|
| Squeeze mode | In this mode, |
|
| |
|
|
| recording medium as 4:3 images. |
| ||
|
|
| When these images are played back by the projector in squeeze mode, they are restored to their original 16:9 format. |

|
| sRGB | An international standard for colour intervals that was formulated so that colours which are reproduced by video equipment |
|
| |
|
|
| can be handled easily by computer operating systems (OS) and the Internet. If the connected source has a sRGB mode, set |
| ||
|
|
| both the projector and the connected signal source to sRGB. |

|
| SVGA | A type of video signal with a resolution of 800 (horizontal) ⋅ 600 (vertical) dots which is used by IBM |
|
| |
|
|
| computers. |
| ||
|
| A video signal which has the luminance component and colour component separated in order to provide better image quality. |
|
| ||
|
|
| It refers to images which consist of two independent signals: Y (luminance signal), and C (colour signal). |
| ||
|
| SXGA | A type of video signal with a resolution of 1280 (horizontal) ⋅ 1024 (vertical) dots which is used by IBM |
|
| |
|
|
| computers. |
| ||
|
| Sync (synchronisation) | The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not |
|
| |
|
|
| match this frequency, the resulting images will not be of a good quality. The process of matching the phases of these signals |
| ||
|
|
| (the relative position of the crests and troughs in the signal) is called "synchronisation". If the signals are not synchronized, |
| ||
|
|
| problems such as flickering, blurriness and horizontal interference can occur. |
| ||
|
| Tracking | The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not |
|
| |
|
|
| match this frequency, the resulting images will not be of a good quality. The process of matching the frequency of these |
| ||
|
|
| signals (the number of crests in the signal) is called "tracking". If tracking is not carried out correctly, wide vertical stripes will |
| ||
|
|
| appear in the projected images. |
| ||
|
| USB | An abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which |
|
| |
|
|
| only support relatively low data transmission speeds. |
| ||
|
| VGA | A type of video signal with a resolution of 640 (horizontal) ⋅ 480 (vertical) dots which is used by IBM |
|
| |
|
|
| computers. |
| ||
|
| XGA | A type of video signal with a resolution of 1024 (horizontal) ⋅ 768 (vertical) dots which is used by IBM |
|
| |
|
|
| computers. |
