I have ez1 awhile. I notice the blue tint coz the left side is brighter than other on the screen . I feel upset . Sometimes I could notice it on the other hand mostly you would find it if you don't look for it. I have ex1 about 2 weeks and it runs about over 30 hrs I can't say it is bother when you watch contents. If I look or that yes it is there if I don't look for that I could not really notice but I already have known and noticed it Anyone has any experience about it ? Will it go away or less after awhile or I should get the new set. I worry if I get replace I may bet worse more than the one I had.. I put some content that I took picture before. I could not see it .
