The LG 27GP83B would be a solid choice for casual gaming and digital photo editing without spending as much. Its smaller size and higher refresh rate make it suitable for competitive gaming, despite some limitations in contrast and brightness. On the other hand, the MSI MPG 491CQP's larger screen and superior contrast would greatly enhance HDR gaming and media consumption, making it an excellent option for high-end productivity and professional photo and video editing. However, you would be investing substantially more, and it might not be as optimal for fast-paced competitive gaming due to its slightly lower refresh rate and response time. The choice depends on whether you prioritize a high-end visual experience and have a larger budget or you prefer to save money while still having a good gaming and editing experience. Give Feedback
