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.

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 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 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.
