At ChinaJoy 2026, display manufacturer TCL CSOT and computing hardware brand MSI jointly unveiled the PRO MAX OLED 271UPJW12, introduced as the world’s first 27-inch 4K 120Hz Inkjet-Printed (IJP) OLED high-end professional desktop monitor.
The announcement marks TCL CSOT’s initial expansion into the mid-size consumer desktop display segment using IJP OLED technology, building upon its previous mass production of IJP OLED panels for medical equipment. Designed for office productivity, content creation, and entertainment, the monitor combines high pixel density with advanced panel manufacturing techniques.
Key Technical Specifications
The display offers a combination of high resolution, color accuracy, and dynamic range certifications tailored for professional workflows:
| Feature | Specification Details |
| Screen Size & Resolution | 27-inch 4K UHD |
| Refresh Rate & Pixel Density | 120Hz refresh rate, 164 PPI |
| Sub-Pixel Layout | Optimized RGB Stripe (reduces color fringing around text) |
| Color Gamut & Accuracy | 99% DCI-P3 coverage, Delta E ≤ 2 |
| HDR & Peak Brightness | VESA DisplayHDR True Black 500, up to 1,000 nits peak |
| Surface Coating | Anti-glare (AG) coating with 3H hardness rating |
Uninterrupted Protection and Eye Health Integration
To mitigate OLED degradation and burn-in without disrupting workflow, MSI introduced its MSI OLED Auto Care Technology. Rather than requiring users to pause operation for scheduled maintenance cycles, the monitor uses real-time Data Counting Compensation (DCC) operating in the background.
For ergonomic and ocular health, the display incorporates several certified protective measures:
- MSI EyesErgo Technology: TÜV-certified hardware for low blue light output and flicker-free operation.
- Eyesafe® 3.0 Certification: Natively limits harmful blue light emissions to 20% or less.
- Circadian Protection Factor (CPF) Compliance: Formulated to reduce exposure to specific light wavelengths that affect melatonin levels and sleep cycles.
Desktop Integration and Product Showcase
The PRO MAX OLED 271UPJW12 includes features focused on multi-device workflows, such as an integrated KVM switch, Picture-in-Picture (PIP) / Picture-by-Picture (PBP) modes, USB-C connectivity with 15W Power Delivery, and an adjustable ergonomic stand.
Alongside the primary monitor announcement, the joint TCL CSOT and MSI booth showcased several other 2026 gaming hardware devices:
- MSI Claw 8 EX AI+: A portable handheld console featuring an 8-inch WUXGA 120Hz display.
- MSI Raider 16 HX (2026): A gaming laptop equipped with a 16-inch WQHD 240Hz display.
- MSI Crosshair 18 HX (2026): A large-format gaming laptop featuring an 18-inch WQHD 240Hz panel.
The joint presentation highlights ongoing collaboration between panel maker TCL CSOT—utilizing technologies such as IJP OLED, HVA, and HFS—and MSI to deploy high-refresh and color-accurate display technologies across consumer hardware categories.
