Cost of Ownership

Each control room display wall solution is unique and when calculating the total cost of ownership take your unique needs into consideration.

When determining requirements for constructing, operating and maintaining a control room there are many elements to be considered. The key elements that impact the long term Total Cost of Ownership (TCO) are:

  • Initial product purchase including electronics and display structure
  • Consumables, specifically projector lamps
  • Service components and repairs
  • Ongoing maintenance costs for the electronics
  • Power consumption for 24/7 operation of the electronics and cooling requirements
    installation of the electronic system

The wall design is a critical consideration in a product purchase. Christie recommends that you work with a trained and qualified partner, with advanced audiovisual technology experience. Ensure they have first-hand experience with all the product choices available. They will be able to provide the guidance that will save you costs in the long run.

Configuring a display wall

The basis for determining the configuration of your required display wall includes:

  • The available space for wall including the electronics required for the wall and operator work space within the control room,
  • The number of operators and their distance from the projected image,
  • The amount of content required in the display,
  • The level of detail required for the displayed image.

Each wall will be unique based on the individual needs of the user.

Consumable components of a display wall

Consumable products are classified as a component of the wall that will require a regular replacement. The lamp of a projector, much like a light bulb, will over time burn out. The cost of replacing the lamps varies depending on the type of lamp. A mercury UHP lamp will last longer than a Xenon lamp and the replacement cost is also reduced.  An LED illumination system of Christie Entero™ products will last almost 7 years, with 60,000 hours rated life on illumination.

The life span on the lamps can vary based upon usage. If the projectors are set to Maximum Image Brightness their lifetime is reduced versus Economy Image Brightness, which could extend the lifespan by 1,500 hours for a Xenon lamp and possibly 4,000 hours for a UHP lamp. 

Service requirements of a display wall

As there are bulbs that will require replacement there will be a need for servicing the projectors. Once a lamp fails it can easily be replaced within a few minutes while the projector is still operational. All Christie projectors auto-calibrate. Upon a lamp change the auto-calibrate feature automatically adjusts display color settings to compensate for lamp color variation between old and new lamps.

Christie recommends establishing a service agreement with the company that is installing your display wall. Their trained technicians will have experience with a variety of projection products and will be able to quickly assess any service issue and be able to quickly get your wall up and running. Christie offers our partners comprehensive three-day technical training specific to Control Rooms, installation of the cube structures and mounting of projectors, ongoing maintenance and programming of our TVC Controller series.

Ongoing maintenance through ongoing monitoring

Our ChristieNET™ Master Display Controller software removes the guesswork from maintenance. This internally driven browser-based software provides extensive control and monitoring of Christie projectors with a simple and easy-to-use software interface. Simply connect the projector to your network using the projector’s Ethernet RJ45 connector and ChristieNET™ is available using your standard web browser. ChristieNET’s extensive features allow numerous diagnostic and control benefits, including event scheduling, real-time clock, and real-time diagnostic reporting via email.

Technology choices can offer more cost saving options

Pixel Count or Pixel Pitch are terms used for configuring the resolution requirements of a display. If the operator is sitting 10 feet from the screen a good rule of thumb is 20 – 25 pixels per inch of screen. If they are further than 10 feet from the screen, they will not require the same level of detail in the screen resolution.

The high levels of brightness and comparable resolution through fewer projectors are the technology advancements a 3​DLP® projector is able to offer. Reduction in the number of projectors needed within the wall configuration reduces a number of requirements:

  • Individual electronic components to be serviced and maintained
  • The cube structure is reduced for quicker installation and calibration
  • Reduction in energy for running and cooling projectors 

Reduction in the number of projectors and components of the overall wall structure can be a major benefit in the life span of the system.

24/7 operation needs special consideration

DLP® projection technology is ideal for running 24/7. Christie projectors have been built to the highest-performing standards of reliability and Mean Time Between Failures (MTBF) calculations demanded by our users including military installations and 24/7 Mission Critical Environments.

When configuring a system, with all of its unique requirements, Christie recommends you work with an experienced AV partner. We would be happy to help you in finding the right partner for your specific project. Together we can work through all the elements of a TCO calculation specific to your project to prepare for ongoing requirements of the wall and ensure ongoing success in the 24/7 operation of your control room system.
