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.

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.

Design
Back
Wall Mount VESA 100x100

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.

Build Quality

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 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.

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.

Our measurement of the DCI P3 coverage is lower than the advertised 90% due to how we measure it. We measure it by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors to the DCI P3 primaries. This results in a lower but arguably more accurate measurement.

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 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. We're unable to measure the input lag with 10-bit HDR because we lack the tools to measure it with HDR over a DisplayPort connection. Over HDMI, we can only get 100Hz if we use 8-bit color coding or 60Hz at 10-bit. That said, we don't expect the latency to change much with HDR enabled.

If someone comes across a different type of panel or their Gigabyte G34WQC doesn't correspond to our review, let us know and we'll update the review. Note that some tests, such as gray uniformity, may vary between individual units.

Our unit of the Gigabyte G334WQC 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.

AOC CU34G2X

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. Even though the Gigabyte is certified by AMD to have native FreeSync support, FreeSync still works on the AOC, and G-SYNC works on both. 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.

ASUS TUF Gaming VG34VQL1B

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.

Gigabyte G32QC

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.

Gigabyte M27Q

The Gigabyte G34WQC and the Gigabyte M27Q 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.

Samsung Odyssey G5 LC34G55T

The Gigabyte G34WQC and the Samsung Odyssey G5 LC34G55T 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.

LG 34GN850-B

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.

Acer Nitro XV340CK Pbmiipphzx

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.

Samsung Odyssey G9

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.

Nixeus EDG 34

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.
