Color Gamut And Performance

Don’t be too alarmed by the above chart. It’s only the beginning of our story about the XL2730Z’s color gamut. We’re showing you the default FPS1 mode to demonstrate why it’s not the best choice. There are major hue errors in the secondary colors (cyan, magenta, yellow). Red is mostly under-saturated and blue is over-saturated at every level.
The Standard mode offers far better color accuracy, as shown here. Luminance levels are nearly perfect. Blue is properly lowered to compensate for that oversaturated primary. Our only beef is that red doesn’t track its saturation points particularly well. For that, we thought we’d try and change the gamma preset.
Well, we improved the red and blue saturation points. But now color luminance is lowered, which makes the image a tad dull. We’ll venture outside of our normal calibration procedure and try the Color Vibrance slider.
While the average DeltaE value is a tad higher, we prefer the look of this last chart. All color saturations are close to their targets and luminance values are just slightly elevated. The resulting image is nicely saturated without any detail clipping or unnatural coloration. This was achieved by returning the gamma preset to 2 and upping the Color Vibrance slider to 11.
Now we return to the comparison group:
The numerical result is represented by the third chart above, the one with slightly-low luminance values. Even though red and blue saturation are a little off-target, the average DeltaE error is lower. We still prefer the final chart, and that one has an error of only 2.21dE.
Gamut Volume: Adobe RGB 1998 And sRGB
Thanks to an over-saturated blue primary, the XL2730Z exceeds 100 percent of the sRGB gamut volume. To take advantage of this bonus color, you have to match your camera and printer. As far as gaming monitors go, though, this metric is less important.

I don't understand why the price is so high. The only things I see that are different (in any meaningful way) from the Acer XG270HU (which I have, and am a fan of) is hight adjustment and an external puck to load configurable screen settings. (that is pretty cool though)Reply
The Acer also doesn't have the raised bezel that is actually about 8mm (Top, Left and Right)
The Benq looks like a good monitor, I just don't see what justifies the premium price.
I'll wait for 29" 21:9 1440p instead, the only option available is curved, which is pricey, I don't see the curvation worth the extra cost... FreeSync is a plus but this will drive the cost up again ( to have a 144Hz panel at that resolution )... and please add a USB 3.1 hub with 2x Type-A & 2x Type-C portsReply
i may have missed it in the article, but what is the range of frames freesync covers on this monitor?Reply
i may have missed it in the article, but what is the range of frames freesync covers on this monitor?First thing I was thinking of is FreeSync Range , and I double checked the article and there is no mention of it at all! I think the writer is not well informed regarding FreeSync - GSync Range.
The frame-rate range is 40-144Hz.Reply
This was a good article for a monitor review....it was a very bad article for one of the first Freesync monitors to be released. Many of us wanted more info on that and you acted like all monitors are the same as long as the tech works...that is just not true. Please add more about the Freesync tech, how it worked and what it's limitations were.Reply
Why does the author not add a comparison to the Acer XB270HU? Instead they make reference to the ROG Swift? At ~$740, the XB270HU offers 1440p, 144hz, and Gsync on an IPS panel and is definitely at the top of my list at this price point. Could Toms please add info on the Acer panel to this review?Reply
Christian, I sent you an email about Version 4 firmware for the previous monitor you reviewed--the XL2720Z.Reply
And "Area" is the same thing as "strobe phase" is on the older Z series.
He says it's 40-144, but has that been tested? Or is that just the normal statement? Recall plenty of FS monitors state a range and then the panel won't oblige once it was properly tested.Reply
That's the refresh rate capability, NOT the blur reduction rate capability. The older Z series can't even single strobe at 50hz without a Vertical Total tweak which tricks the scaler into using 60hz backlight pulse widths (if you try single strobe at 50hz without it, the backlight becomes overdriven with voltage and the current makes the monitor reset from overcurrent protection.Reply
It can "double strobe" at 50hz and 60hz but that's only because the single strobe option is missing from the service menu (it was there in all of the previous benq blur reduction monitors including the 2430T).
