We are often asked about the difference between Professional and Consumer flat panel displays. The following information is reproduced from the Panasonic Professional website. This article does a great job of explaining why KSi does not recommend consumer displays for commercial AV installations:
Professional vs. Consumer Displays
Despite their similar exterior appearance, consumer televisions — such as those you’d purchase at your local electronics store — aren’t ideal displays for many applications. While they work perfectly at home for watching movies and playing video games, many applications require a display engineered to handle increased usage, expansion needs and varied locations. By adhering to the highest quality control standards for components and manufacturing, professional displays offer significantly better Return on Investment (ROI) than consumer grade displays. Here’s why you should consider a professional display instead of a consumer display:
Hours of operation: Televisions are built to operate for about four to six hours a day. Professional displays, however, are designed to run 24/7, so they’ll last longer and are less likely to fail at inopportune moments.
Tamper resistant control locks: Because flat panel displays are often used in public spaces, such as for digital signage, it’s important to secure them to prevent disruptions to communications and tampering with controls such as power, volume and other controls. Professional displays are designed to prevent such unauthorized adjustments in standalone or non monitored public locations.
Vertical or horizontal mounting capability: Consumer grade televisions aren’t designed to be mounted both vertically and horizontally. When mounted vertically, the television can experience “Gravity Mura,” which can cause dark spots to appear on the screen and reduce lamp life. This discoloration in consumer LCD televisions is caused by pressure in the lower part of the screen, which distorts the alignment of the polarizing film. With a professional LCD display, an improved liquid crystal injection method keeps the pressure at the bottom of the screen at a level that is no higher than that on ordinary TVs or those in a horizontal position. In addition, consumer televisions do not provide airflow for cooling in the vertical position, which can cause the display to overheat and fail earlier than normal. Finally, consumer televisions are usually not designed to be symmetric so they may appear lopsided when mounted in a vertical position.
Warranty: Consumer displays usually come with a one year warranty, which can often be reduced to 90 days or deemed void if the display is used in a commercial application. Professional displays, however, typically come with a standard two year warranty with an option for an additional three year extended warranty available. “Yogore” stains: The liquid crystal and PI film for LCD televisions include a variety of impurities. These
impurities interrupt the reversion of liquid crystal to its original position. This can cause “Yogore” defects, which can cause boundary lines to appear on the screen, diminishing picture quality. There are drastically fewer impurities in the materials used to manufacture professional LCD displays than TV panels, which severely limits the chances of a “Yogore” stain.
Durability: Consumer televisions aren’t built for operating in demanding environments. With professional displays, there are a variety of options to fit any environment. For instance, professional displays often have a fanless design, which is ideal for environments with high air pollutants, such as QuickServe Restaurants (QSRs), which can lead to failure in a display by exposing internal components to elements such as moisture and smoke
genitalsLUTS and ED (39).

. In addition, there are professional LCD displays that are IP66compliant for dustproof and water resistant protection. These are ideal for outdoor use at bus terminals, factories and ski resorts, for example, and are built to function in both cold and hot weather.
Expandability and integration options: Unlike consumer televisions, many professional LCD displays offer Slot2.0 architecture. Slot2.0 accommodates optional boards, expanding the display’s application possibilities. The technology allows you to easily mount applications and allows for a variety of input terminal cards, including the i5/i7 plugin PC capable of running even the most powerful software applications. Professional displays also often offer a flexible design for removing and reinstalling media
PCs without removing the display, simplifying field support, while cutting down on operational expense. Viewing angle: Professional displays are built with an In Plane Switching (IPS) panel, which prevents color change when images are viewed from a wide angle. Some consumer televisions are built with a Vertical Alignment (VA) panel. While both panels have viewing angles of about 178 degrees, the image on the VA panel will be of poorer quality, displaying incorrect colors when viewed from off center angles.
Device control: Professional displays offer increased device control via RS232 or a LAN control. Let’s say a store has a dozen screens. These control options allow all the devices to be controlled from a central location, eliminating the need for a person to run around with a remote control to turn screens on and off or adjust other settings. For larger networks, RS232/LAN Control can be used to monitor hundreds, even thousands, of displays from a central location. Consumer devices lack this capability. Built in rear speakers: These eliminate side protrusions for a clean, modern design with seamless appearance for multidisplay video walls. This will be especially important if the content you’re displaying has an audio component.
Touch screen capabilities: Your average consumer TV is not capable of offering touchscreen functionality. There are professional LCD displays that offer a built in touch screen, creating a perfect tool for way-finding in hospitals or amusement parks, for example. In addition, a touchscreen professional display could be used as an interactive information kiosk or at a QSR drive thru.
