Display Panel Technology and Contrast
The starkest difference in this Dell S2725QS vs LG 32GX870A matchup lies within their core display technologies. The LG 32GX870A uses a cutting-edge OLED panel enhanced with Micro Lens Array+ (MLA+) technology. Because OLED pixels are self-emissive, each individual subpixel turns off completely when rendering black scenes. This allows the display to achieve a staggering 1,500,000:1 contrast ratio alongside certified VESA DisplayHDR True Black 400 performance. Shadow detail in dark video games or atmospheric movies appears pristine, without any backlight bleed or haloing around bright UI elements. The MLA+ optical layer also focuses light output, allowing small specular highlights to reach up to 1300 nits while maintaining a typical full-screen brightness of 275 nits.
By comparison, the Dell S2725QS employs an in-plane switching (IPS) panel with a traditional LED backlight. While standard IPS screens often settle around a 1000:1 contrast ratio, the S2725QS pushes static contrast up to 1500:1, delivering solid dynamic depth for an edge-lit desktop screen. It covers 99% of the sRGB color space and reaches a uniform 350 nits of brightness across the screen. While its HDR readiness adds compatibility for high-dynamic-range signals, it cannot emulate the individual pixel illumination of an OLED panel.
