1. "Delta-E" being higher than 4 even after professionally performed custom calibration, still stays higher than 4 even in the best case scenario.
2. Heavily leaking backlight.
3. No pivot/shrivel/turning/portrait.
4. No VMIS support (a.k.a. VESA Mounting).
5. 60Hz, but only through DisplayPort.
6. If using two cards (doesn't matter if SLI or CFX) - automatically goes into 1440p.
7. 30Hz if HDMI.
8. "Crystalline Effect" in full bloom.
9. viewing angels for a TN (especially if you consider it's 2014 and not early 2000s), even UXGA-type TN panels from mid-2005 are better, I am you not.
10. PWM all the way.
11. Dynamic contrast doesn't work (it's a problem of many modern panels, even actually very good and high quality models, but considering this particular monitor's price, this is twice as hilarious and sad at the same time).
12. "One billion colors" my ass.
13. Static contrast ratio is actually 827:1 at the best case scenario (after professionally performed custom calibration) and never goes higher, no matter how hard our lab tried. "1000:1"? PUH-LEASE.
Testing the monitor here at home and here are some of my thoughts to those above:
1. Haven't tested it. I have found that the monitor requires proper calibration to look decent. Factory settings are poor.
2. You may have a bad sample, BLB is very minimal on my sample.
3. True, but that info is known before you even purchase the monitor.
4. Same as above.
5. Just like every other 4K monitor on the planet, no reason to complain.
6. Sounds like user error, no issue here.
7. HDMI 1.4 spec cannot run 4K at 60 Hz. There are no HDMI 2.0 GPU's, no reason to complain.
8. It actually has the same industry standard semi-gloss AR film that is widely praised and becoming more common on modern displays. "Crystalline Effect" is almost non-existent.
9. All TN panels have poor viewing angles and known before purchase. Due to the panels larger size, it will "appear" to have worse viewing angles than smaller TN panels. To properly view a TN panel, your eyesight should be aligned with the top of the monitor bezel and eyes should naturally gaze down. Harder to accomplish that on a larger TN (especially one with no height adjustment).
10. Incorrect. It has PWM 0-29 brightness. 30-100 brightness either goes DC voltage, or the frequency becomes so high that it doesn't matter.
11. I haven't found a monitor yet in which you would want to turn on dynamic contrast. Just a marketing gimmick.
12. Panel actually does fairly well in dithering tests. Stating how many colors the panel can reproduce does not equal the level of color saturation colors that "pop".
13. Contrast ratio, just like virtually all TN and IPS panels is less than 1000:1 and considered poor. 827:1 is not actually terrible for a TN. VA panels are the only place you are going to find truly great contrast ratios.
I will add my own: IPS glow. There is none!
