Asus VG248QE, VG278HE & HR, BenQ XL270T checkerboard-pattern in 3D-mode (no FullHD per Frame)
3 / 12
I feel light lightboost exaggerates the problem. Perhaps older active 120hz 3D monitors don't exhibit this because they aren't as bright? I can't say because the VG248QE is my 1st 3D monitor. I've also seen the theory that the matte layer on these monitors causes this problem in 3D. Has anyone else noticed that it also seems the depth of an object can impact how noticeable the problem is?
If this is an anti-ghosting technique then fine. I'll take this effect over ghosting any day. I just thought I signed up for full 1080p HD. So the problem doesn't exist on the VG278H? How is the ghosting on this monitor?

I have now tested the only thing left I could think of.
I think the pattern is connected to the contrast level in 3D mode.
When running 100 contrast and using the red-green test image there was no checkerboard pattern at all.
I run contrast values in the range 50-56 in practice so how this helps I really don't know.
I still Believe it is there to reduce ghosting.
It should be possible to configure the monitor not visible in practice or that would be ideal.

I made an image for you to test whether depth increases the checkerboard-pattern or not. The sphere on the far right should show more checkerboard-pattern than the one on the left.

For me the checkerboard-pattern increases the perception of ghosting, because it increases with increasing depth of objects (which are already likely to produce ghosting). Hence, I cannot see an anti-ghosting feature behind this technique.

I can reproduce your outcome and I can also see that every red sub-pixel is activated in that case (interesting isn't it?).
Here is a screenshot of the red-green test image at 70% contrast:

[u][b]In conclusion: The checkerboard-pattern can be ruled out by applying 100% contrast, but only for two constant coloured images. The pattern remains for every other 3D content. What a pity :(![/b][/u]

Theres way too many of us having it for it to not be intentional, its probably something to do with the polarization of the glasses or as has been said an anti ghosting technique. Though FlyingRocket your's does not look like mine, at least from the screenshots, couldn't hurt to return it, better than being stuck with it.

In the end, it seems this pattern exists on every 120hz active 3D monitor. Why? Who knows. I believe people who say they don't have it just don't what to look for or aren't looking hard enough. I hope this topic isn't spoiling anyone's experience with their 3D monitor. It's like checking out a buddies nice TV then pointing out a dead pixel that they never noticed. Now he'll see it from time to time and it may drive them crazy if they're slightly ocd :)
@FlyingRocket, thanks for starting the discussion and your screenshots that assisted in breaking down the issue. I've been surprised that there isn't much discussion on this topic out there. If 1080p 3D is advertised and the effect is not 1080p, I'd think more would notice. Similar to how there is a ton of discussion about LG claiming their passive 3D technology is 1080p when, in effect, it isn't.

Haha...Quadrophoenix spoiled it for me, it drove me crazy for awhile. Eventually, I wrote it off as normal.
I'm so glad it's been rehashed, other than the fact that I'm now being distracted by the phenomena while gaming once again...aarggg... good thing I use my PJ more than my monitor :)
The thought behind 3 stacked lines of red green blue that were no more than 1 pixel in height was that it would create 3 adjacent vertical rows of pixels in each color. You could then see the relationship that the position of the color filters have. When you show only a primary color, only one sub pixel is lit, hence the gap when showing all red. I always thought that the sub pixels were aligned in in a vertical row from top to bottom, but seing your picture makes me think they are offset/staggered on each row.

I almost wonder if the tsunami/eartquake is the cause? Perhaps manufacturers were in short supply of 120Hz monitor parts for production. So in their greed, they substituted a checkerboard solution to continue premium monitor profits?

Well.... I sent a message to ASUS and asked if they could fix this problem if I RMA. I described the checkerboard effect and gave them a link to this thread so they could read about it. Chances are they won't even visit the thread or give any decent reply but I figured it was worth a shot.

Please be aware: I still don't know if the checkerboard-pattern is a bug or a feature. Yet I go with the thesis that the checkerboard-interlacing is a bug, because there are counterexamples which (in my opinion) prove that there are monitors which support pattern-free 3D, like rustyks old non-lightboost monitors (see here).
Another counterexample has been provided by quadrophoeniX himself (see here). quadrophoeniX was the user, who originally started a discussion whether the Asus VG278HE produces FullHD in each frame or not, because his VG278HE showed the pattern artefacts. After a long discussion and directly contacting Asus he received a checkerboard-free VG278HE. Hence, as far as I am believing his story (and I really would like to), I think there are Shutter-monitors out there which do not have the checkerboard-interlacing issue.
Furthermore, if I go with the idea that every 120Hz only produces a Non-FullHD image within each frame, I wonder: what are the benefits of shutter-3D compared to passive Polarisation?
I thought the great benefit of Shutter3D is the FullHD for each eye. Taking this away reduces the differences between both technologies making passive polarisation more attractive. In fact, if I was okay with a Non-FullHD image, I could have easily taken a passive monitor and in addition get the benefits like cheaper glasses or less ghosting.
(Disclaimer: I know passive polarisation is not compatible with Nvidia 3D Vision and does not have 120Hz which make a game smoother, but in this thought experiment I just want to focus on the benefits for 3D perception).
Okay, after letting out all my disappointment (which is kind of relieving :)) I want to go back and find a solution for my problem, because that's why I am here :).
Problem: I do have a monitor with a checkerboard-interlacing issue.
Question: Where and how do I get a 27 inch FullHD-3D monitor, without this issue?
I am really thankful for any idea :).
PS: It is very hard for me to discuss in English, please be indulgent if I could not always find the right words or something like that.

Production date on my Acer GD235HZ Dec 2011/Samsung S23A700D March 2012
Conspiracy theories aside, if it's a firmware problem there isn't a ready solution to update/flash the monitor.
Either way, it seems like a class action lawsuit in the making.
