Measurement And Calibration Methodology: How We Test
To measure and calibrate monitors, we use an i1Pro spectrophotometer, a Spectracal C6 colorimeter, and version 22.214.171.1244 of SpectraCal’s CalMAN software.
The i1Pro is very accurate and consistent measuring color on all types of displays, regardless of the backlight technology used. When we just need a luminance value, the C6 works better, especially in low light.
For patterns, we employ an AccuPel DVG-5000 video signal generator. This approach removes video cards and drivers from the signal chain, allowing the display to receive true reference patterns. Connections are made via HDMI.
The AccuPel DVG-5000 is capable of generating all types of video signals at any resolution and refresh rate up to 1920x1080 at 60 Hz. It can also display motion patterns to evaluate a monitor's video processing capabilities, with 3D patterns available in every format. This allows us to measure color and grayscale performance, crosstalk, and ghosting in 3D content via the 3D glasses.
The i1Pro or C6 is placed at the center of the screen (unless we’re measuring uniformity) and sealed against it to block out any ambient light. The AccuPel pattern generator (bottom-left) is controlled via USB by CalMAN, which is running on the Dell XPS laptop on the right.
Our version of CalMAN Ultimate allows me to design all of the screens and workflows to best suit the purpose at hand. To that end, I’ve created a display review workflow from scratch. This way, we can be sure and collect all the necessary data with a concise and efficient set of measurements.
The charts show us the RGB levels, gamma response, and Delta E error for every brightness point from zero to 100 percent. The table shows us the raw data for each measurement. And the area in the upper-left tells us luminance, average gamma, Delta E, and contrast ratio. The individual charts can be copied to the Windows clipboard to easily create graphics for our reviews.
Every primary and secondary color is measured at 20-, 40-, 60-, 80-, and 100-percent saturation. The color saturation level is simply the distance from the white point on the CIE chart. You can see the targets moving out from white in a straight line. The further a point is from center, the greater the saturation until you hit 100 percent at the edge of the gamut triangle. This shows us the display’s response at a cross-section of color points. Many monitors score well when only the 100-percent saturations are measured. Hitting the targets at the lower saturations is more difficult, and factors into our average Delta E value (which explains why our Delta E values are sometimes higher than those reported by other publications).
It's still an interim monitor, though. What I really want is a large affordable WQHD or UHD IPS gaming monitor.
especially on a large 27" screen?
In the early 2000s it might have been ok to have such resolution, but nowadays
it is no longer usable. Even for a 24" screen the minimal resolution is
Until they are not making these 27" screens to have more pixels, they are not
seeing any cash out of me. I rather buy el-cheapo monitors from Ebay as a mail
order from Korea.
Monitor manufacturers, please stop living in the 80s and stop hustling us with
sometimes I feel like nobody is listening... or just trying to sell me a bridge for the low low.
decent review, but if youve got the gpu for 144Hz. 2160p @60 is just a cootie shot away
What on earth have happened? Why did prices go up, and resolution went down?
Why are there no 30" 2560x1600 TN panels out there for gamers for 700 Euros?
This monitor is made for gaming, true gamers don't care a grate deal about resolution. We are in it for the refresh rates and the response time. Ive been gaming on a old CRT monitor till last year with a change to the Asus VG248QE. Even though its still much slower than my old CRT it works. I have 2 computers 1 for gaming and one for everyday and video work. Gaming machine is set up around a single R9 290X, 4770K, and a Asus VG monitor. My other computer is a crossfired 295s, 3930K, and 3 IPS 4k monitors.
A single card is better for latency, 4770K is more than enough to push data to the 290X and the monitor has a fast refresh rate. Its better at gaming than my extremely high dollar build. Peripherals are set up differently as you can imagine gaming computer has razer and a 7.1 headset. The other is mostly set up for 2.1 but i do have a 7.1 headset for room sound.
"This monitor is made for gaming, true gamers don't care a grate deal about resolution"
You meant, online multiplayer gamers don't care a grate deal about resolution.
I prefer to play single-player FPS, where I do want to have all the eye candy,
and I want to see the vegetation, desert, sky etc. The only advantage of a PC is
that it can provide better graphics, that is the main point.
Otherwise I could just go out, buy an 1080p TV, a Crapbox1, Crapbox360, or PlayStopper 4, and game on that thing in 1080p.
I think monitor technology is not moving forward (in fact moving backwards) exactly because people are happy to buy their 1080p crap for 500 Euros.
In the early 2000s CRTs were still the standard. 4:3 was the standard aspect ratio. There were no 1080p LCD monitors let alone large 1080p LCD monitors, and I paid ~$1200(NZD) for a 17" 1280x1024@60Hz (16ms) LCD display in 2003. That's how bad it was back then.
