Hi,

I have a macbook core duo with 2g of Ram. Recently I got a 23 inch apple display for it. I noticed that when on the internet pages seemed to load very slowly (tried using both safari and firefox). I then unplugged the display and just used the laptop which was much faster. I compared the two (with display on and without display) and it seems that web pages load much more slowly with the display on than without it. Other programs may be slow also but I haven't noticed. Anyone have a similar problem or have any idea what might cause this and how to fix it?

Thanks,

David

I would think that since the macbook has shared video ram with main ram that it needs to borrow more to power the 23 inch.

Thats just a guess btw. I don't own a macbook so never really read up on them.

There is no way to upgrade the VRAM in any Apple notebook.

I have never experienced this, nor have I ever heard of anyone having this issue. I really wouldn't have any idea what would be causing it.

I'm not sure where to find it, but I do recall reading that the VRAM in the macbook is somewhat dynamic, taking more or less as required up to a maximum. If I recall, adding more system RAM will help, but anything over 1GB won't make much difference to display performance.

If I do recall correctly, adding the 2nd display will dynamically increase required video RAM and therefore reduce the available RAM to the system. If you don't have very much RAM, this could have serious performance implications.
