REVIEW: LG Flatron M2794D Part 14
LG has mentioned a response time of 5 ms for the TN panel used in the model. No details are provided on the measurement methods used. However, this is probably a grey-to-grey change.

An overdrive solution should improve the response time but in this case, it only produces unpleasant artefacts. Clear corona effects (also called inverse ghosting ), a bright halo around dark edges, are omnipresent and spoil games enjoyment enormously. "RTC" should therefore always be left deactivated. This means that although the panel in the LG M2794D is not in the top league with regard to its responsiveness, a clearly more harmonic image is presented to the user.

The subjective display quality in games is patch. The mediocre FRC implementation can stand out unpleasantly in dark games. Dithering patters can be seen sporadically, depending on the image content. On the other hand, the good illumination, together with the balanced image homogeneity, the low black level and the high contrast, has a positive effect on gaming enjoyment.

Like all Hold-Type models with a static backlight, the LG M2794D also demonstrates slight motion blurring, but this can be considered non-critical.
As well as the response time, the oft-mentioned input lag is also relevant with regard to a monitor’s suitability for games. If too much time passes between input and optical feedback, the controls become too indirect for the fraction of "hardcore gamers" in particular.
In our stopwatch test against a CRT model, the LG M2794D does not achieve pole position, but is still far from being unsuitable for gaming. On average, we measured a value of 30 ms. At a refresh rate of 60Hz, there is an equivalent lag of two frames (2 fps). Individual peaks reach 45 ms, whilst the minimum value measured was 10 ms.
For very ambitious gamers, the lag could be annoying, but most users should not find it a problem.
