Adjust Preview Window Display?

[THoff]

Even though NVIDIA changed the Control Panel applet look, some of their drivers still support the old style (which I prefer as well). For awhile you could choose, but I think that feature has disappeared now as well.

However, there are two registry keys that control this, and you may be able to switch back to the old style that way. Paste the following into Notepad, save the contents into a file with a .REG extension (such as OldCPL.reg), and then double-click on the file to import the settings into the registry:

REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NvCplApi\Policies]
"ContextUIPolicy"=dword:00000001
"TaskbarUIPolicy"=dword:00000001
;hint: 1 = old panel, 2= new panel, 3= both panels

As I said, it works with some of the NVIDIA drivers, but not all. It's worth a shot.

No problem - glad it works for you.

I believe that pre-vista ForceWare drivers offer you a choice to run the NVIDIA control panel in 'Classic Mode' which makes it what it used to be, minus a couple of newer controls.

Alas, with Vista ForceWare drivers, you don't get a choice anymore. I've gotten used to finding things now, so my dislike/like ratio is 50:50.

Happy editing!

Kenneally,

In the end, I reverted back to an older Nvidia driver 84.36 as I liked the overlay controls there better than the newer version so now all seems to be working.

Thanks!

Kenneally,

I got the problem fixed. Here's what I did. I installed the latest Nvidia drivers 91.85. Now the settings are sticking in all apps. Must have been a problem with previous driver.

But here's something weird. It seems like every time I download a driver revision from Nvidia, they have decided to change their contol app design. They have done so again with the 91.85 drivers. So naturally, they are unfamiliar to me. Specifically, they have changed to a webpage like control app. When you finally get to the video settings, now they offer a bunch of sliders for controlling things as well as the familiar graph on a different tab. There is one page of settings for desktop colors and another page for video colors. On the desktop color page, there is a preview picture shown next to the controls. On the video color page where the preview picture should be, there is nothing and above it it says 'video overlay disabled'. When I grab, for example, the brightness slider and bump it up, the brightness changes in Media Player Classic which is also open. This is wonderful and wasn't happening before with the older driver for some reason.

Wonder why it's saying 'video overlay disabled'? Seems like these controls are working and Edius now uses the adjusted settings.

Thanks!

NVIDIA's site gives the full listing of hardware vendors and their version numbers to check. You might even be able to pull down an NVIDIA reference driver to double-check things.

Kenneally,

I'm currently using ver 91.36. It may be that an older version would correct this. I'll look into it.

Thanks!

[GrassValley_KH]

What version of forceware drivers are you running on the graphics board?

Might need to rollback..

(contrary to some beliefs, NVIDIA driver releases aren't always flawless)

[Mike Truly]

Kenneally,

I think I may have isolated this further to some problem with the Nvidia settings.

Not only do the settings not stick in Edius, but they also don't stick in Media Player or Media Player Classic (and probably other apps).

If I open the apps, the Nvidia settings aren't working... click OK, they work. Close the apps and re-open, the settings aren't working again. Seems the settings aren't sticking.

What's weird is I have changed nothing on this system in ages. Not sure why it would change. Will explore further.

Thanks!

Oh dear..

Starting to get outside the realm of my knowledge - have you talked to the guys in Tech about this? They may have some 'canopus.ini' tweaks to try and resolve the issue.

[Mike Truly]

Kenneally,

Yes I am using NX and it does do the same thing when I switch project settings from the 720p settings to an SD OCHI mode setting. I just tested it.

I switched settings... saved project... restarted Edius... opened SD project... image dark... Nvidia settings-OK...Edius image gets bright...restart Edius and reopened SD project... image dark again.

Thanks!

[GrassValley_KH]

Your system is using NX right? Does this weirdness happen if you do some tests in Generic OHCI mode? (ie. bypass EDIUS hardware)

[Mike Truly]

Kenneally,

The Nvidia settings ARE being saved. Each time I revisit the Nvidia dialog, the curve I created there for the Overlay is still there.

I just tested again. Did a re-boot, checked the Nvidia settings... curve is there for overlay. Closed the dialog. Opened Edius4.24. Image is dark.

Opened Nvidia dialog, changed nothing... clicked OK. Dialog closes and Edius image gets bright as desired. Image will stay bright during session but will change back to dark upon next Edius restart. Also, if I start Print to File>Procoder2 from Edius, when PC2 is done or I cancel the PC2 window, Edius image goes dark again.

Not sure what I'm doing wrong but the overlay settings just won't stick.

Thanks!

[GrassValley_KH]

Is the NVIDIA control panel saving your settings? Or trashing them each reboot?

[Mike Truly]

OK, now it seems to be that the problem is that the Nvidia overlay settings are not consistently being used in my Edius4.24.

For example, I start Edius and see that the preview window looks too dark. I open the Nvidia controls (and the instant I do - which switches focus from Edius to another app, the Edius preview display of the image is brighter and exactly what it should be). Even though the displayed Edius image looks correct, I know it's because focus has shifted and as soon as I go back to Edius... it's dark again.

So I go ahead and adjust the Nvidia overlay to make it brighter. When I go back to Edius, now the preview image is brighter as desired. Problem is, later when re-starting Edius, the preview window is shown as dark again and I have to go back into the Nvidia settings to goose it to be bright again. This is on a QuadroFX 3400.

Anyone seen this type of behavour before?

Thanks!

[Mike Truly]

THoff,

Thanks. I knew there was somewhere where I had done it before. Strange thing is, I hadn't changed the display on this system so I wonder why it appears darker now. I'll look into it.

Thanks again.
