Why the three-way question collapses to two
The search is for IPS against VA against OLED, and none of these eight monitors uses a VA panel. Seven are IPS-family panels: standard IPS on the three Asus ProArt displays and the BenQ SW272U, and Dell’s IPS Black on the three Dells. The eighth, the ROG Swift PG32UCDM3, is a self-emissive Tandem QD-OLED. If VA is what you came for, this lineup cannot answer that part, and the comparison the published figures support is IPS and IPS Black against OLED.
The figure that separates those is native contrast. The PA32UCXR reaches 1,000,000:1 only in HDR, where its 2,304-zone Mini-LED backlight dims regions independently, and sits at 1,000:1 otherwise. The PG32UCDM3 has no backlight: each pixel emits its own light, and Asus publishes no numeric contrast ratio for it in the Gen3 material retrieved.
Refresh rate and variable refresh are separate lines on the sheet
The maximum refresh figures split the eight cleanly. Four are fixed at 60Hz: the Dell U2723QE, the ProArt PA27JCV and PA32UCXR, and the BenQ SW272U. The ProArt PA278CFRV reaches 100Hz, the Dell U3225QE and U2724DE reach 120Hz, and the PG32UCDM3 reaches 240Hz. For a word processor, a spreadsheet or a static photo, the number does not change what is on screen. It matters once content moves quickly, and it only pays off at 120Hz or 240Hz when the graphics card and the game can deliver that many frames.
Variable refresh is a different line, and fewer of the eight publish it. The PA278CFRV lists Adaptive-Sync across a 48 to 100Hz range. The PA32UCXR lists Adaptive-Sync across 40 to 60Hz. Asus’s own spec sheet for the PG32UCDM3 lists no variable refresh mode. The three Dells publish no variable refresh mode, so for occasional gaming on an IPS panel the 100Hz PA278CFRV with published Adaptive-Sync and the 120Hz Dells without one are different propositions rather than a 20Hz gap.
Response time is the quieter half of motion handling, and here the seven IPS panels converge. All of them publish 5 ms gray-to-gray; the three Dells add that 5 ms is the Fast mode figure and Normal mode is 8 ms. The PG32UCDM3, the one monitor sold on motion, has no response time figure in Asus’s Gen3 spec pages at all.
Work out pixel density before you choose a resolution
Two 4K monitors in this group do not deliver the same sharpness. The U2723QE and SW272U put 3840 x 2160 on 27 in, roughly 163 pixels per inch by calculation. The U3225QE and the PG32UCDM3 put the same pixel count on 31.5 in, roughly 140. The PA32UCXR is marketed at 32 in but Asus does not state a precise viewable diagonal, so it sits in the same band as the 31.5 in panels without the figure being pinned down. The two 1440p panels, the U2724DE and PA278CFRV, land near 109.
Which band you want is a choice, not a ranking. Higher density renders text and fine interface detail more finely. Lower density at the same diagonal makes pixels and on-screen elements physically larger, which some buyers choose deliberately.
Gamut and Delta E answer different questions
The two smaller Dell panels show the gap: the U2723QE publishes 98% DCI-P3 and 100% sRGB, and the U2724DE 98% DCI-P3 and 98% Display P3, but neither page publishes a Delta E figure, so their accuracy claim rests on coverage alone.
The published Delta E figures run from the PA32UCXR’s under 1, backed by a built-in motorized colorimeter that recalibrates the panel without external hardware, through the SW272U’s average of 1.5 or lower with a factory calibration report, the U3225QE’s under 1.5, and the PA27JCV, PA278CFRV and PG32UCDM3 at under 2. The PA27JCV’s figure is Calman Verified; the SW272U adds Pantone Validated and Pantone SkinTone Validated marks. Those third-party marks add confidence but do not replace the number itself.
Adobe RGB is the coverage figure most of the group leaves out. Only three publish it: the PA32UCXR, the SW272U and the PA27JCV. If your workflow is specified in Adobe RGB, the other five do not give you a number to check. The PG32UCDM3 is the reverse case: 99% DCI-P3 and Delta E under 2, but no sRGB or Adobe RGB percentage published for this generation.
HDR: the certification tier tells you what the brightness figure does not
Three picks carry a VESA DisplayHDR tier on the manufacturer’s own page. The PA32UCXR is DisplayHDR 1400 with 1,000 cd/m² sustained full-screen and 1,600 cd/m² peak, driven by 2,304 local dimming zones, with Dolby Vision, HLG and HDR10. The U3225QE is DisplayHDR 600 at 600 cd/m² peak on a standard backlight with no local dimming. The PG32UCDM3 is DisplayHDR 500 True Black at 1,000 cd/m² peak with Dolby Vision and HDR10, True Black being the tier applied to self-emissive panels.
The rest publish weaker claims. The PA27JCV lists HDR10 with a 500 cd/m² HDR peak and no certification tier. The SW272U lists HDR10 and HLG at 400 cd/m² with no tier. The PA278CFRV lists HDR10 at a 400 cd/m² HDR peak; a retailer listing adds DisplayHDR 400, but Asus’s own techspec page does not. The U2723QE at 400 cd/m² and the U2724DE at 350 cd/m² publish no HDR support at all.
The Mini-LED PA32UCXR and the OLED PG32UCDM3 reach their contrast by opposite routes. The PA32UCXR keeps an IPS panel in front of a backlight split into 2,304 zones, which is why its 1,000,000:1 figure is labeled HDR and its standard figure stays at 1,000:1. The PG32UCDM3 has no zones to split because there is no backlight. The published figures do not support a claim that one looks like the other. They support only that the PA32UCXR carries no burn-in exposure and a 60Hz ceiling, and the PG32UCDM3 carries 240Hz and a burn-in warranty clause.
The OLED trade-off on a desk used for work
The PG32UCDM3 is the only pick where all-day static content is a stated ownership question. Asus’s eshop page states that its 3-year warranty includes panel burn-in coverage. Amazon’s listing for the same ASIN names an OLED Care Pro pixel-maintenance feature set, but the Asus spec and eshop pages retrieved do not restate that name, so the warranty clause is the firmer of the two protections. The seven IPS panels have no self-emissive pixels and the question does not arise for them.
Two other published details shape its fit as a work monitor. Its stand adjusts height across 0 to 80mm (about 3.1 in), tilts +20° to -5° and swivels ±15°, with no pivot listed, whereas the U3225QE, PA27JCV, PA278CFRV and SW272U all publish 90° pivot. Its connectivity is gaming-shaped: DisplayPort 2.1, two HDMI 2.1 ports, a 90W USB-C input and three USB-A ports, with no Ethernet and no KVM listed.
When a 60Hz monitor is the right answer
If the desk is for documents, code, spreadsheets, photo or video editing, and gaming is not in the picture, the four 60Hz panels each give up nothing that matters and each offer something the faster panels do not. The PA27JCV has the 218 pixel-per-inch 5K panel and a built-in Auto KVM. The PA32UCXR has the tightest Delta E and the only DisplayHDR 1400 tier here. The SW272U has hardware calibration with a bundled Hotkey Puck G3 controller, Palette Master Ultimate software and an SD card reader. The U2723QE pairs 163 pixel-per-inch 4K with a 90W USB-C hub and 1GbE Ethernet.
The 60Hz choice stops being enough the moment fast-motion games enter the picture. The PA32UCXR’s 40 to 60Hz Adaptive-Sync range is the only sync mode among the four, and it does not raise the ceiling.
The connectivity line that decides a two-computer desk
Because the panel figures cluster, hub features often make the actual decision. Four picks publish a KVM switch: the U3225QE, the U2724DE’s Auto KVM, the PA27JCV’s Auto KVM and the SW272U. Power delivery over the upstream cable ranges from 90W on the U2723QE, U2724DE, PA32UCXR, SW272U and PG32UCDM3, through 96W on the PA27JCV and PA278CFRV, to 140W on the U3225QE’s Thunderbolt 4 input. Wired networking appears on three: 2.5GbE on the U3225QE and U2724DE, 1GbE on the U2723QE. For fast external storage off the hub, the U3225QE carries a Thunderbolt 4 downstream port, the U2724DE publishes Thunderbolt 4 daisy-chaining and the PA32UCXR has two Thunderbolt 4 ports with daisy-chaining; which bus speed an external SSD actually needs is a separate decision.
Built-in speakers are published on three: the PA27JCV, the PA278CFRV and the PA32UCXR.
