During the ChinaJoy 2026 event, TCL CSOT and MSI jointly unveiled the world’s first 27” 4K 120Hz Inkjet-printed (IJP) OLED high-end professional desktop monitor. The new display leverages IJP OLED technology to usher in the next generation of professional displays for office work, content creation and multimedia entertainment.
This launch marks TCL CSOT’s debut into the mid-size IJP desktop monitor segment for consumer applications.
World’s first 27” 4K 120Hz IJP OLED high-end professional desktop monitor
MSI Pro Max OLED 271UPJW12 is powered by TCL CSOT’s IJP OLED display solution, and features a 27-inch 4K 120Hz panel with vertical RGB stripe pixel arrangement. This architecture eliminates color fringing around text and image edges to deliver pixel-sharp text clarity.
Color performance is impressive with 99% DCI-P3 wide color gamut coverage, Delta E ≤ 2 color accuracy, and VESA DisplayHDR True Black 500 certification. With 1,000 nits HDR peak brightness and OLED’s inherent infinite contrast ratio, the display delivers deep, pure blacks and well-defined, richly detailed highlights. 164ppi pixel density meanwhile ensures exceptional sharpness for both color-critical creative workflows and immersive visual entertainment.
The monitor introduces MSI’s OLED Auto Care full-time protection technology, a pioneering invisible background maintenance system and the world’s first uninterrupted OLED protection on a monitor. Supporting real-time Data Counting Compensation (DCC), the new solution eliminates disruptions caused by traditional forced protection mechanisms. The result is a zero-pop-up and interruption-free experience.
The monitor also streamlines multi-device setups with an integrated KVM switch, PIP/PBP models, and a USB-C interface with 15W Power Delivery. An ergonomic stand with height, tilt, swivel, and pivot adjustment further allows users to create comfortable workspaces tailored to different applications.
The IJP OLED panel has earned Eyesafe 3.0 certification for natively limiting harmful blue light emissions to 20% or below and also meets the Circadian Protection Factor (CPF) standard designed to reduce the impact of nighttime screen use on sleep patterns. At the system level, the PRO MAX OLED 271UPJW12 features hardware-level TUV-certified low blue light and flicker-free, ensuring visual comfort throughout extended use.
The panel incorporates an upgraded anti-glare (AG) coating that increases surface hardness from 2H to 3H, boasting scratch resistance by up to 2.5x while minimising glare and reflections. Robust multi-format support across SDR and HDR modes enables highly customisable display settings, tailored for every scenario.
