Screen measurement with probe
Screen measurements
We begin our test with the test of the panel and in order to know the colorimetric quality of this screen out of box, we carried out measurements of the screen.
For this test, we put the graphics card in discrete mode, which allows to have more adjustment for the screen and to pass it in 10bit via the Nvidia control panel. The measurements are better in this mode and it is possible to have a better rendering after calibration.
This one has been tested on DisplayCal following 51 color patches with the sRGB profile as target.
As we can see, the calibration is quite disappointing, we have 6500K for 6500K expected, which is in the specs. The delta E is more than 4% of average deviation and 9.31% at the maximum.
As for brightness, the screen can go up to 852cd/m² with a contrast ratio around 11188:1.
The gamut is :
- 99.5% of sRGB
- 97.8% of Adobe RGB
- 98,6 % of DCI P3
After calibration we have 6300K for 6500K expected, which is in the specs. The delta E is contained to less than 0.6% average deviation and 1.36% at the maximum.
As for brightness, the screen can go up to 800cd/m² with a contrast ratio around 9777:1.
We are therefore in SDR on a particularly good slab. The contrast ratio offered by the mini-LED technology makes this screen almost perfect.
Let’s move on to HDR mode. Here we have 6400K for 6500K expected, which is in the specs. The delta E is contained to less than 3.6% average deviation and 8% at the maximum.
As for brightness, the screen can go up to 933cd/m² with a contrast ratio around 11904:1.
When calibrated in HDR, we have 6500K for 6500K expected, which is in the specs. The delta E is contained to less than 2.9% average deviation and 6.6% maximum.
As for brightness, the screen can go up to 965cd/m² with a contrast ratio around 7730:1.
Even calibrated, the HDR mode does not allow to have a very accurate image in colors. It will be necessary to disable it for photo editing and rather bet on the SDR 10 bits mode.
As for the reflectance of the screen, we have a matte slab, a good choice for use in a bright environment. The grain is very low or even invisible, so the sharpness is also very good for photography.
