ProArt 27" 4K QD-OLED

The ASUS ProArt PA27USD is a 26.5-inch 4K UHD professional monitor built on a QD-OLED panel. It targets colour-critical workflows in video post, design and photography where reference-grade accuracy matters. A 240 Hz refresh rate and 0.1 ms GTG response also suit high-frame-rate preview work.

Integrated colorimeter and 12G SDI

An on-board motorised colorimeter enables self and auto calibration with profile write-back, keeping Delta E below 1 over time without external probes. The 12G SDI input carries 4K at 60 Hz uncompressed and remains compatible with 6G and 3G Level A and B signals for broadcast pipelines.

Thunderbolt 4 hub and ergonomic stand

Dual Thunderbolt 4 ports deliver up to 96 W power delivery while functioning as a USB 3.2 Gen 2 hub for peripherals. The stand provides height, tilt, swivel and pivot adjustment, and a 100 x 100 mm VESA pattern allows arm or wall mounting when desk space is limited.

Questions about this item

How often will the integrated colorimeter need to run self-calibration to keep Delta E below 1?

The built-in colorimeter handles self-calibration automatically; no user schedule is required to maintain factory-verified accuracy.

What brightness ceiling appears first during a full-day HDR grading session?

Sustained full-screen output is rated at 250 cd/m2, while 1000 nits peak is only available for small highlight areas.

How loud do the cooling fans get after eight hours at 240 Hz?

The monitor runs fanless; total power draw stays under 32 W so heat is dissipated silently through the chassis.
