Hardware

It's a very realistic test for monitor usage, especially when you are buying for longevity. My taskbar gets 5000 hours/year of display time on my main monitor and closer to 7000 hours/year on my secondary monitors.

My oldest monitor is at 9 years old now running 20 hours per day continously and it has no loss in quality or performance at all - and I expect to keep it for at least another 4-5 years.
