Is there anything that's in the pipeline for this on the PC?

Not a fan of the active 3D setups - would much prefer using the passive glasses even if it took a bit more tech on the PC. I've heard of a couple of attempts but is there anything going seriously in this direction or are we locked in to nvidias solution?
 
Nvidia's 3dvision is active 3d. It requires a 120hz monitor and a pair of active glasses that open and close LCD shutters over your eyes to create the effect.

Passive 3D requires a polarised screen and a pair of regular polarised glasses.

Tridef (Amd advises to use this with their cards) was designed with passive 3D in mind. So basically the effects are not as strong but the performance hit is a lot less and you don't have to be subjected to flicker

disclaimer most this information was pulled from fallout3 on avforums.
 
LG has some nice looking IPS monitors coming out, which like their current offerings like the LG DM2780D includes Tridef.

When it comes to choosing between playing Skyrim in 2560x1440 or in 3D, I typically go with the 3D.

Though I don't think LG have supplied the right glasses - there is more info on that in monitors section.

I will more than likely upgrade to one of the IPs passive 3D sets when they out :)

I paid £170 delivered for mine. Comes with two sets of glasses (one clip on one regular) and Tridef 3D. More on that here.

I must say I am very impressed with it. Fallout 3 and Half Life 2* in particular offer a whole new experience.

* Half Life 2 had some teething issues on early levels where if you stand too close to a wall the wall goes odd. It seemed to stop it later on though. However you can switch it from the profile 3D to virtual 3D.

I did do a write up...

It's not perfect, but then for £165 (it's gone down a fiver since I got mine) it's an absolute bargain. It does lower the resolution but I have found that setting it back to 1080p in the game's menus works fine (though it does add some slight ghosting but nothing serious).

The best part of course is that it works, really well. And only costs £20 or so more than a regular monitor.

There is a comparison here mate. Well worth a read, great article.

Hope you find it helpful :)

Quick mention of Dirt 3 - immense game. The dash looks so real you can almost reach out and stick your hand on it. Doesn't help though, I kept crashing :D

Hmm.

Theoretically it should run on an Nvidia. Unless of course they spat the dummy and blocked it in their drivers.

Wouldn't surprise me at all tbh.

Will do some research.

Improved NVIDIA 3D Vision interoperability

Fixed an issue that caused Call of Duty: Black Ops to crash on some systems with NVIDIA graphics

Just noticed this.

Some 3D displays require AMD HD3D Technology and therefore cannot be used with NVIDIA graphics cards.

So I guess you could always send it back under DSR. The place I got mine from (without mentioning names) will return collect so you don't even have to post it out.

not sure it's down to NV;

TriDef 3D supports Line Interlaced (FPR) displays, HDMI 1.4 3D TVs/monitors (if your graphics card supports AMD HD3D) and Anaglyph glasses. Please also ensure that your PC meets the System Requirements.

If that is saying that tridef over HDMI requires AMD HD3D then it won't work on mine

also just looking at the tridef forum, seems to be massive issues getting BF3 to work with TriDef

Post 3.

maybie not, i looked lg faq and they had a solution.
i updated to latest tridef version (with better lg support)
and reseted the screen osd to factory settings.
it fixed most of the ghosting problem!
after this i played a bit more with tridef and now the result isnt so bad after all.
it work corectly with most suported games and for the unsuported one, the virtual 3d isnt so bad after all.
i noticed too a prety performance jump in games in latest version .

The ghosting (I read about it) is apparently down to the poor glasses they give you. Some have bought Zalman glasses and reported back that the ghosting was gone.

TBH it ghosts on my 7970, so it's not an Nvidia problem. It is acceptable though, especially at that price. Just don't expect a grand's worth of screen and you'll be very pleasantly surprised :)

Edit. This monitor comes with Tridef lol.

It's six of one, half a dozen of the other.

Active offers more pop out. However, pop out ruins a game as it's too distracting.

Active means flickering over your eyes, meaning some will be subjected to motion sickness and dizziness.

Active means a huge performance hit, passive far less so.

Passive needs a light pair of polarised glasses, active battery driven shutter glasses meaning no clip on so if you wear glasses already you're screwed.

And so on. Read the Tom's hardware link as it pretty much says it all.

This is false. 3D Vision 2 fits perfectly well over my glasses, even though my lenses are pretty big as far as glasses go. And it does not flicker. It alternates 120 times a second -- this is completely unnoticeable. The reason people get nausea and dizziness using 3D is not specific to active 3D. In fact I've only ever had it with passive 3D at cinemas. The reason people feel these effects is because the brain has to work twice as hard trying to interpret what the eyes are seeing. (Exacerbated if one of your eyes is weaker than the other. This can happen with BOTH types of 3D. I can't stress this enough. But with that said I've only ever experienced it at the cinema which happens to use passive 3D. When sitting close to my monitor with active 3D glasses on I've never had headache or nausea issues. These things can affect different people differently, but to claim that active 3D causes flicker or that it is responsible for dizziness, headaches or nausea is patently false.)

And pop out isn't distracting. It's the reason you use 3D in teh first place. The pop out is incredible. Magical. Immersive. Passive 3D is the poor man's 3D. Active 3D is in every way superior.

And as for the performance hit, if you're that concerned just halve your resolution (which is precisely what passive 3D does!) and you will have equal performance.

I'd rather play full resolution and have the alternative of a silky smooth 120Hz display when not using 3D. I could never go back to using a 60Hz desktop. So I say no to passive 3D with its poor ressolution, ghosting and all that other crap.

3Dvision is active.

And of course you say all of that because you own 3Dvision.

Probably just a good idea for people to read over the Tom's HW article and make their own mind up given that it's completely honest and not biased due to owning one or the other.

Hi guys,

If you have a HDMI 1.4 passive 3D monitor then you should be able to use it fine with an Nvidia card and Nvidia 3DTV Play software - as in this configuration it treats such a monitor as a 3DTV.

However, the real issue with playing games on a 1080p passive 3D monitor that can only do 3D via HDMI is the bandwidth restriction of HDMI (and the only connection I have seen passive 3D monitors use is HDMI). This connection only allows 3D at 1080p@30Hz or 720p@60Hz.

In contrast, if you got a monitor that does 3D via dual-link DVI or displayport (which have much more bandwidth than HDMI) then you can play in 3D at 1080p@60Hz (per eye), so achieve a better gaming experience so long as your graphics card can keep up (a GTX 480 should do well).

Passive 3D, watching a movie/footy with 6 friends at a cost of ~£20

Active 3D, watching a movie/footy with 6 friends at a cost of £:eek::eek::eek:

By my reckoning active 3D is not superior in every way at all when you look at the big picture regarding 3D playback, it's not only about playing games mate.

When you can buy a 3D monitor with 2 sets of glasses for less than £160 and have a drawer full of 3D movie glasses, it opens it up for a whole lot more folks that can't afford to throw a lot of money down on a purchase.

Anything software driven comes with problems, there's just no getting around it.

For the sake of the popout crew though read through my review. Crysis for example pops so much that you can't see what the heck is going on and completely (IMO of course) ruins the game.

Getting shot to death with great big blades of grass coming out of the monitor isn't a good experience IMO. Whilst it is very strange and visually impressive it totally distracts from the game itself.

I know several ex 3Dvision users and all of them say the same thing.

"Nvidia's spinning logo is about as good as it gets, but it's all downhill from there"

I admit that I don't play some of my games in 3D. It's just too distracting. Alan Wake for example has scenes where it's hard enough to see where you're going as it is, so I made sure to complete it all before I try in 3D.

Fallout however? well given that you do most of your aiming in VATS 3D takes it to a whole new level.
 
Both Nvidia and AMD can support either active or passive.

That Toms hardware article from what I can see is comparing active on both - not active vs passive.

And don't assume that cinema 3d glasses work on all sets - as myself and others have discovered, there can be at least 2 different kinds of polarised glasses and LG has been supplying the wrong kind with the likes of the DM2780D.

You can test this be tilting your head 45 degrees to left and ghosting will all but go away.

They did it with the D2342 as well.

Which apparently is what causes the ghosting. As I mentioned people have been switching to Zalman's polarised glasses and reporting perfect results.

Sadly I can't as they are glasses and not clip ons, though tbh I only get ghosting in Left 4 Dead 2 and apparently that's a known flaw in the profile. I did switch to Virtual 3D but it was nowhere near as good and it's only the lamp posts that really ghost with the zombies themselves looking perfect.

Pipe bombs are absolutely hilarious. Chuck one and then stand as close as you can :D

Sparks dropping from powerlines are incredible too, and do jump out of the monitor. And the fireworks? they'll stop you in your tracks that's for sure :)
 
here this is passive 3d ive tried it with an trackir head set a while ago and a wii remote and it works better with a proper track ir camera tho tbh

google Head Tracking for Desktop VR Displays using the WiiRemote by johnny lee

again just google TrackIR 5
