A remote control is enclosed with the ProLite C480T. Its ergonomic qualities are not perfect – the device doesn’t lie as smugly in your hand as, for example, the remote controls from Samsung’s monitors. But anyway, it’s easier to use this control than the control buttons on the monitor itself. Of course, the ProLite C480T supports the “picture in picture” mode for working at the computer and watching a TV program “with one eye”.

What about the quality of the image? I want to mention first that the monitor’s matrix is covered with protective glass, and the glares on this glass are rather annoying in a brightly lit room. On the other hand, the matrix is really well-protected here.

The ProLite C480T is based on an MVA matrix and thus has excellent viewing angles and satisfactory color reproduction.

By default, the monitor’s brightness is set to 25 grades (which is the maximum) and contrast to 8 grades (16 is the maximum); it’s hard to tell why the developer implemented such a rough scale instead of the ordinary 0-100 range. By choosing 5-grade brightness and 6-grade contrast I made the screen shine with a luminosity of 100nit. Brightness of this monitor is controlled through modulation of the power of the backlight lamps at 240Hz frequency.

My measurements of the color temperature gave out the following results: the “User” mode by default produces 9080K white and 18,090K gray colors; the “6500K” mode (which is selected initially) – 6160K white and 7800K gray; the “7200K” mode – 6970K and 9240K; the “9300K” mode – 8190K and 12,310K.

The color curves aren’t very accurate. Yes, green is almost perfect, but red is too intensive in the area of light tones, while blue is noticeably above the norm almost along the entire range. That’s why the color temperature of gray is so high (i.e. gray has the characteristic bluish shade perceived as “cold”).

We have a typical response time graph of an MVA matrix here. This matrix is acceptably fast on black-white-black transitions of the color of a pixel, even though it is slower than specified (I want to remind you that the graph shows the pixel rise time, while the full response time is listed in the table below). But the response time grows up quickly up to several tens of milliseconds on black-to-dark-gray transitions. This behavior of the matrix isn’t critical for watching films, but the “ghosting” effect around moving objects may become unpleasantly strong in games. This is a subjective thing, though. You just make sure this ghosting doesn’t annoy you before the purchase of the monitor.

The contrast ratio is very good, but the brightness couldn’t make it to the declared 430nit. On the other hand, such a high brightness is hardy ever necessary in practice, as those effective 300 with something candelas per sq. meter should suffice even for playing games and watching movies at normal daylight.

Thus, the Iiyama C480T is a cute cross-breed of TV-set and monitor, although some users may be taken aback at its high price. You can have a 19” monitor and a TV-tuner for less money, if you purchase them separately. Besides that, the C480T isn’t free from such drawbacks as unhandy controls, inaccurate color rendition setup and high response time (this defect is peculiar to all MVA matrices, though), which are the harder to put up with because of the same high price.

Anyway, this monitor will suit well for watching movies and TV programs. If you’re planning to buy it for playing games, but have never before met an MVA or a PVA matrix with their characteristic response time, you’re taking some risks. This model is not the best possible choice for work unless you’re accustomed to work in a well-lit room: the brightness of the screen may be excessive under mild indoor lighting.
