I just purchased three Philips 23'' screens (234E5QDAB), and when I turned them on, I got a warning:
"Use of fixed patterns or static images for more than 30 minutes may result in image burn in!"
Since I have three of them, I don't always use them all.
For instance, I have a browser open on one, and playing on the other (for more than 30 minutes).
I never even heard of this before today, and I feel this should have been advertised as well.
I am reading that this is no longer an issue with newer screens (and that was back in 2011!!!).
Should I be concerned? Should I return them ASAP?
