So, I'm in the process of switching from ATI to nVidia for a couple of reasons. The card I'm running is a 9500GT (running as a secondary). This is all on a clean install of Win7.

And now I'm remembering something about nVidia in a life past: WTF is up with resolutions / refresh rates?!

I finally got the thing to recognize that it can do more than 1600x1200 using another inf. Great.

But now it's doing the apesh*t refresh reporting. I try to set a mode, 1920x1080, and I get for vertical refresh:

nVidia control panel: 48hz
PowerStrip: 60hz
Barco: 86hz (!!!?!)

None of these are even close to multiples. It looks like powerstrip is completely clueless, but its adjustments do indeed adjust the image.

nV's custom resolution maker will let me make a 72i mode, test it successfully, and then set the aforementioned 48p no matter what I tell it to do.

If I try various things, I get the Barco reporting insane vertical refresh rates, losing v-hold and going nuts until I drop it down to 720x480 (even with previously working resolutions), the video card suddenly just not sending anything out even though it thinks there's a display there... It's total mayhem.

What in god's name is going on here?! Sad

You need to test it all on a CRT monitor.

Uninstall Powerstrip.

If you create an interlaced res on Nvidia control panel you must use 540 rather than 1080...and you need to specify 72i as 36i.

The powerstrip timings are different to the Nvidia timings. Powerstrip timings will either fail on Nvidia, or you will get 144i.

I actually did post an Nvidia image here once, dunno where it's gone now.

And feel free to kill your Barco with whacky timings. I'd rather kill a valueless CRT monitor from the dumpster. Once you have a stable timing on the monitor, then tweak it on the Barco.

I haven't hurt my Barco with bad timings. The only bummer is when you whack it out real bad and can't see what you're doing. Powerstrip has a reset to original settings that helps get you out of that real quick.

both ATI and Nvidia are quirky. I switched to nvidia once and just didn't get it so went back to ati. Once ati is set to "i" resolutions powerstrip takes over really nice.

OK, well...

I've tried both the 'all resolutions' thing some dude wrote for his geforce, and the FWM 900 thing.

With the former, I could get nV to create a 1920x1080 custom 72i resolution, as long as it used auto timings. change them, and it said they weren't supported.

With the latter, it *first* said that the test was successful, and in fact, it was; I could see the PJ running correctly. I accepted.

It set the resolution back to 1680x1050, and inexplicably simply refused to set the new 1080 resolution in the future. It always jumped back to 1680 with no explanation or error.

I went and re-edited it, to make sure everything was correct, and this time it FAILED the test, saying the display didn't support it.

f*ck this sh*t. nVidia fails.

perisoft, is that with powerstrip installed? or just the nvidia drivers alone? I wonder if you did a slim install of just the nvidia drivers without all the control panel shiznit, if powerstrip would work better for you. Seems to me like nvidia software is overriding things on you.

I'm using the radeon 4350, it was like $30. amazing how cheap these cards are now and with full dxva acceleration for x264 material. amazing... when you can get them to work right eh?

It's not much fun with ATi and Powerstrip either.

I installed a 4850 from a 2600XT, and then spent 3 hours getting it to work....

No powerstrip, just using the nV stuff like Mark said.

In the end I said 'f*ck it' and hooked the PJ up to the secondary on the Radeon 4890. Reinstall powerstrip, set timings, 15 minutes later it's running 72i. In fact, it was switching between p and i correctly, now that I think about it. Powerstrip works perfectly.

Worst thing, though? Whenever you even MOVE THE POWERSTRIP WINDOW it switches the active output to the one the window is on. Click to select secondary, move window for some reason, go to advanced timing and change to interlaced... WHAM, the LCD monitor / DLP projector you're using for setup barfs on the weird input and voila, you've got a one-way ticket to f*ck***. f*ck you, entech - what the f*ck were you thinking changing user input without notification!??$!

Yes, that quirk of Powerstrip causes chaos...

Got me plenty of times...
