What reviewers say about the ASUS ROG Swift OLED PG27UCDM
Four whitelisted testers (Tom's Hardware, PCWorld, TechPowerUp, TechRadar) rate this 27-inch 4K 240Hz QD-OLED among the best OLED gaming monitors, praising deep OLED blacks, out-of-box color accuracy and near-instant pixel response. Tom's Hardware and PCWorld single out its class-leading ~161-163ppi sharpness, while PCWorld and TechRadar fault the roughly $1,100 price and oversized tripod stand. TechPowerUp's tested page confirms sub-1ms response and ~2ms input lag but flags ELMB's heavy limitations.

Commonly flagged
- Expensive for a 27-inch panel; weak value versus larger/cheaper rivals · 2 sources
- Oversized tripod stand eats too much desk space and pushes the panel close · 2 sources
- No built-in speakers · 2 sources
- Modest full-screen SDR brightness (well under 300 nits)
Where reviewers disagree Testers split on whether the premium price is justified: Tom's Hardware names it an Editor's Choice and 'could find nothing to complain about,' viewing the price as warranted by unmatched 163ppi sharpness, while TechRadar calls the value prospect poor and the ROG styling/stand 'overkill.' PCWorld sits in between, noting image quality is essentially identical to cheaper competing QD-OLEDs.
The sources (4)
peak brightness (25% window): 465 nits
Accuracy is excellent right out of the box with no need for calibration and a pro-level sRGB mode.
If you want the very best OLED technology has to offer, the Asus ROG Swift PG27UCDM should be on your short list.
No internal speakers
sRGB gamut coverage: 100% · DCI-P3 gamut coverage: 98% · AdobeRGB gamut coverage: 92% · measured color temperature (set to 6500K): 6300K · measured gamma (set to 2.2): 2.3
Color accuracy finally gives Asus a clear win.
The result is a sharp, vivid image that looks gorgeous in a wide range of SDR content.
we're still talking well under 300 nits at its maximum brightness
average initial response time: 0.93 ms · complete transition time: 1.64 ms · average perceived response time: 1.18 ms · rise time: 1.31 ms · fall time: 1.04 ms · on-display input lag (average): ~2 ms
The on-display lag of the ASUS ROG Swift OLED PG27UCDM measures just about 2 ms on average, with a worst case slightly above 4.5 ms, which is an excellent result.
The measured average initial response time is just 0.93 ms, with a complete transition time of 1.64 ms and an average perceived time of 1.18 ms
ELMB comes with heavy limitations: it only works at 120 Hz, requires VRR to be disabled, disables HDR, and locks out brightness adjustment.
The panel performed exceptionally well in every game that I played
The technology is perfect but the execution is overkill, and the value prospect isn't very good.
Expensive, especially for a 27-inch panel
Specifications
| Price (US) | Not published No verifiable USD price. The fetched ASUS ROG spec page showed only an empty "ASUS estore price starting at" field with no figure, and the Newegg corroboration listed $919.99 (lowest, "in 30 days") through a "More options from $919.99 - $1,499.99" range rather than any single $1,099 MSRP. The originally cited "ASUS US e-store $1,099.00" page (rog.asus.com/us/...) was not the fetched URL and could not be confirmed; priceUsd left null pending a verifiable manufacturer price. |

Source: rog.asus.com (verified 2026-07-08) · corroborated by newegg.com. The ASUS ROG global spec page (source) confirmed verbatim: QD-OLED / Tandem QD-OLED panel, 3840x2160 resolution, 240Hz max refresh rate, 0.03ms (GTG) response time, VESA DisplayHDR 400 True Black certification (stored normalized to the catalog's "VESA DisplayHDR True Black 400" convention), and I/O of DisplayPort 2.1 x1 + HDMI v2.1 x2 (FRL) + USB-C x1 (DP Alt Mode) with 90W USB-C Power Delivery + USB hub of 3x USB 3.2 Gen 1 Type-A, plus VRR "FreeSync Premium Pro & G-SYNC Compatible" (also in the certificate list as "AMD FreeSync Premium Pro" and "G-SYNC Compatible"). The spec page lists Panel Size as 26.5-inch (viewable); size stored as the nominal 27, which is corroborated verbatim by the Newegg search-results listing showing 27" screen size, 3840x2160 (4K), 240Hz, 0.03ms, AMD FreeSync Premium & G-Sync Compatible, 1x DisplayPort 2.1a, 2x HDMI 2.1, 1x USB-C (DP Alternative), and 3x USB 3.2 Gen 1 Type-A. Adversarial checks removed three unsupported values: priceUsd $1,099 could not be found (source price field empty; Newegg range $919.99-$1,499.99), and the 2025 release year appears in neither fetched page, so releaseDate and specs.release were nulled. Model verified exact (PG27UCDM), not a sibling/variant.
