Edit:

There is an issue with some (or possibly all) of these screens being supplied with the incorrect glasses.

Many describe it as purple ghosting, but for me, being colour blind, I can only sometimes say the ghosting is purple, but there is certainly ghosting.

You can test this by simply tilting your head 45 degrees to the left - if the ghosting reduces noticeably, you likely have been supplied the wrong glasses.

Myself and others are currently hounding LG to try and get to the bottom of this, but it's slow going.

Will update when I have more solid info.

Someone has set up twitter account dedicated to this problem. While I do wish he would calm down a bit, the more of us that join might help along this matter.

Apparently one of the responders to this twitter account phoned up and spoke to someone who stated they were aware of the issue, and were simply sending him the correct glasses.

In my couple of calls I have not spoken to someone who has acknowledged the problem.

My glasses were posted to LG and received last week (around 21 Feb or earlier) for them to test, but they do not have this particular screen available to them right now.

Just emailed them (28 feb) only to be told they were still with spares department and they couldn't give my any kind of eta

Apparently Potnoodles complaint was acknowledged by LG as an issue and they are sending him glasses once they have received copy of his receipt.

07/03/2012 Receive 2 sets of glasses from LG, along with a few other people. The glasses they sent were correct, and ghosting is all but gone. The glasses should read "3D monitor glasses" on side, not "Cinema 3D".

The boxes for both correct and incorrect glasses all seem to have model number FPG-200F, so based on that it's hard to tell if you have the correct ones or not.

I have still contacted Watchdog, even though they have sent me correct ones, because I don't want this to be a hassle for other people. I want LG to educate their support staff and to contact re-sellers of affected units to try and get in touch with purchasers where ever possible to get them correct glasses.

Update 16/03/2012

While some people seem to be finding it easier these days to get the correct glasses (LG are obviously becoming more aware of the issue), some people are still being made to jump through hoops for cheap glasses!

I am going to suggest to anyone who finds they have the wrong glasses to make a submission to Watchdog - Watchdog

Found this on one of the major etailers for what I consider a really good price, but having not liked LG products in the past was a bit dubious.

Anyway, had it couple of days now and must say am really pleased with it.

I didn't want an active shutter system - I just didn't like the idea of this flickering in front of eyes, no matter how quick.

Not had a chance to play all that many things in 3D, but tried Wipeout on PS3, Gears of war 3 on Xbox

Wipeout was pretty good and Gears 3 was better than expected.

On the PC had brief looks at Skyrim, Deus Ex, Dirt 3, Crysis.

Skyrim looks great, but performance is abysmal.

Deus Ex looked good, but struggled to find best settings.

Dirt 3 looked awesome, and was a pleasure in 3D.

Crysis just didn't like 3D at all.

I knew that 3D on PC would be hit and miss, with using Tridef (which came with tv/monitor).

Picture quality is above what I was expecting. Probably surpasses the iiyama 27" I just sold, which itself was pretty good.

There are tons of options for controlling settings very finely.

Overall, for £280, I think this was an awesome buy.

Can't wait to pick up uncharted 3 now :)

Think I'll do a little bit of a review on this. Info is quite thin on the ground.

Skyrim looks superb in 3D, so I am torn between playing it at 2560x1440 IPS, or on this screen.

Had a quick look at Dead Space last night, and that is great for 3d with everything being so claustrophobic, though shadows looked a little off to me.

Killzone 3 on PS3 was pretty rubbish in 3D. Far worse than the other 3D console games I tried.
 
I will give Pirhana a go in 3D this weekend and report back. Not expecting miracles on a 27" but guess it'll be alright.

One thing I have noticed, since updating to drivers which support 3D with crossfire, I have tried BF3 and DE:HR's in-built 3D support. But neither wants to run 3D at 1080p. If I drop to 720p is OK.

However, using just tridef, I am able to run 3D in 1080p.
 
Sorry, did say would report back on 3D movies. Did try piranha, and it was pretty decent.

I think a screen this size is better geared towards gaming though.

Though I think LG have supplied the wrong glasses with this set.

There was a this bit of purple ghosting going on, which was sometimes barely noticeable, but sometimes very noticeable.

Turning my head 45 degrees to left pretty much eliminated any ghosting when it was there.

Some research into this and other people have found the problem on the LG monitors. They use slightly different polarised glasses than the cinema or LG's larger 3D tele's

LG support was not much help, but I did get the ball rolling on returning the glasses for them to check.

In the mean time though, I have a pair of the Zalman monitor glasses on the way (should be here today) which apparently are the correct polarisation for these monitors. Once I have tried them, if I find they work properly, then will send others back to LG with detailed info and hopefully they can start rectifying this.

Despite this ghosting, I am still very much enjoying playing in 3D. Skyrim is excellent.

Though there are some games that either don't work well, or at all. Such as Crysis 2 - it won't let me enable 3d in-game, and using Tridef, the shadows look very weird.
 
The Zalman glasses I tried were the incorrect ones I believe.

Should have tried the ZM-SG100G, but got the ZM-SG100C.

Now I can't find the SG100G's anywhere for reasonable price.

I still need to post my glasses off to LG, but I guess because I have fashioned my own working glasses, I am in no hurry (but I really should get on their case)

Join the twitter of the guy above and voice your concerns too. More the merrier.

Uncharted 3 has to be one of the worst cases of ghosting I have seen in 3D. Apart from having the correct glasses, things you can do to reduce this are:
1) when in 3D mode in game, press "Qmenu" button on TV remote and adjust viewpoint all way to left.
2) In game settings, drop the 3D depth
3) On tele, try lowering contrast and/or upping the brightness.
 
Whats your FPS in 3D 1080p. I thought you was only limited to 24fps at that res, due to limitations in the HDMI spec?

I dunno know the technicalities of all this stuff. I know that I am supposed to be limited to 1080p 24Hz, but game ARE running 1920x1080 and at 60Hz using tridef. Don't know if it knows to only pass half the info through per frame or what.

Skyrim runs up to 60 FPS happily (capped by vsync), and it's definitely not misreporting the refresh rate, because 24Hz feels horrible for gaming.

However, like stated before, if I use a games build-in Amd HD3D support, I can not run at 1920x1080 at 60Hz - then it does indeed drop to 24Hz.

Used to love the HDMI spec once upon a time, but it is just far too limited for todays uses.
 
I do understand that about passive tech, but I don't understand why AMD Hd3D doesn't give me the same flexibility as Tridef - i.e. why does it only allow me 720p at 60Hz, where Tridef will allows 1080p at 60hz?

On a side note, how long before the new PS 3D monitors out? Have been impressed enough with this passive 3D screen (despite glasses issue) that I want to get one of the IPS screens when out.
 
I don't really have experience with AMD HD3D so I'm not sure. By PS 3D monitors do you mean the PlayStation 3D Display? If so it uses a VA panel, not IPS, and isn't supposed to be very responsive. For low framerate console gaming this isn't such an issue, but for PC gaming it is.

Sorry, typo, meant IPS - the new DM92, 82, 52 ranges from LG
 
Fingers crossed for the 27" :)

But am going to start to hounding LG now on the glasses issue, even if will be replacing with one of the new IPS screens.

Don't see why I should need to post them glasses. They should know there are two variants of polarised glasses.
 
Ok, if you are going to be keeping and trying to get the correct glasses from LG, then might be worth following the guys twitter on previous page.

I have been in contact with them over phone and online and posted off my current glasses yesterday.

The more of us that get on their case about this, the better our chances of them realising something wrong and helping us.

Unfortunately I think the reason for this is ignorance about more than one type of polarised glasses. Hopefully we can get them round!
 
Really? Wonder if got supplied the wrong kind, because when I got some Zalman glasses to try, tilting my head 45 degrees to left still reduced ghosting.

The Zalman clip-ons were awful though - they simply wouldn't clip on to any of my glasses. The LG clip-ons were far better.

Now, I know most talk about purple ghosting, but for me, most of the time I can not see any purple colouring, but definitely ghosting. Don't know if it's down to my colour blindness though.
 
Well, LG have received my glasses, and apparently should hopefully be getting tested soon.

The tech people don't have any of these particular screens at the moment though :(

Anyway, the support lacky says he has flagged issue for head office review, though not too sure on that.

One person has responded to aforementioned twitter account stating whoever he spoke to was aware of the issue and new glasses were being sent ASAP. Hopefully I will find out who he spoke to soon.

There seems to be a real disconnect with who knows what at LG...
 
hey guys, I've bought one of these monitors and it should be arriving with me on Tuesday. A thread about the glasses keeps getting mentioned but I can't find it. Can someone let me know where it is please?

Thanks

I think this thread has basically turned into the thread about the glasses.

When I get some solid info from LG, I will update the OP.
 
I have updated my review on rainforest site to 1 star.

I still like the screen, but it's getting on my nerves that something as simple as getting a cheap pair of glasses out of LG is becoming such a chore.

It just seems to be pot luck in who you speak to meaning you either get helped quickly, or not at all.
 
Keep hassling them by email and apparently they have correct glasses on order.

Not good enough though in my opinion. I want to be able to let others know how to get this sorted easily (like some have), and also want to be able to find out if they will be selling replacements somewhere - because what happens if any correct ones they send me get broken?

Will keep hassling them by email....
