The Things Customers Expect from a Modern LCD Monitor
In these days of SDI, HDSDI, 3G, HDMI and whatnot, the volume of video sources and devices that want monitoring is constantly diversifying. Regardless that there have been some distressing signs in connection with future of the 3D market, there is still presently a large level of 3D acquisition and content, that will require its own finely detailed monitoring. And it’s not all about the most recent, technology . The enormous volume of analogue products still used means there exists still a vital requirement for composite and component monitoring. This means added costs for studios and broadcasters, but is felt particularly acutely by rental firms. With such a mixture of possible demands, it can be difficult for rental establishments to decide what type and quantity of monitoring equipment to purchase.
Rental companies also have to be aware of the increasing number of applications and features clients expect LCD monitoring equipment to have. Audio level metering is one common feature of modern LCD monitors. A modern monitor therefore needs to be capable of de-embedding and displaying up to 16 channels of audio - with each channel having its own Audio Meter with user-adjustable reference levels.
Today, LCD monitors ought to be typically capable of monitoring waveforms in a number of aspect ratios, positions and transparency options. Built-in Waveform Monitors do not simply offer users the capability to keep an eye on luminance. Clients can steer clear of out-of-range conditions (e.g. overexposure or “blacker-than-black” errors) by applying adjustable warning limits.
User-adjustable Clip Guide functions are available on plenty of modern LCD monitors, enabling over-and-under exposures to be precisely displayed during diverse shooting conditions. Any exposures over or any blacks under certain user-defined levels will automatically change colour (e.g. to red) on the Waveform and picture as selected.
Software algorithms correct non-linear curves, emulating the gamma characteristics of a CRT monitor on an LCD monitor . The three non-linear colours have to be corrected at the same time, making the process complex, but gamma correction ensures panels and channels are correctly matched.
One potential problem with LCD monitoring equipment is the fact that changing the luminance level can affect the white balance. This tends to bring about colour-matching complications, as greyscale should maintain the exact same colour temperature in order to display colours correctly. In an effort to remedy this problem, some LCD monitors now feature a “one button” solution, which uses an industry standard colour analyser in order to make calibration simple.
