AOC CQ27G1 Monitor Review Tested using Methodology v1.1 Reviewed Mar 25, 2020 at 07:44 amLatest change: Retest Jul 04, 2022 at 02:50 pm By Alexander Tozzi, Nicholas Di Giovanni, and Olivier Gariepy 7.3 Mixed Usage 7.3 Office 8.1 Gaming 7.0 Multimedia 7.1 Media Creation 5.7 HDR Gaming + Create your own SearchingFinding Store overview test results deals 0 comments Size 27" Pixel Type VA Variable Refresh Rate FreeSync Max Refresh Rate 144 Hz Native Resolution 2560 x 1440

The AOC CQ27G1 is a 27 inch curved screen, 1440p monitor. It's a great choice for gaming thanks to its incredibly low input lag and quick response time, resulting in clear motion, and it supports FreeSync variable refresh rate (VRR) technology to reduce screen tearing in games. With a VA panel, it has a very good contrast ratio, resulting in deep blacks, but that comes at the cost of its viewing angles, which are poor and you'll lose image accuracy when viewed from the side. The lack of HDR support might disappoint some people, but it has impressive out-of-box color accuracy and it displays a very wide range of colors in SDR. Although it doesn't get very bright to combat glare in most rooms, it has decent reflection handling, so it will still perform well in an average-lit room.

Our Verdict

7.3 Mixed Usage

Decent monitor for mixed usage. Gamers will love the incredibly low input lag and great response time, plus it supports FreeSync for a nearly tear-free gaming experience. The 27 inch screen is big enough for productivity, but the viewing angles are poor. It's a decent monitor to watch videos or edit photos with since it displays a wide range of colors and has great out-of-box color accuracy, but it doesn't support HDR content. The contrast ratio is great for dark room viewing and in bright rooms; it doesn't get very bright, but has decent reflection handling.

Pros

• Incredibly low input lag.
• Very good contrast ratio.
• Impressive out-of-box color accuracy.

Cons

• Poor viewing angles.
• Doesn't support HDR.

SearchingFinding Store See our Mixed Usage Recommendations 7.3 Office

The AOC CQ27G1 is okay for office use. The 27 inch, 1440p screen is big enough to open multiple windows at once, but the poor viewing angles means it's not ideal to share your screen with coworkers. However, the gray uniformity is excellent, so solid colors, such as on a web page or a document, look great. It's best suited for moderately-lit rooms since it has decent reflection handling and it doesn't get very bright.

SearchingFinding Store See our Office Recommendations 8.1 Gaming

Great monitor for gaming. The AOC CQ27G1 has an incredibly low input lag, great response time at its max refresh rate, and it supports FreeSync VRR technology to reduce tearing in games. The 1440p screen provides an immersive gaming experience, but unfortunately, the viewing angles are poor, so it's not suggested for co-op gaming. However, it performs well in dark rooms thanks to its very good contrast ratio, displaying deep blacks.

SearchingFinding Store See our Gaming Recommendations 7.0 Multimedia

The AOC CQ27G1 is alright for multimedia use. The 1440p resolution displays fine details and the 27 inch size is big enough for you to sit back and enjoy your favorite videos. Unfortunately, it doesn't support HDR and the viewing angles are poor, so it's not good for watching content with others. However, it displays a very wide range of colors and it has a very good contrast ratio, resulting in deep blacks when viewed in dark rooms.

SearchingFinding Store See our Multimedia Recommendations 7.1 Media Creation

Decent for media creation. There's plenty of screen space on the 27 inch curved monitor, and it has great coverage of the Adobe RGB color space used in photo editing. Sadly, it's not ideal to share your screen with others due to its poor viewing angles. However, it has excellent gray uniformity, so the screen won't darken around the edges.

Differences Between Sizes And Variants

We tested the 27 inch AOC CQ27G1, which is also available in a 32 inch size, the AOC CQ32G1, but we expect the results to be valid for both sizes. There are similar 144Hz models available from AOC, which are listed below.

If someone comes across a different type of panel or if their CQ27G1 doesn't correspond to our review, please let us know and we'll update the review. Note that some tests such as gray uniformity may vary between units.

Update 08/31/2020: We've also tested the AOC CQ27G2, which is very similar to this one, but with a slightly more aggressive curve.

Model	Size	Resolution	Curve	Europe Availability
C24G1	24"	1080p	1500R	Yes
C27G1	27"	1080p	1800R	Yes
CQ27G1	27"	1440p	1800R	No
C32G1	32"	1080p	1800R	Yes
CQ32G1	32"	1440p	1800R	Yes
CU34G2X	34"	3440x1440	1500R	No

Compared To Other Monitors

The AOC CQ27G1 doesn't perform well compared to some of its competitors. Although it performs great as a gaming monitor, it doesn't perform well as a monitor for many other types of use. The Samsung CHG70 and the MSI Optix MAG271CQR are also 27 inch curved screen, 1440p monitors and both are better choices that the AOC.

See our recommendations for the best gaming monitors, the best 1440p monitors, and the best 27 inch monitors.

AOC CQ27G2 SearchingFinding Store

The AOC CQ27G1 and the AOC CQ27G2 are nearly identical, and most of the differences we measured can be attributed to panel variance. The newer CQ27G2 uses a slightly different panel structure and has clearer text than the CQ27G1, and it has a slightly more aggressive curve (1500R vs. 1800R).

Compare Side-by-Side SEE OUR REVIEW AOC CQ32G1 SearchingFinding Store

The AOC CQ27G1 is a bit better overall than its bigger variant, the AOC CQ32G1. The CQ27G1 has a different stand with much better ergonomics and it has a quicker response time. However, the CQ32G1 gets much brighter, it has wider viewing angles, and it handles reflections in really bright rooms a bit better.

Compare Side-by-Side SEE OUR REVIEW LG 27GL850-B/27GL83A-B SearchingFinding Store

For most uses, the LG 27GL850-B/27GL83A-B performs much better than the AOC CG27G1. The LG has an IPS panel that provides wider viewing angles and it can't get a lot brighter, making it more suitable for bright environments. Also, the LG supports HDR and has a much faster response time, at both maximum refresh rate and at 60Hz. On the other hand, the AOC has a VA panel that has significantly better dark room performance and it has an impressive out-of-the-box color accuracy.

Compare Side-by-Side SEE OUR REVIEW Samsung CHG70 SearchingFinding Store

The Samsung CHG70 is better than the AOC CQ27G1. The Samsung supports HDR, can get much brighter, has much better gradient handling, and the response time is quicker. The Dell is also compatible with NVIDIA graphics cards despite having native FreeSync support, while the AOC isn't. On the other hand, the AOC has a bit better contrast ratio and the out-of-box colors are more accurate.

Compare Side-by-Side SEE OUR REVIEW MSI Optix MAG271CQR SearchingFinding Store

The MSI Optix MAG271CQR is a slightly better monitor than the AOC CQ27G1. Both are 144Hz, 1440p monitors, but the MSI has a much better response time for gaming, it can get brighter, does a better job at handling reflections, and it has better viewing angles. Meanwhile, the AOC has much better black uniformity, better ergonomics, and much more accurate out-of-box colors. The MSI is better suited for bright rooms, while the AOC performs better in the dark.

Compare Side-by-Side SEE OUR REVIEW Dell S2719DGF SearchingFinding Store

The AOC CQ27G1 is a slightly better monitor than the Dell S2719DGF. The AOC uses a VA panel, so it has a much better contrast ratio and black uniformity, and the colors are more accurate. Meanwhile, the Dell uses a TN panel, so it has a much quicker response time at its max refresh rate of 155Hz and at 60Hz. Both monitors have native FreeSync support, but the Dell is also compatible with some NVIDIA graphics cards.

Compare Side-by-Side SEE OUR REVIEW ViewSonic VX2758-2KP-MHD SearchingFinding Store

The ViewSonic VX2758-2KP-MHD is a bit better monitor than the AOC CQ27G1, but their differences mainly come down to different panels. The ViewSonic has an IPS panel, so the viewing angles are better. It can also get brighter, the response time is quicker, and it covers more of the sRGB color space used in most content. The AOC has a VA panel, so it's better suited for dark rooms thanks to its great contrast ratio, and its colors are more accurate out of the box.

The AOC CQ27G1 has a gamer-friendly look with a black finish and some red on the front, back, and the stand. It also has thin bezels on three of the sides.

— Design Stand Width 17.0" (43.3 cm) Depth 9.7" (24.7 cm)

The stand is wide and there's space to put stuff in front of it. It supports the monitor well.

— 6.9 Design Ergonomics Height Adjustment 5.4" (13.8 cm) Switch Portrait/Landscape No Swivel Range -30° to 30° Tilt Range -20° to 5°

Okay ergonomics. The AOC CQ27G1 has a wide swivel range but limited tilt range, and as is the case with most curved monitors, you can't switch it into portrait mode.

— Design Back Wall Mount VESA 100x100

The back of the AOC CQ27G1 has a gamer-friendly design on it. It can be VESA mounted and there's a quick-release on it. There's cable management through the stand.

— Design Borders Borders 0.3" (0.7 cm)

The borders are thin, perfect for a multi-monitor setup.

— Design Thickness Thickness (with stand) 5.6" (14.2 cm) Thickness (without stand) 3.1" (7.9 cm)

Since the AOC CQ27G1 has a curved screen, it's thicker than most flat monitors. However, it's much thinner than the Samsung CHG70.

— 7.5 Design Build Quality

The AOC CQ27G1 has a good build quality. It's entirely built out of plastic, which feels solid. There's not a lot of flex to it except near the inputs, and the bezels don't bend either. However, there's a bit of a gap between the bottom bezel and the back, but overall, it's well-built. The MSI Optix MPG27CQ has a similar design and has a better build quality.

— Picture Quality 8.0 Picture Quality Contrast Native Contrast 3,263 : 1 Contrast With Local Dimming N/A

As is the case with most VA panel monitors, the AOC CQ27G1 has a very good contrast ratio. Blacks appear as they should when viewed in the dark.

Impressive out-of-box color accuracy. Most colors appear accurate, although the color temperature is colder than the 6500K target, so some colors will have a blue tint to them. Overall, the gamma curve follows the target well, but dark scenes will be darker than they should, and bright scenes will be brighter.
