The MSI Optix G27CQ4 is a very good budget-friendly gaming monitor with a 27 inch screen and 1440p resolution. It has all the features most gamers are looking for, like FreeSync variable refresh rate (VRR) support and a native 165Hz refresh rate. Its input lag is really low, but even though it has a quick response time, you may notice some motion blur in fast-moving scenes. Its VA panel has a high native contrast ratio, but it lacks a local dimming feature to improve it. The viewing angles are narrow, and the stand doesn't offer many adjustments, so it's hard to place it in an ideal viewing position if you need to share it with someone else. Lastly, it doesn't support HDR, which is somewhat expected for a model in this price range.
Our Verdict

Our unit was manufactured in December 2020 and you can see the label here.
Compared To Other Monitors
The MSI Optix G27CQ4 is a very good budget gaming monitor. It has most features gamers are looking for, like VRR support and a high refresh rate. It also has a great native contrast ratio, but other than that, there's nothing that stands out against its competition. It provides good value for its price, but there are better and cheaper options available, like the Gigabyte G27QC.
Also see our recommendations for the best budget monitors, the best 1440p monitors, and the best gaming monitors.
The MSI Optix G27CQ4 and the Samsung Odyssey G5 C27G55T are both good gaming monitors. They each have a VA panel with a 1440p resolution, and they offer similar features, but the MSI has a 165Hz refresh rate compared to the Samsung's 144Hz. The MSI is also flicker-free at all brightness levels, while the Samsung flickers at lower brightness levels. The Samsung supports HDR, which the MSI doesn't, but it doesn't add much because it can't display a wide color gamut.
The Dell S2722DGM is much better than the MSI Optix G27CQ4. The Dell has better ergonomics, a faster response time, better viewing angles, and better black uniformity. The Dell is also significantly brighter and can better overcome glare. On the other hand, the MSI has better gradient handling and can accept a 10-bit signal.
The MSI Optix G27CQ4 and the MSI Optix G27C4 are both very good gaming monitors. They're built nearly the same, and each has a VA panel with a 165Hz refresh rate. The main difference is that the G27CQ4 has a 1440p resolution, while the G27C4 is limited to 1080p. The G27CQ4 is a better choice for well-lit rooms because it gets much brighter. However, the G27C4 delivers much smoother motion thanks to its quick response time.
The MSI Optix G27CQ4 and the ASUS TUF Gaming VG27WQ1B are both very good gaming monitors, as they each have a VA panel with a 1440p resolution and 165Hz refresh rate. The ASUS supports HDR10, which the MSI doesn't, but it doesn't add much because it doesn't get bright enough to bring out highlights, and it lacks local dimming. In terms of gaming, they each have VRR support and low input lag. The MSI has a quicker response time at its max refresh rate, while the ASUS is quicker at 60Hz, but most people shouldn't notice any difference between the two.
The Gigabyte G27QC is much better overall than the MSI Optix G27CQ4, even though they each have a VA panel, 165Hz refresh rate, and 1440p resolution. The Gigabyte has a quicker response time, resulting in smoother motion, and its BFI feature flickers at a wider range. The Gigabyte also supports HDR10 and has a USB hub, which the MSI doesn't.
The Dell S3222DGM is better than the MSI Optix G27CQ4. The Dell has better ergonomics, making it easier to place in an ideal viewing position. The Dell is also much better for gaming, as it has a much faster response time, especially when gaming at 60Hz.
The BenQ EX2780Q and the MSI Optix G27CQ4 are both very good gaming monitors with different panel types. The BenQ is a 144Hz monitor with an IPS panel with wider viewing angles, and the MSI has a 165Hz refresh rate and a VA panel with higher contrast. The BenQ supports HDR, which the MSI doesn't, and it has quicker response times, so motion looks better.
Test Results
The MSI Optix G27CQ4 looks like the other entry-level MSI monitors that we've tested, like the MSI Optix G27C4. It has an all-plastic construction with a bit of a gamer-friendly tone, but it shouldn't stick out in an office environment.
The tripod stand is wide enough so that you can place stuff in between the legs, like your keyboard and mouse. The feet are metal and support the monitor well.
Sadly, the ergonomics are terrible. You can only tilt it, and even at that, the tilt range is limited.
The back of the MSI Optix G27CQ4 looks exactly like the MSI Optix G27C4. It's all-plastic with a slight gamer-friendly design to it, and there are air vents directly above the hinge for the stand. Sadly, there isn't much for cable management.
The monitor isn't too thick, even with the stand attached, so it shouldn't take up too much space.
The build quality of the MSI Optix G27CQ4 is okay. It's built with generic and cheap-feeling plastic, and the feet are metal. The back panel flexes a bit, and the plastic covering the hinge feels very flimsy. Also, the bottom bezel isn't uniformly attached to the screen and bends a bit.
The contrast of the MSI Optix G27CQ4 is great, which is expected from a VA panel. It displays deep blacks when viewed in the dark, but there's no local dimming feature to improve it. It's higher than the advertised 3000:1 contrast, but this can vary between units.
This monitor doesn't have a local dimming feature. The video above is provided for reference only.
The MSI Optix G27CQ4 has good SDR peak brightness. It's higher than the advertised 250 nits, and it's very consistent across different content. Surprisingly, it gets brighter with real content than with the test slides, so it easily gets bright enough to combat glare. We tested the peak brightness after calibration in the 'User' Picture Mode.
This monitor doesn't support HDR.
The MSI Optix G27CQ4 has a narrow horizontal viewing angle, which is expected for a VA panel. The image looks inaccurate as soon as you move off-center, so it's not suggested for co-op gaming.
Once again, the vertical viewing angle is poor. The image looks inaccurate if you mount the screen above eye level.
The MSI Optix G27CQ4 has excellent gray uniformity. Although the edges are a bit darker than the rest, there's no dirty screen effect in the center, which is great. Uniformity is even better in near-dark scenes, but some backlight bleed is visible along the bottom edge. Keep in mind that uniformity can vary between units.
The black uniformity is bad, but this can vary between units. There's visible backlight bleed along the top and bottom edges, which could be really distracting in dark scenes. However, there's not too much blooming around the center cross.
The out-of-the-box accuracy is impressive. Both colors and white balance are slightly inaccurate, but it shouldn't be noticeable for most people. The color temperature is a bit warmer than the 6500K target, giving the image a slightly reddish tint, but not by much. However, gamma doesn't follow the target all that well as some dark scenes are too dark, and other scenes are over-brightened. Keep in mind that accuracy may vary between units.
After calibration, accuracy is incredible. Any remaining inaccuracies can't be spotted by the human eye, and color temperature is very close to the target. Gamma is also improved, except some really dark and bright scenes are still over-brightened.
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 SDR color gamut is fantastic. It has near-perfect coverage of the sRGB color space used in most content. For photo editors, it has excellent coverage of the Adobe RGB color space.
The MSI Optix G27CQ4 has an outstanding SDR color volume. It displays bright colors and dark colors well.
Even though it's advertised to have 92% coverage of the DCI P3 color space, it doesn't support HDR so we don't test for it.
This monitor doesn't support HDR.
There are no signs of image retention, even after displaying a high-contrast static image. Keep in mind that this can vary between units.
The MSI Optix G27CQ4 has incredible gradient handling. There are no visible signs of banding.
There's no visible sign of color bleed on this monitor.
The MSI Optix G27CQ4 has good reflection handling. It handles a moderate amount of light really well, but struggles if you place the screen opposite a direct source of light, like a window.
The MSI Optix G27CQ4 has good text clarity. Enabling Windows ClearType (top photo) makes diagonal lines more legible, like on the letters R, N, G, and S.

The MSI Optix G27CQ4 has a good response time at its max refresh rate of 165Hz. However, the response times in the darker transitions are slow, and there's too much overshoot in the lighter transitions, so you can still notice motion artifacts in most scenes. The recommended overdrive setting is 'Fastest' because it has a quicker total response time than the other settings.
| Overdrive Setting | Response Time Chart | Response Time Tables | Motion Blur Photo |

The response time at 60Hz is just okay. The recommended overdrive setting is 'Fast' because 'Normal' is too slow, and there's too much overshoot with 'Fastest'. Still, there's way too much overshoot in the lighter transitions, so motion doesn't look all that good. Also, this means that you may have to change the overdrive setting if the frame rate of your game drops.
The MSI Optix G27CQ4 has a flicker-free backlight, which helps reduce eye strain.
The MSI Optix G27CQ4 has a Black Frame Insertion feature to try to improve the appearance of motion. It flickers within a narrow range and can't be used with VRR enabled. Keep in mind that the BFI score is based on the flicker range and not the actual performance.
The MSI Optix G27CQ4 has variable refresh rate support in the form of native FreeSync support. It isn't officially listed as G-SYNC compatible by NVIDIA, but it works. You can achieve its full refresh rate range over a DisplayPort connection. Over HDMI, only FreeSync works, and the max refresh rate is 144Hz.
The MSI Optix G27CQ4 has incredibly low input lag that remains low with VRR enabled. It increases slightly with BFI enabled, but most people shouldn't notice it.
The large 27 inch screen has a high 1440p resolution, which helps delivers crisp images. This is an upgrade over the MSI Optix G27C4, which has a 1080p resolution. There's also a 32 inch version, the G32CQ4, which has the same resolution, resulting in a lower pixel density.
Like some other MSI monitors we've tested, this one doesn't have any USB inputs.
The MSI Optix G27CQ4 is limited on extra features, but it has:
- Crosshair: Adds a virtual crosshair on the screen for FPS games.
- Low Blue Light Mode: Removes blue light to help reduce eye strain.
- Frame Rate Counter: Displays the current frame rate of your game.
