glasses arrive on friday, i'm hoping it'll be fine.

Are you using sky hd for the football I had lines in slow motion shots, make sure your hd box is set to 720p

[delf]

I'm using Tivo and its set to 1080i, i'll try changing it now. thanks for that.

its the sd pictures i'm really struggling with, get lines through any panning shots. using hdmi 1.3 at the moment, 1.4 cable arrives tomorrow.

[delf]

720p setting makes a big difference. not sure why i didn't do that in the first place. thanks jason.

[aoaaron]

need... 1080p version...

[kbfern]

There ain't one.

The gt750 is my 1st projector and overall for what I use it for I'm very satisfied. I'm very limited to my throw distance hence why I bought it would look into upgrading maybe in 12 months or so as thinking of moving property however if I can't accommodate my home cinema then it's a no go ha ha

Hello Owners,

I demoed some projectors the other day and now know that I am susceptible to the rainbow effect, so much so that I left with a bit of a headache. The ones I saw it on were the HD600x, which wasn't too bad, and then either the HD20 or HD23, on which I found the rainbows to be quite a bit stronger. I also demoed another brand, which after some tinkering the rainbow effect was much reduced and less of an issue.

They didn't have the GT750 so I couldn't check, and I'm struggling to find anywhere with demo samples in stock (I don't really want to order and have to go though the effort of returning it if unhappy).

However, I've only seen two comments about rainbows in this thread, and from memory I don't think they were particularly dire, so I'm hoping it's not too much of an issue.

Anyone care to comment on the presence and strength of rainbows on the GT750? I accept that they probably do occur to some degree, and that's fine as long and it's not too strong, but does anyone who is normally bothered by rainbows consider them to be an issue on the GT750? Has anyone noticed it but then been able to reduce them by adjusting the picture settings somehow?

I'm pretty set on the 750, due to throw distance etc, it's just this last stumbling block i need to confirm before jumping in.

Cheers

The 750 may be worse to your eyes as it is much brighter than the others you have seen already.The brighter the DLP projector the worse the rainbows I am surprised if you found the HD20 worse than the 600x or HD23 as again these are brighter than the HD20 but still not as bright as the GT750.

The other things that effect rainbows is the speed of the colour wheel and the colours of the segments in the wheel. The faster the wheel the less rainbows is usually the case.I did see a Acer 5360bd a week or so ago and found this has a setting in the menu for a grey screen and with this switched on saw no rainbows at all.

However this pj does not have as short a throw as the gt750, I think if you want a huge screen from 5-7ft throw the GT750 is your only choice but you may be plagued by rainbows.Just one point rainbows do sometimes get less as you watch over a period of time (10-20hrs+) but that is not the case for everyone.

[Fossal]

I have about 200hrs on my GT750, at first I did notice rainbows a lot but now only when I see subtitles or look away and look back at the screen quickly are they noticeable, for me and the Mrs this is more than acceptable. This is my first projector so not as experienced as others, but have no regrets in buying this PJ.

I hope next year they make a 1080p model as I would upgrade.

[camalot]

I have bought the GT750 and have seen other PJ have bad rainbows.

However, i don't actually notice much with the 750 on ecco mode. If you go looking for them and whiz your eyes across the screen really fast then i do notice them very slightly just out of view of my eyes, if that makes sense.

Certainly don't notice anything watching a movie normally.

Received mine on Friday, 6-7 hours of "Testing" with various sources and then Transformers 3 in 3D.

A few points:

- I have a Samsung PS51D6900 51" 3D TV, 3D details is excellent but can be dark, wanted size and brightness for 3D.

- I demo'd 720p (HD600X) vs 1080p (HD23) in Richer Sounds and decided given I needed short throw, this was the best option. Yes you get a bit more detail but for 3D 1080p with glasses, was working out twice the amount, plus mount etc.

- SKY HD is best viewed with the SKY box set at 720p, I noticed the same line effect when viewing in 1080i as another poster. Line effect not noticed in any other resolution input, 1080p/60hz and 1080p/24fps both fine.

- 1080p/24fps gives the best picture on this projector. Smooth and natural motion, detail levels are excellent and blacks are perfectly respectable after some tweaking of settings.

- In two days, rainbow effect only noticed once in some scenes on a downloaded HD copy of MI4: Ghost Protocol, other than that no rainbow effect encountered on any other source.

- No need to run the projector in BRIGHT mode, STD is the best for both 2D and 3D, unless viewing with loads of ambient light. Dark room viewing STD is perfect and the projector is very quiet.

- I am getting an 80" image from only about 5ft away from the screen. Purchased a portable 80" Optoma Widescreen, sets up within 30 seconds.

- I have the DLP Link glasses, QED Performance 5M 1.4 HDMI cable running from my amp, I get little or no crosstalk and the 3D picture is simply awesome. Tested disks Megamind 3D and Transformers 3 in 3D.

Overall a great value projector and for me it works great for movies, just have a play around with the settings. I'd recommend it for 550-600 quid, you cant go wrong.

[AFM1]

Thanks for your review, Santo, very helpful, and also thanks to all the other recent posters, all of which have helped me along my search. I ordered a GT750 last night, with the 3D-RF kit, so have now joined the owners list, and hope to set it all up this week when my screen arrives - very exciting...

Cheers

Kbfern, in my previous post I think it was the HD600 and the HD23 that I was looking at in the demo, not the HD20. As to which of them I noticed RBE on more, I can't say I am 100% certain which way round it was now (but I thought it was less obvious on the 600). Also, I was intentionally spinning my eyes round quite a bit to see them as it was the first time I had been aware of them, rather than just watching like you would normally, so it wasn't really a fair representation of normal viewing, and it would explain why I left with a headache(!)

This pretty much echoes my experience with the GT750 and rainbows.

[BlinneOrlaith]

How’s she going guys? I am pretty much decided on the GT750XL, any good deals at the minute? Where did you order from?

[AFM1]

My GT750 arrived yesterday and I had great fun projecting a 4m wide 183" 16:9 image from 2.8m distance last night. When set up properly I'll probably stick to 120", but it was fun to get it so big. Personally I think that's the beauty of the 750, with the 0.72 throw ratio you get the freedom to project a sensible sized image for regular viewing but you can also go huge when you fancy it just by moving it back a bit.

The good news is that even when watching this huge image from just 3m I notied no rainbows at all. EDIT: they are there if I look for them, but they don't jump out at me in regular viewing.

Anyway, on to the reason for my post:

I was going to get a grey screen but held off and bought two blackout blinds instead, one white and one grey, just as a rudimentry side by side trial of white and grey to help decide which I prefer before ordering a real screen. Obviously I have no idea what the gain would be on either of these, or how the shade of grey on the blind would compare to the shade of grey on a 0.8 gain grey screen (although I'd say it was a fairly medium grey). The blacks, colour saturation and detail were all noticeably better on the grey one, as expected, but whites became noticeably grey and some light faces became darker (although they seemed to be more detailed). This is also to be expected to some degree, and perhaps the shade of grey was too dark, but in general, can the greyness of the whites on a grey screen be eliminated / reduced via adjustments to the image settings (brightness / contrast etc) whilst still maintaing the benefits to the blacks and colour saturation, essentially striving for the best of both worlds (within the confines of the projector itself - am not expecting miracles).

Or is this all because the blind is too grey? Would it be less obvious on a proper (light) grey screen?

I haven't made any changes yet, all settings were on default, with eco and using the cinema mode.

Also, how would using an ND2 filter compare to using a grey screen, with regards to the above?

Cheers

AFM1,
If you don’t mind me asking, where did you order from? The best deal I can see for the XL at the minute is the is at Curry’s for £600. Maybe get 3% quidco or whatever it is now.

I got mine (not the xl) from Amazon for 547, plus 8 quid for delivery. I did want to get it from an independent shop, but I had to be confident of a return policy just in case, so went with Amazon.

Then i got the 3D-RF kit with 1 pair of glasses for 70 quid, so only about 30 quid more than the package with the DLP glasses (prob no major differences between the two systems, but that's what I decided to go for). I'll need another set of glasses at some point, and they do they seem to be more expensive at 60 quid minimum, especially as the non-Optoma DLP glasses are available for 30 quid ish.

£600 from currys/pc world is what I had found for the XL also, though they don't seem to have any stock for in-store collection, just delivery only.

[kh4tri]

will the optoma zd201 glassess work straihgt away, do you need an adapter etc, rf kit
eg, had the 3d-xl box previously and still got 1 pair of glasses, can i just use those without buying an additional kit

[hessian]

You don't need anything extra

[AFM1]

Tried out the 3D-RF glasses last night and I could hear a loud buzzing from the left arm near the 'on' button - has anyone experienced this? I assume it's a fault and not just standard operational noise. If this is normal then they'll definitely be going back, but if not then I'll get them replaced.

Also, is there a recommended screen size : seating distance ratio for when watching 3D? I skipped through Underworld Awakening in 3D and it was pretty awful to watch as the glasses didn't always turn the fuzzy image into a cohesive 3D image - most of the time it still looked fuzzy through the glasses - particularly noticeable with text on the screen and menus being unreadable.

I don't know if this is due to sitting too close to a large image, or if it's related to the buzz in the glasses. There were some moments when you could sense things were working, a bit, so the glasses are not completely broken, although I guess they may not be syncing correctly. I started with a 120" image, sitting about 2.8m away, but also then reduced it to about an 80" image and it did seem to improve it a bit, but not completely.

Another thing which I guess could be quite significant, is that I was projecting onto a dappled/mottled lemon-yellow coloured wall as I haven't got everything sorted in the room it will be going in . Could that have interrupted the presentation of the 3D image? I've seen some screens being advertised as "3D ready" or "3D compatible", and I assumed that this was just marketing speak, but is it actually true that you need a particular type of screen for 3D???


As a background, the source was an Oppo BDP-95, with all 3D options enabled, and using a 5m QED performance graphite 1.4 HDMI cable, direct from the Oppo to the GT750. The 3D-RF emitter was plugged in and the lights lit up green. 3D in the GT750 settings was enabled and all on auto I think, with the image displayed as frame sequential (not SBS or top and bottom).

I have two pairs of rf glasses and neither buzz.. Unless im feeling lazy and try to lye on my side then I hear a buzz in my left ear as the arm of the glasses slightly bends. Strange how ur image is not clear, iv watched a few 3d movies so far, tintin being most enjoyable and impressive on the 750.. If the green lights on the emitter are solid then its locked on definitely. I would assume faulty glasses in this instance.. Get them exchanged..id want them tested first by retailer or swap them out for the normal ones which can be bought a lot cheaper

Im just using a standard pj screen hence I doubt that being a problem.. Can you just test the pj on another wall? Ideally flat and whitish..

[delf]

Does anyone else notice that there seems to be plenty of depth to the pictures but lack of pop out effect, or is this just due to me watching films converted to 3D and not filmed in 3D.

Don't get me wrong, I watched Cars 2 with my kids this evening and the picture was brilliant, lots of depth and detail, but not where you feel like you can reach out to touch the image. I've got transformers dark of the moon here but haven't watched it yet, i've read that a good 30% of the movie was filmed in 3D, can anyone recommend a good scene to test it with, as i've seen the movie before and thought it was a bit rubbish lol.

Maybe i'm expecting too much from a budget projector, still worth every penny though. Black ops in 3D is an experience, especially when your aiming down the sight.

[jasonleechapman]

There is a lg 3d demo clip you can download I don't have the link sorry but I'm sure someone else on the forum will know it. It shows various things from a computer generated clip and especially a underwater scene where a fish seems to come right out of the screen. It's the best pop out I've seen on my gt750

[cpmarvin]

I've recently bought the Optoma Gt750E projector. I'm getting a lot of lag(around 100ms comparing with laptop and asus tablet, need to find a crt) when using this projector with my favourite game using ps3. The main reason for buying this projector was a lag free display.

Any recomandation if i can improve the lag using the projector menu , maybe i have a wrong setting , because every review i've read idicates a 0 lag for this projector. A side not , the game is not running in 3d mode.

Thx,

Marvin

[bazonix]

Hi set the ps3 to output 720p. Hope that helps

[AFM1]

Quick poll if you don't mind, as I am having trouble deciding between the two options?

In a normal living room environment, how many GT750 owners are using a white screen and how many are using a grey screen?

Did most people just go with a standard white, or are many people going with grey? What are your thoughts?

I have tried both white and grey, but not on proper screens, hence my indecision. I like the blacks and colour contrast that the grey screen seems to give, but not sure if I can live with trade-off with the slight greying of on the whites that I saw on my temporary white/grey side by side trial .

What do you guys think?

[nolia]

Anyone knows the link to the LG 3D video? I got my GT750 on Saturday from Curry's Reading. So far so good. I am also looking for another pair of glasses for the boss.

[rde]

Would this be a good projector for a DIY multitouch projector table considering its short throw ?
Maybe in combination with a mirror ? Or would that deform the projected image ?

[dazzzler]

Hi All,

Have been lurking for a while, always good info, and i'm now about to take the plunge and buy a GT750. The only thing that worries me about it is the fact that there's no zoom, and i want to ceiling mount it, so placement will be critical. Does anyone have any recommendations for mounts, or can you put my mind to rest that setting it up is a piece of cake? I've seen a couple of mounts on ebay, which look like clones of the optoma one, and appear to have some horizontal adjustment, what do you think?

I'm also interested in the answers to the grey/white screen debate, its going in a garage conversion, so the screen will be "only" 92 inches at the opposite end of the room from the window, and i am going to be fitting blackout blinds, so any thoughts on this would also be welcome.

Look forward to reading the replies...
