My screen looks all fuzzy in SLI...

At first I thought my LCD screen was defective. Then I decided to switch the the 9400 card only and bingo, the screen became clear again.

So even though I tried uninstalling the Nvidia drivers and then reinstall them, as soon as they are uninstalled or when only the 9400 card is enable, my screen is fine. As soon as drivers are installed and the 2 "boomerangs" appear (SLI) then my screen looks fuzzy with lines and weird colors.

My guess is 1 or 2 defective 260M...

Anything else before I call tech support?


Thanks,

Oliver

 

i would offer some advise but not being able to see it and having little knowledge of what your talking about I can only say
good luck

edit
fuzzy doesn't really describe what is going on and isn't going to help tech support help you

 

definately call the tech support and ask them to send u a new card.

 

its a defective card 100% certain on that. its not a problem with your display either. its the card defectively communicating with the screen somehow.
watch, plug your system into a VGA monitor and notice that the fuzzyness doesnt show on the monitor.

 

I would bet money it's the SLI bridge cable. Mine was fubar when I got mine. To test it just unplug the cable from one of the video cards. SLI will still work but you will loose a few FPS. Dell sent out a tech with a new video card with the cable atached.

 

I had something similar happen as well. The screen looked like it was running with fewer colors and there were weird lines all over the place when using the dedicated cards, but was fine using the integrated 9400. The output via HDMI on an external monitor was fine even with the dedicated cards, however.
Dell replaced my mainboard, which fixed the problem (on a side note, my sound/video stuttering issues were resolved as a side-effect to the mainboard replacement as well).

 

Thanks Gizmo. That's exactly what's happening. Tonight, before packing my laptop fot travel this weekend, it was plugged via HDMI to an external monitor and all looked fine when I shut it down.

How did you get them to change the mainboard and not the video cards?

 

I just described the problem in as much detail as possible and they decided to exchange the mainboard.

 

Well they want to change the cards first. I have my doubts because the image is fine when I look at it via an external monitor plugged in HDMI.

They get 2 chances to fix it. After that I want another laptop.

 

i had my mobo changed and it didnt fixed the issue at all. and i higly doubt its the sli cable. call dell tech.

 

I did. They are changing both 260M cards.

 

After my call to Dell support. They said it should be the cards. I told them the cards or the mainboard so why not send both items? I was told no. They will start with the video cards....

Well the tech came today after a week! Changed both cards. Problem remains. He called Dell and reported what was happenning. They are now changing the cards and mainboard. And they are sending 2 card and a mainboard! So they'll have changed my cards like 2 times in a week when we know they are not defective. Bunch of morons.

The only reason I'm being so patient is that I don't want a Win 7 only machine with all the latency problem etc.

I still can work with my 260M in SLI with an external monitor and on the 9400 card on the laptop LCD. But anymore small problems and I'm asking for a replacement...

Never had so many problems with one laptop. Guess the more you pay the more trouble you can have.

 

Ok well the tech came this morning. Changed the cards again and changed the mainboard. Laptop wasn't starting up. He said he was sure it was the card so he put back my original mainboard and left the new cards he just put in. Bingo. All is working!

So. My cards were defective. Monday both were replaced by...defective cards! Today I finally got good cards but the "new" motherboard was defective!

Gee whizz! On a total of 5 parts sent this week, 3 were defective!
