Overview
Uncompromising speed defines the Asus ROG Swift OLED PG27UCWM, a 26.5-inch QD-OLED gaming monitor that switches between 4K at 240 Hz and Full HD at 480 Hz on demand. Its Samsung QD-OLED panel delivers 165 PPI, 99% DCI-P3 and true per-pixel blacks, while 0.03 ms GtG response and both FreeSync Premium Pro and G-Sync Compatible certification keep motion clean whichever GPU is driving it. DisplayPort 2.1 (UHBR20) and HDMI 2.1 carry the full 240 Hz signal without compression, and a 90 W USB-C port turns it into a single-cable laptop dock alongside three USB-A ports. Its case for skipping it is narrow: no speakers, no camera, and DisplayHDR 400 True Black is a modest peak-brightness tier for a panel this capable elsewhere. Buy it if dual-mode 4K/240Hz and FHD/480Hz speed on one screen matters more than built-in audio or blazing HDR highlights.
Key Highlights
- Dual-mode panel switches between native 4K at 240 Hz and Full HD at 480 Hz
- 0.03 ms GtG response time - among the fastest pixel transitions published on any monitor
- Both AMD FreeSync Premium Pro and NVIDIA G-Sync Compatible certified
- DisplayPort 2.1 with UHBR20 bandwidth carries 4K at 240 Hz uncompressed
- 90 W USB-C powers a laptop through the same cable that carries video and data

HDR & Brightness Reality
DisplayHDR 400 True Black is the certification here, and on an OLED panel the "True Black" designation matters more than the 400 number: it confirms near-zero black levels rather than judging HDR purely on peak brightness. At 1000 cd/m2 peak, highlights are respectable but well short of what mini-LED or higher OLED tiers (like DisplayHDR 1000) can hit. HDR10 and Dolby Vision are both supported for format compatibility with the widest range of streaming and gaming HDR content. In practice this means excellent contrast in dark scenes - true blacks next to bright highlights - but it will not deliver the blinding specular highlights a brighter panel can.

DisplayHDR 400 True Black, HDR10, Dolby Vision - the True Black tier confirms genuine OLED blacks but caps peak brightness lower than higher HDR tiers; format support is broad even if brightness headroom is modest. |

| Peak Brightness | 1000 cd/m² | |
| Contrast | 1500000 : 1 | 1,500,000 : 1 - a marketing figure typical of OLED panels with true per-pixel blacks; in practice the panel simply turns off dark pixels entirely, so real-world contrast is effectively unlimited rather than a meaningful ratio to compare against LCDs. |
