The Gigabyte G27QC is a great budget gaming monitor. It shares many similarities with its bigger sibling, the Gigabyte G32QC, as it also features a VA panel with a 1440p resolution and a 165Hz refresh rate. It handles reflections well and gets bright enough to provide good visibility in well-lit environments. It also performs well in dark rooms thanks to its high contrast ratio. It has a fast response time to deliver clear motion in fast-moving scenes, and variable refresh rate support to reduce screen tearing. Sadly, it has narrow viewing angles and poor ergonomics, which isn't ideal if you want to share work, content, or play co-op games. Also, it doesn't get very bright in HDR, so HDR content doesn't look much different than in SDR.

Our Verdict

7.5 Mixed Usage

The Gigabyte G27QC is a good monitor for most uses. It delivers great gaming performance with its low input lag, fast response time, and 165Hz refresh rate. Its large screen and high resolution are also well-suited for productivity; however, it has narrow viewing angles and poor ergonomics, making it difficult to place it at your optimal viewing position or for sharing work. Unfortunately, even though it supports HDR, it can't get bright enough to deliver a satisfying HDR experience.

Pros
  • Great contrast ratio.
  • Great resolution and size.
  • Good reflection handling.
Cons
  • Sub-par viewing angles.
  • Poor ergonomics.
7.3 Office

The Gigabyte G27QC is decent for office use. It has a high resolution to render text clearly, and its 27 inch screen provides plenty of space for multitasking. However, its poor ergonomics and narrow viewing angles make it harder to share work or content. On the upside, it has good reflection handling, and the backlight is flicker-free.

Pros
  • Great resolution and size.
  • Good reflection handling.
  • Excellent gray uniformity.
Cons
  • Sub-par viewing angles.
  • Poor ergonomics.
  • Bad black uniformity.
8.0 Gaming

The Gigabyte G27QC is great for gaming. It has low input lag, quick response time, and a 165Hz refresh rate to provide a smooth and responsive gaming experience. It supports FreeSync to reduce screen tearing and is also G-SYNC compatible. Unfortunately, it isn't ideal for co-op gaming due to its narrow viewing angles and poor ergonomics. Its high contrast ratio makes it a good choice for dark rooms; however, backlight bleed can be an issue.

Pros
  • High refresh rate.
  • Fast response time.
  • Great resolution and size.
  • Good reflection handling.
Cons
  • Poor ergonomics.
  • Bad black uniformity.
7.5 Multimedia

The Gigabyte G27QC is good for media consumption. It has a large high-resolution screen that delivers good picture quality. It handles reflections well in bright rooms, and its high contrast ratio is great for dark room viewing. Sadly, its narrow viewing angles and poor ergonomics make it less ideal for sharing content.

Pros
  • Great contrast ratio.
  • Great resolution and size.
  • Good reflection handling.
  • Excellent gray uniformity.
Cons
  • Sub-par viewing angles.
  • Poor ergonomics.
  • Bad black uniformity.
7.5 Media Creation

The Gigabyte G27QC is good for content creation. Its large screen allows you to work with multiple windows opened side-by-side, and its 1440p resolution lets you see all the fine details in your work. It has an excellent SDR color gamut and good color accuracy out-of-the-box. Sharing work or content is a bit more challenging due to its poor ergonomics and narrow viewing angles.

Pros
  • Great contrast ratio.
  • Great resolution and size.
  • Good reflection handling.
  • Excellent gray uniformity.
Cons
  • Sub-par viewing angles.
  • Poor ergonomics.
  • Bad black uniformity.
6.9 HDR Gaming

The Gigabyte G27QC is okay for gaming in HDR. It delivers a smooth gaming experience with its high refresh rate and quick response time, and it supports variable refresh rate to help reduce screen tearing. Unfortunately, it doesn't get bright enough in HDR to make highlights pop, and our unit has a significant amount of backlight bleed, which can be distracting.

Pros
  • Great contrast ratio.
  • High refresh rate.
  • Fast response time.
  • Great resolution and size.
Cons
  • Poor ergonomics.
  • Doesn't get bright enough for HDR.
  • Bad black uniformity.

The Gigabyte G27QC has a simple design and looks exactly like its bigger brother, the Gigabyte G32QC. The screen is curved, which helps a bit with visibility on the sides, especially when sitting up close. It has thin borders on three sides and a thicker bottom bezel. The V-shaped stand provides sturdy support but takes a fair amount of desk space.

Build Quality

The Gigabyte G27QC's build quality is good. Like the Gigabyte G32QC, it has a full plastic construction that feels sturdy overall, except for the lower portion of the back where it flexes a lot. The plastic covering the tilt hinge feels cheap but doesn't seem to affect the hinge itself. The tilt and height adjustments feel good, and the stand supports the monitor well.

Good SDR peak brightness. The monitor likely processes our test pattern differently, as it's much brighter in regular content than the peak brightness measured using our test pattern. The brightness is remarkably consistent across different content and should be enough to overcome glare in bright lighting conditions.

We measured the SDR peak brightness after calibration, using the 'Custom 1' Picture Mode, with Brightness set to max.

The Gigabyte G27QC has mediocre HDR peak brightness. Even though it gets brighter in regular content, it isn't any brighter than in SDR and isn't bright enough to bring out highlights in HDR content.

We measured the HDR peak after calibration, using the 'Custom' Picture Mode, with Brightness set to max.

Before calibration, the Gigabyte G27QC has good color accuracy. Most colors are only slightly inaccurate, and the same goes for white balance. The color temperature is warmer than our 6500K target, resulting in a slight reddish tint. Gamma doesn't follow the sRGB curve all that well, as dark scenes are too dark and bright scenes are too bright. Unlike the Gigabyte G32QC, the sRGB Picture Mode is the most accurate preset and the one that we used for testing.

After calibration, the color accuracy is exceptional. White balance and gamma are nearly perfect. The remaining color inaccuracies shouldn't be noticeable to the naked eye, except for blue, which is typical for LCDs. The color temperature is much closer to our target, but slightly on the cooler side.

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 Gigabyte G27QC has a decent HDR color gamut. It has good coverage of the DCI P3 color space commonly-used in HDR content, but its coverage of the wider Rec.2020 is only mediocre.

Note that the DCI P3 coverage is lower than the advertised 92%. This is normal and is due to the way we measure DCI P3. We measure DCI P3 by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors to the DCI P3 primaries. This results in a lower, but arguably more accurate measurement.

The Gigabyte G27QC has great response time when playing at its maximum refresh rate. The recommended overdrive setting is 'Speed'. It provides the best performance but introduces some motion artifacts, as there's a bit of overshoot in bright scenes, and dark scene transitions are slow. The 'Picture Quality' and 'Balance' options cause significantly more motion smearing.

The response time at 60Hz is great. It's slower than at its maximum refresh rate, and as a result, there's slightly more motion blur in fast-moving scenes. The best overdrive setting is different than when running at maximum refresh rate. At 60Hz, we recommend using the 'Balance' setting. This means that you may have to change the setting when you play a game that runs closer to 60fps. The 'Picture Quality' and 'Speed' options have slower response times, and there's a lot of overshoot when using 'Speed'.
