Just for fun, I decided to run a test on my work computer with dual Samsung 23" LCD monitors (SyncMaster 213T) by cranking them up to max brightness, setting a dark gray wallpaper and leaving a window on-screen. One screen is always running my email app, so it should provide a good test for image retention. Unfortunately, the displays have a built-in energy saving feature and will turn off if I don't keep using the computer, but I'll try keeping it going for an hour and report back my results later today on whether there is any detectable image retention on a non-Retina display.
I can tell you that on my Apple Thunderbolt display, as well as an older Dell U2410 I don't have any image retention issues.
If I did, I can tell you it'd be a giant pain in the rear when working with Photoshop etc. as Photoshop CS 5.5 has a grey background, and Photoshop CS 6 has a darker grey background surrounding your working area etc. and trust me, you'd NOT want to be working on an image and only 20 minutes later be able to spot toolbars, or text etc. that hasn't moved for a while up on your screen.
This issue is especially annoying for those of us that use dual-monitor setups, and like to leave a couple apps (like Photoshop, or email etc.) up on one screen for lengthy periods of time. This is not acceptable at all having image retention/image persistence within 10-20 minute periods because users who do actual work (and who should be buying the 'Pro' series machines) will for sure be coming across these usage scenarios in real-world usage. Whereas on an iPad etc. it might not be a big deal at all, on a laptop-workstation it is a big deal.
I've contacted Apple support, and let them know about my issue and that it's being discussed on these forums and around the internet - the senior advisor had a chat with Apple engineers, and they will be giving me a call back tomorrow and from what I understand anyhow, they want my machine back directly for testing which I am happy to do!
So if what I heard was correct, it seems Apple has atleast acknowledged more than just a tiny fraction of their user-base has come across this issue with these panels. I also mentioned the LG versus Samsung preference it seems most have here.
We'll see what happens, but either way... I thought I had 0 issues with my LG screen only to find IR crop up 4/5 days later so I'd like to get this sorted out.
