Gigabyte G34WQC Monitor Review

The Gigabyte G34WQC has a simple design that looks almost identical to the Gigabyte G32QC but in an ultrawide format. It has the same V-shaped stand and thin borders.

The Gigabyte G34WQC has a good build quality, similar to the Gigabyte G32QC. It's mostly plastic, and although there's a bit of flex on the back panel, it feels sturdy overall. The stand supports the monitor well and doesn't wobble much. The height and tilt adjustments feel stable and solid, but the plastic covering the hinges feel cheap, and the same goes for the plastic covering the stand's base. There aren't any brackets holding the monitor to the stand, so they're attached with screws only. This means that if you need to remove the stand to VESA-mount it, you have to be careful not to let the monitor fall after unscrewing it from the stand.

The Gigabyte G34WQC has poor ergonomics. Due to its ultrawide format, it's somewhat expected that it can't rotate to portrait mode. Unfortunately, it also lacks swivel adjustment. The back of the monitor is plain except for the branding and the glossy top portion. There's a small cutout at the bottom of the stand for cable management. There's no quick-release feature to remove the stand for VESA-mounting.

The stand takes up a fair amount of desk space, but it supports the monitor well and doesn't wobble much.

There's a joystick on the right backside of the monitor that allows you to power it On/Off and navigate the on-screen menu.

The Gigabyte G34WQC has a great contrast ratio that allows it to produce deep blacks, making it a good option for dark rooms.

The Gigabyte G34WQC doesn't have a local dimming feature. The video above is provided for reference only.

The Gigabyte G34WQC has great SDR peak brightness, a little above the advertised 350 cd/m². It's remarkably consistent when displaying different scenes, and it's bright enough to overcome glare in nearly any lighting conditions.

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

The Gigabyte G34WQC has decent HDR peak brightness and meets the required 400 cd/m² for its DisplayHDR 400 certification. Like in SDR, the brightness is very consistent across different content. It's bright enough to deliver an okay HDR experience in video games, especially if you game in a dark room, but it isn't enough for HDR movies.

We measured the HDR peak brightness in the 'Custom 1' Picture Mode with HDR on. The Brightness is locked to max when HDR is enabled.

As is expected of most VA panels, the Gigabyte G34WQC has sub-par horizontal viewing angles. You lose image accuracy as soon as you move off-center, which isn't ideal for sharing content on your screen or playing co-op games. The Gigabyte M34WQ is a very similar display, but it uses an IPS panel and has much better viewing angles.

The vertical viewing angles are poor, making images look inaccurate if you have the screen mounted above eye level.

Our Gigabyte G34WQC has excellent gray uniformity; however, this can vary between units. The sides are a little darker, but there's almost no dirty screen effect.

Black uniformity is okay. There's visible backlight bleed along the top and bottom edges, which can be distracting in dark scenes.

Before calibration, the Gigabyte G34QC has decent accuracy, although this varies between individual units. Most colors and shades of gray are somewhat inaccurate, and it has a cold color temperature that gives the image a slight blueish tint. Gamma doesn't follow the target curve at all. Most scenes appear too bright, and very bright scenes are too dark.

After calibration, the Gigabyte G34WQC's accuracy is exceptional. The remaining color inaccuracies shouldn't be visible to the naked eye, and white balance is nearly perfect. The color temperature is much closer to our 6500K target. Gamma is much improved, but dark and bright scenes are over-brightened.

The Gigabyte G34WQC has an outstanding SDR color gamut. It covers the commonly-used sRGB color space almost entirely, and it has great coverage of the Adobe RGB color space used mostly in photo editing.

The SDR color volume is exceptional; however, it has some difficulty displaying very dark and saturated colors, even though it has a high contrast ratio.

The Gigabyte G34WQC has an okay HDR color gamut. It has decent coverage of the commonly-used DCI P3, but its coverage of the wider Rec. 2020 color space is mediocre. If you want a similar monitor with wider DCI P3 coverage, check out the ASUS TUF Gaming VG34VQL1B or the Dell S3422DWG.

The HDR color volume is okay, mainly limited by the HDR color gamut.

Good reflection handling. The matte anti-reflective coating works well in reducing the intensity of reflected lights. Combined with the screen's high peak brightness, you shouldn't have any visibility issues.

Good text clarity. Enabling Windows ClearType (top photo) makes the letters look bolder and improves the appearance of diagonal lines, such as on the R and N.

The Gigabyte G34WQC has exceptional gradient handling. There's only a little bit of banding in the grays and greens. This monitor is advertised as having an 8-bit panel; however, it's identified as a 10-bit panel in the NVIDIA control panel and the Radeon app. It may be 8-bit+FRC, but we're unable to confirm it.

The refresh rate is limited to 100Hz over HDMI. If you want something with a slightly higher 165Hz refresh rate, then check out the Samsung Odyssey G5 LC34G55T.

The Gigabyte G34WQC supports FreeSync natively to reduce screen tearing when gaming. It's compatible with NVIDIA's G-SYNC as well, but it only works over a DisplayPort connection.

Update 12/03/2020: We mistakenly indicated the dark total response time as 185.1ms instead of 18.1ms. It has been fixed and the score has been adjusted accordingly.

The Gigabyte G34WQC has a great response time at its max refresh rate, but just like the Gigabyte G32QC, there's black smearing behind fast-moving objects. The best overdrive setting is 'Balance', as it provides the best performance with minimal overshoot. If you want an ultrawide gaming monitor with better response time, check out the LG 34GP83A-B.

The response time at 60Hz is good. The best overdrive setting is again 'Balance' because the 'Picture Quality' option is slower and results in a blurrier image, and the 'Speed' option has too much overshoot. If you want an ultrawide gaming monitor with a faster 60Hz response time, check out the Dell S3422DWG.

The Gigabyte G34WQC has an optional Black Frame Insertion feature to improve motion clarity called 'Aim Stabilizer'. There's less black smearing when enabled, but it causes slight image duplication. It isn't usable while VRR is active, and it locks the overdrive setting to 'Speed'. You can see the 120Hz graph here.

The backlight is entirely flicker-free, which minimizes image duplication and can help reduce eye strain.

The Gigabyte G34WQC has an exceptionally low input lag that results in an extremely responsive gaming experience, and enabling BFI or VRR doesn't add any noticeable latency.

The Gigabyte G34WQC has an ultrawide screen that provides an immersive gaming experience and lets you work comfortably with multiple windows opened side-by-side. It has the same pixel density as a 27 inch, 16:9 monitor with a 1440p resolution, so images and text look sharp. Note that not all games support an ultrawide format, which means that you may see black bars at the sides, or the image might be stretched to fill the screen.

There aren't any USB inputs, but if you want something that does, consider the AOC CU34G2X.

Unfortunately, this monitor doesn't fully work properly with macOS. VRR doesn't work at all on the desktop, and in-game, it causes the screen to flicker constantly. HDR doesn't work properly either, as colors appear too cold, and the image doesn't look good. It doesn't recover from sleep properly, either, as windows sometimes didn't go back to their original position.

The Gigabyte G34WQC has many additional features, including:

• Crosshair: Adds a virtual crosshair on the screen.
• Timer: Puts a timer on the screen.
• Frame rate counter: Shows current frame rate.
• Black Stabilizer: Helps make objects more visible in dark scenes.
• Picture-in-Picture/Picture-by-Picture: Lets you display two input sources at once, which can be useful for those working on two computers or using another computer for streaming.

Unlike the Gigabyte G32QC, this monitor isn't compatible with Gigabyte's OSD sidekick software, which allows you to control the monitor's settings using a mouse and keyboard. It also doesn't have the keyboard, video, and mouse switch found on Gigabyte's M Series monitors, including the Gigabyte M34WQ.
