The Gigabyte G27Q is a great budget gaming monitor. It's similar to the Gigabyte G27QC, except it has an IPS panel. This means it has wide viewing angles, but it comes at the cost of its low contrast ratio that makes blacks appear gray when viewed in the dark. It has features most gamers would want in a 144Hz, 1440p monitor, like variable refresh rate support in the form of native FreeSync support and G-SYNC compatibility. It has a very good response time at its max refresh rate, which results in minimal motion blur, and its input lag is exceptionally low. Unfortunately, it has poor ergonomics, so placing in an ideal viewing position may be difficult. If you want to use it in a well-lit room, it gets bright enough to combat glare and has good reflection handling.

Our Verdict

7.7 Mixed Usage

The Gigabyte G27Q is very good overall. It's great for gaming because it has VRR support, a fast response time, and exceptionally low input lag. It's good for office use and content creators thanks to its wide viewing angles, high peak brightness, and good reflection handling. However, it has poor ergonomics, making placing the screen in an ideal position difficult. While it displays a wide range of colors in HDR, it has a low contrast ratio and doesn't get bright enough to make highlights pop.

Pros
  • Wide viewing angles.
  • Native FreeSync support and G-SYNC compatibility.
  • Exceptionally low input lag.
Cons
  • Poor ergonomics.
  • Low contrast ratio.
7.8 Office

The Gigabyte G27Q is good for office use. It has an IPS panel with wide viewing angles, which is great if you need to share your screen with others. The 1440p resolution delivers clear text, and the 27 inch screen offers enough space to multitask. It gets bright enough to combat glare in well-lit rooms and has good reflection handling. Sadly, it has poor ergonomics as you can't swivel it.

Pros
  • Wide viewing angles.
  • Great 1440p resolution and 27 inch size.
  • Gets bright enough to combat glare.
Cons
  • Poor ergonomics.
8.0 Gaming

The Gigabyte G27Q is great for gaming. It has a high 144Hz refresh rate with both FreeSync support and G-SYNC compatibility. The response time at its max refresh rate is very good, and it has an exceptionally low input lag. It has wide viewing angles if you want to use it for co-op gaming. Unfortunately, it's not the best for dark room gaming because it has a low contrast ratio that makes blacks appear gray.

Pros
  • Great 1440p resolution and 27 inch size.
  • Native FreeSync support and G-SYNC compatibility.
  • Excellent response time at max refresh rate of 144Hz.
  • Exceptionally low input lag.
Cons
  • Poor ergonomics.
  • Low contrast ratio.
  • Lacks a local dimming feature.
7.4 Media Consumption

The Gigabyte G27Q is good for multimedia use. It has a high 1440p resolution that makes images look crisp. It performs well in bright rooms thanks to its high peak brightness and good reflection handling. Sadly, it doesn't perform as well in dark rooms because it has a low contrast ratio, so blacks look gray. Luckily, it has wide viewing angles, which is great if you want to watch content with a friend.

Pros
  • Wide viewing angles.
  • Great 1440p resolution and 27 inch size.
  • Gets bright enough to combat glare.
Cons
  • Poor ergonomics.
  • Low contrast ratio.
7.9 Media Creation

The Gigabyte G27Q is very good for content creators. The large 27 inch screen offers enough room to open multiple windows side-by-side. It has wide viewing angles, so someone viewing from the side still sees an accurate image. However, it has poor ergonomics, and you won't be able to easily place your screen in an ideal viewing position. Lastly, it has an outstanding SDR color gamut with excellent coverage of the Adobe RGB color space.

Pros
  • Wide viewing angles.
  • Great 1440p resolution and 27 inch size.
  • Superb gradient handling.
Cons
  • Poor ergonomics.
  • Low contrast ratio.
6.7 HDR

The Gigabyte G27Q is alright for HDR, but it offers nothing special. While it displays a wide range of colors, it doesn't get bright enough to make those colors look vivid. It also has a low native contrast ratio, and without a local dimming feature, blacks look gray in dark rooms. It doesn't make highlights pop in HDR, so everything looks dull and muted.

Pros
  • Displays wide color gamut for HDR content.
Cons
  • Low contrast ratio.
  • Lacks a local dimming feature.
  • Not bright enough for highlights to really pop.
  • 7.7 Mixed Usage
  • 7.8 Office

The Gigabyte G27Q has decent HDR peak brightness. It's very consistent across different content, meaning small highlights don't stand out against the rest of the image. The EOTF tracks the target fairly well until there's a sharp roll-off at the peak brightness, as it lets highlights get the brightest they can before the source does any tone mapping. We tested HDR peak brightness after calibration in the 'Custom 1' Picture Mode with Brightness at its max.

The accuracy before calibration is good. The dedicated sRGB mode locks colors well to the sRGB color space, and most colors are accurate. However, the white balance is worse, and the color temperature is on the cold side, resulting in a blue tint. On the plus side, gamma follows the sRGB curve well enough. Unfortunately, the sRGB mode locks most picture settings, and if you want to use those settings, you'd have to use another less-accurate mode, as you can see here. If you want better accuracy and an sRGB mode that allows you to customize more picture settings, check out the HP OMEN 27q.

The accuracy after calibration is simply exceptional. Any remaining inaccuracies can't be spotted without the aid of a colorimeter, and the color temperature is extremely close to the 6500K target.

The Gigabyte G27Q's color gamut is outstanding, even better than the Gigabyte G27QC. It has perfect coverage of the commonly used sRGB color space, and photo editors should be happy with the excellent coverage of the Adobe RGB color space.

The Gigabyte G27Q monitor's SDR color volume is fantastic. Thanks to its outstanding color gamut and high peak brightness, it displays colors at a wide range of luminance levels. Unfortunately, it struggles to display deep, saturated colors due to the low contrast ratio.

The HDR color volume is great. It displays some bright colors thanks to the decent HDR peak brightness but can't display darker colors because of the low contrast.

The Gigabyte G27Q has superb gradient handling. There's hardly any banding with shades. Note that even though Gigabyte advertises it as an 8-bit panel, you can achieve a 10-bit signal with a 120Hz refresh rate over DisplayPort or 60Hz over HDMI.

The Gigabyte G27Q has a very good response time at its max refresh rate of 144Hz. Motion looks crisp, and there's minimal blur. The recommended Overdrive setting is 'Speed' because it's the fastest, and there isn't too much overshoot. If the overshoot bothers you, there isn't any in the 'Balance' setting, but it has a slower response time. If you want a monitor with an even faster response time, then consider the Gigabyte M27Q P.

The response time at 60Hz is mediocre. The Overdrive settings are a bit different than at higher refresh rates, as 'Balance' has the fastest response time and less overshoot, but motion still looks blurry. If you want a monitor with a faster response time at 60Hz, check out the ASUS ROG Strix XG27AQ.

The Gigabyte G27Q has a great resolution and size. There's enough space to open multiple windows side-by-side, and the 1440p resolution helps deliver crisp images. This is a better choice for multitasking than 1080p displays, like the MSI Optix G273.

The Gigabyte G27Q works well with the PS5, but without HDMI 2.1 bandwidth, you can't play 4k games up to 120Hz. However, it downscales 4k signals, which results in a sharper image than native 1440p. Although some user reports are saying that firmware F06 makes the monitor incompatible with 1080p and 1440p signals at 120Hz, we didn't experience any issues. For 1080p @ 120Hz, we just had to start a game and return to the menu to see that 1080p @ 120Hz is supported in the Video Output Information page.

macOS Compatibility

There are a few issues using this monitor with macOS, but it works well for the most part. Windows don't always stay in place when resuming from sleep, which can be a bit frustrating. HDR works properly and looks good. The variable refresh rate feature doesn't work properly when on the desktop with a lower framerate, but it works fine in-game.

The Gigabyte G27Q has a few extra features, including built-in speakers. You can see the other features listed below:

  • OSD Sidekick: Allows you to control the on-screen display with your mouse and keyboard.
  • Timer: Puts a timer on the screen.
  • Refresh rate counter: Adds an overlay that displays the current refresh rate.
  • Crosshair: Adds a virtual crosshair for shooter games.
  • Black Equalizer: Adjusts the gamma in dark scenes, so you can see your opponents in the shadows better.
  • Dashboard: Shows diagnostics of the PC. You need to use the USB-B cable for it to work.

There's a Picture-in-Picture option in the OSD Sidekick, but it doesn't work and doesn't show up in the regular on-screen display either.
