ATI RAdeon mobility X1400 and EDimensional 3D Glasses

[Sylvain Menard]

Hi,

I would like to know if the EDimensional glasses works with ATI Radeon card?
I know that 2 years ago, it wasn't working well, but is it still the case
now? Unfortunately, I cannot change my video card because my machine is a
lapop (with an external LCD monitor). I would like to play World Of Warcraft
in stereoscopic 3D...

Thanks Sylvain

Edimensiion emailed me that they would work on my X1900GT card however,
when I asked similar question here a couple of weeks ago I got no
response- so I guess there must be a limited number of people using ATI
and these glasses. If you do order them ($40 from newegg is the
cheapest I've found) could you post a review?

Hi Sylvain,

I don't have experience with those glasses on ATI cards but E-D is saying
it should work.

You say you are using a LCD monitor.
When I bought these glasses about two years ago, the reseller told me that
LCD wouldn't work at all.
Looking at E-D's site they say: "Exclusive support for all video cards and
both
CRT and LCD monitors" so something must have been improved.

But I find this strange because those glasses need a very high refresh rate
to be
usable. Lower refresh rates might work but that gives a lot of strain on the
eyes.

Personally, I wouldn't use these glasses for a long period of time with
refresh
rates below 140Hz.

LCD monitors can only deliver 60 to 75 (or maybe 80) Hz.

Remember that those glasses work by alternately switching between left eye
vision and right eye vision.When the left glass is 'open' the right glass is
'closed'.
Doing this at just 60..75 Hz and knowing that each eye gets an image only
50% of the time...

Another note: this technology isn't perfect.

Many (if not all) directx games use 3d AND 2d images while drawing the
scenery. 2d images aren't translated properly and appear as if they are
floating
straight before your nose.
Especially annoying are the mouse pointer and effects like coronas around
lightsources.

So far I've only found one single game in which the glasses worked 99%.
and that was Myst URU (again, the mouse pointer was a problem).
Unreal tournament was also very do-able after switching off coronas and
adjusting the brightness of the game.
Don't know how 'real 3d' WoW is.. might work... might not.


regards,
Marcel

I looked it up at Newegg and the description of the product state that it
will work only with CRT monitor, I would like it to work with LCD monitor
and they dont seem to deliver in Canada. But the price is really much lower
than on the Edimensional site (69$).

LCD monitors can only deliver 60 to 75 (or maybe 80) Hz.

But with a LCD monitor of 8ms of latency, should it not give 1/.008s = 125
Hz? it would give 62.5Hz for each eye?

I once had a Asus Nvidia card with LCD glasses and I must admit that below
100Hz it was painful

This will have to be tried with WOW. I know that all the menu stuff will
float in the air.

I haven't seen any indication that the newegg glasses aren't exactly
the same as the ones on edimimensional. At the most you would need to
update to the lastest 4.X drivers if the newegg ones come with an older
version.

It might take 8ms for a pixel to go from one color to another but if you
can't
set the monitor actual refresh to 125Hz.

You are rightt. I suppose that finally, the only way to know if it is going
to work is to try it!
