Digital Signage Technology Tip: Video Wall Bezels
Posted on Tue, December 8, 2009
Advancements in technology over the past 6 months are changing the way LCD video walls are perceived. New ultra-narrow bezels allow for the distance between two displays of only 7.3mm, nearly a 450% improvement from the 33mm spacing for standard commercial grade displays. When viewing at a distance of several feet away the bezel gap between displays is barely noticeable and ensures a uniform picture across the entire video wall.
All LCD displays are not created equal when it comes to stacking them together to create a wall of information. You will pay a premium for the ultra narrow bezels but the effect and atmosphere they create is well worth the investment.
To further maximize your investment in a LCD video wall take a close look at your software to make sure you can properly position content to account for the bezels and enable you to take full advantage of the resolution of the screen.

Digital Signage Technology Tip: Video Wall verses LED Wallboard
Posted on Tue, December 15, 2009
Historically Financial Trading Floors and Business School Finance Labs have used large LED wallboards to post current market data and news. The LED wallboards provide long life, great viewing distances and you could easily build large walls out of them to create a focal point in any trading environment.
A couple of good photo examples can be seen at: PIMCO and University of Pittsburgh.
With advancements in LCD technology and the new ultra thin bezels, video walls have replaced these LED datawalls. For users still investigating the LED wallboard technology here are 5 things to investigate and compare to help make your decision:
Color - with a LED wallboard you get 3 colors (red, green, amber) verses with a video wall you get the full spectrum of color
Flexibility- with a LED wallboard it is alpha numeric meaning a fixed character height for letters and numbers and if you purchase a 16 line by 64 character display, that will always be your limit. The advantage of what you can dynamically do with a video wall is obvious.
Graphics - with a LED wallboard you are limited to alpha numeric characters, with the video wall you can show graphs, charts, animations, video and live TV
Lead time - LED wallboards are custom built to order normally taking 6 weeks or better to build. LCDs are in stock and can ship the same week.
Price - with all of that functionality you would expect the LCD video wall to be more expensive. Actually it is on average 20% to 25% more economical.
Overall LED wallboards are still a great technology, but they just can’t compete with the mass production of LCD screens and in the end price and flexibility will always win. If you want more information you can view a 10 minute video comparison of the technologies.
Digital Signage Technology Tip: Using VGA over CAT5
Posted on Tue, December 22, 2009
Are you concerned with placing media players at the screens for security or service reasons? Are you looking for ways to deploy multiple screens and looking for an economical way to do it?
The solution to both questions is looking to a VGA to CAT5 system. This is NOT using your network or streaming video. This is where you use point to point or a home run cables from a broadcaster located in a secure server room to each display location. By doing this you have moved the media player from behind the screen where it could be challenging to access and service and placed it in the safety and security of your server room. By centrally locating your media player you can now also take advantage of a multi-port broadcaster that will split that signal to multiple screens thus saving you money on software licenses and media players.
