[quote="Volnaiskra"]I'm curious about you guys who use projectors, because it sounds like it's the best form of 3D. But I've never really seen one in action and don't really know how it works. What I'm most interested in is not so much the technical side, but simply the logistical side - I'd like to get a better sense of what your layout and experience is like. For example: [quote="Volnaiskra"] -Do you play games in a study or in your lounge room? [/quote] I mounted mine on the ceiling in one of my bedrooms. I have full 5.1 sound and blacked out windows in there as well. You'd be surprised how little these can weigh and how much weight a 1/8-1/4" "molly" and other hardware can hold even when attached to drywall. (the mounting bracket took 4 "mollys" and @ 35LBS each the projector ain't going anywhere) [quote="Volnaiskra"] -Do you have a monitor hooked up as well? If so, do you just clone the monitor image, or does the projector need to have a separate picture for 3D to work? [/quote] Just the projector. [quote="Volnaiskra"] -Do you use mouse and keyboard, or only gamepad? [/quote] I keep a wired mouse plugged in for navigating Windows to my 3 game launchers, there's a wired keyboard handy and wireles KB/Mouse available but +98% of the time I use a 360 controller. [quote="Volnaiskra"] -Roughly how big is the projected screen area, and how far back do you sit? [/quote] I started with 77" when I had it in the living room projecting to an actual portable projector screen and when I moved it into the bedroom I started with almost wall-wall coverage (9' across) however shrank it down to a mere 100" because of final mounting point and brighter screen (and some room on both sides of the screen, because of the mount the top of the image was a fixed distance from the ceiling, limiting the width) It's a 9x9' bedroom so that places me 7-8' away from the screen. [quote="Volnaiskra"] -Do you use the projector exclusively? If so, even for regular computing? [/quote] The game computer and attached projector is used just for games. I have lots of other devices that I use for regular computing (along with a desktop setup in another bedroom/home office) [quote="Volnaiskra"] -Where is the projector attached? The ceiling? Or just on a side table? [/quote] Low profile ceiling mount. Because of the size of the room I went with a Benq 1080ST. There are some limitations to the "ST" which the long throw 1070 does not have - namely vertical screen shifting. (the 1080ST won't do it) [quote="Volnaiskra"] -Were there any other idiosyncracies or surprises to your gaming experience that you weren't expecting until you got a projector? [/quote] I was surprised how well 720P scaled that large. With both the projector and tower in a small room I sometimes use a fan to blow outside air into the room as both act like space heaters. An almost life sized Lara Croft is rather stunning on screen. The immersion is better than anything I've done before. Seat height is something I did not worry about playing on the plasma in the living room but I'm looking to get a higher seating chair or loveseat for the room. Finding long power cords was somewhat problematic, I ended up ordering one from Digi-Key. Home-Depot of all places had the best deal on 25' high speed HDMI cables. Mine has the earlier firmware so I'm stuck at 720P for games unless I drop to 24hz (yuck). I'd be interested in replacing+upgrading it with a model that has HDMI 2.0 or Displayport and Nvidia's new sync technology.

[quote="Volnaiskra"]What are DLP glasses? Do 3Dvision glasses qualify?[/quote] DLP glasses are LCD shutter glasses, but use a different control technology to 3d vision glasses, so are not compatible. 3d Vision glasses pick up an infrared signal from the emitter (pyramid) and use that signal to synchronise the left+right shuttering. DLP Link inserts a visible 'flash' into the image. The glasses directly pick up the flash and use that to control the shutter for each eye. The flash is normally just a blank white image, but can be other colours (red?) depending on the display manucfaturer. That's why DLP link has a reputation for washing out contrast. Most (if not all) of the new projectors are DLP Link 3d, so officially you'd need to use 3dtv play to run games in 3d and you'd need to buy DLP link glasses too.

[quote="sammy123"] Wait, w1070 doesnt work 1080p SBS or TB with tridef? Because i think tridef's 1080p(60hz) top bottom / SBS looks better on a 1080p projector, than 3dtv play 720p(60hz). [/quote]I believe it can do that but you have to upgrade the firmware, which supposedly isn't a simple process. I haven't really looked into doing that yet since I don't know which games I should be using tridef with.

[quote="rustyk"]That's why DLP link has a reputation for washing out contrast.[/quote] Just so people don't get the wrong idea, it's a misconception because the glasses block out the white or red flash. The image looks washed out without the glasses, but putting on the glasses fixes it. The only way it would reduce contrast with the glasses on is if you're using cheap glasses that don't completely block the flash, maybe or if your room has a lot of reflections (white walls). The important thing about DLP-link, in terms of picture quality, is to remember to turn it off when you want to view 2D content. Otherwise you'd have 2D with the DLP-link flash reducing contrast and no glasses to block it.

Yes, that's why I said reputation :-) I've tried both DLP link and 3d vision glasses on my projector and I've not noticed any difference at all to be honest, other than the colours looked ever so slightly better using the 3d vision glasses. It was such a tiny difference it could even have been imaginary, they look so close to each other in image quality. Even though professional review sites says the DLP link crushes contrast, I personally haven't found that to be the case at all. It's a really neat solution.
