Acer X34 (G-Sync/3440x1440) works with 3DVision, but there are issues...
Hi all, As an Acer's Predator x34 owner, I have been meaning to create this topic for a long time now for two main reasons. First, I want to clarify what the community here has been suspicious about, which is the fact (possibly) all G-Sync monitors are 3DVision compatible. The x34 is an ultrawide monitor with no mention of 3DVision, but if you have a 3DVision kit (pyramid & glasses), then by selecting 'Generic CRT display', 3DVision setup gets activated in actual 3D, which makes the Acer X34 a 3DVision compatible monitor. After searching the forums here, I saw one other person with an Acer XB271HU (G-Sync/IPS) that had success of activating 3DVision by connecting a 3DVision kit like me, so I think it's safe to assume that all G-Sync monitors are unofficially 3DVision monitors. However, in my case, there's an issue which prevents 3DVision from being usable at all, and that's constant alternating left-eye right-eye sync. Basically, both eyes show the correct image for around 10 seconds, then the images swap and I get left-eye image to my right eye and right-eye image to my left eye, then after around 10 seconds I once again see the two images swap which make them sync correctly for 10 seconds only for them to become distorted again after 10 seconds. FYI, my monitor's maximum refresh rate is 100Hz, and I am not sure if that has anything to do with the above issue. I did search through the internet but I could not find any solution, and because I don't understand the inner technicalities of 3DVision, I gave up on it. Though since there are a lot of intelligent people here regarding 3DVision, I am wondering if anyone here has any idea how to possibly fix the constant eye-swapping issue I have? Anyway, I thought this is worth sharing because this seems to confirm that future G-Sync monitors with high-refresh rate are very likely to be 3DVision compatible, so hopefully they fare much better than Acer's X34, but even then, I am almost sure that due to future (announced) monitors using IPS/VA panels instead of TN/OLED, they will still most likely suffer heavily from crosstalk.

How much have you played around with V-Sync in the global 3d Settings and games themselves?

Hi Optomaise, this is very interesting to know. I had a similar experience with Optoma UHD 40 projector. It's not advertised as 3D Vision projector but when plugging in the pyramid it is recognized as CRT Generic and 3D Vision works. However I had the same issue with eye swapping every 10 seconds. Not all games were affected by this but a lot. I found two ways to fix this: [list] [.]Close Riva Tuner Statistics Server. It causes eye swapping when limiting fps.[/.] [.]Enable DSR in Nvidia Control Panel. This somehow fixed the issue completely and RTSS can be still running. You don't have to choose DSR resolutions while gaming. It's only important that DSR is enabled in Nvidia driver. I still wonder why this fixed it but as soon as I disable DSR eye swapping starts again.[/.] [/list] How is ghosting on Acer Predator X34?

Really? Wow, any chance that AW3418DW is also compatible? I just picked up an AW3418DW to complement my PG278Q. To be honest, although curved 3440x1440 @ 120 Hz is truly amazing I actually switched back to the PG278Q whilst completing Hearts of Stone. Although 100 Hz or so at 3440x1440 G-Sync was buttery smooth, it pales in comparison to running TW3 in 3D. No comparison. At all. I'm currently in the market for a good arm so I can swing the PG278Q out of the way if the title in question doesn't have proper 3D support or just runs or plays better in 2D because of how demanding it is, i.e. No Man's Sky, Forza Horizon 3 (and 4) and Mafia 3 etc. Love the AW3418DW though, just not enough to ditch 3D. https://forums.geforce.com/default/topic/1058598/3d-vision/so-no-curved-21-9-3d-vision-capable-monitors-/

Update: I unplugged the PG278Q from the GPU and turned on the AW3418DW, NVCP > Set up Stereoscopic 3D > Stereoscopic 3D Display Type > Generic CRT and then Test Stereoscopic 3D and at first I was so excited to see my AW3418DW blink off and then back on with what looked like a rotating Nvidia 3D logo but when I put the glasses on the image refused to resolve. I tried powering off and on the monitor and repeating the test and then rebooting the computer and repeating the test and also cropping the refresh rate down to 100 and even 60 Hz and even reducing the resolution to 2560x1440 but no matter what I did the 3D doesn't resolve correctly. When you put the glasses on there is basically no difference. That's how it looks. But man was I excited, this would be awesome as then I could (assuming there the crosstalk or ghosting isn't that bad with the AW3418DW's IPS, as opposed to the PG278Q's TN) just box up the PG278Q and not have to worry about getting an arm for it to stow away when the game I'm playing doesn't have 3D Vision support / is too demanding for 3D Vision. Any ideas?

I can't comfortably test everything due to the eye swap, but from what I have tried, with around 10% depth and low convergence, plus selecting the OD Extreme option from the X34 menu will make games sort of playable, but personally I don't think playing games on X34 in 3D would be comfortable for long sessions, even if the eye swapping issue was not present. Honestly, around a year ago I decided to buy 3D Vision glasses (as I already had the pyramid) just to test out whether all G-Sync monitors are 3D compatible or not, and I feel like my expenditure partly led to a successful result because the monitor is most certainly 3D compatible, but unfortunately in my case it's not usable mainly for the eye swap issue, and also the rather excessive crosstalk (though I am very sensitive to crosstalk and I find it infinitely more distracting than the lower resolution of 720p 3DTV option of 1080p projectors).

Though personally I wouldn't recommend buying one of these expensive monitors for their potential 3D, but if someone is planning to buy one anyway, purchasing a 3D Vision kit might be worth it to give the 3D a shot.

If you don't have any kind of strobing available (Lightboost, ULMB, etc), crosstalk is extremely high. Like, you'll see both full frames (or most of them) with both eyes. You can try to focus on the correct image, but it's almost impossible. I have tried it with my PG278QR at 165Hz, for example. ULMB, while not ideal (worse regarding overdrive), at least lets you see each image separately.

Truly love both of these monitors.

I have tried some stuff, such as playing around with V-Sync as you have suggested, but the eye sync swap remains no matter what.

Just to be clear, even outside of playing games, at any point when the 3DVision glasses turn on and 3D is active (such as the 3D Stereoscopic Test from NVCP), the constant swapping happens.

Pauldusler said:Hi Optomaise,

this is very interesting to know. I had a similar experience with Optoma UHD 40 projector. It's not advertised as 3D Vision projector but when plugging in the pyramid it is recognized as CRT Generic and 3D Vision works.

However I had the same issue with eye swapping every 10 seconds. Not all games were affected by this but a lot. I found two ways to fix this:

  • Close Riva Tuner Statistics Server. It causes eye swapping when limiting fps.

  • Enable DSR in Nvidia Control Panel. This somehow fixed the issue completely and RTSS can be still running. You don't have to choose DSR resolutions while gaming. It's only important that DSR is enabled in Nvidia driver. I still wonder why this fixed it but as soon as I disable DSR eye swapping starts again.


How is ghosting on Acer Predator X34?

Thanks a bunch for your input Pauldusler (and of course, for your excellent 3D Fix Manager tool).

Based on your above description, I think it's safe to say that your projector and my monitor behaves differently when using the pyramid and the generic CRT display option.

In my case, the eye swapping is constant and has nothing to do with games per se. Everything from video, pics, to all types of games suffer from that issue. I don't have RTSS downloaded so that can't be the culprit, but I have tried playing around DSR settings based on your suggestion, though unfortunately everything acts just as before.

I imagine in my case, it has something to do with the 100Hz (overclocked) refresh rate acting up some of the driver's registries regarding the image sync, and due to my lack of knowledge on that matter, I am quite pessimistic on ever finding a fix to this eye swap issue, but I still really hope there was a way to get this issue sorted so that I could test out the 3D properly.

Though it's worth mentioning that the ghosting is pretty severe on that monitor, to the point it's almost unplayable on medium depth and convergence. I can't comfortably test everything due to the eye swap, but from what I have tried, with around 10% depth and low convergence, plus selecting the OD Extreme option from the X34 menu will make games sort of playable, but personally I don't think playing games on X34 in 3D would be comfortable for long sessions, even if the eye swapping issue was not present.

Honestly, around a year ago I decided to buy 3D Vision glasses (as I already had the pyramid) just to test out whether all G-Sync monitors are 3D compatible or not, and I feel like my expenditure partly led to a successful result because the monitor is most certainly 3D compatible, but unfortunately in my case it's not usable mainly for the eye swap issue, and also the rather excessive crosstalk (though I am very sensitive to crosstalk and I find it infinitely more distracting than the lower resolution of 720p 3DTV option of 1080p projectors).

Anyway, I thought it's worth sharing this information now as we're about to see multiple high-refresh rate monitors hitting the retails, such as 4K 144Hz models, and 3440x1440 ultrawide monitors at 200Hz, all coming equipped with G-Sync. Though personally I wouldn't recommend buying one of these expensive monitors for their potential 3D, but if someone is planning to buy one anyway, purchasing a 3D Vision kit might be worth it to give the 3D a shot.

I unplugged the PG278Q from the GPU and turned on the AW3418DW, NVCP > Set up Stereoscopic 3D > Stereoscopic 3D Display Type > Generic CRT and then Test Stereoscopic 3D and at first I was so excited to see my AW3418DW blink off and then back on with what looked like a rotating Nvidia 3D logo but when I put the glasses on the image refused to resolve. I tried powering off and on the monitor and repeating the test and then rebooting the computer and repeating the test and also cropping the refresh rate down to 100 and even 60 Hz and even reducing the resolution to 2560x1440 but no matter what I did the 3D doesn't resolve correctly. When you put the glasses on there is basically no difference. That's how it looks.

But man was I excited, this would be awesome as then I could (assuming there the crosstalk or ghosting isn't that bad with the AW3418DW's IPS, as opposed to the PG278Q's TN) just box up the PG278Q and not have to worry about getting an arm for it to stow away when the game I'm playing doesn't have 3D Vision support / is too demanding for 3D Vision.

Any ideas?

[quote="masterotaku"]If you don't have any kind of strobing available (Lightboost, ULMB, etc), crosstalk is extremely high. Like, you'll see both full frames (or most of them) with both eyes. You can try to focus on the correct image, but it's almost impossible. I have tried it with my PG278QR at 165Hz, for example. ULMB, while not ideal (worse regarding overdrive), at least lets you see each image separately.[/quote] Yeah I believe the issue is that AW3418DW does not support ULMB. Sad face.
