The number of video sources and devices is increasing more rapidly than ever. Modern LCD monitors need to have devices to monitor audio, limit over exposure and manage colour palettes. Rental companies should be aware of the different capabilities modern LCD monitors are expected to have.

In these days of SDI, HDSDI, 3G, HDMI and whatnot, the number of video sources and devices that need monitoring is continually diversifying. Regardless that there have been plenty of concerning alerts in connection with future of the 3D market, there is still currently an expanding level of 3D acquisition and content, which will have to have its own in-depth monitoring. And it’s not all about the hottest, technology . The enormous volume of analogue equipment still used means there exists still a substantial requirement for composite and component monitoring. This all means extra expenditure for studios and broadcasters, but is felt particularly acutely by rental businesses. With such a variety of potential expectations, it can be hard for rental firms to decide what kind and quantity of monitoring equipment to buy.
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. Many clients now expect audio level metering to be possible through their 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 commonly capable of monitoring waveforms in a number of aspect ratios, positions and transparency options. Built-in Waveform Monitors don't simply offer clients the capability to keep an eye on luminance. Users can keep away from out-of-range conditions (e.g. overexposure or “blacker-than-black” errors) using adjustable warning limits.
User-adjustable Clip Guide functions can be available on lots of LCD monitors, allowing over-and-under exposures to be displayed during different 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.
In order to emulate LCD monitors 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 in built gamma correction correctly match panels and channels.
One potential disadvantage of LCD monitoring equipment is the fact that a change in the luminance level can impact the white balance. This will cause colour-matching difficulties, as greyscale has got to maintain the same colour temperature in order to display colours correctly. In order to solve this problem, some LCD monitors now come with a “one button” solution, which uses an industry standard colour analyser in order to make calibration simple.
