Is it possible to have both 1920x1080@24Hz 2D resolution AND 1920x1080@24Hz 3D NVIDIA

Thread Starter 
I would like to run my Windows desktop at 2D. However, once I add 3D capabilities to Windows using Nvidia (which creates 1920x1080@24Hz and 1280x720@60 3D resolutions). However, when this happens, my 1920x1080@24Hz option is no longer available in 2D.

If I try to create a separate 2D 1920x1080@24Hz custom resolution, Nvidia will say that I already have this PC resolution.

Anyone with an modern Nvidia card and has messed with 24Hz and has 3D capabilities on their TV would most likely know what I'm talking about:

Uncheck the box for stereoscopic 3d?

Thanks, but if I uncheck that option, then my bluray player "TMT" wont be able to enable that setting automatically when it needs to play 3D. It expects for stereoscopic 3D to be enabled. I really dont want to have to manually toggle that option each time I switch between 2D and 3D. I was hoping for a dedicated 1920x1080p@24Hz 2D resolution and a dedicated 1920x1080p@24Hz 3D; which would also be compatible with resolution changer and autorefresh rate changing apps.

So do people currently manually check and uncheck this option every time they switch between 2D 24Hz and 3D 24Hz? Surely there's a more automated way..

I have no problems with 24hz 1080p. It automatically goes into 3d mode when playing a game in 720p@60hz or a 3d bluray in 1080p@24hz, theres no need to manually switch. Im able to choose 24hz for 2D from the refresh rate drop down menu you showed along with a lot of other refresh rates like 23hz.

Can you please put up a screen shot just like mine? Id like to see if you have a 1920x1080@24Hz entry under the HD section as well as under the 3D section. As far as I know, it's not possible to have the same exact resolution and refresh rate occur more than once; even if it's under a different section.

Thanks!

I had to make a "TMT 5 3D" batch file that enables 3D when starting TMT and turning it off when closing it. I have a separate icon for 2D movies.

Can you explain how you made this?

Hi all,

I have exactly the same problem.

This is really annoying since I have more 2D movies at 24Hz then 3D movies.

I am using driver 280 and have a GT520 Card connected with HDMI 4.1 to my Samsung 59D8000 Plasma TV.

Can someone tell me how to fix this?

The 24p 3D mode in 2D works but the picture quality is really bad compared to the normal one.

Btw, I am still using the 280 driver because all newer drivers have problem with the HDMI sound (DTS is stuttering) and couldn't find any solution online why this is happening. I am using the Denon 1912 receiver.

As you can see from the first picture, there is no more 24Hz option ;(

Thanks for your help.

Don't you need to set up 23/24Hz in the 3D menu of the player ? It's been a while since I fiddled with nVidia stuff but this should be across the board with any 3D capable card.

Thanks for your message.

Yes this is HDMI 1.4 but after this the 1920x1080@24Hz option is no longer available in 2D.

I am using PowerDVD 12 and it needs to have the stereoscope 3D activated.

@TS, can you perhaps help me out?

Can you manually adjust it in windows, there should be a 24Hz setting there.

In windows desktop r click screen resolutions--->advanced---> monitor tab in the drop menu there should be a list of refresh rates.

Ahh... I remember now when I had my GT 220 I had to manually disable 3d in the nVidia control panel to get 2d 23Hz, it's the one Achilles heal of nVidia's 3D implementation. With my ATi setup there is no user input everything just works, but then again I always have my HTPC set to 23Hz. VLC takes care of my NTSC recordings just fine without switching refresh rates.

Hmm, that is exactly what I mean.

So you reckon it will work with ATI?

Still hoping for a NVIDIA solution............

Hmm, perhaps I can try 23hz instead of 24hz?

You reckon 23Hz is as good as 24Hz? Most movies are 23.96Hz........

3D 24Hz simply gets overwritten even when i tried to set 23Hz and put it on 23.976...

I have long stayed away from ATI and promised myself never to go back...

Hope NVIDIA gets this sorted out sooner than later...

Ok, this is tempting me to give ATI a chance again...

Which ATI GPU are you using to have this working properly?

Might be time to shift camp... biggrin.gif

I'm using an ATi HD 6850 256 bit card Cat 11.5's, I run simulations on this rig also so 256 bit's is very important. But any 128 bit 6xxx card should work just fine for movies.

My main movie rig:

Lian Li PC-60/65? Blk Tower (I forget it's pretty old)
HD Plex IR receiver set up for S5 for my Logitech 720 remote.
W7 x64 No Windows updates, No UAC, No Front End no Tuner no Anti virus
Intel i5 750 1156 @ 4Gigs do a lot of encoding on this rig while I watch movies.
Gigabyte P55 UD-3 (rev-1)
8 Gigs Ram
Raptor 75 Gig HDD main OS W7
Back up drive WD Black 500Gig main OS W7
LG Super Multi Blu HD DVD combo drive
Pioneer Blu Ray burner
6TB’s storage no raid.
ATi HD 6850 Cat Drivers 11.5 (Diamond single slot)
Cooler Master 650 Watt PSU

Running one HDMI cable and one Display port to HDMI through Pioneer SC-7 to Panasonic VT-25 Plasma 3D TV @ 23Hz extended.

The HD6850 looks quite pricey for non gaming HTPC...

It's definitely overkill if your not gaming, as I mentioned any 6xxx card will work just fine for 3D/2D playback. Why not a 6450 like this one for 40.00.

Thanks but I think this card is soooo basic...

I currently have a GTX460 which took over from a HD5770 roughly two years ago when I upgraded my gear to support 3DBR...

After the upgrade, I couldn't help noticing the solid difference and the superiority of the GTX460 compared to the HD5770...

Replacing the GTX460 with a HD6450 isn't something I would attempt... biggrin.gif

I'd prefer to go for a more performant / power consuming mid-range ATI GPU, that is at least at par with the GTX460 quality-wise.

Anyone has recommendations?

Glad to hear it worked out for you and thanks for the progress update. Maybe post your specs and drivers to help other folks that were in the same boat as you. Pq is the first thing you notice ATi just has more pop with better detail. Then again they always had the edge when it comes to pq with better color accuracy. But ATi sucks for 3D gaming and nVidia still holds the crown on that one. If I run my simulator in 3D I have to run it through my nVidia card but the GT 220 just doesn't cut it for NR2003, so for the mean time I just run the one 6850 and play it in 2D. I may run a 4 series card beside my ATi card if I can find a single slot solution nVidia is just far superior for 3D gaming stuff..

If you guys are comfortable defining custom resolutions you could try the following:

1920x1080 24p 2D
1920x2205 24p 2D - Use this for 3D playback

Assuming this is for 3D Blu-ray playback; that content is put into 1920 x 2205 frames that your TV then extracts into frame sequential 3D.

Im curious how would real software Bluray Players like PowerDVD know how to automatically switch to that custom resolution?  AFAIK, real bluray players like PowerDVD just try to swtich to standard predefined 1920x1080p/24 or 1280x720p/60.  It wouldnt even know that the custom resolution exists.

 

I personally rather deal with this limitation than use an ATI based card..never liked navigating through Catalyst Control panel settings.  Nvidia is so much more straightforward and intuitive, IMO.

 

I ended up just making a batch file that automatically switches to 3D mode and back when starting a 3D BD movie.

With that said I suppose it is *technically* possible for a HDMI 1.4a compliant display to accept sequential frames (i.e. allow PowerDVD or TMT to extract the images from the 1920x2205 container), but then the output would be 1920x1080 at 48fps (24 frames per eye).
