An expert LCD multimedia projector is a great asset for any person or company. But, you need to know important things before purchasing one. Most of LCD multimedia projectors require considerable financial investment, therefore you should try to make a knowledgeable decision. There are different models and makes around now, you actually need to do detailed homework when you want to purchase a good LCD multimedia projector. Here are main factors to keep in mind before purchasing:
Of all the things and aspects that should be taken into contemplation, this is perhaps the most essential, as all other aspects would depend on it. Do you want to use your LCD projector in regions where there is increased amount of ambient light? Do you intend to execute different presentations or mostly show movies? Will you utilize a single personal computer or do you want to connect numerous video sources? Will you keep moving the LCD projector or it will be permanently installed at one position? Do you have a limited budget or an extensive budget with respect to LCD multimedia projectors?
This is perhaps the second most vital factor to keep in mind. You must try to make it sure that your LCD projector has adequate light output in order to be clearly visible to viewers or spectators. If you want to use your unit in regions where there is increased background light, then this point should be given due consideration. No one will take pleasure in a presentation they find it hard to see. The concept of brightness is actually measured in Lumens. Brightness yield of 1000-2000 is generally fine for a small office or classroom and a yield of 2000 Lumens is adequate for bigger conference rooms or classrooms. You should not consider anything that imparts fewer than 1000 Lumens. On the other hand, contrast is always measured as the proportion between the darkest parts and lightest parts of the exhibit. You should not consider LCD multimedia projectors with a contrast proportion of below 400:1, particularly if you want to operate in a region with background light. Moreover, low contrasts provide a "washed out" display.
Diverse models actually come with distinct resolution capabilities. It must be noted that, higher the resolution more costly the unit. General resolution is actually measured in pixels. The most regular resolutions are 1024x768 (XGA), 800x600 (SVGA), 1280x1024 and 1600x1200. The overall resolution of LCD multimedia projectors will generally conclude how much a person can "fit" easily on the screen. If you want to compare the resolution you can easily use your personal computer or laptop. If the screen resolution is 1024x768 (common in use these days), then you will get a detailed idea of how large things are related to full screen resolution or size. It has been observed that XGA resolution is good for business presentations, numerical data, etc. and today you must possibly be looking at this specific resolution in order to obtain top quality audio and video.
