3D Vision No Longer Supports Generic CRT Monitors in Stereo 3D

February 23rd, 2012 · 31 Comments · GeForce 3D Vision

If you have installed the latest WHQL GeForce video drivers version 295.73 you might have noticed that they no longer have support for Generic CRT mode that allows you to use an old CRT monitor in stereoscopic 3D mode. We actually got a hint that this is going to happen from the few beta video drivers made available prior to the release of 295.73, so if you still haven’t upgraded your old CRT monitor to a new 120Hz LCD display than maybe you should start thinking about it. Of course you can still use the old 285.62 driver that has support for CRT displays for a while, instead of upgrading to the latest drivers, however in a few months time you will start loosing some extra performance optimizations and new features as they get introduced to newer drivers. Up until the 285.62 driver Nvidia has been providing support for CRTs for legacy users, but they probably consider that it is about time to move on focusing more on 3D Vision certified products than on legacy CRT support. So the question is how many users are actually still using their CRT displays together with 3D Vision, anyone here doing that and not happy with the removal of the CRT support in the latest drivers?

    I’m still rockin two steam-powered 21″ Trinitron CRTs (and an un-certified DLP projector). So no Kepler for me then, damn shame, AMD here I come… ; )

  • 2 heyho // Feb 24, 2012 at 00:23

    Dam my 22┬░CRT was 8 years and work great ! i dont want to change now.
    I hope nvidia will do back.

  • 3 Tim // Feb 24, 2012 at 03:02

    This is just classic anti-consumer Nvidia. There’s no reason for it other than trying to sell a few more monitors. I bought your $250 graphics card and $150 glasses, now I have to get a new $500 monitor? My Trinitron works fine.

    That line about moving on and focusing on 3D Vision certified monitors is pure garbage. It’s not like they were doing anything to keep CRTs working. They actually did more work removing legacy support. Deleting unrelated code doesn’t make newer monitors work better.

  • 4 Bloody // Feb 24, 2012 at 03:08

    Well, the reason could also be the misuse of the CRT support functionality in the drivers for using not officially supported 120Hz 3D-capable LCD monitors with 3D Vision as well… ;)

  • 5 Rhialto // Feb 24, 2012 at 04:07

    I’m 4 drivers behind I think, because at one point it all messed up my 3DVision experience on my CRT, so I went back and won’t update until I get my… first… LCD. Oh well.

    Nvidia strikes again, instead of adding features such as CB and SBS, they keep removing ones. Every company survives from profits, but such negligence towards the consumers is sooner or later punished. It was punished when they stopped the support for legacy drivers (iz3d and DDD were born) and it will be punished when and if HD3D starts being integrated. Sadly the Alan Wake fiasco (declaring 3dvision support and not having even that) comes to show that Nvidia will remain the top dog of s-3d just because devs don’t care for integrating support. It’s good that the consumers have taken things into their own hands (helix) just like the old days, when KingDragon provided his tool for post-processing and pretty soon after that iz3d saw the light of day. It is one thing to monkey around consumers by not adding features, but to remove a feature such as this, and were are not talking about something which requires major support, that is just…. I for one am using a 3dtv, but I don’t see why people with perfectly capable crt monitors should be stripped of their right to use them with the newest drivers. This begs for a hack and I’m sure that someone will deliver.

    The major reason Nvidia ditched Generic CRT mode suppport in the latest driver is because they figured out this mode was a loophole to make the new Samsung LED 12ohz S27A950D work with 3D Vision.
    I own a S27A950D 27″ 3D monitor and is by far the best monitor I’ve ever onwed and I’m pretty sure it’s much superior to any of the newest lightboost 3D Vision 2 Ready displays, cause it’s glossy instead of matte screens, simple as that.

    The S27A950D works wonderfully with 3D Vision using the CRT mode with drivers 285.62, and the ghosting level is quite good in this monitor, much better than my old Alienware 120hz 3DV ready display. The 3D picture is very bright, it was a really huge step compared to using my Alieneware display combined with 3D Vision glasses. Samsung’s glasses uses bluetooth and has rock solid link, no interference at all and the glasses are very comfortable and light.

    Nvidia found out that some users like me have been using Generic CRT mode to play 3D Vision games perfectly with this monitor, and I’m sure that for business relations, not technical, they decide to stop supporting CRT mode, just to close the workaround for using 3DV with the unsupported Samsung new monitor.

    It’s a pitty that the S27A950D is not a 3D Vision Ready product and that Samsung decided to support the much inferior 3D gaming solution Tridef, cause it has all the technical requirements to work flawlessly with 3D Vision. I have this monitor and I’ve also been a loyal 3D Vision user for over 2 years, and this monitor made 3D Vision games look beyond amazing and it really adds a lot to 3D immersion.

    At least I can still use drivers 285.62 and play perfectly using my Samsung monitor with 3D Vision. I don’t use the Nvidia glasses anymore, but I have my Nvidia 3DV emitter connected to my PC always.
    I am trying differents 3D Visiob Ready EDIDs to make my Samsung 3D Vision Ready display. It is possible, but sometimes there are some bugs to deal using different EDIDs, but I was alreadsy able to make S27A950D 3D Vision Ready. It’s not perfect, but it’s possible to use it with the newest drivers. But if CRT mode was still there, no need for EDID tricks for sure.

    Bloody, thanks for posting different 120hz 3DV Ready monitors EDIDs. It’s really helping me out to find a solution for my Samsung monitor, so I can keep updating drivers and using 3D Vision along with it.

    It’s a shame to see CRT support be dropped, just as it was a shame they didn’t bring back DX8- and OpenGL support when they re-released the 3D initiative. I used my CRT for the first shot at 3D nVidia made (Elsa 3D Revelators from the very tail end of the ’90s) and always thought it was a shame they didn’t provide an update to the work they did back then (which later became a market segmentation issue as the Quadro/Tesla 3D Vision does have OpenGL support).

    While nVidia still seem like the best bet for providing value add, I wish they would stop removing features when it interferes with their marketing direction. With DX11.1 and 3D support beig baked into the API rather than the drivers within the year, they should be doing all they can to differentiate themselves as giving the early adopters the best they can rather than trying to restrict use of 3D Vision by removing features (and so forcing users to use old drivers, which in turn prevents those users from buying new nVidia cards as they (quite understandably, they lack forward compatibility) don’t support the new silicon in old driver).

    To help making your choise (French):

    Carefull with the last Samsung series like the S27A950D, it has no DVI port… only DisplayPort for 120Hz FullHD gaming and crosstalk is pretty strong on the Right side, less on the Left, but still here !

    Carefull with LG last serie monitors, they ship the screen with wrong polarized glasses (Cinema vs Monitor): Shame !


  • 10 David // Feb 24, 2012 at 18:46

    I updated drivers and 3D still works on my stunning CRT Sony FW900…

  • 11 claydough // Feb 25, 2012 at 00:08

    misuse? thats thinking in a very very tiny box cut out of the pettiest sentiment imaginable.

  • 12 Zerofool // Feb 25, 2012 at 00:24

    I still use a CRT monitor (22″ Mitsubishi Diamond Pro 2070SB), but I’m on the AMD side of the front. AMD HD3D has never supported CRTs, so I had to use a workaround to use HD3D – I used the .inf from this thread:


    ..which I then modified to include a few 4:3 modes I use in 3D:
    1280×960@120Hz, 1360×1024@120Hz, 1400×1050@120Hz and 1440×1080@120Hz (yes, my monitor can handle 1920×1080@120, although there’s no point, as it’s 4:3 ;)). And I chose one of those, depending on how demanding a certain game is in 3D. Here’s a guide how to modify the driver (huge thanks to my buddy artox for linking this to me):


    You can also generate a modeline for the default mode with this calculator:


    So 3D Vision users with CRTs might try this fix, even with future ForceWare versions, and hopefully it’ll work.

  • 13 Franco // Feb 25, 2012 at 07:04

    Martin M,

    Do some research before saying BS about the S27A950D, someone may believe you.
    I have the S27A950D monitor and it has a DVI-D and it’s true 120hz even in 2D mode.
    You must set the monitor’s response time option to normal to get very good ghosting level with 3D Vision games. The monitor is set to fastest by default and this option is unplayable for 3D Vision games cause it shows heavy ghosting. Once you set this option to normal, then you’ll have perfect 3D with 3x less ghosting compared to any 120hz 3D Vision Ready display.
    The response time option must be used while in 2D, in 3D this option is greyed out.

    I can’t compare the S27A950D to a 3D Vision 2 lightboost Ready monitor cause I’ve never used one. But I know glossy screens look way better than matte screens, so the S27A950D has a great advantage in colour saturation and black levels.

    Unlike you, I try to test things before assuming thoughts and opinions. I have this monitor right in front of me, and I’ve just played Batman Arkham City in 3D using 3D Vision 1080p120hz = 60fps per eye in Generic CRT mode using drivers 285.62.

    I’ve been a 3D vision user over 2 years, and I’ve gamed in 3D using a Samsung C7000 3D Plasma TV, Samsung 2233rz 120hz and Alienware op AW2310 120hz 3D Vision Ready display and I can honestly say the Samsung S27A950D is by far superior to these displays in 3D gaming with 3D Vision support.

    Seriously, you have no idea what you’re talking. The S27A950D works wonderfully well with 3D Vision, it’s just not supported by Nvidia, cause Samsung uses their own glasses and own 3D tech.

  • 14 Martin M // Feb 25, 2012 at 10:34

    My bad, in fact, the S23A750D has no DVI, sorry.

    Please, take a shot through your glasse from the TriDef test picture, and post the R and L side here.

  • 15 Franco // Feb 25, 2012 at 17:58


    I don’t know how a picture can prove anything in 3D. I don’t use Tridef and I’ve tried a bit and found it much inferior to 3D Vision, so I don’t have Tridef installed in my computer.
    You can’t use Nvidia glasses with the S27A950D, it looks horrible and blurried if you try to use Nvidia glasses. I do have the Nvidia 3DV emitter connected to my PC as a hardware dongle. I need the emitter to have access to 3D Vision.

    I’m using this monitor with the Samsung bluetooth glasses that came with the monitor and the link is rock solid, no interference at all, no bliking, flicker free, perfect 3D all the way. There’s very minor ghosting. Games like BF3, Batman AC and Left 4 Dead 2 look amazing with this monitor with 3D Vision. You must see to believe. I am really satisfied with my purchased, and I never bought cause of Tridef, I always knew I was able to use workarounds and use 3D Vision with it. It’s a 120hz monitor that supports Frame sequential mode, so it has all it takes in hardware requirements.



  • 16 Martin M // Feb 25, 2012 at 18:55

    The picture, is an SBS picture, it reveal the ghosting for each eye, you don’t need TriDef Software, juste a 3D player…

    FYI: You think you’re an “expert”, but I’m no noob too. I make mistakes, I’m just human. My apologises.

    I’m not the only one, no DVI mention on the Samsung Website (French):

  • 17 Daniel // Feb 26, 2012 at 14:27

    @Martin M,

    The LS27A950DS and S27A950DS are different “monitors”. The LS is a mix of TV and monitor and does NOT have a DVI port, while the S it a “true” monitor and have all three ports.

  • 18 Martin M // Feb 26, 2012 at 17:59

    Like Franco could say: BS…

    Look closely the page is about the S27A950D.
    LS27A950DS/EN is just the complete reference.

    Anyway, I still wait to see Franco’s picture with is low crosstalk, he promise he had on is “perfect” screen. LOL

  • 19 Franco // Feb 27, 2012 at 02:14

    Martin M,

    I’m sorry if I sounded rude, that was not my intention. I’m just sick of reading people’s comment about this monitor saying it doesn’t work with 3D Vision or that it has bad ghosting without even trying it first. That makes me mad, cause it gives this monitor a bad impression, and it’s the contrary, this monitor is truly amazing and has the best 3D I’ve seen so far. 3D in this monitor is very bright and really does a great job eliminating a good portion of ghosting compared to other 3DV Ready monitors I’ve tried in the past or my 3DTV.

    I’ve tried looking at the picture Tridef test you sent me and I’ve used the SBS mode in the monitor to view the image, no 3D player, cause I don’t require one since this monitor has it’s own 3D tech, it supports Frame sequential, frame packed, SBS and Under-over formats. I don’t know how to take a 3D picture, I also have the 3D Vision player, but I’ve tried Alt + F1, but it didn’t work for taking a picture, I think only in game I can do that.
    Anyway, I still don’t get how can you measure the ghosting level in this monitor if you don’t have one and will look at the 3D picture using your 3D monitor instead?
    I’m sorry my word is not enough for you, but like I said, I’m not an expert, but I’m also not a noob. I’ve played more than 30 games in S3D with 3D Vision and tried many 3D displays and TVs., and I’m telling this Samsung monitor is the Bomb!!!! It’s really good for 3D gaming, movies and all you ca think about. I just don’t recomend the 2D-3D feature and I woudn’t recomend this convertion feature for any 3D device outhere. For me this is just a bonus for 3D noobies and cause of this bogus feature, sometimes I see comments like this: The S27A950D is a great 2D 120hz display, but don’t buy it for 3D.
    You see what I’m talking, people don’t even know what’s real S3D, and they think it all relies in the crappy 2D-3D feature.

    I hope someday you get a chance of trying this new Samsung 3D monitor and will realize what I’m telling you is really true. The glasses are also very good and they don’t ever flicker or loose sync, bluetooth should be used for all 3D devices to replace old IR tech, you can bet on that.

    Sorry for my comments, I’m not calling you a noobie or anything like that, I’ve just told you to get know the product before saying it may have ghosting issues or that it lacks DVI-D.
    I am no expert either, but I am a 3D consumer and I own this monitor and I can tell you it works like a charm with 3D Vision in Generic CRT mode with drivers 285.52

  • 20 Martin M // Feb 27, 2012 at 07:14

    You have to use a camera, or even a cellphone, through your both glasses, you’ll have one picture with the L and a second with the R. Then just post it here with:

    See this french link, to find out:

    Carefull, do not switch the side of the 3D on your monitor/player, just use the both glasses.

  • 21 Franco // Feb 27, 2012 at 23:22


    When I get home after work I’ll try that.
    So, I open this picture in full screen and use the SBS mode in my monitor to active 3D, right?
    I’ve seen this picture in 3D before, to be sure if the 3D sides are correct, there’s little pop up in the Tridef logo image in the upper center, right? As thus picture has no depth, I just want to make sure I don’t have the sides swaped.

    So, let me see if I understood that, I take one picture from the right lens of the glasses viewing the pciture in 3D SBS and another picture from the left lens, correct? So, it’s just a regular 2D picture, no 3D picture right? I didn’t know about this method for measuring 3D ghosting. I hope it measures well, cause I;m telling you this monitor is quite good in ghsoting level, way better than other 3DV Ready displays I’ve tried and also my 2010 3D Samsung Plasma TV. It’s not 100% ghosting free of course, but it’s really good. I wasn’t expecting such a improvement when I bought this monitor, but it really astonished me, definatetly the best 3D quality I’ve seen so far.

    My 3D Vision games now look way better than I was used to play, the glossy screens also adds a lot for 3D quality and immersion in my opinion. I still don’t understand this lack of 3DV Ready displays with glossy screens. I’m sick of matte screens with heavy anti glare coating and ugly colours.

    I really would like to see the Asus AG278H + 3D Vision 2 glasses and compare the 3D quality with my monitor S27A950D and Samsung glasses. Maybe one day I’ll meet someone that has the new Asus, so I can know how good this Samsung monitor is.
    I read some comments in the web from people that tried both models, and they all said the Samsung is superior in all aspects, inclusing ghosting level. But I would like to see it for myself.

    I’ll take the pictures using my iphone and post a link here, so you can download it. The french instructions didn’t helped me, cause I speak no french.

  • 22 Franco // Feb 28, 2012 at 23:49

    Martin M,

    I’m not sure these are the right pictures you asked me to take. So, take a look and see if that satisfies your needs.
    I have no idea how these pictures can show the amount of 3D ghosting level in my S27A950D monitor, since they are in 2D.

    Here is the link: http://www.sendspace.com/file/59szop

  • 23 Franco // Feb 28, 2012 at 23:50

    Martin M,

    Here is the link for the pictures you asked me. I’m still not sure how these pictures can prove the amount of 3D ghosting level my S27A950D monitor has, since these pictures are in 2D.
    Let me know, how this works?

    Link: http://www.sendspace.com/file/59szop

  • 24 Martin M // Feb 29, 2012 at 18:08

    Franco, you have to take a shot the all screen, here you skip all the ghoting/crosstalk…

    Try to be in front of the screen.

    Take the shot through both glasses separatly, exactly like your two first shot (IMG_1498 & IMG_1499).

    Carefull, do NOT switch bouton Left/Right with the monitor/software.

  • 25 Franco // Feb 29, 2012 at 23:47

    Martin M,

    If it’s exactly like the two pictures I’ve taken, why I need to take more pictures? I even asked my girlfriend to help me out taking these pictures, to hold the glasses still while I was taking the pictures using my iphone 4S. It’s not an easy job to do. I can’t get the whole screen, this is the best I could do taking the picture from each lens of the glasses. I’ve tried many angles and possibilities, but I can’t have the whole screen, it will always get a portion of the screen. I was in front of the screen, that’s the only way I can take these pictures.
    I will try taking these pictures again from long distance, I mean 2-3 meters far away from my monitor, only them I think I can have the whole screen in the picture, otherwise it will be just a small portion. I took these pictures 1-1,5 meter away from my Samsung monitor.

  • 26 Martin M // Mar 1, 2012 at 18:15

    You have to take the all screen, take multiple shots if you cannot have it all in one !!! If you don’t want do it, don’t do it, just don’t play dumb…

    You have just skip the gosting, how convenient.

  • 27 JDS // Mar 30, 2012 at 20:11

    If they are going to keep with this “no more generic CRT” business maybe they should approve more 3D monitors. Im already wishing i could have gone for the AMD to just enjoy my dam Samsung monitor. Why not approve one of the best looking ones ive seen

  • 28 Bloody // Mar 30, 2012 at 20:46

    It is not a matter of approval, it is a matter of licensing and that costs money… if Samsung is not willing to pay the license fee, Nvidia will not just add it as supported product. That is just the way things work, nobody cares about the users when it is about money.

  • 29 Marc // May 1, 2012 at 07:33

    I read so much about the older driver 285.62 whql, so I installed that to get 3d with my Samsung S23A700d. But I still can’t find any option to generic mode. Where is that? And how is the button translated in the german version?

  • 30 utrinque // Nov 19, 2012 at 01:49

    Buying 3D Vision was A MISTAKE…
    My BRILLIANCE 202P4 works great in games.
    I go back to driver 285.62

  • 31 RG // Dec 20, 2012 at 00:46

    We use a CRT here at UCLA for molecular imaging. Dropping support for “CRT” in 3D Vision software is a disservice to Nvidias customer base. I dont believe that creating false barriers and trying to force market decisions through utility software is a productive strategy for any company. But when a corporation is not forced to compete they do just this kind of thing. Whether its greed and a desire to control or just poor judgement, its of no benefit their paying customers.
