Yeah it was probably the LED giving the blue tint, the DELL has been found to do that to. Sort of a down side to LED in general Unless you go with an RGB LED but those are crazy expensive. I had to return my first IPS236v due to a crazy green highlight in the top right hand corner, shocking it made it through QA (LG has crap QA from what I read, downside). I played the gamble on the return in hopes of getting something better and I did, the second monitor is perfect. No color bleeds and no backlight bleeds.
