You got a link for this? I don't feel like asking or searching. I pretty much read that whole thread (over time) and did not come away with that impression as a whole or even as a problem. Maybe I missed it.

Really? Couldn't find a real pick?
People that are curious what the screen door effect actually looks like try this pic http://en.wikipedia.org/wiki/File:Sc...oor_effect.jpg

Don't be a smart ass. I found that Wiki photo earlier when I made the post and it was extremely large, so I Googled and found that simulated pic. What's the difference? Point was made whether it's simulated or "real".

Now that I'm at home and on my home PC, the pic is now formatted smaller for whatever reason.

Yeah I saw it with my GT720 that I returned because I never got 3d working. At a distance it was not noticeable but the 720P was as I made the picture bigger. That is why the GT750 is probably out for me now since reasonably priced 1080 units have arrived. Not 100% on that but 1080 units definitely look better on the big screen.
post #275 of 619
Well a picture someone took out a window using the bug screen to simulate the effect is not really representative and is somewhat misleading. The "screen door effect" is inherent to the DLP technology due to the necessary space between each mirror. For those unfamiliar with DLP technology watch http://www.youtube.com/watch?v=eD_xZcYQE50

Which glasses are reccomended for 3d on this projector? All i know from reading is it flashes white?

Pictures taken from an iPhone so forgive the quality. I'm yet to play around with the colour gain/bias if anyone has the gt750 and has done so how did you get on?

sorry I don't, i remember reading it a while back in the thread, i'm probably going to go for a refurb denon if I swap the receiver as they seem to work, but the sony's no one seems to be having luck with, I think its the projector, probably going to need and EDID hack or something. funny thing is, people using the 1.3 receivers seem to be having less problems.

Thank You for the pictures. I am just getting mine up and running. Do you mind sharing any of your settings? I think your images look very good, and would like to have a starting point

Hi, my current settings are... Display mode user, brightness 1, contrast 4, sharpness 8. In advanced display I'm using film degamma, brilliant colour 8, colour temp warm. I haven't touched the colour gain/bias as of yet. Hope this helps

The white flash you're referring to is when you have the projector set in DLP Link mode. This flash is what makes the DLP Link glasses work in 3D. Consequently, you need DLP Link glasses for this, not the IR Glasses. You can find them for $45 and up all over the place (Ebay, Amazon, Ultimate 3D Heaven, 3DTV Corp, etc.).

However, the GT750 also comes with an RF emitter, for use with RF Glasses, which are sold separately. RF glasses range from $79 up to $129, depending on the brand. There are 3 brands (Optoma, Monster and 3D VIP) but they're all just re-badged units from a company called Bit Cauldron. These RF glasses have several advantages over DLP Link and Infra Red glasses; The lenses are not as dark as those other glasses and you do not need line of sight in order for the glasses to receive the signal. Unfortunately, they cost more than the other glasses, so it all depends on what you're willing to spend and what you're willing to accept. DLP Link and IR Glasses are not bad, but it looks like the projector market is trying to move away from those two older technologies and go with RF and or Bluetooth.

I have Optoma HD3300 and Onkyo 809. They work very well together in 3D.

I will post more pictures later today. The images I recently posted are taken from satellite tv( in the uk) not blu ray images. I'm yet to buy a blu ray player but hope to get one in the next few weeks.

the reason you can see screen door is due to massive image size and 720p resolution.

i can see screen door on my 1080p if i'm sitting about 1ft away, but i'm never that close. there are great advantages of 1080p even if you only deal with 720p content.

I had a GT720 for a while but returned it, not so much for the 720P but the 3d problems which is too long a story to post about here especially since I posted about it in that thread. You can see a screen door on any PJ if you get close enough. I sat far enough away from the GT720 it was never an issue. I also noted that it seemed like the GT720 was just not as sharp as I thought it should be despite never having had a PJ before. My 8350 confirmed that as there is no comparison, (in my application, 120" screen) between 720p and 1080p. Now while I am impressed with my 8350, I can say that there is a definite diff between DLP and LCD.

What is my point? I was going to get the GT750 when it came out for 3d and use the 8350 for 2d. Well these secretive manufacturers came out with affordable 1080 3d units right after I bought my 8350 so I am second guessing myself. I could live with the GT750 for 3d viewing and quite frankly most material was fine for 2d viewing at the distances I view from. So yes, 720p on a 120" screen looks better than any 50" give or take TV because bigger is truly better here unless the PJ stinks.

So for the money the GT750 should be a fine unit for entry level and it has on board speakers and portability. I would probably have just kept the GT720 were it not for the Nvidia 3d issues and I called BS on that after spending what I did on my HTPC and Nvidia card and there they were again with their hand out. I mean I already had 3d on my DLP TV and I knew HDMI 1.4 was around the corner.

Let's be brutally honest here, look at your needs and viewing habits. Gaming is not going to be 1080p in most cases. Depending on your carrier, in some cases the best you can do is 1080i and that, in a lot of cases is upscaled in the cable box from 720p which ESPN and some others use. While some boxes do better than others, making 1080i from 720p sources yields a 720p picture because you cannot make what is not there, well, with the exception of frame interpolation but that does not change the pixel rate. Got it? You cannot add pixels that were never there. FI simply attempts to smooth things out by averaging.

I just wonder if the Optoma simply incorperated the 3DXL tech into the GT720 and called it a GT750. Seems that is the case and that would make the GT750 the current 3d high def PJ value leader right now. With it's short throw and bright picture, just put it on a table in front of you. It can make up to a 300" picture. Now Acer said they were going to do it months ago and released their unit in Europe but it never made it here. I wonder what they are doing now and why that 5360BD never made it here?

there's definitely a difference, but 120" 720p and 120" 1080p is a huge difference too. maybe some PJs are better than others at detail resolution and ISF doesn't have resolution as it's #1 or 2 thing it cares about during calibration..but the bigger you go, the closer you sit - the more you would appreciate 1080p.

taking into consideration the pics are taken during the day i think the gt750 does very well through satellite hd tv. In future i will ensure the mirror is not in the shot

post #293 of 619
for most its apples and oranges comparison here. yes, hd33 1080p is better projector, but it depends what you are watching, if you watch 1080p, then it will be better, but what is 1080p? bluray discs and I think directv if I understand. so if you don't have 1080p source, then its not really an issue.

then there is the issue of room size, the other projectors need quite a long throw, at least double for hd33 over gt750, so 135 inch screen is 7 feet for gt750 and 15-17 feet for hd33. further you get 25FL with gt750 and 15-17fl with hd33.
post #294 of 619
i found the throw calculator to be a little out with the gt750 i am projecting 120" image from 7 1/2 ft away. my room size required a short throw projector and from my viewing distance of around 14ft 720p on a 120" looks good to me
post #295 of 619
the gt750 has its place, in fact i will probably get one for my sister instead of buying a paltry 37" LCD TV for the same price.

but even though content is not 720p, 1080p will upconvert (gasp) and pixelization structure is not evident. but I would be very happy with the gt750s lumens for the price, IMO.

There isn't much 1080p other than blu ray disc available anything. Most are upconverted from 720p to 1080p, like video games and some cable. I think the whole 1080p thing is overblown. I watch my JVC with blu ray and 3d blu ray disc. So, it about 8-10 hours of month compared to 100+ hours of tv, pc, ps3, dvds, sports, and downloads that are not 1080p. I sold my JVC for the new models last month and it hasn't affected my viewing at all. Blu rays still look good on my GT720 and ML500. So, if you are not going to make a big investment in a good screen, a projector with great blacks like a JVC or sony, and making your viewing theater friendly, I think a 720p is a excellent choice.
post #297 of 619
if you look at it side by side, you can see the difference, if you don't have it, you won't know the difference, i was watching sd on a 60 inch old tv that my brother in law gave me, i wouldn't be watching hd now if it didn't die and i was happy with that tv.
post #298 of 619
hi all, i am new to projectors so apologies for asking this question here.

I am looking at the gt750 because i like the idea of the 3d, cheap and short throw aspect.

Is the gt750 a good projector to start with? Is the 3D good (compared to say a plasma tv) and would a 84" projector screen on a tripod be good to use with this?

Reason being is that the mrs doesn't want the kids to watch large screen tv so instead of hanging a projector screen i have been given the ok as long as the screen could be put down and moved away each night after watching.

because of the shape of the room i need a short throw since there would only be about 6 foot from the projector to the screen.

tia for any help/recommendations.

you could hang a rollup screen, an electric one and just roll it up.

If the wall is flat and untextured, you might just use one of the paint options. Then there is no concern of raising or lowering the screen. There are lots of good threads on this forumn and others regarding DIY screens using paint, as well as laminates, fabrics, etc....

Lower end projectors are incapable of reaching the blacks that a Plasma can achieve.
