The MSI Optix G27C4 is an entry-level display announced in late 2019. It has a curved display panel and an outstanding 165Hz refresh rate, making it one of the best computer monitors for casual gaming. Still, one of the features that it shares with some of the top gaming monitors is a low input lag of 4.3ms. It also features dual HDMI 2.0 ports and has a high contrast ratio of 3390:1. This high ratio makes it a lot better for dark room viewing than the MSI Oculux NXG253R, which has a ratio of 955:1 and makes black colors appear grey. With a peak brightness level of 335 nits, the G27C4 gets bright enough for content to stay visible in a well-lit room, and since it has a wide color gamut (98.4% coverage of the sRGB color scale), it is also able to deliver rich and saturated colors.

While product testers hailed the G27C4 for its impressive 165Hz refresh rate and high contrast, they felt that its lack of HDR content was a disadvantage that might make buyers turn to the LG 27GP950-B. They also complained that adjustments were hard to make and that its viewing angles were narrow.

Consensus
our Verdict
The MSI Optix G27C4 has received praise from critics for its 165Hz refresh rate, which stemmed from the tear-free gaming experience they enjoyed during their tests. Reviewers from Tom’s Hardware were also pretty happy with its 3390:1 contrast ratio, as this proved to be high enough to keep blacks punchy when they tested it in a dimly lit setting. They also liked it for office use since it had great reflection handling and a 1080p screen resolution that allowed for decent text clarity. Experts from Tech Radar were also pleased with its curvature, as they confirmed that this curved design allowed for more immersive gameplay, even though its 27-inch screen does not offer as much screen real estate as the 38-inch LG 38GN950-B. The display also has Variable Refresh Rate support for both FreeSync and G-Sync technologies, and MSI Anti-Flicker Technology to prevent eye strain over extended use.
ReasonS to Buy
