Hi,
I want to know if there are any tests that I can perform to check if my laptop's display is IPS or TN.
Reason:
My laptop Lenovo Y50-70 1080p version came with an IPS display. 2 months ago It started to flickr and the screen would turn pink. So, I called Customer care and they sent an engineer to replace it yesterday, After 2 months! but anyway the engineer came and replaced my laptop's screen. Now, I get the feel that this display is not IPS because the viewing angles when rotating the laptop sideways are okay but the viewing angles when moving the lid up and down(or opening or closing the lid) gives terrible view. All the colors start to fade out pretty quick. Also, The display has an un-natural blue tint to it.
I use my laptop 14+ hours a day and do some work in photoshop and mostly programming. And this is very noticible.
I want to know if they did something fishy here or I am just seeing this because the display has been changed and it'll take time to get it natural..
I found one test on www.lagom.nl/lcd-test/black.php and the box outlines start appearing from box 8.
and this http://www.lagom.nl/lcd-test/viewing_angle.php the text starts turning light green on top and reddish when turning my display up and down very quickly.
Regards.
