If you prioritize HDR gaming and media consumption with high brightness and contrast, and are willing to invest in premium price, the CoolerMaster GP27U is an excellent choice. However, if digital photo editing is important to you and you prefer to save some money, the Dell U2723QE offers great color accuracy and would cost less. The CoolerMaster offers better performance for casual and competitive gaming due to its higher refresh rate and variable refresh rate support. On the other hand, for general productivity tasks such as text clarity and image editing, the Dell is very capable and offers more USB ports for connectivity. Give Feedback
