Quick Answer: The ASUS ROG Swift OLED PG27UCDM is still the 27-inch 4K QD-OLED to beat in 2026: a 26.5-inch 4K 240Hz QD-OLED that RTINGS measured at 317 nits in an SDR real scene, against 216 for the Alienware AW2725Q and 239 for the MSI MPG 272URX, with DisplayPort 2.1a, Dolby Vision and a 3-year burn-in-inclusive warranty. It lists at $1,099 on ASUSâs US eShop but sold for $949 at Amazon on October 30, 2026. Buy it near $950; at full list, the $899.99 AW2725Q is the better value, and console players who game at 60 fps should note its 14.8 ms 60Hz input lag.
This site cites the PG27UCDM in seven different guides, from the best ASUS monitor ranking to the best monitor for PS5 Pro, but it has never had its own review. This one is built on published lab measurements rather than impressions: RTINGS, TFTCentral, Tomâs Hardware, PCWorld and Hardware Unboxed have all instrument-tested it, so every number below names the lab that produced it. It matters because ASUS now sells three other 27-inch 4K OLEDs with near-identical model numbers, and none of them is simply a cheaper version of this one.

ASUS ROG Swift OLED PG27UCDM
- Brightest SDR image of the 27-inch 4K QD-OLEDs RTINGS has compared it with: 317 nits real-scene, 444 nits on a 2% window.
- Total response time 0.4 ms at 240Hz and 2.7 ms input lag at 240Hz, per RTINGS.
- DisplayPort 2.1a UHBR20 runs 4K 240Hz without compression; Dolby Vision, KVM switch and 90W USB-C on top.
- Tom's Hardware: 5/5 and Editor's Choice; PCWorld: 4/5 and Editors' Choice.
ASUS launched the PG27UCDM at $1,099 in January 2025, and Amazon briefly pushed it as high as $1,299 in March 2025, per camelcamelcamelâs history. Through 2026 it has mostly sold under list: camelcamelcamel records a $934 Amazon low on June 24, 2026, and Amazon showed $949 on October 30, 2026, while ASUSâs own eShop still charged the full $1,099. Treat $950 as the price to wait for.
What the labs measured
| Test | Result | Lab |
|---|---|---|
| SDR real-scene brightness | 317 nits (255 with Uniform Brightness on) | RTINGS |
| SDR peak / full white | 465 nits / 260 nits | TFTCentral |
| HDR peak (small window) | 1,016 nits on 2% (RTINGS), 1,012 nits on 1% in Console mode (TFTCentral) | RTINGS, TFTCentral |
| HDR real-scene brightness | 412 nits | RTINGS |
| Dolby Vision peak | About 456 nits in every Dolby Vision mode (deliberate, per ASUS) | TFTCentral |
| Total response time | 0.4 ms at 240Hz and 120Hz, 0.3 ms at 60Hz | RTINGS |
| Input lag | 2.7 ms at 240Hz, 5.1 ms at 120Hz, 14.8 ms at 60Hz | RTINGS |
| Color accuracy out of the box | Delta E 1.13 (sRGB Cal mode); 0.59 average error | RTINGS; PCWorld |
| Gamut | 99.4% DCI-P3, 77.3% Rec.2020 | RTINGS |
| Black level at 1,000 lux | 2.50 nits, with a purple tint | RTINGS |
| Uniformity | 5.01% deviation, best in its test group | Tom's Hardware |
| Power draw | 73.3 W at calibrated 200 nits full white | Hardware Unboxed (via TechSpot) |
The brightness lead needs one qualifier. The PG27UCDM is brighter than its rivals on mixed content and small windows, such as dark-mode apps or a game HUD, but at full white every 27-inch 4K QD-OLED lands in the same place: Hardware Unboxed measured 255 nits for the PG27UCDM, 255 for the MSI MPG 272URX and 250 for the AW2725Q. PCWorldâs full-field SDR test likewise found 268 nits against 269 for the MSI. Choose it for punchier everyday SDR, not for a brighter white spreadsheet.
The more useful lab finding is accuracy. RTINGS measured a color Delta E of 1.13 before calibration, and PCWorld recorded a 0.59 average color error, the best of the five OLEDs in its comparison. For a gaming monitor, that is close to calibrated-out-of-the-box behavior.
PG27UCDM vs the 27-inch 4K OLED rivals
| RTINGS measurement | ASUS PG27UCDM | Alienware AW2725Q | MSI MPG 272URX | Samsung Odyssey OLED G8 G81SF |
|---|---|---|---|---|
| SDR real-scene brightness | 317 nits | 216 nits | 239 nits | 252 nits |
| HDR real-scene brightness | 412 nits | 366 nits | 417 nits | 427 nits |
| Input lag at 60Hz | 14.8 ms | 9.6 ms | 9.8 ms | 9.8 ms |
| Screen finish | Semi-glossy (18.1% direct reflection) | Not in RTINGS' comparison | Glossy (29.1% direct reflection) | Matte (6.0% direct reflection) |
| Price, October 30, 2026 | $949 Amazon, $1,099 ASUS | $899.99 Dell.com | $899.99 MSI store / Best Buy | $999.99 Samsung.com (out of stock) |
RTINGSâ head-to-head verdicts are consistent: the ASUS gets brighter, handles glare better than the MSI and tracks HDR brightness more closely than the Dell, and its KVM switch and 90W USB-C make it the better productivity monitor than the Samsung. Hardware Unboxed reached the same split in its written AW2725Q review on TechSpot: the PG27UCDM âremains the best model overallâ, but with the ASUS costing about 20% more, the Dell is the better value. Samsungâs G81SF has also been the deal-day wildcard, hitting $664.99 in an Amazon lightning deal on October 7, 2026, per Tomâs Hardwareâs Prime Day live blog.
The weak spots
- 60Hz input lag. RTINGS measured 14.8 ms at 60Hz, which it called slightly higher than expected, against 9.6-9.8 ms for the Dell, MSI and Samsung. It is irrelevant at 120Hz and above (5.1 ms), but it is the one number that favors the rivals for 60 fps console games.
- Raised blacks in a bright room. Like every QD-OLED, the panel has no polarizer. RTINGS measured black rising to 2.50 nits at 1,000 lux with a purple cast, and contrast falling to 81:1; TFTCentral rated ambient-light handling âPoorâ. In a dim room, contrast is effectively infinite.
- VRR flicker, made worse by the fix. RTINGS scored VRR flicker 5.7/10 and found that ASUSâs OLED Anti-Flicker setting increased dark-gray flicker (33.1 RGB on Middle versus 4.8 off). TFTCentral also saw the least flicker with the setting off.
- Dolby Vision is dimmer than HDR10. All Dolby Vision modes cap out at about 456 nits, against 1,012 nits in HDR10 Console mode, per TFTCentral. TechRadar also found Dolby Vision made the screen blank briefly when switching between programs.
- Black frame insertion is limited. ELMB works only at a fixed 120Hz, in SDR, without VRR, and at a maximum of 134 nits, per TFTCentral.
- A Mac quirk. RTINGS found that M2-or-newer Macs over USB-C need the monitorâs USB-C setting on âUSB 2.0â to reach 240Hz.
Three ASUS lookalikes: which 27-inch 4K OLED is which
| Model | Panel | DisplayPort | Dolby Vision | USB-C | US price, October 30, 2026 |
|---|---|---|---|---|---|
| ROG Swift PG27UCDM (reviewed) | 26.5" 4K 240Hz QD-OLED | 2.1a UHBR20 | Yes | 90W | $1,099 ASUS, $949 Amazon |
| ROG Strix XG27UCDMG | Same 26.5" 4K 240Hz QD-OLED | 1.4 with DSC | No (HDR10) | 90W | $899 ASUS (out of stock); $799.99 Amazon low, June 2026 |
| ROG Strix XG27UQDMS | 26.5" 4K 240Hz QD-OLED | 1.4 with DSC | No (HDR10) | None | No US price listed (UK pre-order ÂŁ738.98) |
| ROG Swift PG27UCWM | 26.5" Tandem RGB-stripe WOLED, 4K 240Hz or 1080p 480Hz, glossy | 2.1a UHBR20 | Yes | 90W | $1,199 ASUS (out of stock) |
- XG27UCDMG: same panel, fewer extras. The Strix model uses the same QD-OLED panel and keeps 90W USB-C, but drops to DisplayPort 1.4 with compression and loses Dolby Vision, per ASUSâs spec page and TFTCentral. Windows Central reported it at $799.99 on Amazon in June 2026. If you game on PC with HDR10 content only, it is the cheaper buy whenever it is in stock.
- XG27UQDMS: the stripped-down 2026 Strix. No USB-C, two USB-A ports, HDR10 only and DisplayPort 1.4 with DSC. ASUS and Notebookcheck disagree on whether its panel is the newer tandem stack, so check reviews before buying it as a PG27UCDM substitute.
- PG27UCWM: a different technology, not a refresh. The 2026 Swift swaps Samsung QD-OLED for an RGB-stripe tandem WOLED panel with a glossy coating and a 1080p 480Hz mode. Tomâs Hardwareâs September 2026 review found it slightly sharper and called the PG27UCDM âlast yearâsâ model, but at $1,199 and out of stock at ASUS, it costs $250 more than the PG27UCDMâs Amazon price. For the panel trade-offs, see our QD-OLED vs WOLED explainer.
Update the firmware first
ASUS has shipped six firmware updates since launch, per its US support page, and several fix bugs early reviewers ran into. Check the OSD version before judging your unit.
| Firmware | Released | Main changes |
|---|---|---|
| MCM102 | April 1, 2025 | Proximity sensor fixes, ASUS PowerSync for Xbox, PlayStation and Apple TV |
| MCM103 | May 12, 2025 | Fixed a brightness drop with HDR on AMD GPUs |
| MCM104 | July 8, 2025 | Fixed PiP/PbP after Dolby Vision, USB hub in standby |
| MCM105 | August 29, 2025 | Fixed DSC not turning off under UHBR20 |
| MCM107 | December 9, 2025 | Proximity sensor range up to 120 cm; auto pixel cleaning after 3 minutes in standby |
| MCM108 | January 14, 2026 | Anti-Flicker setting kept across inputs; several Dolby Vision fixes |
The MCM105 fix matters for anyone who bought the PG27UCDM for its DisplayPort 2.1a port: before it, DSC could stay on even over a UHBR20 link, and with DSC active, TFTCentral notes, NVIDIA DSR and DLDSR are unavailable.
Warranty and burn-in
ASUSâs US spec page lists the PG27UCDM warranty as 3 years, including panel burn-in, and the model is not on ASUSâs US list of OLED monitors limited to 24 months (that list includes the PG27AQDM, PG34WCDM, PG42UQ and PG49WCD). ASUSâs support FAQ, updated in October 2026, says a box or card printed with âtwo-year warrantyâ is still covered for three. ASUS does not publish written conditions for burn-in claims, so leave pixel cleaning and the proximity sensor on; our OLED burn-in guide covers the habits that matter. A search of the CPSC recall database found no recall for the PG27UCDM or any ASUS monitor.
Who should buy the PG27UCDM
- Buy it if you game on a PC, want the brightest everyday SDR picture of the 27-inch 4K QD-OLEDs, and can use DisplayPort 2.1a, Dolby Vision or a single-cable USB-C laptop dock.
- Buy the Alienware AW2725Q instead if price comes first and you play console games at 60 fps: it costs $899.99 at Dell.com and has 5 ms less 60Hz input lag in RTINGSâ testing. Our Dell vs ASUS monitor comparison covers the brand trade-offs.
- Buy the XG27UCDMG instead if you only need HDR10 and DisplayPort 1.4 is fine: same panel, $799.99-899.
- Wait if you specifically want an RGB-stripe panel for sharper text: the PG27UCWM fixes that, at $1,199 when it is in stock.
- Skip it if your desk faces a window: the Samsung G81SFâs matte coating (6.0% direct reflection) handles direct glare better, even though it also has QD-OLEDâs raised blacks.
PG27UCDM by the numbers
- 317 vs 216 nits. The PG27UCDMâs SDR real-scene brightness versus the Alienware AW2725Qâs, per RTINGS, a 47% lead.
- $934. Its lowest Amazon price, on June 24, 2026, per camelcamelcamel, against the $1,099 list.
- 14.8 ms. RTINGSâ 60Hz input lag, about 5 ms more than the Dell, MSI and Samsung rivals.
- 456 nits. TFTCentralâs Dolby Vision ceiling, versus 1,012 nits in HDR10 Console mode.
- 3 years. ASUSâs US warranty, including burn-in.
- 6. Firmware updates ASUS has released, from MCM102 in April 2025 to MCM108 in January 2026.
The bottom line
The ASUS ROG Swift OLED PG27UCDM is the 27-inch 4K QD-OLED to buy when you want the best image rather than the best price: lab-leading SDR brightness, near-calibrated color out of the box, DisplayPort 2.1a, Dolby Vision and a 3-year burn-in warranty. It is worth it at the $934-949 it has been selling for on Amazon; at the full $1,099, the $899.99 Alienware AW2725Q is the better value. It remains the top pick in our best ASUS monitor ranking and the HDR pick in our best monitor for PS5 Pro guide.
