If you're on a tighter budget and looking for general productivity with excellent image clarity and color accuracy for print photo editing, the CoolerMaster GP27U is a solid choice, though it's not the best for fast-paced competitive games due to its refresh rate. In contrast, the LG 27EQ850 excels in competitive gaming with its superior refresh rate and is also suitable for digital photo and video editing, but it comes at a higher price and its brightness is lower, which might not be ideal for well-lit rooms or HDR content. Consider how much you're willing to invest and which use case—professional media work or gaming—matters more to you. Give Feedback
