About LCD and CRT Monitors - part 2

- Additional factors in selecting your computer monitor technology

Less obvious but important distinctions between LCD flat screen monitors and CRT monitors:

• Health. The flicker experienced on CRT screens which result from their need to be "redrawn" frequently (known as the "refresh rate") can lead to eye strain and headaches. LCDs, on the other hand, are basically flicker free. In addition, CRTs give off radiation in the form of ELF and VLF, resulting in health concerns for users and controversy in the industry.

• Computer monitor energy and heat. LCDs are more energy efficient than CRTs and can result in slight monetary energy savings over the course of a year. There is less heat generated by LCDs so users experience less heat discomfort.

• Cost of ownership: While acquisition costs are still higher for LCD displays (though the price has been coming down), other costs may be  minimal compared to CRTs. As examples: LCD backlights last 2x as long as CRTs and cost less to replace, and are able to be replaced in the field without test equipment; while CRTs must be sent to the factory for testing and replacement. The weight of CRTs increase their shipping costs.

• Viewing angles. CRT monitor screens allow viewing access from all angles - a definite plus when you have people crowding around your desk to view something (Though a definite security risk recognized by HIPAA regulations. Using  privacy filters helps provide HIPAA compliance). LCD flat screen monitors, on the other hand, have a limited viewing area, so this screen appears slightly washed out when viewed from "off-center;" this can be problematic in group consultation situations.

Office ergonomics addresses the comfort, safety, and organization of your work area and business tools.

With desks no longer dominated by large CRT monitors, your work area is less crowded and you gain additional work surface. Light-weight, LCD flat screen monitors can usually be easily moved without straining.  Or, you have an option of attaching them to LCD monitor arms.  These ergonomic accessories provide easy positioning adjustment and elevate them above the desk. Swing them out of the way when they're not in use.
