Video Wall Reliability

Video wall reliability is one of the most important considerations in control room video wall design. A video wall is a human-machine interface, and we can classify the factors you should consider in designing your control room video wall as either human or machine. Christie control room video wall solutions are designed to address all such factors.

63,000 hours MTBF for Christie 24/7 rear projection products

Christie has confirmed the high reliability of our rear projection products in a RPMX-D120U & RPMSP-D120U Reliability Study. The study found these Christie systems run with an average of 63,000 hours MTBF (Mean Time Between Failure), the longest documented hours of operation in the industry.

Machine factors influencing reliability include:

  • Operating Life
  • Mean Time Between Failure (MTBF)
  • Redundancy
  • Mean Time to Repair (MTTR)

The question your research needs to answer is whether the critical components of the solution will be reliable enough in relation to the criticality of their function within the control room. Your vendor should be able to provide this information.

Christie has the rear screen tiling projection systems to meet your reliability requirements.

Video wall operating life

The video wall's operating life is not simply the length of time it continues to display images. When you budget for the video wall's operating life, you are estimating the period of time over which the solution operates without performance degradation. In other words, how long will the video wall continue to display images in the same manner as it did on the day the solution was implemented?

MTBF – mean time between failures

MTBF is a standard measure of reliability. It indicates the average time between system failures. This measure is not the same as the solution's operating life. In more specific, mathematical terms, MTBF is the sum of the Mean Time To Failure (MTTF – the reciprocal of the failure rate) and the Mean Time To Repair (MTTR).


Is redundancy designed into the system architecture so that one component's function can be taken over by another? In complex systems, this capability is know as failover. Failover capability indicates that the functions of a failed component are automatically (or sometimes just with minimal human intervention) assumed by another component.

MTTR – mean time to repair

Does the architecture permit fast response and failure correction? MTTR is a measure of how long it takes to return a system to full functionality after a failure has occurred. Components of your control room video wall solution should be accessible and easily replaced to achieve a low MTTR value.

The Christie advantage

Christie's wide selection of rear projection systems, display cubes and enclosures, and video wall controller hardware and software are purpose-built to ensure reliability. Christie manufactures all components with proven technologies, and Christie control room solutions are designed specifically for 24/7 control room applications. Built-in redundancy, long operating life, high MTBF and low MTTR ensure the system is there when you need it.
