Gigabyte Aorus FI32U Review: 4K 144Hz 1ms FreeSync IPS Gaming Monitor

The Gigabyte Aorus FI32U is a 32" 4K 144Hz 1ms IPS gaming monitor with HDMI 2.1, FreeSync Premium Pro and DisplayHDR 400.

Bottom Line

If you have a powerful enough PC to run games at 4K UHD with high frame rates and picture settings – and you’ve been looking for a 32″ monitor, the Gigabyte Aorus FI32U might be for you!

It delivers crisp image quality with vibrant colors, quick response time, and smooth VRR performance. Moreover, it has plenty of useful features, an ergonomic stand, and rich connectivity options.


The Gigabyte Aorus FI32U was the first 32″ 4K 144Hz gaming monitor available for under $1,000 – the combination of specifications many have been eagerly waiting for!

Image Quality

The Aorus FI32U was also the first monitor based on a 31.5″ IPS panel with the Eyesafe certification that ensures reduced emission of harmful low-blue lights even when a dedicated low-blue filter mode is not activated and without a negative impact on color accuracy.

The 4K UHD resolution looks incredible on the 31.5″ sized screen of the monitor thanks to the high pixel density of 140 PPI (pixels per inch). You get sharp details and text as well as plenty of screen space. Some users don’t use any scaling here, but others might prefer ~125% scaling to make small text easier to read.

Keep in mind that you’ll need a high-end PC system in order to maintain decent frame rates and picture settings at 4K UHD in the latest games.

Moving on, the IPS panel of the Gigabyte Aorus FI32U monitor ensures 178° wide viewing angles for flawless image quality regardless of the angle you’re looking at the screen.

It covers 90% of the DCI-P3 color space (~123% sRGB), which results in rich and vivid colors. You can also use the provided sRGB emulation mode to restrict the gamut to ~100% sRGB for more accurate output when viewing SDR content. In this mode, you can adjust the brightness, but not other settings.

The peak brightness amounts to 350-nits, so the screen can get more than bright enough under normal lighting conditions, while the contrast ratio is 1,000:1 – as expected from an IPS panel display.

Blacks won’t be quite as deep as that of VA panels with a ~3,000:1 contrast ratio, but they’re decent nonetheless. Some IPS glow is present as well, but its intensity varies across different units of the monitor; in most cases, it’s completely manageable.

Now, the low contrast ratio and IPS glow can take away from the overall viewing experience in dark rooms, but that’s the expected drawback of IPS technology. VA panels have their own flaws, such as narrower viewing angles and gamma/contrast shifts.

The Gigabyte Aorus FI32U also supports HDR (High Dynamic Range) and has VESA’s DisplayHDR 400 certification. Even though the entry-level HDR400 certification doesn’t require local dimming, the monitor does have a 16-zone local dimming solution.

Further, HDR content gets a boost in brightness up to 400-nits – which in addition to the 16-zone local dimming, wide color gamut and high screen resolution can make some HDR scenes look noticeably better than SDR.

Still, you’re not getting the ‘true’ HDR viewing experience, which would require a much more expensive full-array local dimming solution, but at least there’s some improvement in HDR content.

In other words, you shouldn’t buy this monitor for its HDR support. Some HDR content won’t look any better, but some scenes, especially those with bright and dark objects far apart, will look great!


The Gigabyte Aorus FI32U 4K 144Hz gaming monitor boasts a rapid 1ms GtG pixel response time speed for no noticeable trailing behind fast-moving objects and a smooth fast-paced gaming experience.

There are five response time overdrive modes: Off, Picture Quality, Balance, Speed, and Smart OD.

The default Off setting offers the best gaming experience with no particularly noticeable ghosting or overshoot across the entire refresh rate range.

Between 120Hz and 144Hz, the Picture Quality mode is better as it has less ghosting at a cost of minor overshoot, whereas between 60Hz and 100Hz (or if you’re using VRR), Picture Quality will have too much overshoot.

Smart OD is supposed to automatically select the best overdrive setting according to frame rate, but it’s not well-optimized and should be avoided.

The Aorus FI32U has AMD’s FreeSync Premium Pro certification, ensuring flawless VRR performance and optimal HDR tone/gamut mapping in compatible games. The supported VRR range is 48-144Hz over both HDMI and DisplayPort.

While the monitor is not officially certified as ‘G-SYNC Compatible’ by NVIDIA, VRR works without issues with GeForce cards as well.

Gigabyte’s Aim Stabilizer Sync is also available, which allows you to use the Aim Stabilizer backlight strobing technology at the same time as VRR. This reduces perceived motion blur and prevents screen tearing, but picture brightness is reduced.

It also introduces screen flickering that’s invisible to the human eye, but those sensitive to flicker may experience headaches after prolonged use. When Aim Stabilizer/Sync is disabled, the backlight is completely flicker-free.

Input lag is low, so there’s no perceptible delay between your actions and the result on the screen. To ensure the lowest latency, make sure you have at least the F06 firmware version installed.


Gigabyte M28U OSD Menu Layout

The Gigabyte Aorus FI32U offers plenty of features and adjustments, all of which are neatly organized in the OSD (On-Screen Display) menu or the OSD Sidekick desktop application.

Beneath the monitor’s bottom bezel is a directional joystick for quick and easy navigation through the menu.

Useful gaming features include Black Equalizer (improves visibility in darker scenes), crosshair overlays and various picture presets (FPS, RTS/MOBA, three customizable modes, etc.).

You’ll also find PiP/PbP, 6-axis hue/saturation, sharpness and gamma settings.

The Dashboard feature allows you to track PC system performance, such as CPU/GPU temperature, utilization, etc. on the screen.

At the rear of the monitor, there’s customizable RGB Fusion 2.0 lighting (color cycle, static, flash and pulse).

Lastly, the monitor has an integrated KVM switch, allowing you to effortlessly swap your keyboard/mouse control between multiple devices connected to the screen.

Design & Connectivity

Gigabyte Aorus FI32U Monitor Design

The stand of the monitor is robust and versatile with up to 130mm height adjustment, 90° pivot, +/- 20° swivel, -5°/20° tilt and 100x100mm VESA mount compatibility.

The bezels are ultra-thin at the top and at the sides, while the screen has a light matte anti-glare coating that eliminates reflections.

Connectivity options include DisplayPort 1.4 with DSC, two HDMI 2.1 ports, USB-C (DP 1.4 Alt Mode), a headphone jack, a microphone jack with ANC (active noise canceling), an audio line-out port and a dual-USB 3.0 hub.

The FI32U also supports the 4K 120Hz mode for the XSX and PS5, as well as 1080p 120Hz (Xbox and PS5) and 1440p 120Hz (Xbox).

Note that the HDMI 2.1 ports of the monitor are limited to 24 Gbps and use DSC (Display Stream Compression) for 4K 144Hz 10-bit color 4:4:4.

This is not an issue for Xbox consoles or modern graphics cards, however, the PS5 is limited to 4K 120Hz 10-bit color with 4:2:0 instead of 4:2:2 as it lacks DSC; you most likely won’t notice it in games though.

Price & Similar Monitors

The Gigabyte Aorus FI32U price ranges from ~$700 to $1,000. We recommend going with the M32U model instead – it’s the same monitor with a different design and without the RGB lighting and ANC that’s usually $100 – $200 cheaper than the FI32U.

However, sometimes both the M32U and FI32U can be found on sale for ~$670, which makes the FI32U a lot better buy.

If you want a 32″ 4K 144Hz IPS monitor, we recommend the Innocn 32M2V for the KTC M32P10 for ~$1,000 since it has proper HDR support with an 1152-zone mini LED FALD backlight.

Alternatively, consider investing $100 – $300 more for the Samsung Odyssey Neo G7 with an 1196-zone mini LED FALD backlight and a curved VA panel.

All in all, the Gigabyte Aorus FI32U delivers excellent SDR image quality thanks to its high pixel density and vibrant colors, while its quick response time and VRR support ensure smooth performance.

It’s expensive, but it’s a premium product aimed at those who can afford to run games at 4K UHD resolution with high frame rates and high picture settings – in which case, it’s worth the money if you want to put your PC to good use.
