Overview
Size and speed rarely arrive together, which is what the Asus ROG Swift OLED PG32UCDP is selling: a 31.5-inch LG Display OLED at 4K. The 31.5-inch LG Display OLED panel lists 0.03 ms GtG response, 99% DCI-P3, 100% sRGB and 10-bit colour. FreeSync Premium Pro and G-Sync Compatible support variable refresh from 24 Hz to 240 Hz. Typical brightness is 250 cd/m² against a 1,300 cd/m² peak claim, so sustained full-screen output will be far lower than the peak figure. Driving 4K at high frame rates remains one of the hardest targets in PC gaming, so budget for a flagship card alongside it. Buy it if 4K OLED, 240 Hz and 90 W USB-C fit your desk; skip it if portrait rotation, speakers or complete port documentation are essential.

HDR & Brightness Reality
The self-emissive OLED (LG Display) panel gives the DisplayHDR 400 True Black / HDR10 badge a stronger basis than a basic edge-lit LCD. The sheet lists 1300 cd/m² peak brightness and ∞ : 1 (OLED) contrast, but typical brightness is only 250 cd/m². That large gap means the peak should be treated as a highlight claim, not constant full-screen output. No test-window size or sustained-brightness result is published.

Frequently Asked Questions
01 Why pair 3840 x 2160 with 24 Hz - 240 Hz on the ROG Swift OLED PG32UCDP? +
The range is listed as 24 Hz - 240 Hz, so the upper end is aimed at high-frame-rate use. A high-end GPU is advisable for 4K at high frame rates.
02 What does the ROG Swift OLED PG32UCDP's 0.03 ms GtG claim leave unanswered? +
The published value is 0.03 ms (GtG), which is a manufacturer specification. The sheet does not show overshoot, settings, sustained behaviour or independent measurements.
03 How meaningful is DisplayHDR 400 True Black / HDR10 on the ROG Swift OLED PG32UCDP with 250 cd/m² typical and 1300 cd/m² peak brightness? +
The peak is above the typical figure, but it should not be treated as constant full-screen output. The sheet gives no test-window size or sustained-brightness result.
04 How much of a desk setup can the ROG Swift OLED PG32UCDP's 90 W USB-C connection replace? +
The sheet lists DisplayPort Alt Mode, data and up to 90 W power through USB-C. A compatible laptop may use one cable, although its own power requirement still decides whether 90 W is sufficient.
05 What stand compromise remains on the ROG Swift OLED PG32UCDP despite its other adjustments? +
Height adjustment is 110 mm and swivel is ±15°, but pivot is listed as No. Portrait orientation would require a compatible 100 x 100 mm arm.
