By default, the monitor has 100% brightness and 50% contrast. I reduced them both to 20% to achieve 100nit white brightness. The image quality is subjectively good. The monitor has good viewing angles (for a TN+Film matrix) and reproduces color gradients without apparent defects.
The gamma curves are not ideal (which you can hardly expect from a monitor of this class), but look well and betray no critical problems. They still look well when the brightness and contrast settings are reduced below their default values: dark tones are always reproduced in full.
It’s worse with the response time parameter: although it is about 10 milliseconds at the minimum, the maximum is as high as over 30 milliseconds.
The color temperature setup isn’t perfect, either. You have seen worse setup in above-described models, but the discrepancy of a couple of thousand degrees is somewhat disappointing after the accurately set-up monitors from Sony. On the other hand, the color temperature corresponds to the declared values. That is, if you choose “5000K” in the menu, you do get a warm image on the screen.
And last go the brightness measurements. Here the monitor shows its best, boasting a really good contrast ratio. It is unfortunately lower at the low brightness of the screen, yet remains acceptable anyway.
So, the VG712s is no better or worse than most of the other monitors included in this review. It doesn’t have any serious defects, but it can’t boast anything exceptional, either. The matrix is rather slow and the color reproduction might have been better set up. So you should choose basing on the price of the monitor relative to its competitors as well as on your own preferences concerning the appearance of your PC peripherals.
