The VGA is to my left, the DVI is directly ahead of me. FYI, I was also able to set portrait mode--that works fine until the computer is used undocked--the ATI drivers have to be reinstalled.

 The article says the X40 is affected by this issue---how is that?  Are there any X40 docs or adapters that give the X40 DVI capability at all?

		+	I have a T43 attached to a port replicator II 74P7633 and a pair of Samsung 213T 1600x1200 monitors attached, one each to the DVI and VGA ports on the dock. The built-in LCD is disabled when both externals are activated. I experienced that problem, but then downloaded the latest ATI Catalyst drivers and the Driver Heaven Mobility mod. I also switched off the "Alternate DVI operational mode" which fixed the DVI instability problem. I didn't have to reduce DVI frequency for the pair of monitors to run properly.
		+
		+	On a side note: I've also tried attaching my X22 to the same dock. Only the VGA monitor works together with the built-in LCD. I think the Radeon 7000 supports only dual VGA ports (one to the LCD, the other to the external). I tried connecting the second monitor to the laptop's VGA port but that didn't work. If I find a non-destructive hack to extract a second VGA signal (the one that drive the X22s built-in LCD), I'll post it here.

	It's interesting, indeed, since it's quite illogical. Did you try the newest official IBM drivers? They worked out of the box for me and at least one other person. On a T41p with a NEC 2180UX that is. I think the "Reduce DVI frequency" changes to 60 Hz, which is supposed to be ideal for DVI TFTs, but that may in fact vary.

	As I have tested several T4Xp models, it seems that after T41p (like model 2373-GHG) the DVI throughput problem has been solved by IBM using latest drivers (video and presentation director) running Windows XP, however, my users have reported "flickering" on screens randomly (like Dell 20" and 24") and that seems to be solved by using better cables. Don't expect to be able to extend or use very long cables! ((Someone correct me if I'm wrong, but the T40p model has been making trouble for me.))

−	I just tried with a T40, the latest drivers (8.133.2) do not fix the problem as the above author stated (who wrote that? Sign your posts!). I used the "Patje's Mobility Modding tool" link on the page, it worked to install the Catalyst 6.3 drivers. However, I cannot get the Catylst Control Center to come up? The CLI.EXE file is running 3 times in the background (one of which is the system tray icon), but the Control Center does not show at all. I can use the system tray icon to enable the second display (DVI for me) and change the resolution. I cannot use it to set the primary display or disable the laptop LCD. Has anyone in a similar situation been able to use the control center?

		+	The latest ThinkPad video driver, 2005 Aug 11 release, version 8.133.2-050525a-024243C-IBM, does not appear
