2405fpw prob

[Xed]

After waiting about a month for dell to ship my monitor I finally got it yesterday. Thankfully unlike the hell that was my 2005fpw purchase, this one came with no backlight bleeding and no dead pixels. =)

My problem is, no matter what I try to do none of the dvi adjustments I make save, so I'm unable to game at 1920x1200 because of the myriad of display issues it causes. Any help on what I'm doing wrong would be appreciated.

If you told us what sort of issues you are having we may be able to help.

Yea, I'd have to hear what issues you're having .. I've been playing EQ2 and Splinter Cell at 1920x1200 for a few days now and it doesn't give me any problem

EQ2 must be nice at 1920.. Only running 1600x1200 on it right now

Sorry, Guess I should have been more clear

At 1920x1200 the signal is distorted and I have all kinds of artifacts and such on screen. (horizontal lines all over, pixels flashing on and off, etc) Every 5 secs or so the display will freeze then start up again.

Dropping to 1600x1200 or 1680x1050 fixes it, so I'm pretty sure it's the signal. I've tried to adjust the dvi settings but after I apply them it just resets to default and doesn't actually save them.


If I hook it up to my x800xt it works fine with the reduced dvi frequency option in the drivers, so I assume I'm doing something wrong.

ati is known to have higher quality dvi than nvidia. Hook it up to the vga on the 6800 and see if the artifacts go away.

Still have distored pixels hooked up to vga

Ok, so you're having distortions with the 6800GT on both DVI and VGA ports whereas you have no problems with the x800xt ? This indicates that your 6800GT is defective.

You say that the x800XT works fine with "reduced dvi frequency" . What do you mean by that? what if you don't "reduce the frequency" ?

What other monitors have you tested the 6800GT with? at what resolutions? with which ports?

You need to give a shitload more info if you want anything more than half-assed guesses

The ati drivers have an option to reduce dvi frequency on high-resolution displays and an alternate dvi operational mode. With them off I get the same distortions, with it on the display is fine. As I understand it 1920x1200 is out of the normal dvi spec which is what can cause the problems.

The 6800gt works fine at 1600x1200, 1680x1050 and any other lower resolution with dvi on the 2405 and on my 2005fpw. I've tried to reduce the "blanking" through the nvdia control panel but it doesn't work. I've used the 75.90, 71.89 and the 66.93 drivers on clean installs. I know people here are running a 2405 without issue so either the card is bad or I've missed something.

psu??

Well, I have an evga 6800GT and a 2405FPW with the 71.84 drivers and everything works fine at 1920x1200.

This is quite the tricky problem but I think we can all agree that only the GPU and the Monitor are involved. I still think the problem lies within the card.

you could try it with a different monitor capable of 1920x1200 (might be tough to find one...) and you can also placing the card in a completely separate system to see what happens (now this definitely feasible). Use the 71.84 drivers this time. if the problem persists, the card is definitely defective somehow.

Good luck
