Q. Hi how or what cable would I use to hook up my brand new MacBook Pro 2011 Fall MacBook Pro 2.3GHz to the following Monitor? What ever is easiest and has the best resolution. THANKS!
Samsung 27" LED Monitor S27A550H 1920x1080 VGA HDMI
5000000:1 Contrast|Fast 2ms Response
A. I don't know much about macbooks. but if you have an "HDMI" port on your mac, go buy an HDMI to HDMI cable; (They have all different lengths, depending on how far your laptop will be from the monitor, you choose the length.) they can range from 2 to 25 dollars about, depending on who you buy them from and what length they are. I recommend buying them from places like wal-mart or target, and avoiding places like radioshack. (Also, this is the easiest way, and best resolution, ranging all the way to 1080p. while VGA is low def, and you have to screw it in.)
What are organic Light emitting diodes?
Q.
A. Organic light emitting diodes (OLEDs) are electronic devices made by placing a thin film of an electroluminescent organic material between two conductors of different work functions. When an electrical voltage is applied, electrons and holes are injected into the electroluminescent material. When these recombine, light is emitted. Additional thin film layers are usually added for different purposes such as electron and hole transport. The advantages of organic materials derive from the easiness of chemical manipulation to tune the colours and to obtain low-cost processability such as inkjet printing on plastic substrates. OLEDs can be used for large and small area flat panel flexible self-luminous displays in many consumer products.

===================================
OLEDs are used in television screens, computer monitors, small, portable system screens such as mobile phones and PDAs, watches, advertising, information, and indication. OLEDs are also used in light sources for space illumination and in large-area light-emitting elements. Due to their early stage of development, they typically emit less light per unit area than inorganic solid-state based LED point-light sources.
An OLED display functions without a backlight. Thus, it can display deep black levels and can be thinner and lighter than liquid crystal displays. In low ambient light conditions such as dark rooms, an OLED screen can achieve a higher contrast ratio than an LCD using either cold cathode fluorescent lamps or the more recently developed LED backlight.
There are two main families of OLEDs: those based upon small molecules and those employing polymers. Adding mobile ions to an OLED creates a Light-emitting Electrochemical Cell or LEC, which has a slightly different mode of operation.
OLED displays can use either passive-matrix (PMOLED) or active-matrix addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, and can make higher resolution and larger size displays possible.

Verbatim launches colour tuneable and dimmable OLED lights
13th April 2011
Verbatim's OLEDs can be dimmed, are colour tuneable and are suitable for reading lights . The first commercially viable colour tuneable organic light emitting diodes (OLED) have launched onto the market for use in the general lighting, automotive and airline industries. Verbatim, a data storage and technology developer and subsidiary of Mitsubishi Chemical Group, is behind the new lighting technology. Verbatim claims its VELVE OLEDs emit a soft, glare-free light, which the company suggests are good for reading lights. The lights are also available in different shapes, including squares, rectangles and hexagons.
OLEDs are different from traditional LED lights. OLEDs are solid-state semiconductors that use films of organic molecules thinner than human hair to emit light. LED lights are semiconductors that give off light when a current runs through them. Although energy efficient, they are sometimes criticised for not emitting enough light or for emitting an off-colour light. OLEDs emit brighter light, do not require the use of hazardous chemicals such as mercury, can be dimmed, and they draw less power than standard LEDs.
The VELVE OLEDs have been designed in 14 cm x 14 cm colour and white tone tuneable panels. Users will able to adjust the colours of the lights, giving them the ability to change the lighting to meet the different functions of the space. The company is selling the OLEDs to original equipment manufacturers in the lighting and furniture sectors, but says they are also well suited general lighting application, or for use in vehicles and airplanes.
