We ran our grayscale, gamma and color tests in the GNV34BDE’s Standard picture mode, which makes all image controls available. The only gamut available is the native one, DCI-P3.
Grayscale and Gamma Tracking
We describe grayscale and gamma tests in detail here.
Though the GNV34BDE default color temp is called Warm, our tests showed it to be too blue. The error is visible from 40% brightness and up and made the picture look a little flat. The average Delta E (dE) of 4.5917 is a little higher than most monitors in this class. On the other hand, gamma tracked at the 2.2 setting. Aside from a slight bump (too dark) at 90% brightness, gamma stayed right on the reference line.
Calibration (second chart above) made a visible improvement in the Viotek’s white point. Now, all errors are below the visible threshold. Gamma was nearly unchanged from before. This is excellent performance, especially for the price.
A 4.59dE was a decent default grayscale error score perhaps five or six years ago. Today’s monitors come from the factory closer to the D65 (6500K) standard. The GNV34BDE is merely okay without adjustment. We strongly recommend calibration using our recommended settings.
Gamma tracking was quite good in either case. The 2.2 preset measured correctly with only the aforementioned bump at 90% brightness. The range of values was tight at 0.18. Though that put the Viotek in last place in our comparison, it’s up against very stiff competition. A 0.45% deviation from 2.2 (actual value is 2.19) means you can expect solid image depth and good color saturation tracking.
Color Gamut Accuracy

Since the GNV34BDE’s only available color gamut is DCI-P3, we tested against that standard. By default, the magenta and cyan hues were off-target because of the grayscale errors we recorded. Red saturation was correct at the 100% mark but a bit under at 20-80%. Additionally, green fell short across the board.
Calibration (see our recommended settings) fixed the hue errors and improved the red saturation points. Blue and magenta were still slightly under-saturated, but this wasn’t visible to the naked eye. The grayscale tweaks took all color errors below the visible threshold.
All the monitors here delivered good color gamut accuracy, so the Viotek’s fourth place finish isn;t bad. 1.99dE is a low average error, especially considering the GNV34DBE’s price tag. As a DCI monitor, it competes with some of the best. There’s no sRGB mode available, but most users will appreciate the bonus color in their SDR games and content.
Our test showed the GNV34DBE offers 81.69% coverage of DCI-P3, which is slightly above-average for the group. sRGB coverage is over 120%, so you’ll need a software profile to engage in color-critical work. For gaming and entertainment, however, we were quite satisfied with the GNV34BDE’s color and gamut volume.

Man is that one ugly stand.... I think is is an awesome monitor for the price but I could not look at the stand ......aaarrrggghhhh!!!!:LOL:Reply
I looked for a better place to post this but couldn't find one:Reply
The Tom's Hardware website uses a lot of CPU in Firefox. I don't know why it doesn't in Chrome or Edge. The forums are fine also. But if I have the homepage or any article/review open in Firefox, it uses about 30% of my CPU just sitting there.
"HDR" at 350 nits? I don't think so. That doesn't even qualify as the not-really HDR 400 spec. This is NOT an HDR monitor folks.Reply
I agree that could look a bit dull if was a TV but while 500+ nits would be ideal you are not going to get it at $450, many even more expensive ones are only 300-400 nits. This is bang for your buck and not top of the tree for sure.techrabbit2015 said:"HDR" at 350 nits? I don't think so. That doesn't even qualify as the not-really HDR 400 spec.

"GTG" @ 4mS? I don't think so!Reply
Kudos should only be awarded to GTG@1mS. Otherwise, FreeSync (@144hz) is for naught.
Agreed this is not an HDR monitor. It's an "HDR-ready" or "HDR-compatible" monitor. I.e., it can accept and decode the 10-bit signal, but it's going to downsample it to 8-bit. And this is not news; this deceptive marketing ploy by manufacturers has been covered (and criticized, including from within the TV and monitor industry) for some time now: https://web.archive.org/web/20180612121214/http://www.avhub.com.au/news/sound-image/what-does-hdr-compatible-mean-461032Reply
That said, the price is great for the feature set. I won't be getting this one myself, because a non-adjustable "chopsticks" stand will have to be replaced by a proper VESA one, which jacks the total cost up into the range of an at least marginally better monitor.
I bought this monitor to replace my triple screen set up. Much better picture visually, even without calibration. After calibration, this screen is one of the best I have owned out of dozens. I honestly don't mind the stand as on my black monitor riser I can barely see it anyway. My one gripe- my display port cable hangs from the input and there is nowhere to hide it. Ugh. Awesome purchase anyway. Oh, and I don't care about HDR, especially at this price.Reply
Just curious, what calibration settings did you use? In the article it says multiple times, we highly recommend using our calibration settings. But I'm unsure what those settings actually are? Besides the chart that shows settings for red, green, and blue, and brightness levels I don't see any additional settings for black levels, sharpness, etc. Did i miss somewhere in the article where it outlines all calibration settings? Thanks for your help!maestro0428 said:I bought this monitor to replace my triple screen set up. Much better picture visually, even without calibration.

I don't think they listed all of the settings. I adjusted the best I could according to my room lighting manually. If you are really worried about the color, I wouldn't, even before I adjusted it, I didn't see any issues at all, get a color meter.Reply
If you are just gaming and watching content, adjust to your personal liking in your room. If you are a serious photo pro, you may want to spend more.
