Couldn't we fit a flatscreen in there? A suggestion heard often when talking about conserving CRT media art. What seems to be an easy solution at first, hides many complications regarding technical, as well as ehtical aspects of restoration.
This video depicts the visual difference of a CRT screen to a LCD. Many impairments can be seen at first glance: Color alterdation, the screen turning dark and mat when viewed from the side.
The lifespan of a LCD and thus sustainability is not in reach of a CRT. Where many CRT screens are in constant operation for decades, the average flatscreen dies after five years. In addition, the picture tube is renewable over and over again.
From a conservators perspective the original condition of an artwork is to be kept. Alterdation has to be prevented by insisting on use of the initial technology. Different temporary video artists showed their fascination for the picture tube even in their artworks.
