M6600 IPS screen corner tint

Hello

My IPS screen has a fairly noticeably blue tint in the bottom right corner, and a less noticeable pink tint in the bottom left corner.

Does anyone else's screen have this?

It's only noticeable when the screen is showing white/grey but surely this screen is supposed to be the best you can get and shouldn't have any sort of tint at all?

I've compared it with my M6500 RGB LED screen which has no tint whatsoever.

Thanks

 

Your M6500 has a TN RGBLED panel which has no tint. The 6600 has an IPS panel and those, unfortunately, have the tint, something to do with the polarizer. I don't think there's a way to avoid the tint. However, some panels have less tint, so you can try and get a replacement.

 

Thanks for the reply.

I find it strange that this panel is supposed to have amazing colour reproduction, and be ideal for professional photographers, yet it is acceptable to have discoloured corners? Am I missing something?

In another thread I'm sure I saw people saying that their panels had no tint - maybe they just hadn't noticed?

 

I owned many IPS panels (both Elitebooks and Precisions) in the past and they all had some tinting. Some were better than others with a very minor "effect". I guess, some people are just less picky and never notice/pay attention. Like I said, you can always try getting a replacement from Dell and maybe you can score a better one.

 

Yeah, Dell are replacing it so will see if its any better - if it's worse, I'll get them to put the old one back in.

I can live with it if it's just how they all are, I'm just amazed that the issue doesn't seem to be mentioned in any reviews. It's supposed to be such an amazing screen for professional photographers and graphic designers but doesn't even show white as white??

 

To be fair, "white as white" is a flexible term. White is not that easy to nail down. You need to know the color temperature in Kelvin to measure the white point. MANY displays use a much cooler white to impress prospective buyers. But when you use a color calibration tool you'll see that they're too cool! My M4600 in an uncalibrated state shows reds too red and whites as too cool.

I'm also amazed that no reviews also point out the corner tints. I guess that many reviewers don't get the IPS panel with the reviewed unit, but only the standard FHD WLED display...
To be fair: Most color tints are hidden in the taskbar-area anyways, and that's where you usually don't do color-sensitive work. As long as the center area is ok I'm happy because toolbars are on the sides anyway...

 

I know what you mean about colour temperature etc, but im talking about a uniform "white" (even if it's the wrong white) rather than different shades of white on one screen.

I often use my screen for editing photos with no toolbars so the corner tints are very disappointing for a screen aimed at professional photographers... All that talk about accurate representation of whole colour spectrums etc sounds a bit silly when you've got blue and pink discolouration in the corners...

Is the IPS screen that much better than the WLED screen in all other respects to justify putting up with the coloured corners?

 

The IPS has higher gamut -> color depth. That's far more important than perfect whites. BTW, I think the tint is there because of the AG polarizer. If the screen was glossy you'd probably see no tinting. Not 100% sure though.

 

@jack574:
Gotcha! I guess I misunderstood your point then. You're talking about screen uniformity...
In that case I totally agree with you, although I don't run into this problem: I usually always have palettes/bars on one side or the other.
The cast usually only affects the lower sides of the screen..
To be honest, uniformity quality is something you can't put into numbers (thus "seeing is believing") and that's where laptop displays usually suck at... all of them. there's a reason why big eizo displays are that expensive.

 

I have an external LG monitor that isn't that good, but is still totally uniform. I've also got an HP external monitor (2211x) which wasn't expensive but to me looks at least as good as the IPS on the M6600, if not better - the blacks are blacker, and it is also totally uniform. The screen on my old M6500 was also totally uniform. I'm just disappointed that this amazing new IPS screen isn't!
