure better, and others might show a little bleed or glow around the edges.

    A general observation: 5K monitors all seem to ship with DP1.4, and limted to 60Hz refresh, or at best 72Hz.
    Why oh why is the industry not moving to DP2.1 and higher refresh rates?

    Graphics cards such as the 7900XT and XTX have had DP2.1 since release, but Ive yet to find a good quality, affordable, 5K monitor that utilises DP2.1.

    The issue is that there are tiers to DP 2.1, which most people aren't aware of. DP 2.1 has 3 tiers of performance relative to bandwidth: UHBR 10, 13.5, and 20. Only UHBR 20 is appreciably superior to HDMI 2.1, and RDNA3 only supports the 13.5 standard.

    That said, most professional-oriented monitors still aren't pushing for higher refresh rates. For instance, Dell's U4025QW is the only ultrawide productivity monitor they have that goes above 60hz, and it's $2000. I think most of these companies assume a professional won't see a benefit, or care, about higher refresh rate. It may be true, but I think adopting 120hz and up would be beneficial to plenty of professionals, they just don't really know or care about it.

    Agreed, 120Hz would be a boon even just for day-to-day usage. Ive been using Dell flat panels in dual head configuration for over 20 years: the old 2003FPW had a great 16:10 aspect ratio, which gave me greater vertical resolution and in dual head I had a fantastic horizontal workspace. I upgraded in 2012/13 to 2713HBs, great 2160x1440, albeit at 16:9. Back then, the 60Hz refresh wasnt an issue.

    I upgraded to a single 5K monitor, as dual screen FPS gaming or Elite on a dusl screen has an issue - the cross hairs are of course where the monitor edges are! Tricky...!

    But moving to an LG 5120x2160 bought its own issues... the monitor can't do >72Hz on Thunderbolt/USB-C, and the DP1.4 input is limited to 60Hz.

    To respond to your last comment, I dont think professionals are aware of refresh rates/benefits higher rates brinng.

    Well Dell's 5K x 2K 40" U4025 is 120Hz. Sure it's only 2160 vertical not 2880, but that's still excellent.

    I can't believe anyone would want a 5K in 27" size. Even a child with excellent eyesight would struggle with 100% scaling on a 32" version let alone 27". This would need 175% scaling for most people.

    I'm getting the Dell which has 139dpi and can be run with 125% scaling still giving one 4073 x 1728 desktop.

    Article says "the 163ppi found in a 27-inch display is about as dense as it gets, until now." The LG UltraFine 5k launched in 2019 @ 218 ppi, also at 60Hz, also with support for 10-bit color.

    I assert there are actually two historical story threads that are relevant, neither of which is mentioned in the piece:
    1. The Windows-world is waking up to the fact that 4k @27" is a bad resolution because the pixel density makes for awkwardness at 1x (too small) and 4x (too big) and anti-aliasing in-between is bad.
    2. Asus is swinging for the fences with their ProArt series—what role does this display play in those ambitions?

    Separately, I don't understand the productivity benefits to professionals of 120Hz outside of game production/consumption, and even within gaming pretty much exclusively for FPS. Maybe I'm missing something. LMK,

    Imho the current sweet-spot is 6k at 32" in a 16:10 format, but there is almost nothing at that resolution and ratio except Apple's absurdly-priced XDR and Dell's bizarre webcam-only U3224KB. Apparently LG announced something at CES (32U990A) but without pricing. I'm curious about how long it will take Asus to do something in this format in the ProArt series.

    EDIT: Looks like I missed the announcement of the ProArt PA32QCV which supports "only" Thunderbolt 4 but otherwise seems to use the same panel

    Like everyone else in the comments, love the resolution, do wish it had the option to run VRR higher than 60hz. For productivity task this is great, but it should be capable of so much more if they were more aggressive. I agree that at 27" 4k is way to small, and run 1440p, would love to have the 2x scale 5k brings. Apple got this right, Wish the market would follow.

    It's mostly for comfort viewing reasons. I sometimes get eyestrain from 60hz monitors, which is something 120hz would help alleviate. It's not terribly beneficial for my tasks, it just feels more smooth and responsive.

    That Dell looks quite nice. I wonder how IPS Black compares to the HDR Nano IPS on the LG.

    And its Dell... I like Dell :)
