Warranty: 1 Year ProArt Display OLED series features an ASUS OLED Care with three functions: (1) Panel Protection (2) Image Protection and (3) Proximity Sensor, all designed to protect your OLED display and minimize the risk of image burn-in. However, it's important to note that overly strong protection settings may impact image quality. To balance this, different protection levels are provided. For example, the default setting (Level 1) is optimized to provide OLED burn-in protection while minimizing impact on image quality, making it ideal for most creative workflows. You can also adjust the protection levels individually to suit your preferences. - Why is my screen showing a black image while the indicator light flashes white? This is the ongoing Off Sensing process designed to protect the OLED panel. The Off Sensing feature is part of the Panel Protection function and operates based on different time settings: Off (12 hours), Level 1 (8 hours, default), and Level 2 (4 hours). The timer counts down whether the screen is on or in standby mode. Once the set time is reached, the monitor will display a warning message and then automatically begin the Off Sensing process. During this process, the screen will turn black, and the indicator light will flash white for approximately 6 minutes. You can cancel the Off Sensing process by pressing the power button on the monitor. Additionally, Off Sensing will also automatically activate in standby and power-off modes. 31.5-inch 4K UHD (3840 x 2160) QD-OLED panel with 240 Hz refresh rate and 0.1 ms (GTG) response time for smooth rendering 1000 nits peak brightness with VESA DisplayHDR™ True Black 400 for exceptional color contrast True 10-bit color depth and Quantum Dot technology provide 100% sRGB, 99% DCI-P3 and BT. 2020 color gamut World-leading E < 1 color performance and ASUS ProArt Hardware Calibration Technology for color-accuracy optimization and color profile write-back Multiple HDR format support, including Dolby Vision ®, HLG and HDR10 Rich connectivity including dual Thunderbolt™ 4 up to 96W Power Delivery with daisy-chaining, HDMI2.1 and a built-in USB Hub Ergonomic design with tilt, pivot and height adjustments for a comfortable viewing experience Green Sustainability: paper packaging and energy-efficient environmental standards
