LG 29EA93 Monitor Review - Rev. 1.25
by Chris Heinonen on February 12, 2013 8:49 PM ESTThe initial revision of the LG 29EA93 was very uniform overall, where I remarked, “For white uniformity, the 29EA93 is truly a cut above.” Despite this, LG was unhappy about the performance of the corners and went back and tightened the tolerances of assembling the screen to get better performance out of it. Unlike before, no areas drop below 180 cd/m² of light output, keeping the whole screen uniform within 10% when using the same 5x5 ANSI test pattern as before.
Light Output in cd/m2
Output Deviation Relative to Center
There are two points on the side that are slightly darker, in the same location as before, but the light loss in those areas is less than before. Overall the white uniformity manages to maintain its reputation of being great.
Black Uniformity is what had the issue before, with the corners having a lot more light creeping into the corners. This time that condition no longer exists. The only actual error that you can see is that one of the dimmer areas from the white uniformity is very dim in the black uniformity screen as well, but something being darker rather than lighter is a good thing.

Output Deviation Relative to Center
Now looking at contrast uniformity, we see the most impressive result for the 29EA93 yet. The average contrast value here is 1267:1, and the corners maintain a contrast level of 1252:1. This is now the best display I’ve seen in terms of contrast uniformity, with no areas of the screen that are a cause of concern to me at all. I really hope other manufacturers see what LG was able to do here with better quality control and bring that to their displays to provide similar results.

Contrast Ratio Deviation Relative to Center
For dE uniformity, I used the Uniformity tool available in CalMAN that can measure up to 45 points on the screen. For this display I used 21 points, in a 7x3 grid, which was a perfect match to the 21:9 ratio of the screen. The Uniformity tool isn’t completely finished yet, which is why I didn’t use it for brightness yet, but the dE uniformity is close to what we used to do, only with more data. Once the Uniformity tool is finished it’ll provide even better data, and I can go back to this review and update the graphs to match.
As you can see the center of the screen has very good color quality that we saw earlier. The extreme corners exhibit a bit of color drift with dE values that are a little worse, but only the upper-right corner moves past the 3.0 value that would indicate a color change that we can see. In comparison to the contrast numbers the color quality is only very good, but as this is the first display to be tested this way, it wouldn’t surprise me if this is the best display we see for a while and this method only accentuates the errors.
Colorchecker dE Uniformity
The LG 29EA93 was already a very good performer when it came to uniformity, and the improvements that LG made only increase that performance. The extra attention paid to make sure that the assembly of the extra-wide panel is done right has served to produce the most uniform consumer display that I’ve seen so far.

So when are you going to update your review? This is turning into a bit of a joke here, with you raving about a version 1.25 and nobody having the means to verify what version they're actually buying. I have a box standing in front of me. How can I verify whether it's the 'good' version? Without this info, this is a legendary bit of PR by LG, allowing them to sell off all their old stock.GeoffMorris - Monday, April 1, 2013 - link
I agree with Friso.LG needs to know that many find this situation unacceptable and all this doubt is no doubt putting people off buying the monitor. I tried to contact them myself but couldn't seem to find an email address for my country (Japan).
If they were so willing to work with you to iron out the issues product surely you have some way of letting them know that the situation as it stands is probably doing more harm than the 1.09 review.

Hey, did you manage to get that image? I'm really scared of shelling out 700 bucks only to get the crappy version =/jjj - Tuesday, February 12, 2013 - link
This is nice but in cases like this the review should be done on a retail unit just to be sure about what is in stores.The pricing is also way high , i imagine the AOC will retail at 500$ and that's still high but at least it's not 700$.
I do wish you would have more screenshots (gaming included) and a video wouldn't hurt, the AR is new , would help to see it in action.

I will try to get some screenshots of games if I can, though the site someone linked earlier does provide a good example of showing the differences in aspect ratios. As far as the AOC, it makes no sense to compared the LG against something that isn't released yet. Look at the large difference in how this updated version performed against the original version. We have no way of knowing which one the AOC will perform like, or if it will be better or worse. It will use the same panel I imagine, but that's only one element as we've seen here.As far as retail samples go, the initial sample was the foreign model as it wasn't out in the USA, and then the USA launch was delayed until the issues were fixed, so there was no possible way to get a review unit at a store. It also is cost prohibitive to impossible to buy samples, and with as many issues as every reviewer manages to find with the review samples, believe me, if there's an issue in the product, we're almost certainly going to find it no matter what sample we get.

I agree with jjj, it's more than a little concerning that LG hand carried a new monitor to you for a special review. How will a retail version compare to this hand picked one? Nobody knows.cheinonen - Wednesday, February 13, 2013 - link
They hand carried the initial model to me as well, if that makes you feel better about it, so I don't think that has any effect on the performance or what I find in testing.KLC - Wednesday, February 13, 2013 - link
Of course it doesn't have any effect on performance or what you found, I'm not impugning either you or your results. But let's face it, corporations exist to generate revenue, LG wants to sell monitors. What better way to sell them than to get positive reviews? Why is it startling to suggest that they may tweak a piece of hardware in order to get one?cheinonen - Thursday, February 14, 2013 - link
My question is how this review would be different than any other review then? Every display I've reviewed for AnandTech, aside from the iPhone 5 I bought myself, has been shipped from a company or a PR firm.I'm well aware of the fact that monitors could be sent that are ideal units, and so I attempt to read feedback from people that already own them on forums often to see what issues might exist to look for. To me, this unit is no more likely to be extra special than any other unit that comes in for review.
Look at every other review that I've written, positive or negative, and see how many other companies have followed up to find out what they can do to improve their performance and then attempted to do so. Even when I've received feedback, it's been nothing close to this, and typically more defensive than actually inquisitive about how to improve performance.
I'm certain someone else out there will buy a unit and test it and see if they match up. If they have a huge variance between them, then we can start to look into it more.

Reading the title I had no idea if you like the product.Not realizing or remembering that this is a followup article, and then reading the first few sentences, I was sooo close to just moving along and not waste my time reading a review of what I assumed was an absolutely horrible product.
I believe Anand usually puts some clue in the title of the review if there has been a major change in the product. This is not just a good idea for your readers, but also for yourself after spending so much time on this (you want people to read it, yes?), and LG for going above and beyond in getting this monitor right, which is extremely rare these days.
