A inch standard panel, however, has AOC 2239 of the viewing area of a standard inch screen. Bits Per Colour Modern graphics hardware uses 8 bits per colour channel to represent a picture, or 24 bits total 8 bits for each of the red, green and blue channels. This yields around Monitors with 8 bits per colour can reproduce TrueColour images faithfully, but some cheaper models of monitor only have 6 bits per colour 18 bits total, able to reproducecolours. Monitors with 6 bits per pixel have to use tricks such as dithering to trick the viewer into believing they can display more colours than they actually can.

These tricks cannot perfectly replicate the full colour range, however, and can result in aberrations in images being displayed. If AOC 2239 colour reproduction if an important consideration for you, then you should avoid these cheaper 6 bits per colour displays in favour of ones that support 8 bits per colour.

Connections The connection is how the monitor AOC 2239 to the computer. The connection can be either analogue or digital in nature. Digital is considered the preferred connection method today, with analogue being provided mainly for compatibility with older equipment. Analogue connection LCDs are digital devices, meaning that they are intended to work with digital signals. For a LCD monitor to support VGA it must convert the analogue VGA signal to digital, which is certain to result in some loss of image quality, which manifests itself as some apparent blurriness in the image. Analogue connectors are provided mainly for compatibility with legacy hardware, and are becoming less common.

As LCDs are inherently digital, a digital signal will produce the best possible image quality with no distortion or blurriness caused by AOC 2239 unnecessary digital to analogue and back to digital conversion. Contrast Ratio A measure of the difference between the darkest colour a monitor can produce black and the brightest colour it can produce white.

In theory, the contrast ratio should ideally be infinite, but in practice this is impossible because most monitors produce a "black" that is in fact a very dark grey and the white is limited by how bright an image can be without dazzling the viewer. Manufacturers have tended to inflate their contrast ratio statistics, so be wary of manufacturer's claims regarding contrast ratio. Display size Display size is measured in inches, corner to corner across the diagonal, so a 17 inch monitor is 17 inches from its bottom left to its top right corner.

This means that while bot ha standard and a widescreen 17 inch monitor may both have the same diagonal size, the two monitors will have different dimensions. The standard screen monitor will be taller, while the widescreen display will be wider. Dot Pitch Dot pitch also known as line pitch or pixel pitch is a specification for a computer display AOC 2239 describes the distance between dots sub-pixels of the same colour on the inside of a display screen. Dot pitch can be measured in millimetres where a lower figure indicates closer spacingor Dots Per Inch where a higher figure indicates closer spacing. Closer spacing generally produces a sharper image as there are more pixels in a given area.

Luminance Brightness; a measure of how much light a panel can produce. A measurement of to nits is OK for most productivity tasks; nits is better for TV and movies.

TFT Technology Several similar but different display technologies fall under the category of TFT display, each with its own characteristics, advantages and drawbacks. This is because it provides a AOC 2239 compromise between low cost and good response times.

They do tend, however, to suffer from limited viewing angles. As you move away from the centre line of the monitor and start looking at it more side on, the colours become increasingly distorted. They have much wider viewing angles and reproduce colour far more faithfully. This makes them well suited to professional image editing applications, but a poor choice for multimedia or gaming, as the slow response times make ghosting an issue. Modern MVA panels can offer wide viewing AOC 2239 second only to S-IPS technologygood black depth, good color reproduction and depth, and fast response times. The screen itself comes in at Something missing is of course, a DVI connection, and it's not a huge deal with most cards offering HDMI these days, but it's something that you do have to realize as if you don't have a HDMI connection on your card you're going to have to opt for the ugly analogue connector.


With the monitor connected via HDMI and a USB cable connected to enable the touch screen ability, the setup of the monitor is extremely easy. Once in Windows AOC 2239 installed the driver, rebooted and were ready to go with the eFwt. With the monitor up and running I took a second to quickly just look at it and it's really quite a good looking monitor.

AOC 2239 Across the bottom we've got a sound bar and the "Dual Stand" design that AOC has opted for means that the keyboard or even a laptop can sit under the monitor. This is a great AOC 2239, because you would have the monitor closer to you then a normal monitor controlled with your mouse.

Of course, if you need access to the keyboard to type faster you can just pull it out quickly. There's also a fair bit of room under the screen so that if you're using the screen with a laptop you could just move the laptop forward slightly and slide your hands under and type with ease. Of course, it would depend on the thickness of the laptop in hand. Moving on from the aesthetics and onto the actual screen, the eFwt is a nice looking screen. The LED backlit design makes the screen nice and bright, while keeping power draw at a very nice level of around 21w. As we mentioned, the monitor comes with a built-in speaker and if you're using HDMI you shouldn't have an issue getting sounds to the monitor with the same cable doing the video.

Quality isn't that bad. Sure, you're not going to get the house pumping with it, but for a bit of music or just some general YouTube video it does a AOC 2239 job. Until now, though, there hasn't been much outside of pre-built PCs when it comes to getting in on the touch screen action. AOC 2239


Inside the package we've got nothing that you wouldn't really expect with a VGA and HDMI cable, USB cable along with the standard paperwork and driver CD. The monitor is AOC 2239 with a three-pronged grounded plug, a plug with a third (grounding) pin. This plug will fit only into a grounded power outlet as AOC 2239 safety.
