The CoolerMaster GP27U, being a premium choice with MiniLED technology, offers superior image clarity, color accuracy, and better performance for HDR gaming and media consumption, ideal for those who are keen on high-end graphics and photo editing. However, if your primary focus is on mid-range gaming and general productivity without the need for advanced color work, the more affordable LG 27GP83B would be sufficient and also supports a slightly higher refresh rate for competitive gaming. Keep in mind, the LG falls short in HDR quality and color fidelity compared to the CoolerMaster. Give Feedback

"The LG 27GP83B-B offers today’s sweet spot in gaming specs and capabilities in a well-designed premium package. It’s the first 1440p upgrade over the previous releases such as the LG 27GL83A-B with improvements in image quality thanks to its Nano IPS panel."
