LCD Flicker. And windows won't keep changes to the display settings!

Dear experts,


I've seen some really strange behavior lately, like I've
never seen before.

I have a Dell 4600, with an Nvidia Geforce 5200 card in it.
To date, I've used a simple CRT monitor from Dell.
But this week, I bought an LCD screen from Sony.

There was some flicker. So, I downloaded the latest
drivers and everything from NVidia, and installed
everything. There still was flicker. So, I
decided to compare.


I also have a Sony laptop, and an LCD TV. I use
my Laptop to play DVDs on the TV. I took the 4600
downstairs, and plugged it into the TV. It had
weird display setting when I logged in, but I
changed them and it worked fine. No flicker on
the TV.

I also brought the LCD display downstairs, and
tried it with the same 4600 computer there.
Interestingly enough, no flicker.

So, what is causing the flicker with the LCD?

I also have another desktop, with an ATI card, that
sits right beside the 4600, and it doesn't give flicker
with the LCD. (I use a KVM switch to move between computers.)

So, the location makes a difference.
Upstair flicker
downstairs no flicker

But, why would I also not get flicker with the other
machine, right beside it? Strange!

The machines are XP/Linux dual boot. On the 4600,
it also flickers in Linux.

I read that perhaps the power source might have something to
do with it. So, I ran an extension from the main floor
upstairs. No difference.


So, if that is not enough, today when I boot the 4600,
the video settings are off. They are the same as they
were with the LCD TV. I change them back. And when I
reboot, they go back to what they were with the LCD TV!

What a bother!


Questions

1)
How do I set the video settings so that they stay as I
set them? when I reboot, they are the same as what I
set them to.

2)
Any ideas on what is causing the flicker?

What refresh freq did you set the GeForce card up to?

Check the refresh rate in Display Settings of Control Panel. It is more
than likely set to 75 or so. Change it to 60 to stop the flicker.

With the ATI drivers the settings you'll see without forcing the issue will
depend on the .INF file for the monitor. So the next question is, are the
settings ones that the monitor supports? Whether or not the GeForce works
this way it's best to have the proper .INF file. If the monitor didn't come
with one get it from MFG website. If Windows doesn't detect the monitor
change check Device Manager to see what the display is set for. Install the
correct .INF.

Display issues are almost always driver issues. It certainly isn't necessary
to cross post something so simple to 4 groups. Start with the video card
group. Not that familiar with Nvidia but seriously doubt it's worth
repairing anyway. Would make much more sense to get a newer card if it had a
hardware problem.

Check the KVM and all of the cables, in addition to the other
suggestions given.

Depends, are you using the VGA cable to connect to the LCD or a DVI
cable? VGA cables are analog, while DVI are digital. This normally
wouldn't make a difference to an LCD monitor, except unless if the LCD
has a crappy analog-to-digital converter built-in, then you might see
artifacts like this when connecting through a VGA cable. There won't be
any such problem if you connect with a DVI cable, since it's all digital
all of the way.

I had a bout of display flicker recently. Oddly enough, it was caused
by installing the latest Intellimouse drivers. Here's a copy of a
relevant Usenet post:

Hi there,

I just learned that the new Intellipoint Software which was shipped
with my new MS Laser Desktop 6000 causes excessive screen flickering.
It's ipoint.exe in particular.

This seems to originate from the "Window-Viewer" functionality, which
can be assigned to a mousebutton. This Window-Viewer function is taking
screenshots all the time from every program running, to build the
special screen upon them.

Even if the Window-Viewer functionality is not assigned, the problem
keeps existing.

So, this is really really annoying while working with PhotoShop or
other programs - in particular programs, which don't refresh their
screens all the time (TheBat! 2.x for example where the toolbar-buttons
in a message window keep disappearing until I move the window around
again.)

With ipoint.exe running, it's impossible for me to work with PhotoShop.
Selection boxes are vanishing from screen while still dragging the
mouse with every flicker, and so on..

It's happening here on XPSP2 with a Radon9800Pro with Catalyst 6.7.

Anyone else having these problems? Or anyone who knows how I can
eliminate the flickering?

The fix is to disable ipoint.exe from loading, using MSCONFIG.

Change the refresh rate to 60 hz to stop the flicker.

That was the solution!
Geez, you are good!

Thanks a lot!!!

I wondered why my cad programs have been blinking out, and not letting me
get my work done.
Just changed to a Microsoft Explorer mouse about 2 weeks ago.

If you diable ipoint.exe, then you cannot set any mouse buttons and windows
complains about "No Mouse found".

This needs to be fixed by Microsoft!

The real fix is to throw the Microsoft mouse as far away as posible! Then
go get a Logitech mouse.

Not sure what you mean there. True that you can't do macros and such,
but you should be able to assign any function you like to the mouse
buttons.

BTW, does Phx stand for the Phoenix Rising clan?
