Refresh rate per resolution and portiHighest accepted rate for each proven resolution, input and operating condition. Preset or supported timing lists alone do not prove a maximum. Keep separate bit-depth, chroma and DSC conditions. Dual-mode or crop-mode requirements belong in source notes. Unknown input stays unknown.

Source2Maker product pagerog.asus.com/monitors/27-to-31-5-inches/rog-swift-oled-pg27ucwmRead 14 October 2026Feature page: DisplayPort 2.1a UHBR20 with full 80 Gbps supports 4K at 240 Hz without compression. Dual Mode switches between 4K at 240 Hz and FHD at 480 Hz. Maker spec page Signal Frequency gives 48 to 240 Hz vertical for HDMI, USB-C and DisplayPort at native resolution. The manual says Frame Rate Boost enables up to 1920 x 1080 at 480 Hz, and its timing table lists 3840 x 2160 at 240 Hz and 1920 x 1080 at 480 Hz as accepted on HDMI and on DP and USB-C. Bit depth, chroma and DSC for HDMI and USB-C are not stated. The manual's Type-C Bandwidth setting limits USB 3.2 mode to 3840 x 2160 at 120 Hz, so the USB-C maxima need the other bandwidth setting. HDMI 4K at 240 Hz needs a signal beyond uncompressed 48 Gbps, so no DSC value is stored for it.
