The Gigabyte G34WQC is a great budget gaming monitor with an ultrawide screen. It has a 34 inch screen with a 21:9 aspect ratio, providing incredible immersion in video games and plenty of space for multitasking. It's well-suited for bright and dark rooms, as it gets bright enough to fight glare and can produce deep blacks. It has exceptionally low input lag, great response time, and a 144Hz refresh rate, delivering a gaming experience that feels smooth and responsive. It supports FreeSync natively and is compatible with NVIDIA's G-SYNC as well. Unfortunately, it has poor ergonomics and sub-par viewing angles, which isn't ideal if you want to share content or play co-op games. It gets decently bright in HDR, but the color gamut is somewhat limited.

Differences Between Sizes And Variants
We tested the 34-inch Gigabyte G34WQC, and it's the only size available. Gigabyte has also released an updated model, the G34WQC A, and while it has many of the same specs, the results from this review aren't valid for it because it's a different monitor.
| Model | Size | Panel Type | Resolution | Refresh rate |
|---|---|---|---|---|
| G34WQC | 34" | VA | 3440 x 1440 | 144Hz |
Our unit of the Gigabyte G34WQC was manufactured in August 2020; you can see the label here.
Compared To Other Monitors
The Gigabyte G34WQC is a great ultrawide gaming monitor, one of the best in its price range. The response time isn't as fast as the LG 34GN850-B's, but it's good enough to please most gamers. For more options, check out our recommendations for the best gaming monitors, the best ultrawide gaming monitors, and the best 144Hz monitors.
The Dell S3422DWG is a bit better than the Gigabyte G34WQC. The Dell has much better black uniformity, slightly better viewing angles, and a much better HDR color gamut. The Dell also has a slightly better response time and better connectivity, with a built-in USB hub. There's also a slight design difference, as the Gigabyte has a slightly more pronounced curve, which might bother some people.
The Gigabyte G34WQC and the Gigabyte M34WQ use different panel types, each with strengths and weaknesses, but the M34WQ is better overall for most users. The M34WQ has better ergonomics, much better viewing angles, a faster response time, and a great selection of additional features. The G34WQC is better for a dark room, as it has much better contrast.
The Gigabyte G34WQC and the Samsung Odyssey G5 C34G55T are two great gaming monitors. They both have a VA panel with a high contrast ratio but narrow viewing angles. The Samsung has a more aggressive curvature than the Gigabyte, but that comes down to personal preference. The Gigabyte is better for HDR content because it displays a wide color gamut and gets brighter. Also, it has a better stand as it allows for height adjustment. The Samsung has a higher 165Hz refresh compared to 144Hz on the Gigabyte, but overall, they deliver similar gaming performance.
The AOC CU34G2X and the Gigabyte G34WQC are both great gaming monitors. They have similar features with the same panel type and max refresh rate. The Gigabyte has a quicker response time, but black smear is visible on both. The Gigabyte is better to use in a well-lit room because it has better reflection handling and gets brighter. However, the AOC has four USB inputs, which the Gigabyte doesn't have, and its stand offers swivel adjustments.
The Gigabyte G34WQC and the Samsung Odyssey G5/G51C S27CG51 are different types of monitors with similar panel types. The Gigabyte is bigger with an ultrawide screen, offering a more immersive gaming experience. The Gigabyte also gets brighter, making it a better choice to use in a well-lit room. Motion handling is similar on both, but the Samsung has a slightly higher 165Hz refresh rate. One advantage that the Samsung model has is its improved ergonomics, making it easier to place in an ideal position.
The ASUS TUF Gaming VG34VQL1B is better than the Gigabyte G34WQC for most uses. The ASUS has a higher refresh rate of 165Hz compared to the Gigabyte's 144Hz, and it has better response times, especially in dark transitions. It also delivers a better HDR experience because it has a higher contrast ratio and a wider color gamut. Finally, the ASUS' stand allows for swivel adjustment, whereas the Gigabyte doesn't.
The LG 34GN850-B is a bit better than the Gigabyte G34WQC for most uses. The LG has wider viewing angles, better color accuracy out of the box, and significantly faster response time. However, the Gigabyte is better suited for dark rooms as it has a much higher contrast ratio to produce deep blacks.
The Gigabyte G34WQC and the HP OMEN 34c are similar monitors in specs and performance, but there are a few differences. The HP delivers slightly better image quality thanks to its improved image accuracy and wider range of colors in HDR. The HP also has a bit better motion handling, but each monitor has issues with that anyway. However, the Gigabyte is more versatile if you want to use it for console gaming as it downscales 4k signals, which the HP can't do.
The Gigabyte G34WQC and the Gigabyte G32QC are very similar with the main difference being that the G34WQC is ultrawide. The G34WQC has better gradient handling, a larger screen, and a higher pixel density that results in sharper images and text. However, the G32QC has a higher refresh rate of 165Hz, providing a slightly more responsive and smoother gaming experience.
The Acer Nitro XV340CK Pbmiipphzx is a bit better than the Gigabyte G34WQC. They both have the same size, resolution, and refresh rate, but the Acer has an IPS panel that provides much wider viewing angles. It also has better gradient handling and faster response time with less overshoot. On the other hand, the Gigabyte has a much higher contrast ratio, a better HDR color gamut, and gets brighter in SDR and HDR.
The Gigabyte G34WQC and the Gigabyte M27Q (rev. 1.0) are very different monitors. The G34WQC is an ultrawide monitor with a 21:9 aspect ratio, and it uses a VA panel, whereas the M27Q has a standard 16:9 aspect ratio and uses an IPS panel. The M27Q performs better for gaming because it has a higher refresh rate and faster response time. It can display a wide range of colors in HDR, and it offers more features, like a built-in KVM switch and a USB hub with USB-C input. On the other hand, the G34WQC is better suited for dark rooms, and its wider screen feels more immersive.
The Gigabyte G34WQC is a more versatile monitor than the LG 35WN65C-B. The Gigabyte is the better choice if you want to use it in a well-lit room as it gets much brighter, and if you also want to use it for gaming, it has a higher refresh rate and better motion handling. The Gigabyte also has a few extra features like a Picture-by-Picture mode built-in, but the LG has two USB ports, which the Gigabyte doesn't have.
The Gigabyte G34WQC and the Samsung Odyssey G9 score similarly overall, but there are many differences between them. The Gigabyte has a 21:9 aspect ratio, whereas the Samsung has a 32:9, which is much wider. The Samsung has a higher refresh rate of 240Hz, significantly higher HDR peak brightness, and faster response time, although with more overshoot. The Gigabyte has a higher contrast ratio and a Black Frame Insertion feature.
Overall, the Gigabyte G34WQC is much better than the Nixeus EDG 34. The Gigabyte has better color accuracy out of the box, better text clarity, and a Black Frame Insertion feature to improve motion clarity. Also, although it has poor ergonomics, they're still better than the Nixeus'. However, the Nixeus has a slightly higher contrast ratio to produce deeper blacks.
Test Results
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.
The accuracy before calibration is decent. It has an sRGB mode that locks the colors to the sRGB color space, but primary colors still don't reach their target as they're slightly undersaturated. The white balance is also off, meaning bright shades of gray, like white, are inaccurate. The color temperature is on the cold side, giving the image a blue tint, and gamma doesn't follow the sRGB curve well, meaning most images are brighter than intended.
Unfortunately, the sRGB mode locks most settings, including Overdrive and Black Equalizer. If you want to use these settings, the 'Custom 1' picture mode performs similarly, but some colors are oversaturated.
If you care about image accuracy and want an ultrawide monitor with better accuracy before calibration, then check out the HP OMEN 34c.
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 C34G55T.
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.

| Balance | Chart | Table | Photo |
| Speed | Chart | Table | Photo |
The Gigabyte G34WQC has a decent response time at its max refresh rate. There's some blur and smearing behind fast-moving objects, mainly due to its slow response time in dark transitions. The recommended overdrive setting of 'Speed' is quicker than 'Balance' and 'Picture Quality', but it has more overshoot. If you want an ultrawide gaming monitor with a better response time, check out the LG 34GP83A-B.
| Overdrive Setting | Response Time Chart | Response Time Tables | Motion Blur Photo |
| Picture Quality | Chart | Table | Photo |
| Balance | Chart | Table | Photo |
| Speed | Chart | Table | Photo |
The response time at 120Hz is okay. Once again there's smearing and motion blur. Unlike at the max refresh rate, the recommended overdrive setting is 'Balance' because 'Speed' has too much overshoot. This means you may need to change the overdrive setting if the frame rate of your game drops.
| Overdrive Setting | Response Time Chart | Response Time Tables | Motion Blur Photo |
| Picture Quality | Chart | Table | Photo |
| Balance | Chart | Table | Photo |
| Speed | Chart | Table | Photo |
The response time at 60Hz isn't bad. Like at 120Hz, 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.
The Gigabyte G34WQC works well with the PS5, but 4k @ 120Hz doesn't work because it doesn't support HDMI 2.1 bandwidth. As the PS5 doesn't support ultrawide gaming, you need to change the Display Mode setting in the monitor's OSD to 'Aspect' instead of 'Full' if you want it to display a 16:9 image with black bars on the sides.
The Gigabyte G34WQC works well with the Xbox Series X|S, but 1440p @ 120Hz doesn't work with any combination of settings. As the console doesn't support ultrawide gaming, you need to change the Display Mode setting in the monitor's OSD to 'Aspect' instead of 'Full' if you want it to display a 16:9 image with black bars on the sides.
Without any USB ports, you can't connect a mouse or keyboard or charge your devices. If you want something with USB inputs, check out the LG 35WN65C-B.
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.
