(4) Luminance, Chromaticity and CCT MeasurementThe LCD module should be stabilized at given temperature for 20 minutes to avoid abrupt temperature changeduring measuring. In order to stabilize the luminance, the measurement should be executed after lightingBacklight for 20 minutes in a windless room.

2.6 Plug and PlayThe new VESA Plug and Play function is used which eliminates the complicated andtime-consuming installation process.You can use the Plug and Play system without encountering usual installation problems.Your computer system can easily identify and automatically adjust the monitor.The LCD Monitor uses Display Data Channel (DDC) to send Extended DisplayIdentification Data (EDID) to the computer system, so the computer system can be setto monitor auto adjust.

2.7 Power SaverPower control system, also called (Power Saver), is installed inside the LCD Monitor.If the monitor has not been used for a certain period of time, the system will turn themonitor to low voltage mode to save power. Slight moving or any click will return to theoriginal image.The VGA card inside the computer handles Power Saver. You can use computersoftware to set the function.The LCD Monitor is compatible with EPA ENERGY STAR and NTEK if used with aVESA DPMS computer.To save power, turn off the power of the LCD monitor when not in use.

A few months ago my brother in The Hague called me up to ask me advice on how to repair his Acer 22 inch PC LCD Monitor with the model of AL2216W. I told him to look inside on the Power and HV board for bulged Electrolytic Capacitors.

After both Capacitors on the Power and HV Board were replaced I tested the Acer LCD Monitor and everything worked splendidly again. Because my brother lives about 172 Km from my hometown Weert, I have to wait until he or one of my other brother or sisters have the time to come to get the like new working Monitor.

The Acer LCD screen comes with speakers for an optimal audio experience. These can be used in a number of ways, from listening to music and videos to combining the speakers with a microphone to chat online with friends and family.Does the Acer monitor come with additional ports or cables?

The Acer LCD 16:10 screen comes with both HDMI and USB ports and cables. These options can be used for a number of different tasks including storing items, uploading documents, installing programs, or making your PC compatible for HD imaging. Other options that come with this computer are VGA ports and cables. VGA is responsible for connecting the monitors to video cards, and it aids in imaging and visual capabilities.What materials are the product made with?

In order to get the best results, it is best to start with a color gamut of 2.2, or better. The final number will be unique to each monitor, so spend a few minutes on this and don"t ty to share color profiles if you have multiple AL2216W"s. If the 2.2 color gamut works, this is often sufficient to clean up poor color reproduction issues for general usage.

I have an external monitor, which is connected to a laptop. I don’t use the laptop’s display, only the external monitor. The monitor is Asus AL2216W (found a manual). It’s connected through VGA. The video card is Mobile Intel 965 Express Chipset.

Colour Depth – For the best colour reproduction you probably need a panel capable of a full 8-bit colour depth, or perhaps a modern 10-bit panel. An 8-bit module offers a true 16.7 million colour palette without the need for FRC technologies used in 6-bit panels. IPS and VA panels typically offer this, whereas TN Film panels do not. Modern 10-bit panels are becoming more widely used, and most use FRC to increase the colour depth from 8-bit (8-bit +FRC) giving rise to a colour depth of 1.07 billion colours. There are very few ‘true’ 10-bit modules available but there are some out there, usually at a very high cost. Some models offer further enhancements such as a extended internal Look Up Tables (LUT’s) where an even wider colour palette is available to choose from. These can help improve gradients and colour rendering capabilities and are often used in higher end professional grade monitors.

Colour Accuracy Potential. It is true that IPS panels are capable typically of very good colour accuracy, but often you will need to carry out proper calibration with a hardware calibration device to get anywhere near this. However, VA and TN Film panels are certainly capable nowadays of reaching excellent colour accuracy if calibrated correctly. If you look through our reviews, you will see some TN Film panels perform very admirably here, despite the assumption that it is an inferior technology by many people. You will also spot that default colour accuracy really does vary from one model to another, and so you may even find some screens with better default colour accuracy with a TN Film panel, than you see at default for an IPS panel (e.g Acer AL2216W vs NEC 20WGX2). All technologies can offer decent colour accuracy once calibrated, it is the other factors discussed above which normally lead people to chooce IPS if they are doing any colour critical work.

Luminance – We aim for a luminance (often referred to as brightness as well) of 120 cd/m2, which is the recommended luminance for LCD displays in normal lighting conditions.

Black Depth – is the monitor luminance or print reflectance for value = pixel level = 0; i.e. it is the deepest black in the monitor. The lower the value recorded, the better. We aim for 0.0 cd/m2 (truly black), but in practice it doesn’t reach this low on modern LCD screens.

Commonly LCD monitors come set with a default 100% brightness which means that luminance is way above the desired 120 cd/m2 we aim for. This is frequently the main issue with LCD monitors, and is something which can be corrected to a comfortable level at least using software methods. Contrast can also be improved to a degree, and colour levels can be evened and at least appear to be at a nice setting. All these methods rely on the human eye, and so the individual preferences and ambient lighting conditions come into consideration here.

There is a very useful website here (http://www.lagom.nl/lcd-test/) which gives you various tests and methods for calibrating your screen. Well worth a look for some free “by eye” calibration.

Proper calibration of a monitor really requires you to use a hardware calibration device. These come in two varieties, with the more mainstream (and affordable) devices being colorimeters. You can also buy higher end spectrophotometers (such as the X-rite i1 Pro) which read the light differently, but the cost is probably prohibitive for most normal users. There are many different devices to choose from which vary greatly in price, performance and accompanying software packages. These devices are connected to your PC typically via USB, and feature a hardware module which you place over the screen. By running the software suite which comes with the device, the tool sits over a background which displays many different colours. These are then recorded by the device and used to establish how accurate the colours shown on the screen are compared with what is being requested by the graphics card. Once this difference is established, the device can be used to correct the difference as best as possible from the screen, and results in a calibrated profile being produced.
