Is having a slide show screen saver on 24/7 bad?

I had to RMA my monitor because the color went bad on the right side of the screen. Like red became pink on the right side of the monitor. I bought it 8 months ago. Was having a slide show playing 24/7 cause my screen to go bad so quickly, or was it I just got a bad screen? The brand was Samsung, the monitor was 600 dollars.

I know having a slide show playing 24/7 shortens its life. But 8 months? I'm thinking at least 4 or 5 years?

There is no definitive answer to this. Mean time to failure is just that - an average. If you took 1000 screens & ran them all 24/7 some would die in a week, some would be fine after 10 years, the rest would form a bell-curve somewhere between.

I used to install & maintain such screens for use in in-store advertising, so they'd probably be running 16 hours a day not 24 - but the same pattern emerges. Some die in a week, some go on forever.

So long as you don't get static image burn-in, which you shouldn't on a slide show, then just run it til it dies.

Screens that only get used an hour a day will die eventually too - not necessarily lasting longer than those on constantly. I had a Mac Pro running as a 24/7 server that lasted over a decade. Never slept, never shut down or rebooted except for system updates.

This, btw, is why we have legally-enforced warranty periods [different per territory, but similar in essence]. So long as you use a product 'reasonably' - which precludes using it for football or as a beer receptacle - then if you get one of those that dies early, the law deems it a manufacturing issue & you get a shiny new one.
