Uncalibrated – Maximum Backlight Level
The C27G2Z is bright enough for any indoor environment or intended use. Only the most sunlit room will need a peak level of over 350 nits. I noted a slightly higher level when using the HDR emulation of 373 nits. That is a tiny, almost imperceptible difference.
With super low black levels, the C27G2Z cracks the 3,000:1 contrast barrier with a 3,205.6:1 score. In this group, only the Dell boasts better and only by an infinitesimal amount. You can see that the IPS screens are strong performers relative to that technology but don’t even come close to VA in contrast. This is a difference that can easily be seen in actual content.
After Calibration to 200 nits
Calibration has little effect on the C27G2Z’s contrast, which is good. I had to lower the contrast slider three clicks to correct the 100% grayscale step, which bodes well. It is well ahead of even the very best premium IPS monitors in this test.
Again, the IPS panels here do well in the ANSI test, but the Dell and AOC are far superior. Contrast is king and unless you put an OLED on your desktop, VA is the best way to achieve maximum image depth with true black levels and saturated color.
