My S2216H (bought 7 months ago) is showing a little reddish color from upper right corner. I noticed when, I increased it's brightness one day. PL see reference images. All brightness and contrast are at maximum with screen mode as paper. I recently bought another monitor S2218H same problem in it.
* Reset the monitor to Factory Defaults, page 28
* Post pictures of the standalone BID (Built-in Diagnostics), page 34, and I will tell you if it meets our manufacturer specifications for overall uniformity
Do the same testing for the S2218H.
