While projection video walls are still available, LCD video displays have become more popular. There are several reasons. One of the advances of conventional displays over projection systems is that the displays produce bright, high-quality, and high-resolution images. Such pictures are definitely worth a thousand words of praise. Yet another benefit of video walls comprised of video displays is that they can be adjusted easily. Thats certainly an advantage for applications such as presentations. Another benefit is that the space between video displays has become virtually negligibletypically about one-fourth of an inch.
Whats the Future?
Although the future of video display-based video walls isnt entirely clear, such systems will certainly become crisper, more versatile, and generally more powerful. From CRT to LCD, and from LED back to LCD, the history of video walls indicates that their future looks bright (and clear).
