Got the LG 34WK95U, is anti-glare really this horrible?

[JesperA]

Got my 34WK95U delivered today, used it for a couple of hours, mostly awesome but there is one thing that annoys the hell out of me:

I have a horrible moire effect on light backgrounds like white and grey, i cant get a clean white or grey color, it ALWAYS looks like i have a layer of dust on the monitor, you know when your monitor have collected dust then when you turn the monitor on all the dust particles acts like a mini prisma, separating the colors in a rainbow effect.

Its like this ALL OVER the screen when viewing content on light backgrounds, like here on MacRumors, i also put tested viewing a random YouTube video:

which has alot of blue and yellow in it and all i saw was rainbows, moire and "noise" (kinda like grainy photos at high ISO, if you really crank up the ISO the noise pattern will change to various colors instead of pure black, looks kinda like chromatic aberration on every noise pixel).

I've had anti-glare monitors before and never had this issue, maybe its not the anti-glare film, maybe its LG:s "Nano IPS" stuff: "Nanometer-sized particles on the screen's LED absorb excess light wavelengths", maybe there is an issue with the alignment of the particles resulting in a grainy/moire image and does not work properly and acts somewhat like a prisma.

The issue only show on light background, so anyone else noticed this, either with this monitor or other monitors that uses the 3H anti-glare film?

That’s unfortunate. I had my eye on that LG monitor as well but I noticed the same thing with LG displays when I was shopping for a 4K display last year. I bought a Dell U2718Q and a LG 27UD68 and placed them side by side on my desk at home. The AG coating on the LG was a lot harsher compared to Dell’s resulting in a rainbow effect especially on white backgrounds. I used it for 15 mins and decided to return it because it looked terrible next to the Dell.
