If you're a competitive gamer looking for a budget-friendly option, the AOC 24G2SPU, with its higher refresh rate and very good response time, provides smooth gameplay but has a lower resolution and is not ideal for HDR gaming or media. The Dell Alienware AW3821DW offers a larger screen size, wider resolution with better image clarity for productivity, and suitable brightness for HDR content, but it comes at a premium price and has a lower refresh rate which may not be the best for fast-paced gaming. If your focus is casual gaming and general productivity, the AOC 24G2SPU should suffice, while the Alienware monitor is better for a wider screen experience and consuming media in HDR. Give Feedback
