If you're a competitive gamer looking for a larger screen, the AOC AG456UCZD offers a high refresh rate and excellent performance for fast-paced games, while also being less expensive than the LG option. However, for digital photo editing or if high resolution is a priority, the LG 27EP950 has superior image clarity and is well-suited for media consumption, despite its higher cost. The AOC falls short in productivity and media consumption performance, whereas the LG might not satisfy the needs of competitive gaming as well as the AOC does. Choose the AOC if gaming and budget are priorities, or the LG for sharper images and professional creative work. Give Feedback
