== IBM ThinkPad Port Replicator II ==<br />
The [[ThinkPad Port Replicator II|Port Replicator II]] (Model # 74P6733) is the cheapest dock IBM sells. It contains basic pass-through connections for notebook ports, including power pass-through. It comes without integrated power supply but provides the same power jack as found in a ThinkPad, so you need to use either your Thinkpad AC adapter or another IBM AC adapter. Besides all the pass-through ports the Port Replicator II comes with an On/Off switch and a slot for a cable lock (only for the dock though).<br />
<br />
===Features===<br />
* Passthrough ports:<br />
** Ethernet (RJ45)<br />
** Modem (RJ11)<br />
** USB (1-port)<br />
** DVI<br />
** VGA<br />
** Serial (DB9-M)<br />
** Parallel (DB25-F)<br />
** PS2-keyboard<br />
** PS2-mouse<br />
** Diskette drive<br />
** Audio line-in and line-out<br />
* Kensington Lock connector<br />
* Power button<br />
<br />
===Pros & Cons===<br />
* Positives: Inexpensive ($149 Retail)<br />
* Negatives: Requires AC adapter, only one USB port, doesn't secure Thinkpad<br />
* Compatibility: X20/30, T20/30/40, R30/40/50, and A20/30 series (Does not support X40/41, R40e/50e, or G40/41)<br />
* Warranty: One Year<br />

==DVI pass-through==<br />
LCD monitors are getting larger and higher-resolution. Currently, DVI based on 165MHz TDMS transmitters can only (officially) support 1600x1200x32 at 60Hz, which is the resolution of your average 20" non-widescreen LCD. IBM's driver support for this resolution through DVI ports on docks has been inconsistent. Also in Linux you might experience [[Problem with DVI throughput|problems]] even with this resolution and IBM officially states that the pass-through DVI port only supports resolutios up to 1280x1024. Read [[Problem with DVI throughput|our page]] of information on how to solve these troubles. Has anybody ever tried to connect 2 external monitors (VGA + DVI) ?<br />

=== Linux driver - OpenSource ===<br />
This adapter is supported by recent versions of the 'radeon' driver as found in X.Org and XFree86.<br />
<br />
====ThinkPad LCD====<br />
Display on the internal LCD works as long as you set the monitor settings correct<br />
<br />
==== External VGA port ====<br />
Works fine with open-source drivers. It turns on automatically when an external display is present. It can also be used for dualhead with Xinerama (with different resolutions on both screens) or MergedFB.<br />
Has anybody ever tried to connect 2 external Screens (VGA + DVI via Portreplicator) ?<br />
<br />
==== SVideo port ====<br />
SVideo out is supported by the ati.2 driver from the [http://gatos.sourceforge.net/ GATOS project].<br/><br />
Read [[How to get TV-Out working on ATI graphic cards|here]] how to set it up.<br />
<br />
=== Linux driver - Proprietary ===<br />
ATi's proprietary Linux drivers support only the R200/FireGL graphics chips and above. The Mobility Radeon 7500 is based on the R100 graphics chip, so the only driver available for Linux is through the open-source radeon DRI.<br />
