The MSI Optix G27C4 is a decent monitor with impressive gaming performance. With a curved 27 inch screen, its 1080p resolution feels somewhat lacking, but it makes up for it with a high refresh rate, excellent motion handling, and exceptionally low input lag. This monitor is well-suited for dark room gaming thanks to its high contrast ratio, and it can deliver a good picture quality with saturated colors and fluid motion. Sadly, it doesn't support HDR, it has very few extra features, and its mediocre peak brightness can be an issue in very bright rooms.
The MSI Optix G27C4 is a decent monitor for most uses. It can deliver a good picture quality, but its 1080p resolution is a bit low for a 27 inch screen, which is less ideal for multitasking. It's a great gaming monitor, though, as it has a 165Hz refresh rate, excellent response time, and a low input lag to provide a smooth and responsive gaming experience. Additionally, it supports FreeSync variable refresh rate to reduce screen tearing.
The MSI Optix G27C4 is an okay monitor for office use. It has a large 27 inch screen to let you work comfortably, but text may not look as sharp due to its 1080p resolution. Viewing angles are rather poor, and the monitor's bad ergonomics make it hard to adjust to your optimal viewing position. The monitor has good reflection handling, but its low peak brightness may be an issue if you're in a bright room with direct sunlight.
The MSI Optix G27C4 is a great gaming monitor. It has a high refresh rate and a low response time to provide a smooth gaming experience. Input lag is exceptional and there's support for FreeSync variable refresh rate, but unfortunately, its 1080p resolution may be a bit disappointing for fans of RPGs and atmospheric games.
The MSI Optix G27C4 is an okay monitor for media consumption. Its 1080p resolution is a bit low, but its 27 inch screen lets you see comfortably without having to sit up close. Viewing angles may be a problem if you want to share content with others, and even though it has great reflection handling, viewing the screen in a bright room can be difficult due to the monitor's low peak brightness.
The MSI Optix G27C4 is an acceptable monitor for media creation. Its 27 inch screen provides plenty of screen real estate to work comfortably, but the 1080p resolution may be too low for content creators. The monitor has bad ergonomics, making it difficult to adjust to your optimal position, and the VA panel's viewing angles are poor, causing colors to appear washed out when viewed from the side.
The MSI Optix G27C4 is a sub-par monitor for HDR gaming. Although it has a high refresh rate, low response time, and low input lag, this monitor doesn't support any HDR format. In addition, its low peak brightness can't bring out any highlights. Its high contrast ratio is great for dark room gaming, though, as blacks look deep and inky.
The MSI Optix G27C4 has a very simple design. It's mainly made out of matte black plastic. The top and side bezels are thin, but the bottom bezel is much thicker. The stand has a tripod design with a shorter back leg, and the screen is curved.
The stand has a tripod design, though the back leg is much shorter than the front legs. The overall footprint is large, but because the legs are thin, you can still use the space in-between the legs. The stand supports the monitor well and it doesn't wobble at all. If you prefer a similar monitor with a stand that sits flat against the table, then check out the MSI Optix G27C5.
The G27C4 has bad ergonomics. It only allows for tilt adjustments.
The back of the monitor is plastic and has a subtle gamer-oriented design, though it shouldn't look out of place in an office environment. The inputs are easy to access; however, there's no built-in cable management, and the stand doesn't have a quick release feature. There's a joystick at the bottom left corner to navigate the on-screen menu.
The bezels are very thin, which is great for multi-monitor setups.
The build quality of the G27C4 is mediocre. It's mainly made out of plastic and doesn't have a premium feel to it. The stand is also plastic and supports the monitor well.
Like most VA panels, the Optix G27C4 has a great contrast ratio, resulting in deep, inky blacks when viewed in the dark.
This monitor doesn't have a local dimming feature; the video above is provided for reference only.
SDR peak brightness is decent. There's almost no variation in brightness when viewing different content, and it should be bright enough for most well-lit rooms, though it may struggle a bit in direct sunlight. If you're looking for a similar monitor that gets much brighter, check out the Samsung T55.
This monitor doesn't support HDR.
Like most VA panels, horizontal viewing angles on the Optix G27C4 are poor. This is important if you often share content or play co-op games. If you need a monitor with better viewing angles, check out the BenQ EX2780Q.
As with most VA panels, vertical viewing angles are poor. This can affect the top and bottom of the screen if you tend to sit fairly close.
The G27C4 has excellent gray uniformity. It's slightly darker at the top left corner and on the right side of the screen, but it's barely noticeable, and there's almost no sign of dirty screen effect. In dark scenes, it's nearly perfect.
Black uniformity is disappointing. There's some backlight bleed along the top and bottom edges of the screen, as well as some clouding throughout the screen.
Out of the box, the G27C4 has sub-par color accuracy. There are inaccuracies with many colors and with shades of gray. The gamma curve is too low for the most part, resulting in images looking brighter than they should. If you prefer a monitor with great pre-calibration accuracy, check out the ASUS TUF VG27VQ.
After calibration, aside from the color blue, any inaccuracies shouldn't be noticeable without the aid of a colorimeter. The gamma curve follows the target well, so most scenes should appear at the correct brightness.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit even for the same model, due to manufacturing tolerances.
The G27C4 has an excellent SDR color gamut. It covers nearly all of the sRGB color space used in most content, and it has great coverage of the Adobe RGB color space, which is used for professional photo editing.
SDR color volume is outstanding. This monitor can reproduce dark, saturated colors due to its great contrast ratio.
This monitor doesn't support HDR.
This monitor doesn't support HDR.
As with most VA panels, there are no issues with temporary image retention or permanent burn-in.
The G27C4 has impressive gradient performance; however, there's some banding when displaying dark green, dark gray, and blue.
There's no visible sign of color bleed on this monitor.
The Optix G27C4 has good reflection handling. The matte coating diffuses light well and there are no distracting bright spots. It's very similar to the MSI Optix MAG271CQR.
Text clarity is decent, though it can be improved by enabling ClearType (top photo), as it significantly improves the appearance of diagonal lines, as seen in the letters R and N.

The Optix G27C4 has a great response time when playing at maximum refresh rate. As with most monitors, the overdrive level can be adjusted. We recommend the 'Fastest' setting, as it provides the best performance. However, there's a little bit of overshoot, which can cause the appearance of some artifacts.
The G27C4 has a flicker-free backlight to help reduce eye strain.
The Optix G27C4 has a black frame insertion feature to help reduce motion blur, but it can't be used when FreeSync is enabled.
Refresh rate on the Optix G27C4 is excellent. It has a wide VRR range; however, it maxes out at 144Hz when using an HDMI connection. If you want a monitor with a higher refresh rate, the Acer XV273X has a 240Hz panel.
Input lag is exceptionally low. It's slightly higher when playing at 60Hz or when variable refresh rate is enabled, though it shouldn't be noticeable for most people.
The size and resolution of the G27C4 are decent. The 27 inch screen is great for gaming and productivity, but the 1080p resolution is a bit low for this size, which impacts text clarity. However, the lower resolution helps to achieve higher frame rates when gaming. If you prefer a monitor with 1440p, check out the Nixeus EDG 34.
