I have a friend who needs to show her digital artwork in a gallery. As she consulted me about it, I realized that it is an interesting problem.
Now LCD monitors are quickly becoming the norm. They are no longer a novelty item that connotes future. I feel like this shift in public perception has happened just this year. The problem for cost-conscious artists is that they can no longer use CRT monitors to present their work in a gallery because they now have the connotation of being retro, or just-past. Unless your work is about being retro or just-past, they are inappropriate.
But on the other hand, LCD monitors are still quite expensive, especially large ones. On top of it, they do not withstand well the abuse of the public users who tend to poke their fingers at it. Most gallery shows last about a month. You cannot afford to sacrifice your own monitor for a month, unless you happen to be going on vacation at the same time your have a show. Unless you are Cory Archangel, you do not have shows every month to make it worthwhile to buy one specifically for exhibition purposes. Renting it for a month is quite expensive too.
So what do most artists do in this situation?
