In the system settings, the “Uniform Brightness” feature is set to ‘off’ as the default in standard mode. This setting lets the OLED panel exhibit optimal contrast, fully showcasing the nuances of both light and dark details via dynamic backlighting. However, during operations in Windows, if there’s a transition from an entirely dark screen to one that’s partially or wholly bright, the changes in dynamic backlight can feel a bit jarring to users due to the shifts in brightness. Activating the uniform brightness ensures the panel retains a consistent brightness level, but this comes at the cost of the OLED’s inherent advantage of high dynamic contrast.

The PA27DCE-K is equipped with an ambient light sensor, which is why there’s an “Ambient Light Source Change” option in its settings. Activating this feature will adjust the screen’s brightness in response to the surrounding ambient light, while the adaptive color modifies the color temperature to align with the environment.

However, realistically speaking, the light sources in most office settings remain constant, possessing a specific brightness and color temperature. For professionals requiring color precision, it’s imperative that the brightness and color temperature of their workspace remain consistent. Moreover, placing the screen where it might receive direct sunlight is not ideal. Thus, it’s advisable to keep this feature turned off.

The PA27DCE-K comes with a “proximity sensor” feature. When activated, the screen autonomously detects if there’s an object within a distance of 30cm to 1.5m. If no object is identified, the screen dims its brightness automatically. This feature aids in prolonging the lifespan of the OLED panel. If the screen isn’t going to be used for extended periods, it’s also advisable to configure the system to turn off the display after 3-5 minutes of inactivity.

The “screen saver” feature, which isn’t activated by default, is designed with the understanding that professional users might often fix their gaze on the screen for detailed observation. When enabled, this function dims the screen’s brightness to safeguard the panel. However, it could potentially interfere with the requirements of professionals. Users should adjust this function based on their individual usage patterns.


The X-rite i1 Display Pro color corrector

The PA27DCE-K is pre-calibrated before it’s shipped from the factory. Included in its accessories is an X-rite i1 Display Pro color corrector. This tool can be paired with the i1Profiler software to calibrate the screen’s color and integrate the ICC color profile into the system. Users can also set regular reminders to undertake color correction procedures. This ensures that even as the panel undergoes gradual changes over time, it maintains an accurate color performance with a Delta E value of less than 1.

The ProArt Display OLED PA27DCE-K boasts a 26.9-inch, 4K OLED panel with a resolution of 3840 x 2160. With its RGB layout, this OLED panel delivers exceptionally intricate visuals. Right out of the box, having been pre-calibrated at the factory, it exhibits color gamut performances of 100% sRGB, 99% Adobe RGB, 99% DCI-P3, and 90% Rec.2020, achieving an impressive average color accuracy of △E<1.

The inherent self-illuminating nature of the OLED panel, combined with dynamic backlighting, provides a remarkably high contrast ratio, rendering colors uniformly vibrant. Unlike IPS panels which necessitate high brightness for vivid color representation, OLEDs showcase superior color gradation even in darker areas, making them ideal for editing HDR high dynamic range imagery.

However, there’s room for improvement. This OLED panel’s native refresh rate caps at 60Hz. Even though OLEDs have a swift 0.1ms (GTG) response time, the portrayal of rapid dynamic visuals can appear slightly blurred. It’s clear that while one avenue of perfection was achieved with “Accurate Color”, certain dynamic capabilities were slightly compromised. Hence, the PA27DCE-K might best serve purposes that lean more towards static visuals, 2D imaging, and 3D production, especially tasks demanding pinpoint color accuracy.

Contrarily, I appreciate the PA27DCE-K’s use of an RGB arrangement on its OLED panel. With the display set to a resolution of 2160p and a 100% zoom in Windows, I find clarity even at half a meter’s distance from the screen – filenames and folder names are easily discernible and are of a comfortable size for operation.

Priced at NT$ 46,900 in Taiwan, the ProArt Display OLED PA27DCE-K is a solid investment. For those who prioritize color accuracy, this device is certain to impress.
