HD 3D 50Hz problem
  1 / 2    
I have used 3D Vision for a long time but have only recently got a display that is capable of taking a 3dtv play type input signal. My display type is listed as HDMI 1.4 Blu-Ray 3D in the control panel.

System Spec :-

Windows 7 64 bit
Nvidia GT 240 video card
latest 1.45 drivers for 3D Vision

When I run 1920 x 1080p 24 Hz 3D the image is as expected.
When I run 1280 x 720p 60Hz 3D the image is as expected.
When I run 1280 x 720p 50Hz 3D the image is corrupted.

I effectively get an overlap at the top of the screen.

I get a band of overlap about 20% of the way down the screen.
Top 30% of the image overlaps the bottom 70% of the image, however only the bottom 60% of the image is visible.
This results in a 10% band (20% to 30%) not being displayed.

example image should be :-

0
1
2
3
4
5
6
7
8
9

In 1280 x 720p 50Hz 3D I get :-

0
1
3
4
5
6
7
8
9


Not easy to explain but pretty easy to see.


Is there anything in the driver I can adjust to fix this problem?

I am using a Lumagen Radiance XE+ 3D video processor. ([url="http://www.lumagen.com/testindex.php?module=radianceXE_details"]www.lumagen.com[/url])

It is recognised by the nvidia control panel as Dell Radiance.

Virtually any hdmi display device can be attached to the processor. In my case it is attached to a G90 projector.

I can get it to work well at 1280 x 720p 3D 60Hz and 1920 x 1080p 24Hz. The problem only occurs when I try 720P 3D @ 50Hz.

This system allows me to control shutter glasses delay and provides a useable 3d image using a 3dtv corp gen2 emitter and Nvidia glasses.

Hi

I really dont have a lot of details on your configuration. It sounds like you are building some sort of professional Quadro/workstation installation. Is that correct? I can certainly connect you with our Quadro team for assistance if you like.

I had a similar annoying problem, although, once selecting different 'Picture Sizes' (usually p.size on the TV remote) the screen went back to normal.

Andrew,

thanks for taking the time to answer.

The Radiance Video processor is the central hub for video processing in a home cinema system. IMHO it is currently the best video processor available. It is capable of driving any display that has an hdmi port. I have it attached to a Sony G90 CRT projector arguably the best projector ever made. Recently a number of CRT enthusiasts have become interested in updating the Radiance processor to support 3D on crt projectors. There are a handful of people trying to make this happen so that it can be opened up to all crt enthusiasts.

On the input side I currently have

Oppo BDP 93 3d bluray player which outputs 3D top/bottom frame packed 1920 x 1080p @ 24Hz
Sony PS3 games console which outputs 3d top/bottom frame packed 1280 x 720p @ 60Hz
SKY HD 3D Satellite receiver which ouputs 3D side by side 1920 x 1080i @ 50Hz
I also have my pc which has a Palit GT240 video card with hdmi output.

The pc has been running 3D Vision since it became available without issue. This particular issue is down to 3dtvplay only and even then only a problem when attempting to run at 50Hz . Field sequential modes work fine at 96Hz, 100Hz or 120Hz when sent directly to projector via analogue connections. This is specifically an hdmi connection issue.

The Radiance can take in a signal from any of these sources and convert it to frame sequential 3d format at 96Hz, 100Hz or 120Hz depending on source input.

The Radiance does all this and eventually will be able to greyscale and colour calibrate through 3D glasses to get near perfect images.

On the output of the Radiance I have an hdmi sync extractor (also made by Lumagen) which has a standard TTL Vesa 3D output. I can use this to drive virtually any emitter and 3D glasses. The Lumagen gives me delay timing control so I can reduce ghosting to virtually zero. I customise my porch video timings to reduce ghosting further. With this system I hoped to be able to play my pc games ghost free on a crt projector.

I can get the system to run fine with video card set to 3D 1280 x 720p @ 60Hz. However if I could run it at 50 Hz . I could reduce the video bandwidth required.

I know my equipment is not on the approved Nvidia list, but I am sure if I could get it working well you might get a few converts to 3dtv play.

Hi

Do me a favor and at least capture the EDID and send it to us. We can try to see what it actually is doing and if we can support it.

Instructions are here http://nvidia.custhelp.com/cgi-bin/nvidia.cfg/php/enduser/std_adp.php?p_faqid=2774

Andrew did you get anywhere with this ?

I have just bought a 450 card because nvidia support told me my 240 was not compatible with 3d vision.

I have the same problem 3d 24Hz works, 3d 60Hz works, 3d 50Hz broken.

Please help I just know I will get grief when I try to take the 450 back as it will not do what I need.

Oops! they said it was compatable with 3dVision but not compatable with 3DTVPlay.

I managed to hook the PC up to a Samsung 3dtv today and it handled HD 3D 1280 x 720p 50Hz frame packed just fine.

So it looks like an issue with the way the Radiance is handling a 50Hz 3D frame packed source. I'll get in touch with Lumagen to see if they can fix the issue at their end. I'll post back here when I get an update.
