I couldn't find any thread about this monitor here, it is supposedly the successor of Asus PA238Q. The specs (PA, PB) look identical apart from a different advertised contrast ratio.

However, what interests me is the anti-glare coating. Matte IPS monitors prior to this (PA238Q, U2312HM, etc) mostly came equipped with heavy coating. From what I understood this is not the case with all of the newest models though, such as the PB278Q which has been discussed in detail here.

Anyone who owns this monitor who could shed some light on this?
 
I picked up one of these from Fry's a few days ago and I'm pleased with it so far. Coming from an old samsung 20" TN panel (204b). The colors are great! No special calibration done other than basic tweaking using the test images at http://www.lagom.nl/lcd-test/

As for the anti-glare coating, it does seem that it may be more aggressive than the coating on the old samsung. It doesn't bug me though. I don't know the best way to measure this sort of thing but I snapped a couple pics at an angle with the camera flash to try:

I think you can tell the difference, but if you know a better way let me know and I will try to get a pic.
 
Update: I am returning this monitor due to a strange diagonal pattern in either the AR coating or polarizer. The pattern seems to be mini-gradients around 1mm wide running at 45-degree angles, mostly running bottom-left to top-right but it goes crosshatch at certain angles. It is most visible on whites and grays. Strangely, it seems to only be visible from a center, left-center or lower-left viewing angle. Viewing from the opposite angles on the right, the pattern is not visible. Also, Its more noticeable with less ambient light.

Its hard to notice at first. But now that I have, it bugs the hell out of me, particularly when reading or typing. I don't know if this is a defect in the application of the coatings or filters, or if this is the nature of this model (I've only had TN panels before). Comparing side-by-side, the superiority of the IPS panel is apparent over my old Samsung 204b, but there is no such distortion on the old TN.

Considering the research and paper writing I do, I must return this monitor.

I am looking at stepping up to a PA248Q. Any owners of these see any anomalies in the coatings from various angles? I hope that by going to a 1920x1200 panel that it might have completely different coatings. More vertical space would be useful too. Or perhaps it would be a better bet to skip to another brand of 1080?
 
I'm impressed with mine. The color is slightly on the cool side. Does Intel provide a color temperature utility for the HD4000 GPU? Or is there another way to calibrate the display panel?
 
Mine comes in tomorrow and I really hope it doesn't have the backlight issue that the reviewer showed (cross-hatching I guess is what they call it).

Aside from that reported issue, this seems like a great monitor for the money. I'll post back here with how it turns out for anyone interested.
