If a monitor works for 10 years that's good mileage though. I once used a Sony Trinitron TV as monitor (and TV) for nearly 20 years. It still worked, but the front panel buttons failed; the entire set of channel/AV switching buttons popped inside the chassis. Plus the PQ was awful by then, the entire color spectrum was strongly migrating towards red... Also, a 14" CRT (which is more like 12" effectively) wasn't so hot in 2005, so I put it out to pasture/of its misery...even gets worse than that sometimes the lines go completely black so you can't see anything, like lterally 1/2 the screen is black.
