Asus VG248QE, VG278HE & HR, BenQ XL270T checkerboard-pattern in 3D-mode (no FullHD per Frame)
  10 / 12    
I imagine this issue is probably fixed with the G-SYNC upgrade, which probably uses some of its 768MB frame buffer for improved color processing (Advanced RTC, advanced inversion, advanced FRC, without any strobe-backlight artifacts). The G-SYNC performance chart: http://www.geforce.com/sites/default/files-world/attachments/GEFORCE-G-SYNC-Performance_Chart.jpg says the 3D mode is improved even further. Based on my tests with LCD's, I've become familiar with how difficult it is to combine all these simultaneously: - FRC (better 6-bit dithering) - LCD inversion (see www.testufo.com/inversion for explanation) - stable color during varying refresh rates. [i]Previous monitors 60Hz vs 120Hz vs 144Hz have color differences, so I can imagine how hard it can be.[/i] - Better strobe-backlight optimized overdrive. [i]Different overdrive curves are needed for bottom edge of screen than top edge of screen, due to different pixel freshnesses, since the LCD is scanned top-bottom in darkness, while strobe backlights flash all at once[/i] - All of the above can interfere with each other simultaneously! Avoid interactions between inversion/FRC/strobing (strobe mode) and inversion/FRC/varying refresh (G-SYNC mode). As demonstrated by this thread (inversion+strobing = sometimes problematic) Think of it this way; recent LCD monitors manage to clean up the refresh by about 99% before the next refresh. But cleaning the last 1% is incredibly difficult -- much like trying to get 99% of speed of light, to 100% of speed of light. Processing goes up exponentially. I'm imagining that G-SYNC's 768MB frame buffer plays a huge role in cleaning up the image, keeping colors stable through dynamic refresh rates, prevent inversion artifacts, prevent checkerboard patterns, prevent flickery color, prevent problems with strobing. Although strobing and variable refresh can't be done at the same time, both still require extremely complicated "color processing". I think G-SYNC will make 3D Vision users very happy; since this will mean even LESS crosstalk, too.

I am only hoping that this upgrade module will work with other Asus`s models. I have the previous one ( VG278HE ) to the one which been mentioned as a upgradeable.

I was hoping G-sync would clear things up as far as checkerboard goes and whatnot. Still seems wrong that we have to pay more to achieve the full 1080p 3D that is advertised. On my Benq XL2720T I get the checkerboard and when I run my mouse arrow quickly over a black background in takes on rainbowish colors. Now I need to consider whether to send it in for repairs or just wait and hope G-Sync fixes things. I've got a feeling that if I send it in, it will be returned with the same issues.

I have a Asus VG278H (vg278hr in control panel), my monitor has the checkerboard pattern :(

I have a vg278he and vg278hr as they show in ncp, both have this artifacting. Before both of these i had a non lightboost 23in asus monitor and this was not noticeable at all, I actually kind of wish i stayed with that monitor. I will probably add pics tomorrow.

Still hoping to find someone who can answer whether or not the G-sync DIY kit fixes this problem. I'm still on the hunt for a 3D vision monitor that doesn't exhibit this issue. I've been through quite a few and settled on the VG248QE but the issue is still present.

Hi, my Benq XL2411T have the same checkerboard issue in FullHD 3D mode with Lightboost activated, but in 2D mode with Lightboost there is no checkerboard artifacts, later i will make some pictures, but someone knows whats the root of the cause? maybe the Lightboost is the problem?

Well, there is definitely not a fix. All 3D vision 2 or lightboost monitors have this problem, as you can read in the thread, some worse than others. I'm pretty confident that those with lightboost monitors who say they don't have this issue aren't looking hard enough. Hopefully it will be resolved in 2014 monitors.

I just thought I would chime in here. I just received the Asus VG278HE and could not believe what I saw in iRacing. The above-track lights appear to blink on and off as I go around the track. Also flat white or gray ares in 2d appear as white ONLY pixels. In 3d, each white element becomse a Red-Blue-Grean pizel side bu side effectively reducing the resolution to 1/3 of what it should be. I haven't tried ANYTHING yet to fix it, but after seeing all the posts that ALL 3D monitors do that, at least to some extent, is not true as far as I can tell. I have a 4 year old Alienware 23" monitor and the flat white fields are smooth as glass, exhibit NO hint of the RGB pattern and made up of what looks like ONLY white pixels. And believe me, I am so nearsighted that without glasses I focus at about 4" from the screen and the pattern does not exist on the Alienware. Now to do some testing. Ok, I did a test. I fired up iRacing in 3D and paused it. Then I moved the cable to the Alienware and there was no pattern noticed in the white areas. This indicates that the graphics card/driver probably isn't doing anything weird but it does go to a blank screen for a few seconds, so who knows, the driver could be detecting the different monitor and changing something. Also, I'm not so sure I buy the light boost theory. Why would a white pixel in 2d become an RGB array in 3D? It could be the white pixel is already an RGB array even in 2D, but if it is, it is much, much smaller than the array I see in 3D. I thought it was supposed to be page flipping at 120Hz. It is being refreshed 120 times per second in 2D or 3D, so why would the monitor care or even know, it's a 3D image? It should just display one frame and then the next. I don't understand how that would cause a single white pixel to baloonn into an RGB array. I'm no expert. I'm just trying to figure out why my new $400 monitor looks worse than my 4 year old one. :-(

Can you provide some pictures showing the area's affected? Never seen anything weird here with iracing.

Sure. Not sure how soon I can get to it, but I'll take close-up 2D and 3D pics of the same scene on the Asus and the Alienware. UPDATE: I changed my mind. This monitor is only one day old and I'll be returning it to Amazon. For only a little more than this I should be able to find a couple of Alienware AW2310's and go with 3 screens. Thanks

...9 months later... ;) Hi Everyone! I've just read all 10 pages in this thread and... please someone tell me that there is at least one 1080p 3D monitor out there today because I'm considering buying one and the more research I do, the more it looks like there's not one GOOD 3D monitor on the market. The last relatively "good" feedback I read here was about the BenQ XL2720T - is it the only monitor in the market with a decent display that has the least checkerboard "syndrome" and good picture quality? Did anything better come out in the meantime? If so - I'd really appreciate some info, I've spent hours searching and I can either find G-sync monitors that only have a Displayport input and no HDMI (I need HDMI, for some reason) or 1440p monitors or... well, those from this list here marked as "with checkerboard problem" :-(

Currently, there are not any "3D Vision monitors" that will work via HDMI using NVidia's driver architecture. Some of the 3D Vision monitors with an "internal" emitter will work using the native stereoscopic support found in a handful of games via HDMI.

Sorry, I've said it incorrectly - what I meant was: monitors that have an HDMI input and also can to 3D vision. If they can do it via Displayport - no problem, as long as they also have an HDMI input so I can connect other devices to it (that only have an HDMI output like a Satellite receiver - just for regular 2D).

I use a VG278H, and I'm very happy with it. Quite a few of us here use the same.
