Interesting.. I'll check if my dongle supports that when I get it. All I know now is that it has the E-D logo on it.

Well, I don't think E-D supports "sync-double" but they should support "line-blanking" which is needed for interlaced mode.

It supports it, the options in the E-D Activator are: Interleaved, Over/Under, Page Flip.
That's the mode that I primarily use, and my dongle is quite old model (doesn't support any *colored*-line-coding).
A proper description of that mode can be found here.


You're not exactly right. The image quality is better than interlaced/interleaved, because there are no black rows between the picture-data rows (like there are with interlaced/interleaved mode), now the picture-data rows themselves are just thicker (double hight), and therefore, the image is brighter. Some artifacts caused by the image scaling done by the driver (iZ3D) could be visible though, unlike with interlaced/interleaved.

When you output at 1280x1024@60Hz, the monitor actually gets 1280x512@120Hz, so it's not the same resolution. But yes, as far as your PC can handle high resolutions in 3D (performance-wise), the monitor will not be the limit, the reason for this being that the limiting factor here is the vertical resolution*refreshrate, which in this case is low (actually it's half ). As I mentioned in another thread, I game at 1600x1200@75Hz (which is actually seen by the monitor as 1600x600@150Hz, my CRT has a limit of 160Hz vertical frequency). In theory I could go all the way up to 2048x1536@75Hz (the monitor will get 2048x768@150Hz), and I tried it - it works, but my current hardware can't keep up with that rez (3MP) in 3D.

Heh!

So what are the options to get at least 120hz , non squashed, interleaved , etc??

I want to build an IR emitter , together with a sync box, that drives the emitter directly off the VGA cable.

Iz3d can't show > 120hz ???

I saw iz3d has some smooth FPS toggle now, meaning no eyeflip occurs if VSYNC out of reach .

If I understand your question correctly, you ask about the options to get full-rez per eye shutter mode, is that correct? Well, with iZ3D it's only currently possible in the "120Hz 3D Devices" output, only on AMD/ATI 5000 and 6000 cards (this no eye-swapping mode), on other cards a different mode is engaged, which occasionally swaps views (because it doesn't use the ATI Quad Buffer), but it's still better than the old "simple shutter" output. I have no idea if it works with refreshrates different form 120Hz, you can ask the only user I know to have successfully used that mode with his CRT monitor - TheOracle over at the iZ3D forum, which I think also has an account on this forum.

Why would you need 200Hz btw? If it's for the Sony FW900 you mentioned - it also supports only up to 160Hz (specs). And even if it worked, you'd be limited by that 121kHz FBT/LOPT to resolutions up to 960x600, if not even lower, like 920x576 .

@Zerofool: Yes, now that I think about it you are correct.

Thx for your input, ill borrow a HD5850. 1280*800 would be enough for me, but I want it as it is, no scaling. Pretty sure it can do 160hz at 800p ???
I want no extra orbital resolutions.

You're (both) welcome .
That's interesting, but it appears that I'm spoiled and I can notice imperfections on even higher resolutions (even with AA), so I guess it's very individual thing, I guess that's one of the things that separate videophiles from the rest of the (normal) people .
Anyway, the simple math tells me that for 1280x800 you'll have to settle with only 144Hz, if not 140Hz (test it with PowerStrip), and I hope that your CRT doesn't get as blurry in high refreshrate modes, as mine does .
Refreshrate (in Hz) = horizontal frequency (that thing measured in kHz, but to do the math, we need to have identical units, in your case - 121000 Hz) / (vertical resolution*1.05) [short info].

Ah. Sounds like I won't bother but settle on that damn 1.5 msec of hold time per 120.

Getting a radeon would involve some slippery deal with my brother too, I'll pass .

Maybe it'd even sync up with 3d vision without the emitter hack, and this G92b SLI really works like a charm... (maybe because there are some 3d vision notebooks with g92b sli , rebadging can be fun, huh)

I got my glasses now. (christmas gift)



They appear to be working fine, I've already played some games with it. I even performed better with them on than usual without glasses. Dongle doesn't appear to accept BLC mode. Needs manual activation from E-D.exe.

There is one problem however, not really related to the glasses themselves. I'm running Windows 7, and my graphics card is Nvidia ION (9400) with the latest driers installed. However.. when I put up my old CRT (Compaq MV720 17") the highest refresh rate I could choose in any resolution including 800x600 was 85 Hz. I know for a fact it supports at least 100 Hz at 800x600, not sure if that includes 1024x768. I can't select it.

I also have a Samsung monitor externally connected to a netbook. It can do 120 Hz fine even at 1024x768 , but when I connect it to my computer.. locked at 85 Hz.

Not sure if it's related to
a) operating system (XP vs Windows 7)
b) drivers or
c) dvi-vga adapter in my computer compared to direct vga connection on the netbook output.

85 Hz is fine I guess. That's the lowest acceptable refreshrate I think. Anything below that gives too much flicker. Still, you want to take advantage of 100/120 Hz if you can.

EDIT: Disregard that. Just tried Over/Under mode and it works great! Will use that for games. But there is one problem.. Games that use a cursor (e.g strategy games like C&C Generals) the cursor is way off. There's no way of playing the game when I have to click the cursor half a screen above where I actually want to go.. Is there a way to fix this or do I have to play theses games in Interlace with lower refresh rate?

That's normal, there are obviously no such profiles in the monitor driver, you have to make custom modes, through PowerStrip for example.


Nope, there's no fix for that. iZ3D did enable a 3D cursor in this mode (visible in both views, now working properly) in addition to the incorrect one, but I think it doesn't works with all games. So yes, for such games you'll have to use interlaced, or try the normal 120Hz shutter mode (with Radeon 5/6xxx card).

Hm, I started having some problems recently.
Sometimes when I start certain games, with iZ3D on interlaced and ED Activator on the same, as soon as I start the game my CRT goes blank (out of range) I can hear the sound from the game and manage to quit blindly. I'm back at the desktop but still no picture..
Other times it's the opposite, desktop is fine and I start the game and it's fine.. but then I exit back to the desktop and the monitor goes out of range. I restart my computer (and at the POST/bootup process it's flickering like crazy even without glasses) once it reaches the login screen it goes out of range again.

Solution: Turn the computer off. Wait 15 seconds, then turn it back on again. No flicker and it won't go out of range at the login screen/desktop.

I don't understand how or why it would go out of range.. games run at the same resolution and refresh rate as the desktop and it's interlaced.. not like I'm doing over/under which would double the refresh..

I don't think it's related to iZ3D but either the dongle or the ED Activator. If I start games with iZ3D active but without the activator everything is fine.

I use 1600x1200@85Hz both on the desktop and in all games.
