Commercial V Domestic LCD Displays

At Intevi we always recommend then use of commercial grade displays for professional installations.... Although there is a price increase we believe the following reasons will justify the small addition, over time the original increased cost will actually save you, the client. By having better heat and power specifications and sometimes 3times the warranty length the total cost of ownership is better when using commercial displays .

Do you need to pay for the difference?
When it comes to choosing an LCD or LED display/panel for your premises, there are clearly two options, being a commercial grade panel or Domestic/Consumer version. To look at, they may seem the same, however like all things, there are several important differences to consider before you charge off to your local retailer.

The differences between the two types of displays are summarised below.
Image compatibility & resolutions
Mounting options & orientations
Suitability of environment
Operating hours & heat management
Audio & video inputs
Integration with a larger system or control via a third party control system.
Interconnectivity to/from "video walls"
Boot up/power up modes
Brightness levels
Length of Warranty
Power Saving

Image compatibility & resolutions
Commercial
Designed specifically for compatibility with PCs and AV standards.
Most models recognise all PC resolutions in addition to TV/video resolutions.
Domestic
Most are designed specifically for TV/video formats with very limited PC resolutions.

Mounting options & orientation
Commercial
Most support VESA mounting configurations and can be oriented in a variety of angles including: horizontal, vertical and in some cases angles in between.
Domestic
Newer screens support VESA mounting configurations due to the popularity of wall mounting screens, however not all do and in some cases additional hardware required for Portrait orientation mounting is typically not available with domestic/consumer grade models.

Suitability of environment
Commercial
Includes ways to protect controls in a public environment including the ability to lock the use of buttons on the actual panel or use of the manufacturer remote control.
Domestic
No ability to lock display control

Operating hours & heat management
Commercial
Commercial grade flat screens are built with heavy-duty parts and components designed to handle the wear and tear. Along with an increased resistance to deterioration, these high-quality parts also extend the lifespan of commercial screens far beyond that of consumer models, something that is critically important when one considers the difference in operating hours between the two.
Commercial screen models are now being designed specifically for extended-use applications and some also include features such as enhanced burn-in protection and cooling mechanisms.
Domestic
Consumer screens in people's homes are turned on anywhere from one to eight hours a day, and serious TV watchers or gamers may even have them on for 12 or more. But, many deployers demand 12-15 hour days out of their screens and locations like airports may never turn the screens off. Designed to be run as a TV installed into a home would be, approximately 8-12 hours of daily use would be the maximum recommended amount, we also think that

Audio & video inputs
Commercial
Most models Include:
Control - IR & RS232 for control by a 3rd party control system
Video - PC, RGBHV on BNC connectors, Composite, S-Video, Component, DVI-D, HDMI, Display Port
Audio - Option to include or remove speakers
Domestic
-Most models offer:
Control - Infra-Red (IR) control only
Video - PC (becoming more rare), Component, Composite, HDMI
Audio - Inbuilt speakers on RCA connectors

Integration with a larger system or control via a third party control system
Commercial
- The majority (if not all) provide bi-directional serial control allowing a third party processor to control the screen. One of the main advantages of using a commercial grade screen with a third party control system is the ability to switch directly to an input source on command or when an input is sensed.
Domestic
- While domestic LCD screens can be used to integrate with larger systems it is much more 'clunky'. this is down to the fact that most of the time inputs can only be selected by via scrolling through all the inputs until the appropriate one is available.

Interconnectivity to form "video walls"
Commercial
Not all commercial screens support interconnecivity but generally the top models support this ie NEC's tilematrix mode. This special mode allows many screens to be connected together through their cabling systems and be treated as one big screen.
Domestic
Consumer screens just don't support it natively. If you want multiple screens to be treated as one big screen, you are going to have to supply Computers that have multiple video ports and connect them virtually through the software drivers.

Boot up / power on mode
Commercial
Can be configured, but generally the default mode is to start automatically. ie... if the power goes off, you can expect these panels to start back up and display your content without human interaction.
Domestic
Are generally the opposite, any power loss generally means any restart is in 'standby mode' and someone will need to push the on button.

Brightness
Commercial
Have models that they call in the trade as 'high brights', which are generally models that are 700lumens / Nits, and are required for locations that face outdoors ie shop windows
Domestic
Are usually around the 350 to 500 lumen level.

Length of Warranty
Commercial
Since manufacturers build commercial grade screens to last, they also stand behind the production quality of those screens. Many of the top-grade manufacturers will do so by offering a more robust, multi-year warranty program for their lines of commercial grade screens than they do for consumer grade models.
Domestic
While Consumer products may have upto 3 years warranty, they usually specify within the documentation that use over and beyond four to six hours a day will void the warranty. Moreover, the commercial usage of consumer grade screens usually reverts the warranty to 90 days.

Power Saving
Commercial
These are generally becoming standard on commercial panels. Large LCD panels can draw a lot of energy, especially when run 24/7. These features may include:
Intelligent Sensor: Responds to the ambient light in the room and then reduces brightness and energy output under most circumstances.

Dynamic Power Savings: Responds to the brightness level on the incoming video while still providing superior picture quality to guests.

Static Power Savings: Allows the installer to set the preferred power consumption level.

Domestic

No manufacturer for domestic screens offer these features, however they do offer some very basic power saving features.

While this is a good list and should help you justify the right investment, it's not the definitive list, and there are other reasons, but it should give you an idea on why Commercial Panels are more expensive and why they exist in the market.
