Dell 2001FP LCD w/ T41

I just got my dell 2001FP monitor and planned to use this as my external monitor for my T41 laptop. When I plug in the 2001FP LCD, I notice that there is ghosting. I've searched this and some users said that they use the 2001FP but i'm not sure if they used it for their thinkpads or for their laptops. Does anyone have any information about my problem? Thanks.

which ghosting d you mean? There are several definitions of the word - one is related to MOVING images and quick color transitions. That is a function of the speed of the pixels in the LCD as well as your eye sensitivity and there's not much you can do about it.

However, if you're seeing the other form of "ghosting" - multiple images or faint images behind each other - "ghosts" - you can rectify this easily. Get yourself a better quality VGA cable if you are using analog. I don't know about the 2001FP, but I know that Dells lower monitors use a HORRIBLE, thin and barely shielded analog cable. It's a POS, get rid of it if you have one and go pick up a decent fat VGA cable.

Alternatively, buy a Thinkpad dock that has a DVI port on it, and then use DVI for the 2001FP. It's much more tolerable of interference, plus most DVI cables are better quality than today's VGA/analog.

thanks for your reply.

The ghosting I'm talking about is the 2nd one you mentioned about faint duplicate image to the right of the original image. Here is a picture of what it looks like. These pics aren't mine but its the same thing:

I think the DVI output on the docking station allows up to a res of 1280x1024, but my monitors native resolution is 1600x1200. I'll go to a store and try to pick up a better VGA cable and see if that helps.

That's a different issue for which a new VGA cable won't address. There have been several threads on this, e.g. http://forum.thinkpads.com/viewtopic.php?t=1122

Hi there.

I was wondering on the ibm t42 which has a ati 9600 64mb video adapter, what is the max res does the vga port support? I just want to find out as i am thinking to get a lcd display to connect to it for watching movies:)

Cheers.
Kenn.

Will simply replacing the cable fix this ghosting problem? I'm having the same issue, but not sure where to find a good cable.

Are you using VGA or DVI?

You shouldn't be getting any ghosting with a digital DVI connection. I'm not sure replacing one VGA cable with another will make any difference though. The better solution would be to convert over to DVI.

on models up to the T41p you could get full 1200x1600 resolution in DVI by using a different driver from ATI and a hack found on the internet..

i have not tried this recently..

it is NOT your display, as mentioned above..

i haver three FP2001 and they are perfect..
i replaced three FP2000 to get the smaller bezel (important when you use three, side by side)..

a good VGA cable SHOULD fix the problem..
one of the FP2000 displays came with a defective cable from DELL..
your problem COULD be a bad connection to either the TP or the display..

I'm using VGA, so I'll try to borrow a different VGA cable and see if that fixes it. As for DVI, I dont have a docking station yet, so I'm stuck with the VGA connection until I can buy one.

By the way, I'm actually using a 2005FPW off the Thinkpad, not a 2001FP, but the problem was identical. I've read up on the driver hack issue, and will do that if/when I get a docking and DVI connection.

So I got another VGA cable (Dell, but it is thicker, so I'm assuming shielded more); however, it's still doing the ghosting problem. Will DVI get rid of this, or is this the LCD or my computer?

Just got my 2001fp yesterday and the picture is absolutely perfect and gorgeous with DVI. Since DVI is a 100% digital signal there should never be any sort of ghosting or artifacts. When a digital signal loses coherence you get a different sort of interference pattern. The picture will basically freeze and then break up into a checkerboard sort of pattern. I see this on my digital TV monitor when the satellite feed gets weather interference.

I bought a mini-dock on ebay and can't be happier. The picture quality over DVI using the mini-dock is noticably better than via VGA. My VGA picture is still acceptable, none of the ghosting that you describe. But DVI is clearly sharper.

Your problem could also be a bad VGA connector either on the thinkpad or on the monitor. Perhaps there is dirt or corrosion inside the VGA output on your laptop? Or perhaps it is loose or something?

Your monitor came with a DVI cable. Perhaps you can borrow a thinkpad dock from someone to see if DVI solves your problem?
