Yes I do believe it has an A-TW polarizer I notice no off angle glow.The back light- luminosity uniformity
appears good. overall. I do perceptual see some coating variation causing very slight winkled paper bag type clouding in the lower right corner (about 4by4 inch area)... with certain colors.
This clouding is jusst on the visual threshold of what im able to see.. thankfully its in a lower corner region that will only host the gui.. I imagine they use a pretty thick coatings on this.
(I desaturated the pic in PS. this photo as shown here is exaggerating the effect quite a bit from how it actually looks but I wanted to give you you an idea of what im talking about)..
Though I don't see any bad "sparkling" I can faintly see the grain structure of the coatings but only by purposefully trying to focus in on it. I have seen monitors where the grain structure of coatins are large enough to be visual distracting, this is not all the case on the 2690uxi2.Color uniformity Uniformity compensation is simply amazing.
Without the uniformity setting to off im jusst seeing a red bias on the left hand side vs right.. .. to test, im using a solid color of srgb(251,240,240). But then as I increase the Uniformity setting from off to 1 throuh 5.. it evens out to where I can no longer visuall or perceptually see any diff. the uniformity compensator definitly does its job! Ican't imagine any reason to not have this set to full.. except for gaming, video where youd want full brightness.. The uniformity control is absolutely IMO what makes puts this monitor into a pro-graphics level.. BTW, at uniformity setting 5, the brightest it can go is 170 cd/m2The black levels
with medium to low ambient lighting is looks like the monitor is off at full black. with lights out you can definitly see its got some luminosity but also there is zero bleedthrough whatsoever, clouding or edge flashlighting. when I say none I mean 0 nada, nothing, not even perceptually.Contrast is very good.
. The test is the best I have ever seen and turned to a luminosity of 130cd/m2 is so easy on the eyes I can look at it all day without strain. I waited for this monitor because of the 1000 contrast ratio. and am not sorry i did.The color and color ramp fidelity
is very good. To put it to test I put in srgb mode and put down patches of 255,255,255, 254,254,254 253,253,253 and can easily see each edge transition..
