Just wanted to add that my iMac 27" (late 2009) has recently started to exhibit the black blotches syndrome. Worth adding that it comes from a centrally heated, smoke free, candle free house with no real huge variations between hot and cold and no humidity issues. Also, when I do anything that may cause the GPU or CPU to heat up a little I use SMC Fan Control so the internal temperatures never get ridiculously hot.
Same thing: in our office we've got Apple Cinema LED display, which due to the tasks has to run 24/7 turned on, Mac Pro has SmcFanControl installed for this display. And display had still developed these black spots! So as several other iMacs. But not all of them, some iMacs run about a year, they get heated pretty well, but are still alive....the problem is related to condensation on the panel which develops when you power down the system. Basically ...the computer needs to keep warm i.e. stay on all the time. Set the energy preferences to never let the system sleep and put the screen saver on. You can set the display to sleep but not the system. FYI, I have a dual monitor imac setup and my other monitor is the dell U2711 which uses the same panel as the 27 imac. I've NEVER had a problem with it - it's an amazing monitor.
I'm on my second black-spot screen, getting my 3rd panel this week.
My imac 27" is running pretty much 24/7 and the black spots began to appear a few weeks ago.
,Just wondering if everybody here who's had this problem happened to be using Boot Camp as well, or some other software that might cause extreme heat.
-May I ask, do you often run Windows using Boot Camp?
That's true. Our office has maaany computers and monitors, and we only had such problems with Apple monitors and iMacs. The Apple Cinema LED display had the same black spots problem as iMacs do. And that computer had never been used with BootCamp....the problem is not due to gaming or Boot Camp
Maybe everyone that is buying 3000$ computer should never take it out of it's shipping box at all, so that it will not get destroyed by use?PEOPLE STOP PLAYING GAMES ON MACS AND STOP RENDERING ON MAC
they are NOT designed for it.
We should really sue Apple. It is not hard to make a better coolling system....
Now that is some really good idea. This could change the situation. Anybody has an experience in such actions?I think a lawsuit is needed. This would curtail this illegal action.
I'm sure that
