HD projectors

In the past, it has always been true that the general picture quality of fixed-screen devices has been a few steps ahead of projection devices - however, both viewing methods have since improved at a similar pace. When TVs and monitors were developed with the capability to display content at a HD resolution, it was only a matter of time before projectors followed suit, and these high-definition devices have become popular in both home cinema and office environments. As demand has increased for larger and larger images, the resolution has been forced to improve in line with market trends to ensure that there is very little in the way of loss of detail.

In order for a projector to be classed as ‘HD’ or ‘HD Ready,’ there are a number of criteria that need to be met. First of all, the device needs to be capable of displaying content in a widescreen aspect ratio - the most popular form of this is 16:9. HD content that is produced in this format will have an overall resolution of at least 720p, and this indicates that there are a minimum of 720 horizontal lines of detail that make up the screen area. A 720p resolution may also be described as ‘1280 x 720,’ and a PC-based WXGA layout would be referred to as ‘1280 x 800.’ Although Blu-Ray players are usually capable of outputting video at a quality that is higher than 720p, digital TV broadcasts are usually around this standard.

When there is a ‘HD Ready’ logo on a projector, this is an indication that there will be some kind of cable input that is capable of carrying this high-quality video signal. HDMI (High-Definition Multimedia Interface) is a universal cabling system that has been developed to provide a common means of connecting a wide range of high-definition devices, and it is convenient for projector owners - HDMI cable lengths are available to suit a variety of different setups, and there is usually no noticeable loss in terms of signal quality. An initial glance through an AV cable store demonstrates that there are many different varieties of HDMI cables on offer, but the digital nature of the signal means that many regular users won’t have the need to purchase top-end cabling. HDMI is also capable of carrying audio and network data information, making it a smart choice for setups with numerous connected devices.

One of the most common complaints relating to HD projectors actually comes down to a level of understanding regarding the technology. HD projectors and TVs are incapable of displaying a HD-quality picture when they are connected using an older cable format, such as SCART or RGB - this means that complaints about picture quality can often be resolved with the purchase of a simple HDMI cable. In the event that there is no HD video source, these modern projectors are also capable of ‘upscaling’ standard definition content, and there is still a significant improvement in the viewed image.

In summary, HD and HD-ready projectors can display a video signal in a resolution higher than 640x460 pixels. These projectors are ideal for movies, digital television, video games, and even in a business setting.
