The Gigabyte G34WQC isn’t a great monitor for sharing. At 45 degrees to the sides, light falls off by around 40%, and the color shifts to green. We can see a similar result in the vertical plane with a further loss of detail as gamma becomes lower. You’ll want to sit front and center for the best image quality. At 2-3 feet away head on there are no issues visible.

Screen Uniformity

The top four monitors here all fall under 10% average deviation, meaning they have no visible bleed, glow or hotspots. The G34WQC is exceptional with a 7.67% score. Our sample looked perfect when viewing full-field test patterns in a dark room. There were no color uniformity issues either.

The G34WQC breezed through our speed tests, showing typical performance for a 144 Hz monitor. 7ms is a low enough screen draw time that motion blur can barely be seen. Gigabyte’s excellent overdrive implementation reduces that blur even more. With 27ms of total control lag, competitive gamers won’t have any problem keeping up with their opponents. We observed smooth motion with no stutter or hesitation to either mouse or keyboard inputs.

    Thanks for a first review of this screen, great to hear that Gigabyte has done well with overdrive settings and input lag is fine. Moreover 85% DCI-P3 with an average calibration is good.

    However, many users report flickering with VRR turned on both in Freesync and G-sync. Have you experience any and which GPUs have you been using?

    VA panels have a major issue with ghosting or horrible pixel blur at fast motion Nano IPS is still a better looking panel all day everyday, I just wish they would fix the OLED issues of burn in images, and progress into Gaming monitors with 240hz + I will never go less than a 240hz at 1440p specially now that there are cards that can push that at ultra or high settings. GO RX series :). and HP Omen x27 240hz has dci-p3 of 90% on a TN panel and has been out for over a year this Gigabyte is GARBO a lot of games don't natively support ultra wide very niche specially in high end gaming or competition gaming.

    Thank you for the review! I've been waiting a few years for a monitor with these specs - 3440x1440, >100Hz, HDR, Freesync and GSync compatible, curved screen, and most importantly under $400. I thought I'd be waiting a few more years but it looks like they did a good job with this one on top of having the characteristics I was looking for.

    How does this compare to the Nixeus EDG34? Specs look very similar.

    Can you confirm that HDR and Freesync/Gsync work at 144hz simultaneously ?

    We were also able to engage HDR with both FreeSync and G-Sync (unofficially) at 144 Hz through DisplayPort. If you connect via HDMI, you'll be limited to a 100 Hz refresh rate

    So, it's now December 2020. Is the Dell S3220DGF "STILL" the best gaming monitor? Christian Eberle what do you think? Dell or Gigabyte?

    Also in your reviews, is there a benefit to either of these monitors using consoles vs PC? Both older xbox one x or the new ones Ps5 and/or xbox series x? Which one makes better since if you will play both console and PC?

    Would it be safe to say this outperforms Viotek GNV34DBE for the same price?!

    The Gigabyte G34WQC 34-inch ultrawide gaming monitor sells for a surprisingly low price. With 144Hz, HDR and more, it sets a high bar for the performance/price ratio.

    I'm confused on your part around Calibration Settings. You provide different brightness based on the nits. How the user supposed to know which one should be used? Please advise and thank you in advance.

    This still doesn't have anywhere near the amount of brightness or contrast a proper HDR display has. My pg35vq breaks 26000:1 contrast ratio and 1100 nits. It was pricey but now that miniled panels are coming this year I expect more affordable FALD panels will start appearing.

    There's a handful of VA panels that have very fast response times even with dark transitions like the Odyssey G7 and Asus pg35vq.

    I purchased this monitor largely on the basis of this review. I'm incredibly happy with my purchase. However, when my computer goes to sleep the monitor starts to cycle through full-screen colors. Does anyone else see this behavior? No other monitor I have does this, and Gigabyte "help" hasn't been able to provide an answer. It seems as though the person I've been conversing with doesn't have very strong English language skills so we keep talking past one another.
    If anyone has this monitor and can either confirm that this is normal or that their monitor doesn't behave this way I would appreciate it. Even better would be if someone knows how to turn this off!
