ViewSonic’s PJD6211 DLP Projector is the most affordable new model coming form the company that can work at 120Hz refresh rate and thus is officially 3D Vision compatible, which is a great news to all the current and future owners of Nvidia’s shutter glasses. This projector has a native resolution of 1024×768 and can provide you with a much bigger screen (especially compare to the 22-inch 120Hz LCD displays) to play games on, watch movies or view pictures in stereoscopic 3D and it does it quite well. Today I’ve finally got the projector, installed it and did some quick tests with it to see how good is the implementation and support for 3D vision and of course the projector in overall…

The installation and usage of the projector is pretty simple, but of course there are some issues that need some attention and getting used to, but once you do that you should be Ok with the product. I started with trying to use a long cheap VGA cable and I had trouble with setting up 120Hz which kind of surprised me, but I believe that the problem was something with the cable, because after switching to the shorter one that comes with the device there were no problems. Of course I’ve used a DVI to DSUB converter, because the videocard had only DVI outputs (Nvidia GeForce GTX 275), but there were no problems using the analog lines of the DVI interface for that.

So after quickly setting up the projector I went to the 3D Vision wizard to activate it with the projector, and here you need to select a generic CRT display in order to have things started. One thing that surprised me quite a bit was the fact that on the step, where you have to select which one of the two objects you see in each eye – triangle or hexagon figure, they were displayed just the opposite from what you should see. So I had to select hexagon where I actually saw a triangle for that eye and the opposite for the other to continue after this step, otherwise I just got the answers “wrong”, but after that there were nor problems with the 3D mode. Here I’ve tried the “3D invert” function, which supposedly had to invert the left and right frame contents, but it did not help… then again even activating or deactivating the “3D sync” option in the projector menu there was no visible difference and I could use without problems 120Hz with S3D in both modes. The documentation of the projector is not very detailed on these two options, but we’ll probably have to wait for a firmware update with some fixes and improvements, but as I said that is not a problem if you know about the issue and the workaround… ;)

I started with some well known games that work good and look very nice on the 120Hz LCD displays to have something to compare them and the results you get on the projector. Tomb Raider Anniversary and Underworld do look very nice as expected and much more fun to play when you don’t have to look like “through a small windows” which is actually your 22″ monitor. Counter Strike Source for instance did look better than on LCD display, but not that much… the game just is not great on 3D Vision, but still… Batman – Arkham Asylum Demo also looked very good on the projector, but with Prototype I had some issues with the character starting to be visible double even with the glasses if I increased the depth level a bit more than the lowest setting, and with the lowest setting it was Ok.

In other games like X-Blades that works very good on 120Hz LCD I had some strange issues, like the yellow and red coloring of some objects that you see on the picture, something that should not be present there. But then again that seemed to be some sort of weird bug, because later on I tried the game on another PC and there it was looking normal, without the strange colors problem, so who knows. Actually on that picture more interesting is the strange colored line of the bottom of the projected screen, as you probably guess it should not be there and it is not a part of the game’s visuals. I did notice this strange colored line appearing form time to time in different applications, so it is probably some sort of bug again, but it is definitely something that should not be there at all…

While setting up the projector I did notice that changing between the refresh rates does also bring some change in the brightness levels of the projected images. This is why I’ve decided to actually measure the brightness levels at 60Hz and 120Hz and got quite interesting results:
– sRGB mode: 60Hz – 457 lux, 120 Hz – 328 lux (~ 39% drop in brightness)
– PC mode: 60 Hz – 956 lux, 120 Hz – 461 lux (~ 107% drop in brightness)

So the higher the brightness level is in 60Hz mode, the more it drops when switching to 120Hz. Of course these results are measured in the center of a completely white projected image at 3 meter distance from the projector, and your results may differ in different conditions, but the change in brightness level in percents will probably remain pretty much the same in relation between 60 and 120 hertz modes. Visually the difference in sRGB mode (I prefer this one) is not that noticeable, but in PC mode it is much more apparent to the naked eye (when switching between the modes). However I did not find this to be an actual problem when playing in a dark room, probably it might be an issue if you try to play in S3D in s too lit up room, resulting in objects in darker areas not that clearly visible. Stay tuned for more things I find while testing the PJD6211 DLP Projector… ;)

    Great!

    How much more immersive is the effect given the large screen?

  • 2 Craylon // Sep 3, 2009 at 10:21

    oO nice article,
    – did you try movies yet ?
    – is there any difference in ghosting effects between the samsung computer monitor and this projector ?

  • 3 Bloody // Sep 3, 2009 at 10:23

    It certainly is better than the 22″ LCD, because you are not like looking through a small window outside – the weird feeling you sometimes get with the display. But as I suspected the game profiles probably need a bit of tweaking of the convergence for viewing over the projector, because the depth is Ok, but almost no pop-out effect or none at all.

  • 4 Damien // Sep 3, 2009 at 11:47

    Notice any gamma difference per eye? Close one eye and then the other and tell me if they are the same.

    I think I will try and get my PJ back tommorow for a quick test with another cable.

  • 5 Bloody // Sep 3, 2009 at 13:49

    Craylon, I’ve tried the demo movies Nvidia provides, but they did not look too impressive on the projector… tonight I’ll try with some field sequential ones I have to see if they will be better. On the projector I need to go for a lower depth level for the moment than on the Samsung LCD, but as I said maybe some convergence tweaking is needed, as the profiles are probably optimized for the 22″ displays.

    I did however notice something that looked like a slight brightness change on some darker images – it goes down a bit then it goes back to normal and this continues to repeat. I’ll need to measure if this is actually brightness change or maybe this is an effect of different gamma for instance in each eye.

    Tweaking the convergence level in Tomb Raider and X-Blades gave me a much, much more impressive depth/pop-out effect than with the default settings, so it seems I suspected right – the default profiles are made for 22″ 120Hz LCDs only… :)

  • 6 Damien // Sep 7, 2009 at 22:35

    Do you guys have gamma problems and blue ghosting? Gamma is a big issue, it makes one eye dark and the other normal, and the 3D result is very distracting. And blue ghosting just all around sucks, because just before the sync you can see it isnt there, and then final sync and then there it is. Im trying to work out if this is driver or projector related.

  • 7 Bloody // Sep 8, 2009 at 10:09

    No blue ghosting or gamma problems for me, but it might be partly the projector and partly from the person viewing it (the results vary from person to person). When experimenting with fast shutter speeds on the camera I can get all kinds of color ghosting on picture, but that is related to how the DLP technology works… because of the color wheel spinning fast in the projector.

  • 8 Damien // Sep 10, 2009 at 11:52

    Well I get one eye darker than the other (gamma) resulting in shadows very dark in one eye, and normal in the other. Also, I get the blue ghosting. I know its not me, Ive been using 3D for many years. But what I dont know is if it is the projector or the drivers. Obviously there is some sort of sync problem. Im RMAing this projector again, process of elimination. I want them to swap this for the one you have. You know, one that works properly!

  • 9 Bloody // Sep 10, 2009 at 18:00

    Have you tried installing the drivers/color profile for the projector, it might help (these are packed for all Viewsonic products):
    Standard_Monitor_Driver_Unsigned.zip
    Standard_Monitor_Driver_Unsigned_Win_x64.zip

  • 10 Damien // Sep 11, 2009 at 10:13

    I have, and they also didnt make a difference. The projector has been RMA’d now (again!). Viewsonic told me in the morning today that they would send me a replacement as soon as I bring the projector to the repair shop. So I did, then I called them back and it was a different person of course, who then proceeded to tell me that wasnt the case, and I would have to wait 3 weeks or whatever. Man I have had it with this company. I hope the new one is working well for you anyways, I hope if this isnt resolved with them they can send me the working model.

  • 11 Bloody // Sep 11, 2009 at 11:07

    You should always ask the person’s name when talking about things like that, it helps… :)

  • 12 Damien // Sep 12, 2009 at 00:54

    Yes well now Im in touch with a representative from Viewsonic and I hope she can help restore my faith in them

  • 13 Damien // Sep 15, 2009 at 07:58

    Great News!

    Viewsonic has decided since I had so much trouble with their support, they are sending me a pjd6221 and taking back the pjd6220-3D! Hurray. Lets hope the problems disappear now! Ill keep ya informed!

    Viewsonic = Win

  • 14 Bloody // Sep 15, 2009 at 09:20

    Great new Damien, lets hope you won’t have problems with the PJD6221. :)

  • 15 Damien // Sep 15, 2009 at 09:36

    yeah, with my luck….

  • 16 Damien // Sep 22, 2009 at 04:09

    Got the new PJ, but mine is reversed and stays that way. How did you get yours to display the right way? Great PJ tho, everything works great! No more problems at all!

  • 17 Bloody // Sep 22, 2009 at 11:55

    You mean reversed frames for left and right eye, right? For instance it shows triangle and heaxagon figures in the wrong eyes in the wizard. I could not find a solution for that. The 3D Invert function in the projector should’ve done that, but it did not help at all. But actually besides the issue in the setup wizard with “what you see is not what you should get” it is not a problem… ;)

  • 18 MeNaCe183 // Sep 25, 2009 at 17:31

    Have you tried experimenting with any tridef software to test compatibility with the nvidia glasses? if not is it possible you can visit tridef.com download their media player free trial and give the results of because the media player converts 2d to 3d in realtime using a advanced algorithm so your able to watch 2d movies in 3d compared to nvidia software that only allows you to play games in 3d.

  • 19 Bloody // Sep 25, 2009 at 22:18

    MeNaCe183, as far as I know the Tridef software still does not support 3D Vision, although it will probably work in OpenGL mode if you own a 3D Vision compatible Quadro VGA…

    hi;

    thank you for your impressions, i would like to ask that, is 120Hz (3D) only works in 1024×768 resolution , or can you force resolutions like 720p to run in 3D (120Hz)…

    thanks

  • 21 Bloody // Oct 30, 2009 at 19:57

    Unfortunately I haven’t tried to force it to run it in 720p resolution and the projector is no longer available to test it, but I suppose it might work…

  • 22 Darkbluesky // Nov 18, 2009 at 10:11

    Hello,

    About the brightness difference I would like to be sure about some points. In PC mode, I guess you measured

    1- With 3D disabled
    2- Not through the glasses
    3- Was the image projected in checkerboard pattern in 60 and/or 120 Hz?

    Tx

  • 23 Bloody // Nov 18, 2009 at 12:12

    When in 120Hz refresh rate it does not matter if 3d is enabled or not, the results in terms of brightness are the same…

    The brightness measurement is being made not from the point of view of the viewer, but from the surface where the picture is being projected on to… so it cannot be adequately measured through the glasses anyway.

    DLP projectors do not use checkerboard pattern like the DLP TVs, but instead rely on frame sequential method, just like the 120Hz LCD monitors.

  • 24 Darkbluesky // Nov 18, 2009 at 13:01

    Thanks for the answer, but about the checkerboard, that is interesting what you say, because almost “everybody” talking about the new 120 Hz 3D Ready projectors tell they use a checkerboard pattern, just because of the bandwidth limitation (probably the same limit than avoided the 85 Hz compatible projectors to increase freq).

    BUT, if you can confirm that you can see 1024×768 without checkerboard, then that is very good news.

    Could you confirm it to me, please? Tx

  • 25 Bloody // Nov 18, 2009 at 13:47

    Yes, I’m pretty sure the new Viewsonic and most other new compatible projectors do rely on frame sequential (time-sequential) signal… and there is more than enough bandwidth available to push 120Hz at 1024×768 resolution over an analogue DSUB15 cable.

  • 26 Darkbluesky // Nov 18, 2009 at 13:51

    Yep, I was thinking on internal circuitry bandwidth, but anyway…THAT’s WONDERFUL NEWS, although it’d be still xga.

    Thank you for confirming! Although I have already a sharp XR10X (85 Hz max) I am really tempted with these 120 Hz pjs…

  • 27 Ramy Fernan // Jan 26, 2010 at 21:52

    well i have been making alot of research on these projectors as i want to make at home a small cinema but to play movies in 3D and i was wondering if this projector can give me out put movies in 3D but any kind of movie will it actually convert to double frame and depth effect using polarized glasses
