Measurement And Calibration Methodology: How We Test
To measure and calibrate monitors, we use an i1Pro spectrophotometer and version 5.1.2 of SpectraCal’s CalMAN software.
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 stereo glasses.
The i1Pro 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, we’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).
I'd guess it's merely a chicken/egg issue - people won't buy high-res screens until they are cheap and they won't be cheap until lots of people buy them.
That is the beauty of Capitalism. The rich have more than enough money, and will be more likely to spend money on something new. Companies wanting to maximize profits, try and make production cheaper. When company X makes production cheaper than company Y, then Y undercuts X and yay cheaper products.
Aside from the fact that compared to the QHD monitors you can pick up for under $300 this is garbage, it's just a silly format. Dated resolution on a cheap panel that's too big.
I understand where you are come from bot not every is looking for an extreme like that. If I had one of those I wouldn't complain. The monitor I currently have is better than this one, but that doesn't mean I wouldn't use this monitor. Tom's I believe is just trying to cater to everyone they can. So i say this kind of review is good for everyone.
Why on earth would anyone want 1920x1080 on a screen 27 inches diagonal? Are you looking for pot holes between the pixels?
The reason I say this is, I work with media all day, We currently create, edit and produce 4k video and store it for transfer to quad layer blu-ray disc's (200GB).
Also, if you use any digital camera over 8MP, you will get close to a 1:1 pixel ratio at 4K resolutions.
We want to see a continuous image and seeing the gaps between the pixels is distracting.
24 inch monitors should have a minimum 4k pixel resolution, 708 might be able to get away with 4k on a 27 inch, but 8k would be better.
Now, lets look at the other side, How much would a 24 inch 1920x1080 flat trinitron cost you back in the day? $6,000 ? $12,000?
