The short answer is yes but they have to be protected from harsh outdoor elements. If the indoor TV is kept in an outdoor cabinet or hung in an outdoor area with a roof like a covered patio, then it will be protected from water which is the biggest threat to an indoor TV. With that being said, outdoor TVs are much more versatile and can be hung anywhere while withstanding the elements. The other factor to keep in mind is that outdoor TVs are built to be easier to view under extreme sunlight conditions as opposed to their indoor counterparts. With outdoor TVs coming down drastically in price in the last few years, consider where you are installing it and weigh the investment vs. the function to decide on the best option. Photo Source ***
