Resolution dictates the definition and detail of an image and refers to the number of pixels in each dimension, horizontal and vertical,
that a device can display and is simply the physical number of columns and rows of pixels creating the display (e.g. 1024×768). Various resolutions are typically referred to by standards such as VGA, XGA, WXGA etc.
In terms of projector hire or plasma screen hire, what you are looking for when deciding on a projector is the “Native Resolution’. This is the physical number of pixels that the machine actually outputs onto the screen. All of our projector resolutions on the site are shown as native resolutions as opposed to the highest resolution input a display can accept. Many projectors and video displays can process higher resolutions from an input device such as a computer but they cannot output higher than their native resolution.
When hiring a projector or plasma screen, you should take into account what you are going to be showing. For example if you are looking for a projector to hire for a Microsoft PowerPoint presentation where the content is usually big bold text and graphics you probably do not need a particularly high resolution projector. If you are showing photographs that have lots of detail or screening a film, particularly if it is from a HD source such as a Blu-Ray player, then a projector with higher resolution will give you a far more detailed image.
We have a range of projectors with various resolutions. The lowest resolution machine we supply is 1024X768, known as XGA. This has been the most common computer screen resolution for several years and is more than adequate for many users. We do not supply projectors with lower resolutions than this such as SVGA (800X600) which are all but defunct except in budget machines.
We also have SXGA+ (1050X1400) Panasonic and Christie projectors which are an excellent choice for users wishing to show very fine detail in presentaions.
At the top end for projectors are the full HD (1080X1920) and WUXGA (1920×1200) projectors such as the Panasonic PT-DZ110 and DZ-21K and Christie HD18K.
