When planning an outdoor TV or digital signage display, you have 3 comparisons: standard TV, weatherproof TV, and outdoor TV enclosure. I'll try to give you a quick overview of the possibilities. We encourage you to do your research to make sure you understand the options and make the right choice for your application.

When installing a standard TV, the life of the TV is significantly reduced due to the entry of moisture and particulate matter into the electronics and potential damage to the TV from airborne particles. Some customers are very lucky and their televisions last for several years.
This is one reason why the market is limited to wealthy customers who can afford to swap their external TVs if necessary. Of course, the TV manufacturer's warranty on indoor TVs used outdoors is void. This still happens today.
You have three options for external TV applications and digital signage.
1) As discussed above, buy a cheap indoor TV and hope for the best.
2) Purchase an external value-added TV from a third party.
3) Purchase an outdoor TV cover.
Each solution has advantages and disadvantages. I suggest you do some research to choose the best solution for your application.
The most notable change from what we discussed in option #1 is the huge drop in prices for flat-screen TVs. Anyone who bought it 10 years ago and is looking for a new TV saw this firsthand. Also, the same potential problem still exists. If you choose this option, be prepared for the possibility that one day your TV will never fade again.
The irony, of course, is that this happens in the middle of the game or at the climax of the film, neither of which are pleasant experiences. I can't tell you how many times we've received calls from customers whose TVs have decided to turn off at the worst possible time.
