The only real disadvantage of LCD projectors is a visual effect that has been known as "Screen Door". This is when you can see noticeable pixels in the projected image...sort of like looking through a screen door.
The effect is caused by the tiny distances between the individual LCD imaging units.
The effect is not as noticeable in models produced recently.

What are the difference between Home theater projectors vs data projectors?
There is very little difference between theater and data projectors. They each use similar technology, each have similar inputs, image processors, lamps and lenses. In fact, many projectors classified as a home theater projector are used for data projection and data projectors are seen doing good service in a home theater. The differences tend be in the way a projector is optimized. Home theater models will be displaying video content rather than computer data. The image processor will be tuned to perform well with moving images rather than static images. Color control is adjusted to offer the best performance for content such as flesh tones, shadows and highlights. A data projector will be less concerned with such details. The way the projector operates may be slightly different. Data projectors often do not have user settings for color tuning, picture-in-picture, gamma controls (a dynamic contrast control). A good theater projector will have a component signal input while a data projector may only have a VGA input. Data projectors are likely to have a DVI input compared to theater projectors which will tend towards HDMI connectors. More important than any of the differences is the image quality. If a data projector delivers a great image from a DVD player, it should be considered along with theater projectors. After all, the sole purpose for a projector is to deliver a good image. It is enlightening to look at some manufacturers' websites. They often show different applications such as home theater, data, portable, education and so on. Many projector models will be found in several categories, demonstrating that even the makers can't precisely classify their own products.

Disadvantages of a paper-based database?
Paper-based databases are prone to errors due to manual data entry and can be easily lost or damaged. They are also difficult to scale and not as efficient as digital databases for searching and sharing information. Additionally, paper-based databases require physical storage space and are not environmentally friendly.
The advantages and disadvantages of primary data?
Advantages and Disadvantages of primary data are: Advantages 1. Data is basic 2. Unbiased information 3. Original data 4. Data from the primary market/ population 5. Data direct from the population. Disadvantages. 1. Large volume of data. 2. Huge volume of population. 3. Time consuming 4. Direct and personal intervention has to be there. 5. Raw data.
Disadvantages of data redundancy?
Data redundancy can lead to storage inefficiency, as the same information is stored multiple times. It can also increase the risk of inconsistencies or errors in the data, as updates may not be made consistently across all duplicates. Additionally, data redundancy can make data management and maintenance more complex and time-consuming.
