GT750 Thread, HDMI 1.4 Capable - Page 5

One more.

I'm going to wait and see more reports before deciding between rf & dlp link.

Yeah, please post here if more information comes up. I might call Optoma and see what they have to say about this. He is using their glasses and projector.

problem is dlp link works good on that projector because it doesn't have white flash, don't know if this projector is the same. plus i have a feeling it loses sync with lights on and such and thats reality for me, light will be coming at the screen. the dlp is defninately enticing as its cheap. 3dheaven has them, 3dtv corp has two different types. optoma ones are getting good ratings on amazon.


oh, does anyone know the colorwheel speed of this thing.

I also want to find out the colorwheel speed, I can't find it anywhere, guess I could just call on the phone and ask.

If anyone does find out I would also like to know what the speed is on the HD33, wonder if they have the same speed.

If people are reporting seeing rainbows on the gt750, then it can't be that fast?

hd33 is supposedly 6x from reading the thread.

[Sorry, I had to remove all urls since I don't have three post yet.]


Here is what I have found:

On the Amazon page it says this projector is "NVIDIA 3D Certified" [Yes] [url omitted]

On the "Nvidia system requirements" (under "supported 3D projectors" > Optoma) page, it is NOT listed. [url omitted]

And, on the Optoma GT750E product detail page, it does NOT have the"nVidia 3D Vision" logo listed. [url omitted]

[See logo listed on this page:
(Logo means: "Projector is Nvidia 3D Vision certified to work seamlessly with 3D Vision to establish the highest quality and most diverse collection of 3D PCs available.")]. [url omitted]

Hopefully, Nvidia and Optoma have just not updated their info yet, and the Amazon page is correct.

I'm trying to confirm it will work with Nvidia 3D Vision, since this would be a deal-breaker for me. (In that case, I would have to go with the 3D-xl, and an appropriate projector.)

I have emailed Nvidia support regarding this issue, and have posted on the appropriate Nvidia forum asking about this. I will update here as I find out more.

Meanwhile, if anyone has any more info regarding this issue, it would be appreciated.

you are misinformed, it is a 1.4 hdmi projector so it can accept any format of 3d. 3dxl is not required with this projector, nor would it be on the vision list because it would work with 3dtv play.

even thought this is hdmi 1.4a projector, it only produce 720p 3d that mean it is downconverted 1080p to 720p.

Damn projector is gonna be sitting on the couch with me to project 135 inch screen. Thats a problem. Ill have to move couch back I guess. Can I put it under a table? I dont really want to ceiling mount where I am now.

750 has a very short throw - under 7' for a 135" diag. image. You should be able to put it under the table infront of you ...

7 foot 1 inch. that would put the projector on my couch if I drop the screen in front of the tv like i plan to. if I put it right at the wall, then its basically going to be bumping the couch, I can probably move the couch back, but i'll need a new table as the one i have now isn't with 4 legs, it has bars under it. so a normal 4 leg table with the projector under it would work? it wouldn't block light and stuff?

You would have to make sure you aren't placing the PJ one of the legs etc.

Ofcourse since the PJ doesn't have a Zoom, you have to move the PJ back and forth to get the correct image size.

damn PITA this is. I would go for the HD33 if it wasn't twice the price and going to need a remodel of the room to shoot the screensize I want. and by remodel I mean the room would have to be expanded to fit the throw distance.

I'm still waiting to hear on how 3d is before making a total decision on this, as that is my main reason for buying it. and if 3d doesn't pop out and does on the hd33, then i'll have to figure out how to make it work. really like the idea of an 800 dollar projector though because in a year or 2 when something much better is here, I haven't thrown out too much.

The 3d on the projector is great. Things do pop out,but it depends on the movie. Some have more than others. Things were flying at me all over the place while watching resident evil.

I don't know why the mention of 3d game up like it was going to be less than other projectors. It depends on the content

it came up because falafala went over and above to say how much better his 3d looks in 1080p on his new fancy projector then it did on 720P to the point to say that things didn't pop out of the screen at 720P and magically at 1080P pop out. so I've been trying to confirm if this is true.

Oh, I remember. Yeah, he just wanted to steer everyone away because he game on a pc, which can do 1080p 3D. Consoles can not, so why spent the extra money creating a 3D pc with a 3d 1080p projector. But it depends on the content anyways

i don't do any games, just want 3d popping out at me in movies which will more than likely be 720P rips anyway.

but this projector in theory should be much better for 3d because its much brighter than the hd33.

Much brighter, my GT720 gives me over 2500 lumens, so I'm sure this will be over 3000 lumens

I asked on the gt720 forum, didn't get a response, how is the 3d on your projector? it should be very similar. i don't have 3d in my face, i'm going to be disappointed.

A lot of content doesn't have stuff coming at you

true, but many movies do except green lantern but that was the worst 3d I've ever seen.

Is the depth of the 3D effect projector dependent? I understand that 1080 projectors will have higher resolution (for content that is in 1080), which can lead to increased realism, but wouldn't the depth effect be solely due to the content?

that would be my thought, trying to confirm.

pirates has a sword that comes out, either it comes out or not.

final destination5 has lots of 3d popping out as does pirahna 3d.

So how is 3d on the 750 vs the hd33?

What is the color wheel speed on the 750?

And is there any lag when videogaming on the 750? (it is advertised as a gaming projector)

I can't think of any reason why it would. All the projector does is display the two images it's being fed, nothing else. It's not aware of any depth.

What about the different types of glasses, link vs rf and all the different brands that make them?

I haven't really read up alot on the glasses, would some give better "depth" than others all else being equal?

One thing that definitely should increase the sense of immersion is the size of the screen, which this model should excel at.

the glasses shouldn't have an effect. im still not sure whether to try dlp link, they are really cheap so that is nice, but we don't know if this projector is red flash dlp link like the hd33, if it is then dlp probably work nicely except for the fact that bright light will cause loss of sync, and thats a problem when you have a wife that keeps turning the lights on.
