If high-quality HDR gaming and media consumption are top priorities, and budget is less of a concern, the CoolerMaster GP27U with its excellent color reproduction and higher brightness levels would be a solid investment. This monitor also offers superior performance in environments with varying light conditions due to its MiniLED technology. However, if your focus is on tasks like digital photo editing that demand accurate colors, and you're looking for a more cost-effective option with still great image clarity, the Dell S2721QS would be a suitable choice, especially if gaming and media consumption are more casual pursuits for you.

"The Dell S2721QS 4K monitor brings IPS-level colors and some handy features, like a versatile stand with height adjustments and picture-in-picture for connecting dual systems. But don’t get it for HDR."
