Both the P2510HS and the P2510S Plus share the same 24.5″ IPS panel with 1ms response time, identical 178°/178° viewing angles, and a glossy finish — so the panel technology baseline is equivalent. The real divergence lies in two opposing trade-offs: resolution versus refresh rate. The P2510HS runs at 1920 x 1080 with a 300Hz refresh rate, while the P2510S Plus steps up to 2560 x 1440 at 240Hz. Neither compromise is trivial.
The resolution gap translates directly into sharpness: at 89 ppi the P2510HS is noticeably softer, while the P2510S Plus at 119 ppi delivers meaningfully crisper text and finer image detail on the same screen size. Conversely, 300Hz gives the P2510HS a tangible edge in motion clarity for competitive gaming — though the practical difference between 240Hz and 300Hz is far subtler than the jump from, say, 144Hz to 240Hz, and most users would struggle to perceive it in day-to-day play. On adaptive sync, the P2510HS uses AMD FreeSync, limiting variable refresh rate support to AMD GPUs, while the P2510S Plus carries VESA Adaptive Sync, a more broadly compatible standard.
The edge here belongs to the P2510S Plus for most users. The jump to 1440p is a substantial, always-visible improvement in image quality, and 240Hz remains well above the threshold where diminishing returns set in. The P2510HS makes sense only for competitive players who are GPU-locked to AMD hardware and for whom every single Hertz of refresh rate is a priority over visual fidelity.
