Well, I hated to shatter her dreams, but I explained her that although horses are not that expensive to buy, they are hugely expensive to own. You have the food, the stables, the veterinary costs, the equipment, etc. That’s what every sensible parent would say, right? And my daughter understood – although I can’t say she liked my point of view one bit.
For 24/7 video walls, you also have the initial cost, and the additional expenses.
But if we change the words ‘daughter’ to ‘company’, and ‘horse’ to ‘video wall’ in the story above, a lot of people have difficulties in making the same reasoning. Although the concepts are in fact very similar.
For 24/7 video walls, you also have the initial cost, and the additional expenses. These include maintenance, power costs, repair costs, spare parts, etc. Pretty much like with horses. There is however one big difference: for horses, these ownership costs are pretty much fixed no matter which breed. For video walls, there are huge differences between the different types of technologies, and different brands. So let’s elaborate, and let’s keep on drawing the comparison with horses.
Real estate is expensive. So it’s best to restrict the needed space to a minimum. For ponies this is difficult (and could be filed as animal abuse), but for rear-projection video walls there are possibilities. The shallow depth of Barco’s RGB laser video walls make sure that the needed space is limited. However, there is always the need for a rear maintenance area. But by choosing the front accessible option, the modules can be positioned directly against the wall, eliminating the space needed behind the video wall.
A large video wall, running in 24/7 mode, consumes a lot of energy. A decade ago, when lamps were generally used, this was a really huge amount. The introduction of LED improved energy consumption in a very beneficial way. RGB laser even tops this, being 2X more energy efficient at higher brightness levels. However, there is also the cost of cooling. Because RGB laser produces less heat than LEDs at the same brightness levels, cooling needs reduce. Compared to competing LED-lit video walls, Barco’s RGB laser series let you save 50% on cooling costs.
Lifetime comparison between different types of video wall technologies
Horses get sick from time to time, or need new horseshoes. Video walls can break down, or need preemptive maintenance to keep going. With a guaranteed lifetime of 100,000 hours (or 11.5 years), Barco’s RGB laser banks last longer than any video wall in the industry. Competing laser-phosphor or LED engines have a much lower lifetime – half and two thirds respectively. This means that they typically need to be replaced 1 (for LED) or 2 (laser-phosphor) times during the guaranteed lifetime of Barco’s RGB laser video wall.
Furthermore, Barco’s RGB laser video walls need no color wheel, which also need to be replaced typically twice a lifetime. For a 10 x 3 video wall, this means that 60 color wheels need to be switched, at an estimated cost of 600 USD a piece. Another maintenance cost is calibration and alignment. After time, the colors and brightness of displays change a bit. And though this is not a real issue for stand-alone screens, it’s ergonomically disturbing in video walls. It makes sure that all different tiles look a bit different, giving a horribly unbalanced effect. Manual calibration takes a lot of effort, taking up to one hour per module. That is why Barco has created Sense X, an automatic brightness and color calibration system that continuously adjusts settings for the entire video wall, eliminating manual calibration totally.
There are a lot more cost saving measures in Barco’s RGB laser video walls (we also have the remote power supply, the supreme uptime, the upgrade path, …) but you catch my drift: you best choose the video wall with the lowest cost of ownership. If Barco would create an RGB Laser Pony, my daughter would probably get her way…
