The best selling video projectors today are those with high definition modes in the 720p, 1080i and 1080p types. We know of many series from many manufacturers in these classes, such as Mitsubishi HD1000U HD 720P DLP, Optoma HD20 DLP, ViewSonic PJD6531w, Vivitek H1080FD and Epson PowerLite Home Cinema 8100. But what are the differences between these numbers?
The 720p bit is the quantity that refers to the resolution of the image. This means that there are 1,280 and 720 frame sizes in pixels and equates to 921,600 pixels per image. Frame rate (Hz) in 720p is typically 23.976, 24, 25, 29.97, 30, 50, 59.94, 60, and 72. p in 720p refers to progressive scan type. When transmitted at 60 frames per second, 720p presents the highest possible temporal (motion) resolution under ATSC (Committee on Advanced Television Systems) and DVB (Digital Video Broadcast) rules. 720p has a higher vertical resolution than 1080i, which makes it better displayed for sporting events like soccer and car racing.
In this class, we find various types from various brands, such as Epson PowerLite Home Cinema 705 HD 720P, Optoma HD71 DLP, Mitsubishi HD1000U, FAVI RioHD LED 2 Mini Projector, and Panasonic PTAX200U. The price range is from $220 (Mediawise) to $2,700 (NEC NP3250). The average price is around $200-$400.
The term 1080i assumes a widescreen aspect ratio of 16:9, which implies a frame size of 1920 x 1080 pixels. Tea me – meaning intertwined – is a technique to increase the image quality of a video signal without consuming additional bandwidth. This technical video was designed to be shown on older CRT televisions. Typically, the frame rate in this class is 25 (50 fields/s), 29.97 (59.94 fields/s), and 30 (60 fields/s).
1080p video mode is the same as 1080i in pixels, but differs in scan type. The progressive medium, the newest video mode. Frame rates are 23.976, 24, 25, 29.97, 30, 50, 59.94, and 60.
