“Lines of Resolution” is all about the network era—the late 1950s to the 1980s—and how it changed drawing as an art form for better and worse. As more and more Americans brought televisions into their living rooms, the medium, the exhibition suggests, “reached its apex as a tool for cultural control, while also seeding acts of political dissent and artistic experimentation.” Artists took note of television—the shapes and structures it could make, how they moved on screen, the strange way it created color by making phosphor dots glow with electron beams. Think of the German artist Karl Otto Götz’s Density 10: 3: 2: 1., a giant “raster picture” made up of 400,000 hand-drawn pixels, but which resembles the liquid, pre-pixel images made by cathode-ray TVs. The exhibition features over 50 works on paper as well as mixed-media, sculpture, and an immersive installation. —Jimmy Lux Fox
