If competitive gaming is a high priority, the Acer X27U excels with features tailored to reduce ghosting and has a very good overall gaming performance. For digital photo editing or print photo editing, the ViewSonic VX2776 with its excellent color gamut coverage is a better fit, though the Acer still performs well in this area. Both are strong contenders for HDR gaming and media consumption, but if brightness is crucial, the Acer has an edge. For casual gaming or general productivity, both monitors will serve you well, but the Acer's additional USB ports could provide more connectivity options for peripherals. Give Feedback
