Applications currently on the market up to SVGA (resolution 800x600) and XGA (1024x768), product price 3000-5000 prices higher than SVGA XGA or so. Projector resolution is common there are two ways, one is to TV cable (TV cable) and are expressed in pixels. When expressed to TV cable, meaning their resolution is similar to television, such a major resolution representation is provided in order to match the access projector TV signal. When expressed in pixels is usually represented as a form of 1024x768, in a sense that the resolution is limited to entering the projector's VGA signal frequency and the frequency of certain requirements.
When VGA signal frequency or frequency exceeds this limit, the projector cannot be normal projection display. Projection resolution choices, projection content at the actual decision to purchase any grade of the projector, if it shows the contents of the General teaching and word processing, select SVGA (800x600), demonstrates the fine images (such as graphic design) to choose the XGA (1024x768). Now that mainstream notebook and desktop resolution up to XGA (1024x768) of the standard, recommended in the case of budget allows choose XGA (1024x768) resolution projector.
Maximum resolution is called the highest resolution display, it means the projector can display the full resolution of the input signal. Projectors by image processing algorithms, scaling of the input signal, signal is full screen, if beyond the scope of this projector does not display properly. Early projector line algorithm, namely: linear compression techniques, but this algorithm has dropped the issue. Current vendors products have now been introduced to the new algorithm used to compress signals, namely: intelligent compression, it dropped the issue can be solved.
Recommendation under the same conditions as other performance indicators, giving priority to select compatible high resolution product, so you can accommodate more signal range.
VGA: full name of Video Graphics Array, this screen has basically been eliminated by now, support a maximum resolution of 640x480, but there are still some small portable devices that use this screen.
SVGA: full name of Super Video Graphics Array, a VGA screen alternatives, maximum support 800x600 resolution, screen size is 12.1 inches, this screen because of the lower pixel so the notebook is few.
XGA: full name Extended Graphics Array, is a current notebook commonly used a LCD screen, nearly 80% of the notebooks on the market using the product.
It supports a maximum 1024x768 resolution, screen sizes from 10.4-inch, 12.1 inch, 13.3 inches 14.1 inches, 15.1 inch. SXGA+: full name Super Extended Graphics Array, as an extension of the SXGA SXGA+ is a screen designed specifically for laptops. Display resolution of 1400x1050.
Due to laptop LCD screen horizontal and vertical dot pitch is different from a normal desktop LCD, so the displayed precision higher than the average 17-inch Desktop LCD. UVGA: full name Ultra Video Graphics Array, which on a 15 inch screen laptop screen, support up to 1600x1200 resolution. Due to high demands on manufacturing processes, so the price is expensive.
At present, only a small number of high-end mobile workstation is equipped with this type of screen. Many people want to buy wide-screen home theater projector, the 16:9 ratio is a standard format of HDTV HD signal. At present, the 16:9 there are three primary resolution of the projector on the market: the 854x480 and the 1024x576 and the 1280x720. In the introduction of the new scans show standard, they are called 480p,576p, and 720p.
