Viewing Angles, Uniformity, Response And Lag
To learn how we measure screen uniformity, please click here.
The Z27q's off-axis performance is typical of modern IPS panels. Viewing the image at 45 degrees to the side results in a moderate light falloff and a slight color shift to green and red. The same is true when viewed from the top down. Detail is well-preserved even in the darkest steps so image integrity should be acceptable to viewers not sitting in the center seat.
Screen Uniformity: Luminance
In the ANSI contrast test we noted two hotspots in the upper-left and lower-right corners. Those same areas affect the Z27q's black field uniformity. 13.77 percent isn't a bad result but other screens score better. In practice it doesn't qualify as true light bleed but in a dark environment you can just make out the extra brightness in those two corners.
Here's the white field measurement.
The white field result is considerably better with no visible issues whatsoever. In fact, once the field patterns exceed 10 percent those hotspots we mentioned become completely invisible. The Z27q doesn't include any uniformity compensation but we'd say given the performance of our sample, it's not needed.
Screen Uniformity: Color
Color uniformity is equally competent and exhibits no visible tinting anywhere on the screen. Smooth tones are all you'll see at every brightness level including the 80 percent mark we test at.
Pixel Response And Input Lag
Please click here to read up on our pixel response and input lag testing procedures.
Panel response is quicker than we'd expect given the high pixel count. We don't expect to see much gaming on this monitor at its native resolution, but full-motion video exhibits far less motion blur than many other displays.
Here are the lag results.
Input lag is also quite impressive. We credit some of that to the AMD FirePro graphics card but this is a pretty snappy panel considering how much processing is going on. It's one of the faster IPS screens we've tested at any resolution.
27" is too damn small! (So is anything under 34" for 4 and 5k screens.)
This is a professional monitor and one of the few 5k screens on the market. Power consumption does not matter.
I have a 34 inch Dell Monitor, 21:9,, rather than wait until the GPUs will become powerful enough i simply temporarily switched to playing AAA games on the XBox One. So i have the monitor for general PC activity and play Xbox on it as well.
Realistically it is simply too much to drop all that money on the monitor and a GPU, of the two i think GPU can wait.
That is one of my perennial questions. How to verify that when looking at a monitor's specifications. Can you provide any guidance in that area? I lnow that 10-bit (or 8-bit) is important for the entire path of image production, but I do not always know how to ensure that.
