Any distortion will alter image quality whether you like to believe it or not.

Just take a look at the Dell U2711 and compare it when the Korean 27" S-IPS monitors. The Korean S-IPS monitors have much better image quality and also has color accuracy.

The Dell U2711 is still color accurate but the AG coating does somewhat decrease the accuracy.

The U2713HM would be a totally different ballgame but that's outside the scope of this discussion because Dell reduced the AG on that monitor.

Yeah, of course. But you overblow it. Macro images of the anti-glare is nice, but you don't see the subpixels. You can make an inference about "this antiglare looks worse than another one", but how much worse is it in reality?

Er. No. The Dell U2711 is wide -gamut - but that doesn't mean it doesn't have colour accuracy. It just isn't for sRGB. Saying that "it doesn't have good colour accuracy" when comparing the two screens is pointless without saying that it's for sRGB. I could, perhaps, say that the korean monitors have terrible colour accuracy for aRGB - and that would also be a perfectly valid statement. But it would be silly to say that. Of course, most people are using sRGB, but assuming that right off and making a blanket statement "THIS MONITOR HAS WORSE COLOURS THAN THE OTHER" is silly.

Patently false. AG does not reduce the accuracy of colours. The wide-gamut nature of the U2711 reduces accuracy of colours relative to the sRGB gamut. The AG is not responsible for this.

It is a big deal, which is why most of the newer mid-high end IPS panels sport reduced coatings. Companies are tired of dealing with all the returns and loosing money and are now using lighter coatings, HP even replaced the ZR2740W's aggressive AG with semi-glossy coating. LG's AG only became a really big issue in the last year, and LG just happened to change the coating within a year of this issue exploding on the internet. This is not a coincidence, just like there is a reason Samsung only uses semi-glossy coating on their PLS and A-MVA panels which came out last fall vs. the medium AG they use on their matte TN's and older S-PVA panels. These events are all tied together.

It (the antiglare "issue") is not a big deal. But yes, it was enough of an issue that thankfully, we have better antiglare coatings now than were used on the U2711. Was there a huge furor over the Dell U2711 not have USB 3? Since the U2713 has USB 3, it must be because a huge outcry over the lack of USB on the U2711, right?

As for the bolded, that's a huge assumption. Perhaps in your mind, it was a huge deal resulting in huge losses. As for what I've seen, this is far from the case. I would rather say that big monitor companies heard some complaints about anti-glare, and improved it. They did not lose any more money from these returns compared to returns from other sources. Definitely not a coincidence (the previous antiglare was pretty bad), but I would definitely say that your logic linking the two overstates the importance of the issue.

Sure I am assuming things but the sole goal of these companies is profit and for the most part they don't care about quality control...it is uncharacteristic for LG to suddenly start caring about something only a very, very, very small base of consumers knows about.

Recently we have started to see tons of reports from people who have returned their display simply because of the grainy AG, less than a year later LG started changing the AG...this is not a coincidence. I know I can not prove anything I say.

USB ports do not affect image quality.

Is it safe to say that basically any of the Korean 2550x1440 monitors will be a better choice than an Asus 27" LED or the HP?

If you want better image quality, yes.

The Dell U2713HM and the Korean monitors are the best choices if you want maximal image quality.

Yeah I saw an Asus IPS monitor a few weeks ago and it had poor image quality and backlight bleeding.

Hey guys,

I just received my Shimian QH-270 Lite and I am having trouble getting it to work with my laptop. I have an Alienware M14x with an Nvidia 555m runnning Windows 7.
I am connected to the monitor using a Mini Displayport to DVI adapter.

Using this cable: http://www.amazon.com/gp/product/B003OBXHPC/ref=oh_details_o06_s00_i00
I can get the laptop to recognize the monitor, but when I click "Extend these displays" it gives the "Unable to save display settings" error.

I have tried updating the Nvidia driver as well as disabling the TMM in the windows registry as I saw suggested in other threads.
I would appreciate any advice.

Thanks

Your adapter isn't the correct adapter you need. Unfortunately, you need the much pricier active dual link adapter.
