MSI showcases its 27" 4K monitor that uses TCL CSOT's inkjet printed panel

As TCL CSOT begins to commercially produce inkjet printed OLED panels at the company's 5.5-Gen line, MSI announced the first product to use one of these panels - the premium MSI Pro Max OLED 271UPJW12, based on a 27" 4K (164 PPI) 120Hz and Real RGB Stripe side-by-side subpixel structure. The monitor integrates MSI's OLED Auto Care Compensation Technology, to mitigate burn-in.

Today, at the ChinaJoy tradeshow in China, MSI demonstrated this panel, and a reviewer posted a video where they tested the new display and revealed several interesting specifications.

 

This is for a demo unit, of course, and the reviewer confirmed a peak brightness of 584 nits (SDR), or 330 nits at 100% full white SDR, and a peak brightness of 1041 nits (1% HDR). The reviewer also shows the monitor's low-reflectivity matte finish (reflectivity SCI 1.7%, SCE 0.7%).
