Hello guys, I apologize in advance for my English a bit 'out of practice!
I recently purchased three new monitors and TV range (nearly full Adobe RGB), an LG 27UD68P (IPS 10bit) and a Samsung UE43KS7500 (VA 10 bit) and a Dell UP3216Q (full sRGB coverage, but 99% of the Adobe RGB spectrum and 98% DCI-P3. It fully supports 10-bit colour, taken from a 16-bit look-up table). All three are totally unable to display the pure BLUE 0.0.255, have exactly the same colours.
My old monitor, it's a Dell 2407WP, it's really "expired", but it got a real pure blue!
Blue veer heavily to purple (you notice heavily on the blue-white shade) and there is no way to mitigate the problem calibrating them (I do not have a great calibrator, an old Spyder3 Elite that I use with DisplayCAL, but it works at least in sRGB)!
Everything that has to do with the blue sub-pixels (and therefore also the sky-blue and the intense purple),
I tried to solve the problem by changing the HUE from Nvidia control panel, but I just lost time.
With a pure Blue (and the blue gradient to white) I also tried to take some macro pictures to the sub-pixels to see if the purple was given from a red sub-pixel brighting for some weird error, but it is not.
Everything takes on a sort of appearance "wood light", nice, but really bad for the photo editing!
The pure cyan, is perfectly displayed on all those panels.
I find it absurd that today, so many panels with a similar lack are in commerce and that no one has noticed! (I searched online, but nothing, nobody talks about it).
The problem is not given by my accuracy or fussiness, is so obvious, that it even be photographed with my Note 4 (with an OLED screen, so with dynamics worthy of consideration, and one of the best pre-calibrated screens on the market). Of course, the problem in pictures made in this way looks very, very little in proportion to what you see with the eyes, and also strongly altered. I well know how absurd would be think to understand the problem using this method, but the fact that you see a strong difference between an old monitor with a real blue and all them, using a similar means of but the fact that you can see even with a similar means of shooting, speaks clearly about the extent of the problem, also given, even more so, that the blue are digital cameras (and for the monitors, i would say) the real weak point, always.
I spent hours trying to recreate the blue of the Dell monitor (that I keep next to the others) or the blue of the objects in my home and I see by eye on the monitor, photographed with notes 4, with a Sony A7S and a A7RM2 (only in the Note 4 photos you can see differences, the hyper sensitive Full Frames Sony cameras, don't show differences! I wont really comment this other absurdity!). no attempt has brought me even remotely acceptable results!
I find it almost paradoxical!
I add that I have a PC all in one Sony, with IPS panel (6-bit I think, by eye) some time ago, that absolutely does not show such a problem while rendering all colours well (it is not comparable with the quality of these new panels, for obvious reasons, but the colours are correct!).
I have sold the Samsung and I will sell also the Dell and the LG! Could someone please tell me a monitor that does not suffer from this problem?
Thanks for your cooperation folks, I hope someone knows enlighten me on this issue since I think I have some flaw in my knowledge, failing to deal with them.
