Sorry, nVidia does not offer custom timings under Vista. I did not have any chace of making it work so far. But I will keep trying. Maybe with tweaked inf files or external EIDs. I got 50Hz once when I hooked my Vista laptop up to my Sony LCD television. But I was never able to force it like under XP.

hi krix
thx for answer :-)
it the same old problem......its no problem to get 50hz (if i connect a monitor with this edid) bur if i have 50hz on the output the render window will not initialize....so you see only the desktop background.
i try to download an old driver (100.30) which shoud support the advanced timings tab but i get noe picture with this driver :-(

this is somthing i found on the nvidia page:
http://www.nvidia.com/object/advanced_timings.html
and my meaning:
i think it is a bug of ventuz because this is the only software i know (and i work with some different presentation software openGL and directX based such watchout, mxwendler, screenav, wings) which has this problem.

now i am shure....this must be a bug,
in the past ventuz told that his problem only occours if you connect via dvi but i also have the problem via analog vga. i have a desktop running on 50hz with my 8800 gtx but i get no render window. this is a big problem for me because i have a presentation in 2 days!!!!

But you are only talking about Vista now, right? Under XP we got everything working at 50Hz in "that" other threat. If at all possible, go with XP. But I guess, because of the "core2 problem" you mentioned in the other thread, you cannot. Or why would you use Vista?

I am working under Vista because I really like the new UI. But I always thought the performance was not as good as under XP. That's why I am still running the Presenter on XP machines. The movie playback seemed better though out of the box. I played back three PAL clips and had a live video from a webcam all at the same time at full HD. If Vista solves all your problems, then I guess we "just" have to figure out how to get the 50Hz working under Vista. And as before I am quite sure that it has nothing to do with Ventuz nut with how the display is configured/installed. :) I downloaded PowerStrip (supports Vista now) and will play around a little bit.

Did you ever try hooking up your machine via Component video and let Vista treat the output as a HDTV video signal?

hi krix,
does powerstrip support the nvidia cards?? last drivers didn't because of the advanced timing of the nvidia driver.
component? no never tried also because i cand use it in this situation.
what i dont understand (again) is that 50hz is working just no render window. do you try to adjust power strip??
for me i think vista is better because: no cpu problem, better antialiasing. 3 pal videos is realy no problem but live input is still impossible to us. i measure 5 frames delay (but now constant)
usb problem is solved, i had to reformat the stick (there is a hp tool in the web) in copy the license back
thanks for your help

Yep, PowerStrip does not allowtweaking any advanced timings. But i wanted to mess around with the monitor infs and registry settings. I also messed up the nVidia graphics card driver but no luck. According to a couple of Forums and Websites, Vista is focusing much more on Device EDIDs and as long as nVidia does no offer custom timings, I don't think it will be possible.
I take it the Renderer is visible in Virtual Fullscreen mode but only when you switch to exclusive fullscreen mode do you have the problem. Are you running one or two monitors? If you are using DualHead, then turn that off and directly hook up the 50Hz device (an Encore??) as the first monitor. Try to let Vista take care of the rest. If you are already doing that and still cannot run in Exlusive Fullscreen, then the resolution/refresh rate are not a proper supported setting. The resolution and refresh rate have to be available as a standard resolution from Windows without having to deactive the "Hide modes that this monitor cannot display" setting of the monitor. Only then can DirectX and Ventuz initialize a proper exclusive Fullscreen rendering. Windows does not report the other resolutions to DirectX. Under XP we tricked Windows and DIrectX by overriding the refresh rate from within the nVIdia graphics card driver. Windows and DIrectX believed they were rendering 60Hz when in fact the graphics card was rendering 50Hz. Worked beautifully but sadlythat feature does not exist in the Vista drivers. So first step would be to make sure that the resolution and refresh rate of 50Hz are treated like a standard resolution in Windows. If other programs based on DirectX9 (OpenGL does not count!) do work under there conditions and Ventuz does not, then there might be a bug in Ventuz. But I really doubt it.
Here's hoping that it is something else ...

BTW, the nViia Vista drivers have another serious drawback - no horizontal or vertical span modes.

At least now I can reproduce the behaviour with the Render Window disappearing. I was successful in modifying the nVidia inf and now can select 50Hz as a refresh rate. But the refresh rate is not available as a standard resolution. I can switch the desktop to 50Hz now, but thats that. I tested a couple of DirectX Fullscreen applications such as Benchmarks but they all switch to 60Hz automatically. I am running out of ideas here...

hi krix, first thx for your help :-)
on xp i tried screenav (a german alternativ to watchout) with 50hz and no special nvidia tweaks so that windows reports 50hz. no problem to switch to fullscreen. and the output stays on 50hz. ventuz please download the demo and try. why? maybe you agree that it is a bug. i wouldnt care about it if i would find a way to play 50hz on vista
