ColorChecker or also color fidelity
Again, the smaller the Delta E, the better. First and foremost, it is important how well or poorly a monitor is received by the customer. This refers to the performance “out of the box”. Both under the generic term: Gray Scale and for the topic of color fidelity (ColorChecker). I measure the color fidelity according to DisplayCal ColorChecker SG once uncalibrated and calibrated. All further information you can see in the following pictures.
This is a very good result. With that, you could get started right away. An Average Delta E smaller than 1 is of course a result that can only be achieved with a calibration.
Sorry, but the page is long and cannot be displayed any other way.
But maybe this representation is enough for you? Here you can see the deviation of the colors in the gamut. Wait, I’ll try something, maybe the link will work. If so, please provide feedback via forum. Thank you!
Display Uniformity
This shows how evenly the panel is illuminated over the entire surface. I measure the brightness at 25 points in four steps (25 to 100 %). I perform this measurement – for the sake of better comparability – after calibrating the display to D65, 200 nits and gamma 2.2. The same conditions should prevail here for all monitors. A deviation Delta E > 4 can actually be perceived. However, it is not yet disturbing.
Not particularly good, but not really bad either. Almost typical for an IPS panel (IPS Glow). When you look at the display, it still looks well united. There is not much more to say about it.
SDR (Standard Dynamic Range) vs. HDR (High Dynamic Range)
Anyone sitting at a PC right now will most likely not have their monitor or Windows settings set to HDR. Thus, as always, we are in SDR mode. This is not a big deal, because you need several prerequisites to really enjoy HDR.
First, the content must be mastered in HDR. There are various differences here alone. Thus, there is HDR 10, HDR 10+, Hybrid Log Gamma, Dolby Vision and Dolby Vision IQ. To go into detail about all these formats now would be the last straw. I link you something, who wants to know more about it: Click(Here),(Here) or also(Here)

Secondly: And here the circle closes to the first part concerning the monitor basics. You need a monitor that can actually reproduce HDR content. Keyword OLED or Full Array Local Dimming. Unfortunately, a funny HDR-400 or HDR-600 sticker is not enough. Likewise, the color depth 8 vs. 10 vs. 12 bits of the panel as well as the topic of chorma subsampling (color subsampling) also play a role here. You could do a separate article on the subject of color subsampling. I’ll spare myself that and you please have a look at this: Link

Third, a wide gamut display with a DCI-P3 color space coverage >90% or at least 70% Rec. 2020 Color Space Coverage. The gamut is still the smallest challenge.
If you meet the three requirements, you will get a much better picture, video or game with HDR. High contrast paired with light and shadow details with extremely good image sharpness. If you haven’t experienced it yet, I highly recommend it. The SDR mode can’t keep up with that. On the other hand, the amount of data in SDR is significantly lower. Streaming a UHD Dolby Vision + Dolby Atmos movie pushes my 25 Mbit line to the limit. There is nothing more to do here – online gambling on the side is not possible.
I will leave the topic of EOTF(Electro-Optical Transfer Function) untouched for the time being. For one thing, I can’t measure that at all at this point, and for another, you only need it in conjunction with HDR.but now I’m coming to the end. Last page please!
