If you prioritize high-resolution gaming and media with striking visuals and are willing to invest in a premium option, the CoolerMaster GP27U with its 4K resolution and superior HDR performance can enhance your experience. However, if your focus is on budget-friendly, responsive gameplay for competitive gaming, the Dell S2522HG with its higher refresh rate and lower resolution, which requires less powerful hardware to achieve higher frame rates, would be a sensible choice. Keep in mind, for tasks like digital photo editing or color-critical work, the CoolerMaster's wider color gamut and MiniLED technology offer advantages, while the Dell may fall short in image clarity due to its lower resolution and color performance.

"The Cooler Master Tempest GP27U leaves little to complain about. It delivers a stunning picture with high contrast, brightness, and vivid color. Professional-grade video processing means a superlative gaming experience. And it’s a little less expensive than the competition."

"The Dell S2522HG changes the game. This 24.5-inch 1080p gaming monitor has a 240Hz refresh rate, yet it’s commonly sold for $249.99. That’s just tens of dollars more than an average 1080p 144Hz gaming monitor. The S2522HG cuts a few corners in its pursuit of pricing, but it’s a great choice for competitive gamers on a budget."
