I bet, CRT Monitors do live a long life. Since I had a CRT Monitor for years, I can tell you this with confidence. In terms of hours, CRT Monitors can run for 25000-30000 hours during the entire lifetime. If we do the maths, this equates to 8 hours of running a day for almost a decade. A CRT Monitor could be so good that during its entire lifetime, there are fewer chances that you would have to take it to the nearby repair store.
