What You Need from a Modern LCD Monitor
In these days of SDI, HDSDI, 3G, HDMI and whatnot, the numerous video sources and devices that necessitate monitoring is always diversifying. Though there have been various disturbing alerts concerning the long term viability of the 3D market, there’s still presently an expanding level of 3D acquisition and content, which will need to have its own comprehensive monitoring. And it’s not just about the current, digital technology either. The great quantity of analogue devices still getting used means there is still a substantial requirement for composite and component monitoring. This means added costs for studios and broadcasters, but is felt particularly acutely by rental businesses. With such a variety of needs, it can be difficult for rental businesses to figure out what kind and quantity of monitoring equipment to stock.
Users’ demands of their LCD monitors have also increased in line with the growing plethora of equipment on offer, meaning rental companies have to balance both stock and the abilities of those individual products. 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.
These days, LCD monitors ought to be capable of monitoring waveforms in different aspect ratios, positions and transparency options. Built-in Waveform Monitors do not merely offer users the capability to monitor luminance. People can keep clear of out-of-range conditions (e.g. overexposure or “blacker-than-black” errors) by using adjustable warning limits.
User-adjustable Clip Guide functions are found on various modern LCD monitors, enabling over-and-under exposures to be precisely displayed during different conditions. Any exposures over or any blacks under certain user-defined levels will automatically change colour on the Waveform and picture as selected.
In order to emulate CRT monitor gamma characteristics, corrective software algorithms are used on non-linear curves. The three non-linear colours have to be corrected at the same time, making the process complex, but the manufacturer’s gamma correction ensures panels and channels are correctly matched.
One potential drawback of LCD monitoring equipment is the fact a change in the luminance level can impact the white balance. This tends to bring about colour-matching problems, as greyscale has to maintain the same colour temperature in order to display colours accurately. In an effort to remedy this issue, some LCD monitors now have a “one button” solution, which uses an industry standard colour analyser in order to make calibration simple.
