Ghosting is typically used to describe different things. If you start to see the word safari, finder, etc still showing up faintly on your display, that is called image persistence. If you're looking for real information such as white papers, warranty details, etc. I encourage the use of the term as it's more likely to turn up real information. It also showed up long before LED backlit displays. This goes all the way back to early plasmas and many displays with ccfl backlighting. It used to be much more common than it is today.Bull. It's called ghosting, not persistence, and (someone correct me if I'm wrong, but) the only macs that exhibit this behavior use LEDs for a backlight, so the useful length of the backlight should be forever.
I used to have it on my 23" pre-LED Cinema Display, so it's not just LED products. The dock was the main problem usually since it sits there all the time. It got kinda bad after a year or so, where even switching the display off overnight wouldn't completely remove it, but I kinda got used to it and just lived with it.the only macs that exhibit this behavior use LEDs for a backlight
Sleazy. Sorry, there is no other word for it.
They're wider, with more grilles/vents (and at the top with no shroud). They get warm, but not enough to adversely affect the display within such an embarrassingly short period of time.Glad my TV doesn't do that.
I forgot about that; the Retina issue being a different situation... the article I read from someone else posting the link is about iMacs... IPS screens tend to be slower with response time in general. Such ghosting would not surprise me, at least for motion video. Burned in/totally retained imagery is my worry. If the pattern clears within a few seconds, but such high densities of transistors could be an issue long-term... Newer generations of Retina will doubtlessly improve...My rMBP with the LG panel indeed suffers from image retention. But: the only way to actually notice it is to have a checkerboard pattern on the screen for around 20 minutes and after that switch to a dark background. I have been working with this machine for quite some time now and so far, could't find a situation when it was actually an issue (or even detectible) during my normal usage (both in work and gaming) - and I usually have static UIs, like TextMate, open for a long time. If all the other machines are like that, then I honestly don't know what people are complaining about.
