As video wall technology has grown in popularity, the displays have begun popping up nearly everywhere. From restaurants and bars to shopping malls, museums and even corporate offices, they seem to be around every corner. However, not all video walls are created equal.
When working with these complex installations, many value-added resellers end up with a less-than-ideal final product, because there are so many small things that can go wrong. However, these four simple tips can help you avoid larger headaches with your next video wall project:
1. Upgrade your source files
A common problem with video walls originates with low-quality source files. You can install the latest and greatest display technology, but if your content is low-resolution, has poor audio or contains choppy video, it’s still going to look and sound terrible.
If a customer is having problems with the quality of the displayed content, start with the source files. Do they match the screens with native resolutions? If not, simply upgrading the customer’s content may correct the problem. If you continue to have issues, ensure that all hardware components match so that your customer doesn’t encounter bandwidth restrictions.
2. Optimize viewing distance versus resolution
In any video wall application, it is vital that the viewer experiences clear imagery and legible text. That’s why it’s so important to consider the viewing distance and resolution.
Of course, the “viewing distance” refers to the distance between the viewer and the display. The smaller the viewing distance, the better the resolution needs to be. That’s because human vision can only do so much to “fix” a low-resolution image—and that effect is magnified the closer the viewer gets to the screen. So, think about the viewing distance for most end users. Will they be five feet away or across the room? The closer they will be, the better the resolution you’ll need. Similarly, the larger the screen, the better the resolution should be, because a bigger screen affects the perceived viewing distance.
Having a firm understanding of how viewing distance and resolution are related gives you newfound design freedom. You can easily adapt the screen to the environment or, if necessary, modify the environment to make the most of an existing screen.
3. Opt for one larger-format display
Instead of using multiple screens to form your video wall, consider opting for a single large-format display. This will allow you to do away with bezels altogether, which will result in a more seamless display. It will also simplify maintenance of the video wall, because your customer will have only one screen, rather than multiple devices and all the associated connections.
As larger-format screens continue to come down in price, this option becomes viable for more of your customers. For those whose budgets can handle a bigger screen, it may be well worth it to spring for a display that will have a greater impact and allow for fewer maintenance costs.
4. Consider serviceability
Video walls are typically used day in and day out, and it’s important that you or your customers can easily access the display for maintenance and troubleshooting. Consider using pull-out mounts that allow simple (and safe) service without disrupting the entire display.
