umm I looked in there did not see a display type?? I looked here: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\NVIDIA Corporation\Global\Stereo3D

I just looked again and seen Stereo monitor ID is that is if so here it is: 0x00278d3e(2592062)

Sorry, it's been a long time since I had looked in there, I should have looked before asking. I think it's Stereo Viewer Type or Stereo Type Set. Perhaps you could just screenshot and post the Stereo3D registry entries. I'm thinking that blue-ray 3D has it's own entry, if so, perhaps a better bat could be made that sets the entry and locks the registry to avoid reverting until gaming is finished, even if 3DTV Play is enabled at the time.

Could this work with DSR?

@Dazzle233, Yes the DSR Factors are there in my NVCP so it should work.. @D-Man11 here are the screenshots you requested..

Thanks for the registry pics, it will be awhile, but I'll get one of my TVs from upstairs and hook it up to check my registry settings using 3DTV Play.

So, I'm still trying to wrap my head around this... [quote="D-Man11"]The guy that made the hack said "-Wital- ... allow limited HD3D 1080p24(Blu-Ray DVD [color="orange"]full frame SBS 3D[/color]) output setting in control panel but driver can output 1080p120(HDMI 1.4a limit)[color="orange"] Stereo3D for passive TV/monitor[/color]."[/quote]If I were to create a custom EDID resolution/referesh, and mock it as a passive display, would this somehow allow me to get Full SBS frames (or TAB)? I found an image for the frame-packed format after a quick search: [img]http://i181.photobucket.com/albums/x66/LeeAStewart/Blu-ray-3D-signal420.jpg[/img] If I could get game output in this format for a desktop capture (or a similar Full-SBS layout), it shouldn't be a problem to capture the image for display in VR. Could this hack allow something like this?

Ummm...no idea, perhaps try it?? Read the Reddit?? Download the zip, look at the options?? Keep the comment by Pauldusler in post#8 in mind

Yep, I'm workin on it, I'm just not familiar enough with the formats the driver is capable of putting out... Was wondering if someone else already knew. I poked around at full frames a while back, but didn't have much luck. I'd always get stuck at the same point. This is a different approach though, and made me think of a few ways it 'might' work, but we'll see. Thanks for sharing.

Tried this with a 1080p acer h6518bd projector with dlp link glasses and it worked somehow but i get 60 half Hz in 3d, is this right?

What's the max pixel clock on your PJ? That sounds right if it's 175MHz and full frames are being sent. 1920x1080P@60Hz 2D is 172.7981Mhz. If you were to make a custom resolution using "CVT reduced blank", you can get 72Hz (172.2365MHz) The other option is to send Half Frames, if your projector supports and if Nvidia will output it with this guys bat files. Another way is to reduce 1920x1080 to a smaller 16:9 number, Joker18 had a post on this somewhere. 1920 divided by 16 = 120 1080 divided by 9 = 120 So times 16 and then 9 by 100 and use those values perhaps. It wouldn't be 1 to 1 pixel mapping, but should still work well.

Thank you D-Man11, but i don't know as much as you, maybe it is a bit too complicated for me. i think i stick playing at 720p, downsampling from higher resolutions with edid override and reg tweak as long as possible, it looks great. aw edid editor reports a pixel clock of 148.50 could it be possible to get a higher refreshrate than 60Hz at 1080p for 2d with a custom resolution, you talked about reduced blanking and 72Hz. i also played around with 3dmigoto side-by-side for dx11, it worked but i was not able to downsample, is this possible? thanks again, great community

You can use monitor asset manager (free) from EnTech Taiwan and use the save "report" function to see the specifics of the displays EDID.

Ok, I just took a crack at this with my 1080P BenQ HT1075 projector (which in my previous years of testing I've determined has a 175Mhz pixel clock limit), and haven't had much luck. The instructions in the link are pretty badly explained, which doesn't help. Like, for the active output instructions, he just does this massive wall of text in step 3 (rather than breaking it down into further steps like he should have), and I'm not certain which of those are actually required or not. Like when he says to set the monitor refresh rate to 24 hz, is that a required step, and if so is that done while the game is still running or what? Jeez. I've successfully done up to the part where he says to minimize the game and run the sequential.bat, and when I go back to the game it does show 2 images alternating sequentially on the screen, but I can't get either my projector's glasses or the 3DVision glasses working at this point. I followed nephilim's steps: DDU'd old driver, unplugged my emitter, installed 416.94 driver, then enabled 3D in driver, which made me go through the wizard. When I was done I could see the HDMI Blu-ray 3D as the stereo display type. My questions at this point is: are we supposed to keep the emitter unplugged and use my projector's glasses? Or is there any way to use the emitter and 3DVision glasses? If I plug my emitter in at this point, the HDMI Blu-ray 3D option becomes replaced with the 3DPlay TV and HDMI Checkerboard options, however my Nvidia glasses don't activate at all when I'm running 3DPlay TV. (Side note: only way I've ever gotten my Nvidia glasses working with my projector is via the Acer 5360 EDID at 720P@120hz, which then lets me select the frame sequential 3D mode from my projector) I'm afraid if this requires use of my projector's glasses then I'm almost certainly out of luck. Based on the countless hours I've wasted trying to get Joker's EDID and custom resolution working in the past (not to mention my own tests with the Acer 5360 EDID and various custom resolutions), I strongly suspect my projector has some strong restrictions in it's firmware. For one, it's glasses only activate when I can select a 3D mode from the projector's OSD, but the projector will grey out most 3D options (namely frame sequential and frame packing, it'll always give me SBS/TAB options) unless it's being fed one of the standard 3D modes (720P@120hz FS, or 720P@60hz/1080P@24hz FP), it's like it needs the Nvidia driver to tell it that it's ok to allow for 3D, which obviously these hacks and workarounds are trying to get around. I guess, lastly, I'd just like to clarify what this whole thing is achieving: is this achieving a full 1080P image @60hz via frame packing (so 60 fps/hz per eye), or is this doing 1080P@60hz frame sequential (so 30 fps/hz per eye)?

Yes you are supposed to keep the emitter unplugged and use your displays glasses. I believe if is FS at 60HZ so 30FPS ingame but it is at 1080P and 60HZ unlike the 12.5 FPS we would get at 24hz.. the FPS are a little better and some games it may be ok but for DCS it was a little laggy like.. but I think Elite Dangerous was not too bad..
