OLED is not a very good idea for a computer monitor currently with their pretty bad image retention. Go look at the iPhones at Best Buy. You can see they have pretty bad retention (unless your Best Buy is good and replaces the phones often).
Yea, this is the reason there aren't any OLED PC monitors (unless you count that one portable one that's overpriced and has terrible color reproduction)
I have never seen retention on my Pixel2XL. Not even a little bit. I used to see retention on my last OLED phone. Maybe we're getting close to OLED displays that are good enough? And yes, sometimes I have my phone on for a long time. And yes, there are static elements just like on a desktop.
You wont notice it if you use your phone. Retention happens when the screen is on all day showing a static image that doesn't change. On a macbook that would mean the apple logo for sure would burn in. Hell, even on my non-oled lcd monitors they're burning in even though they're not supposed to.
Even with pixel shifting you can still get retention too, so that's not really an option right now. I'm hopeful some company in the future will come up with a way to prevent it altogether - but it's going to have to be some kind of new screen tech.
I don't leave my screen on the same image all day. It's on about as much as my phone. I turn it off if I'm not actively using it. This is my point. If I can have it on my phone, I should be able to have it on my desktop.
