The monitor is equipped with a standard onscreen menu which differs from the previous model’s menu in one item only. It allows disabling the highlighting of the Power button. This is not a killer feature, of course, yet it is important for users who get annoyed at bright distracting LEDs in Power buttons.
The monitor has 100% brightness and 70% contrast by default. Choosing a higher contrast value results in a loss of light tones in the onscreen picture. To achieve a 100nit brightness of white I reduced the brightness setting to 51% and the contrast setting to 65%.
At the reduced contrast there appear barely visible stripes in color gradients. Dark tones never merge into one color whatever brightness/contrast settings you choose.
The monitor’s gamma curves are very close to the theoretical ones at the default settings, but sag at reduced contrast values. This is hard to see in practice, though, if you don’t know what to look for and cannot make a comparison with a calibrated monitor.
The color temperature setup is somewhat surprising. Among the three temperature modes (the user-defined mode coincides with the normal mode by default) there is no mode with a temperature of less than 7000K. Moreover, this temperature grows up more on gray. Thus, the monitor has accurately set-up color temperature modes, but each of them yields a very cold color.
Thanks to RTC, the monitor’s response time is very good. It is 3 milliseconds on average with a maximum of 5.6 milliseconds. The matrix is indeed very fast on any transition. It is among the fastest matrixes available today.
It is not without RTC errors, but within reasonable limits. An attentive user will spot image artifacts, I guess. The RTC error is 14.1% on average with a maximum of 43.7%. Transitions into dark colors are performed with a small or no error whereas transitions into lights are performed with a gross error. On the practical level it means that gray objects will be leaving a light trail when moving on a light background.
This monitor’s brightness and contrast parameters are a little better than average as TN matrixes go. I can’t see anything exceptional about them.
Thus, the LG L1970HR is a very average monitor in its class. It does not have any exceptional technical properties, except for its low response time, which may only be interesting for people who play dynamic games. The most surprising thing about this monitor is its color temperature setup that yields very cold colors in every mode and calls for a manual adjustment. Well, if you don’t think it a big deal, and you want a super-fast matrix with a reasonable level of RTC errors, with normal brightness and contrast, and at a low price, this monitor may suit you just fine.
