MacBook + 19" TFT DVI = Mouse problem

Hi,
I'd like to use my MacBook 2,16GHz (Mid 2007) with my external 19" TFT Dell Display. When connecting it via DVI it's almost impossible to use the MacBook trackpad or an external mouse. The mouse pointer reacts with a slight lag and then jumps, so you can't easily reach the button you want to reach.

I also experienced this behaviour with another 19" Display using DVI. And I don't experience this behaviour while connecting my display via VGA. So I assume it is a DVI problem.

For the connection I use a DVI-Adaptor which I bought with my Powerbook 12" back in 2005. Could this be the reason?

Has anyone similar problems or a solution for my problem? I already installed all available updates but this didn't change my situation.

Thx,
Christoph

MacBook, Mac OS X (10.5.1)

YES i have this exact problem with a 20" ACD - apple have not looked at it yet but i suspect it is a duff Graphics card - so a repair will be needed.

Hello,

I have a similar pb with my MacBook 2,2 bought 2 weeks ago running on 10.5.1.

When connected through mini DVI to DVI to my 17" sony monitor no pb mouse and trackap works normally
But when connected to the same screen with Mini DVI to VGA, mouse or trackpad shows jerky behaviour. it is almost impossible to work. Same when connected to a video projector through VGA.

Any clue if if its is hardware or software related ?
Do you think my MacBook needs a repair ?

Thanks

As to the original question, I'd question the adaptor.

As to the second, there is no graphics card and it's hard to say why problems come up with individual monitors. I have a 19" Hitachi attached to a MacBook and it works fine.
