The Gigabyte MO27Q28G is a 1440p, 280Hz OLED gaming monitor. It's one of Gigabyte's first monitors to use the fourth-gen RGB Tandem OLED panel, which uses a new OLED emitter stack that's designed to deliver brighter highlights and more vivid colors compared to older panels. It competes with other models that use this fourth-gen panel, like the ASUS ROG Strix OLED XG27AQWMG and the LG 27GX700A-B. It has a decent selection of gaming features, like HDMI 2.1 bandwidth, G-SYNC Compatibility, and FreeSync Premium Pro, and it has a small built-in USB hub.
Our Verdict
The Gigabyte MO27Q28G is a fantastic monitor for PC gaming. Motion is incredibly smooth and responsive thanks to its high 280Hz refresh rate and nearly instantaneous response time. It also has low input lag at the max refresh rate, so your actions are perfectly in-sync with the action on the screen. It delivers incredible picture quality thanks to its near-infinite contrast ratio, and blacks are deep and inky with no haloing around bright highlights. There are some downsides, though: distracting VRR flicker when the frame rate is unstable, and a noticeable red tint in certain shades of gray that can't be corrected.
Near-instantaneous response time for sharp motion.
Low input lag, especially at the max refresh rate.
Small specular highlight details stand out well.
280Hz refresh rate and VRR support.
Deep, inky blacks with no haloing.
Distracting VRR flicker.
Very bright scenes in HDR aren't as bright as they should be.
The Gigabyte MO27Q28G is an incredible monitor for console gaming. It supports signals up to 4k @ 120Hz with recent gaming consoles, but it has to downscale 4k signals to 1440p, and it doesn't support Dolby Vision with the Xbox Series S|X. Motion is incredibly sharp, though, thanks to its nearly instantaneous response time, and it has low input lag for a responsive gaming experience. It also delivers fantastic picture quality when gaming, with high peak brightness, vivid colors, and deep, inky blacks, thanks to its near infinite contrast ratio.

The Gigabyte MO27Q28G is good for office use. Its matte anti-reflective coating and high peak brightness make it a suitable choice for a bright office setting, and glare isn't an issue. It also has excellent ergonomics and a wide viewing angle, so you can easily place it in an ideal viewing position. It has just okay text clarity, though, and text isn't as sharp as other monitors with the same pixel density. There's also a small risk of burn-in with constant exposure to the same static elements over time.

The Gigabyte MO27Q28G is an excellent monitor for editing. It has excellent color accuracy when using the 'sRGB'Picture Mode, but midtones and bright highlights are crushed a bit. It delivers incredible picture quality, with deep, inky blacks, and there's no distracting haloing around bright highlights. It displays a wide range of colors, with nearly perfect coverage of the Adobe RGB color space. Unfortunately, text clarity is just okay, as there's some color fringing caused by its subpixel structure. There's also a small risk of burn-in with constant exposure to the same static elements over time.

The Gigabyte MO27Q28G has good peak brightness. It gets bright enough to fight glare in SDR when you're in a well-lit room. HDR content is bright enough to stand out well, but very bright scenes aren't quite as vibrant as they should be.

Differences Between Sizes And Variants
We bought and tested the 27-inch Gigabyte MO27Q28G, which is the only size available. Gigabyte also sells it with a glossy coating, known as the Gigabyte MO27Q28GR. These results are valid for both models except for reflection handling.
| Model | Panel | Max Refresh Rate | Screen Coating |
|---|---|---|---|
| MO27Q28G | 4th Gen WOLED | 280Hz | Matte |
| MO27Q28GR | 4th Gen WOLED | 280Hz | Glossy |
The unit we bought was made in China in September 2025. We tested it with firmware version F06.
Popular Monitor Comparisons
The Gigabyte MO27Q28G is a 27-inch, 1440p OLED gaming monitor with a 280Hz refresh rate. It's one of the first models to hit the market that uses the new fourth-gen RGB Tandem OLED panel, competing with the LG 27GX700A-B and the ASUS ROG Strix OLED XG27AQWMG. This new panel allows the monitor to get significantly brighter than previous-generation OLED panels, especially in very bright scenes in HDR. The new panel structure also helps it deliver slightly better color purity than other WOLEDs, like the LG 27GX790A-B, but colors still aren't as vivid as on a QD-OLED, like the MSI MPG 271QRX QD-OLED. There are a few noticeable issues with it, though, such as crushed midtones in SDR and a red tint in certain shades of gray.

The Gigabyte MO27Q28G and the ASUS ROG Strix OLED XG27AQWMG are both 1440p, 280Hz gaming monitors with a Tandem OLED panel. They perform similarly for the most part, but one difference is their screen coatings. The ASUS has a glossy coating with a clearer image, while the matte coating of the Gigabyte has fewer mirror-like reflections. An advantage of the Gigabyte is that it has a USB-C port to quickly connect a laptop, which the ASUS doesn't have.
The Gigabyte MO27Q28G is slightly better than the ASUS ROG Strix OLED XG27AQDMG. The newer fourth-generation panel on the Gigabyte delivers higher HDR peak brightness, with brighter specular highlight details and more vibrant bright scenes. The Gigabyte also has a slightly faster refresh rate, but it doesn't make a significant difference.
The Gigabyte MO27Q28G and the LG 27GX700A-B perform almost identically, as they share the same panel. There are some minor differences in picture quality due to how each manufacturer has tuned the panel, but they are minor overall. For example, the LG over-brightens some images, whereas the Gigabyte slightly crushes midtones and bright highlights in SDR. The Gigabyte unit we bought shows a noticeable red tint on certain shades of gray, but the LG doesn't. It seems to vary between units, though, so not all Gigabytes will have it.
The Gigabyte MO27Q28G is a slightly better monitor than the ASUS ROG Strix OLED XG27ACDNG. The Gigabyte gets a lot brighter, so it can handle more glare in a bright room, and it delivers a more impactful HDR experience. The ASUS has better color volume, though, as very bright colors are slightly washed out on the Gigabyte. The ASUS also has a higher max refresh rate, which helps improve motion clarity a bit.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
