Force TFT as Primary Display in dualview when TFT power is off.

funny · April 23rd, 2007, 10:37 AM

Hi,

since we have the TV Out Aspect Ratio Overlay bug in ForceWare Drivers i decided to use dualview mode with VMR so that my tv card application starts on the second screen (TV) with no black video window. (Primary Display is my TFT and second my TV with nothing on the desktop)

So if i turn on the pc with primary display is off windows decides to set the tv as primary. When i power on the TFT while windows is running there is no Picture. The full Desktop with Taskbar, Icons etc is displayed on the TV. Thats not what i want! I want that Windows forces the dualview mode so that i can turn on the TFT (primary) later while i am still looking tv on the second.

Something i have to say: Sorry for my bad english

Thanks in advance.

Hi, i find out that i have to turn off the monitor auto detection. For Catalyst driver there is a option in the controll panel but in forceware i cant find something like "use manual detection only".

Any idea to turn off auto detection for nvidia cards?

I haven't had an NV card in years Bro but did search around and came some info regarding dual monitors and auto detect settings for NV cards. Hope it helps

Quote:

Dual Monitor for nVidia Cards:

Always connect the two outputs before turning on the computer (the VGA, Composite TV-Out, and/or DVI), and make sure the TV is on the correct channel. Then you must configure the nVidia card in Dual Monitor (without the program running) - enter the Display Properties/Settings/Advanced, enter the nVidia manafucturer tab (i.e. GeForce), enter your nView Wizard. Click Next through every option except disable Window Spanning to "No Spanning", Dialog Repositioning should be "No Repositioning", and when prompted for the screen layout select "Dual View" where the screen is 1 and 2 and that both show a seperate window (not mirror or stretched). When you accept the configuration, you should see a screen on the TV and on the main monitor. If they are exactly the same (with desktop with icons) then you chose Mirror, change the option. Check in the Display Properties that the "Extend my desktop to the second monitor" is checked - your result is the second monitor just the background desktop (no icons). Now you are ready to run Swift Elite, if the video window does not end up in the second monitor (turning it black) then set the Auto Detect option and restart the program.

Thanks mac daddy for your help. But the problem is greater than i expected

After i playing around a little with dual view, overlay and clone modes iam very unhappy with nVidia. So i switcht back to single display mode and unplugget the tv-out cables.

So what happens now? Yes right! I start my computer with monitor power is off. Reason for example the pc acts as network printer host - so there is no need to power on the monitor. So what happens if i turn on the monitor while windows is running? Right - Nothing. Display is black.

nVidia decided that if there is no display at startup the user has no need for a video output.

Why nVidea implements stupid features like this?
That worked over years with my mx card, over years with my ti4600 card, it works over years with my x800 card and it works with the windowsXP standart driver. And now? nVidia decided to implement supid things. I get a 8800GTS and iam really pissed off from nVidia. That "autodetect" feature or how it is called is tottaly useless.

I want that ForceWare never change my display settings on "his" own intention. Intelligent Software is a mythos, so let it how it was over years!!!

I wait one day left to find a solution, if it faild my card goes back - its useless for me and for all multimedia user with two displays. TV-Out is a fake!

It certainly is a lot more difficult than it should be isn't it. I have a Radeon 9800 here just hook up svideo or RGB out and it works. Wish I could be of more help but we can't design NV's cards for them

I have found a registry entry to force displays. With this solution i have a picture on my display when i turn the monitor on while windows is running. One point left on this is that the resolution is wrong. 1600x1024 instead of 1680x1050. I think i have to write a little toll which changes the resolution if my monitor is available. With that i can life and i hope nVidia changes her driver back

One question left. In the nVidia NGO Drivers there is an option to turn VMR on. Is there a possibility to do the same thing with no ngo installed (with official drivers)? A registry key or something else? I need that VMR thing for my DVB App when its running on a second display.

thanks funny

Edit: Found the key with the tool named nvHardPage
