If you prioritize high-end gaming with fluid motions and are looking for exceptional contrast and color depth, the Acer X27U with its OLED panel is an excellent option despite its higher cost. It presents strong performance in casual and competitive gaming, but note that it may not be the best for productivity tasks. Conversely, if your focus is on productivity, particularly if you deal with digital photo editing, the LG DualUp offers a unique screen with more vertical space and good color accuracy at a lower price, but it's not as well-suited for high-performance gaming or HDR video content.
