The menu looks plain and is not very user-friendly. It doesn’t remember the last changed option and you have to move through to the appropriate menu item to quit a submenu. On the other hand, the menu offers a rich selection of settings, some other them quite unusual. Particularly, you can set up image saturation and hue and adjust the color temperature from 4000K to 10000K stepping only 500K.
Using the Mode button, you can switch between several presets of image parameters (Custom, sRGB, Text, Picture, and Movie) which differ not only in brightness but also in color temperature.
A curious thing here is that the monitor totally lacks a contrast setting, offering you brightness alone. Instead of contrast, you have three Gain settings, one for each of the basic colors (this monitor doesn’t offer the six coordinates-based adjustment of color reproduction, so the basic colors are the ordinary R, G and B).
By default, the brightness and all the three Gain settings set at 100%. To achieve 100-nit brightness of white, I reduced brightness to 57% and the Gain of each of the three colors to 80%. By the way, when you change the color temperature, the Gain values for the different channels are changed automatically.
Taking a glance at the monitor’s screen I couldn’t find any obvious problems with the image quality. The matrix backlighting is uniform, color gradients are reproduced normally, the viewing angles are wide enough for normal work (the monitor uses a PVA matrix).
The measurements reveal certain defects, however. The monitor’s gamma is initially set too low, resulting in a pale image. The characteristic bend of the curves in the top left part of the graph indicates a problem with reproduction of light tones. The problem is not very serious, though, and most users aren’t even going to notice it. This bend can usually be cured by reducing the contrast and brightness settings, but the curves remained largely as they had been on my doing so in this monitor’s menu.
The color temperature modes are set up with a very high precision. Yes, the temperature is a little too high in the warm modes and a little too low in the cold ones, but there is almost no difference in temperature between different levels of gray which is much more important than an exact coincidence of the real temperature with the name of the mode in the menu. Moreover, there are so many modes available that you can pick one up exactly for your particular conditions.
This monitor is based on a PVA matrix with response time compensation and its speed characteristics are quite typical and familiar to our readers: even with RTC technology transitions from black to dark-gray are slow on PVA and MVA matrixes (here, such transitions can take as long as 75 milliseconds). However, RTC does help to reduce response time on lighter tones, so RTC-enabled monitors on such matrixes are indeed faster than older models. Here, the averaged response of the monitor is 13 milliseconds (a typical RTC-less PVA matrix has an averaged response of about 21 milliseconds) and there are no RTC artifacts at all (to be exact, the RTC error was always so negligibly small that it made no sense to measure it – you can’t spot such a small deviation in practice).
Just as you can expect from a PVA matrix, the monitor’s contrast ratio surpasses any monitor on TN+Film. The maximum brightness is high enough for using the monitor under normal external lighting.
I should confess I can’t make up my mind about this monitor. The FlexScan L778 is a good but somewhat peculiar model. It features an original design, but with a queer stand. It offers rich setup opportunities, but in a not-easy-to-use menu. Talking about image quality alone, the L778 will make a perfect monitor for work and for watching movies, but gamers may find it too slow, even though not as slow as PVA matrixes without RTC are.
