VA

The MSI Optix G27C is an average VA-type gaming monitor with a fast 144 Hz refresh rate and support for variable refresh rates. It features a simplistic stand with limited mobility, and a curved design uncommon in monitors of this aspect ratio. While it has a better contrast ratio than average, its very poor black uniformity causes its picture quality in a dark room to be mediocre. Its very narrow viewing angle also means that a slight change in perspective can easily cause the screen to appear less uniform.

The design of the G27C is basic but still looks stylish. The stand looks good and supports the monitor well, but adjustment options are very limited as the monitor can tilt and nothing else. The rear also looks good with some red flair, and the borders have an average thickness. The build quality is fine, but the whole monitor is plastic.

MSI Optix G27C Build Quality picture

The build quality of the Optic G27C is fine. All of the parts are made of plastic and the monitor doesn't have a premium feel but it shouldn't present a problem for normal usage.

The picture quality of the MSI Optix is sub-standard. Its VA panel has a bad viewing angle, which means the edges of the screen look worse than the center, and the whole screen will look a bit different depending on how you sit. The VA panel's saving grace is its great contrast ratio, which is triple that of most other monitors. This is great in a dark room but is less noticeable in a bright room. The monitor's brightness is decent, but it may appear a bit dim in a very bright room. Fortunately, the screen is very good at fighting reflections, so brightness is less of an issue. The monitor lacks more advanced features like HDR and local dimming that further improve picture quality.

Great contrast ratio for the MSI OPTIX G27C PC monitor. With this high contrast ratio, blacks look deep, especially when viewed in a dark room. This makes a perfect option for people that use there monitor in a dark environment compare to other IPS monitor since IPS can't reproduce deep black like this VA panel monitor.

Bad horizontal viewing angle, but fairly typical for a VA panel. Brightness decreases and blacks turn gray rapidly when the screen is viewed at an angle, while colors degrade less at an angle. The curve of this monitor does help to relieve this viewing angle because the angle of the screen relative to the user is decreased near the screen edges.

After calibration, the monitor accuracy is excellent. The white balance dE and color dE are now under 1, which is great even for professionals. The gamma now tracks our 2.4 target perfectly and the curve is almost perfect too. Looking more closely at the color accuracy, pretty much all color are tracking their target very closely, except the 100% blue primary, but this is not really too problematic.

The Optix has a high 144 Hz native refresh rate, which is great for gaming. It also has FreeSync so it can adjust the screen's refresh rate to match the frame rate of a compatible graphics card, which allows playing graphically-intensive games with significant framerate drops without tearing or stuttering. Unfortunately, the FreeSync range doesn't go below 90 Hz like most FreeSync monitors, so stuttering or tearing may occur when a game's framerate drops below 90 Hz.

Excellent low input lag, mostly due to the fast scan time of 144Hz. The 60 Hz input lag is higher as expected but is still fairly low. The FreeSync input lag is actually lower than the input lag at native refresh rate, which is great.

Ordinary monitor for a mixed usage. While it isn't a completely terrible display, the G27C's overall performance is below average. Thanks to its 144 Hz refresh rate and low input lag, it does provide a decent gaming experience, but its mediocre picture quality and the very narrow viewing angle can often cause issues.
Subpar monitor for use in an office. The MSI Optix G27C's stand provides very little adjustment for comfort, and the lack of a VESA mount makes it difficult to solve. Combined with its very narrow viewing angle and average brightness, it makes for a monitor that is both difficult to use in a team environment and less than seamless for a single user.
Decent monitor for playing video games. The 144 Hz refresh rate and Freesync support enable a smooth and responsive experience, and the very low input lag helps make games feel connected. Unfortunately, the monitor's subpar picture quality and low pixel density negatively impact immersion enough to be a detriment.
Below average monitor for multimedia use. While the MSI G27C can cover the s.RGB color volume better than average thanks to its good contrast ratio, its blotchy blacks are significant enough to be damaging to the picture quality. It also lacks any HDR capabilities, which stops it from seeing any picture quality enhancement from wider gamut content.
The MSI Optix G27C is a monitor for media creation. While it does cover the s.RGB and Adobe RGB color volumes better than average, its very narrow viewing angle causes the screen to be inaccurate in most viewing positions, and its basic 8 bits of color depth is limiting for more professionally-oriented users.

I just picked up this monitor, upgrading from a 60hz IPS unit. On FPS games I am seeing slight motion blur/ghosting that I have never had on the older monitor. The motion is very smooth the ghosting trail doesn't seem normal. Is there anyway to fix this?

Hi and thanks for contacting us. The Optix G27C does have a slight motion blur, as you can see on our test picture below and it is normal for this monitor. One thing that you could try is to raise the brightness and/or raise the gamma since the 0-20% transition is very long. Increasing the brightness and/or the gamma will raise the black (the screen will be brighter) and might help with the long 0-20% transition.

If this monitor has 178 degree viewing angle, why would people say it has a very narrow viewing angle. That would have to mean the specs are wrong or the reviewers are wrong. I want to hold off buying this monitor until I solve that issue.
Unfortunately, manufacturers specifications of aspects like viewing angle tend to be based on ambiguous and unrepresentative standards of measurements. When looking across a wide range of monitors, their stated viewing angle tends to be within a range of 170 to 180 degrees, yet in reality, just about no monitor is usable when viewed from that angle. Our test is based on the established thresholds for just noticeable difference, and the angle for each section of the test is the point at which the monitor's picture shows a major deviation from the source. You can learn more about our viewing angle test in our TV section here (the methodology is the same, but our monitor test applies it vertically as well).

My g27c2 monitor I just received has the EXACT same backlight bleed. Even to the point of the top left and the bottom right being the heaviest. Do you think this could be fixed by removing some of the pressure caused by the bezel. It seems the screen is pinched.
If you can still return the monitor it's safer to do that, taking the monitor apart may void your warranty. If you have no other choice, it's possible you could reduce the backlight bleed by relieving some of the pressure on the diffuser, but it's risky because you'd have to take apart the whole monitor. It's probably not the plastic bezel that's causing the pressure, it's likely the metal frame of the panel itself, which might not be adjustable without breaking it.

Does the FPS mode on the MSI Optix G27C decrease input lag at all?
Just tested, no change with or without. Those modes (FPS, RTS, Movie, Eye Saver) are picture modes that just change image settings (and disable Brightness and Contrast adjustment).
