Physicians and air traffic controllers have at least two things in common:
They control the fate of many lives, and they need extremely high-resolution computer graphics to make decisions that affect other people.
Orlando-based Tech-Source Inc. can fill that need - the company has created technology that gives "the highest quality image anyone has ever seen," says Michael Tobias, president of the 8-year-old company, which builds graphics boards for computers.
Traditional computers have a resolution of 640 by 480 total dots. Tech-Source can give 2,560 by 2,048 total resolution - twice as much as the highest resolution available on the market today.
"We provide more dots per inch," says Tobias, 33, who has two bachelor's degrees from Western Michigan University - one in computer science and the other in math. "That means higher resolution, which gives finer detail. We are at the peak of technology."
That technology is important to air traffic controllers, who use larger monitors than most people. The bigger computer screens allow the controllers to look at more air space at the same time.
Simply enlarging the computer image would make it grainy.
However, the greater resolution provided by Tech-Source's graphics hoards means they …
