Could this be the video card? (GeForce 6800) |
|
|
I recently got a new computer (Dell 8400) with a 256 MB nVidia GeForce 6800
video card. The monitor is the Dell M993s 19" CRT. I find that I can not
use any refresh rate above 60 Hz. If I set it higher, I have an
unacceptable amount of wobbling in the picture. I have tried numerous
combinations of resolutions, color settings, and refresh rates, all with the
same result. I updated the monitor drivers and am using the latest video
card drivers from the nVidia web site (driver 6.6.9.3). Dell even sent me
another monitor, with the same result. Any ideas? It seems that there is
no reason I should not be able to use a higher refresh rate. The monitor
default setting is 75 Hz. |

I don't know what resolution you're running at, but the wobbling is
indicitive of something far more serious.
Either Dell got a bad batch of CRT's, or you might have tremendous EMF
interference near your system. This can be due to bad wiring,
interfering devices, or sometimes a big pair of speakers or your PC itself.
It might be a bad card, but I've never heard of one doing that at only
above 60hz for any resolution.
First, isolate your PC to make sure it's not a local interference
problem. Move it into a large open room away from equipment and plug it
into a grounded surge protector or UPS; just a bare bones system. See
if it still does it. Barring that, I'd just RMA back the video card
through Dell's warranty. |

All right - I've identified the problem at last, but I would appreciate any
suggestions as to how to solve it. I finally moved the monitor, computer,
mouse, keyboard, and surge protector to another room, where everything
worked perfectly (I should have tried this to start with). Then we tried
hooking the computer up with an extension cord to the same plug we had been
using before and, again, everything worked perfectly at all refresh rates.
Incidentally, the image is much nicer at refresh rates of about 75 Hz or
higher. I can definitely tell a difference in comparison to the 60 Hz,
though, honestly, I can't distinguish much difference at >75 Hz. Anyway,
the problem is clearly something about the location of the computer, but
it's a daunting task to try to imagine what specifically is doing this. Any
ideas as to the most likely culprits? Is there any way to shield the
monitor from other frequencies? |

The microwave makes the picture "wobble" on my Dell, located in another |
room, but on other side of monitor wall..
Not many microwave meals for me (Yippee) |

If you can't find the source of the electromagnet interference, the only
recourse you have is to move the system. Maybe you only will have to move
it a few feet.

Do you have a cordless phone base station in the computer room? I have to
keep mine well away from the PC

There must be some eletrical/electronic device on the other side of the wall
that is causing the electromagnetic interference. It could even be a TV
(CRT) or even another computer monitor (CRT). It could be a medical device
like an MRI scanner, CAT scanner, X-Ray machine, etc. It could be an
elevator shaft on the other side of the wall. It could be an electric motor
in an appliance.
If you want to keep your system at its original location you would have to
remove the source of the EMI (Electromagnetic Interference), which may be
impossible to do. I can't think of any cost effective shielding that you
can construct to prevent this.
Another solution is to replace the CRT monitor with an LCD, which is immune
to EMI, and provides a brighter clearer image with no flicker.
