LG is preparing a 1500-nit 39-inch 5K curved monitor that's almost as bright as Apple's Pro Display XDR — but at a fraction of the price

- LG Display’s 39-inch 5K ultrawide uses a 5120 x 2160 resolution panel
- The WOLED panel carries DisplayHDR True Black 500 certification
- LG Display confirms a true RGB stripe subpixel layout on the 39-inch panel
LG Display is preparing a 39-inch curved ultrawide monitor with a 5K2K resolution of 5120 x 2160 pixels, placing it within the current 5K monitor class.
At this size, the display delivers an estimated pixel density of around 142ppi, which matches closely with existing 31.5-inch 4K monitors rather than introducing a clear jump in sharpness.
LG Display has confirmed that this business monitor uses its Tandem WOLED architecture, previously referred to as fourth-generation Primary RGB Tandem.
Brightness targets and panel technology
The display reaches peak brightness levels of up to 1500 nits at a small average picture level, which puts it close to reference-class models such as Apple’s Pro Display XDR.
The panel is expected to carry DisplayHDR True Black 500 certification and use a true RGB stripe subpixel layout, which affects text rendering and color reproduction on desktop displays.
LG Display has not formally detailed the mechanical specifications, but the presentation points to a gentler curvature than the 800R designs used on its earlier 34-inch and 39-inch ultrawide panels.
A reduced curve would affect desk ergonomics and viewing comfort, particularly at this screen width, although LG Display has not confirmed the final radius.
