Thinkpad t41 dual monitor pivot

I have recently got a new monitor with pivot feature. I am not able to make it work so it is usable though...
I use arandr (xrandr frontend) for setting xorg, but as soon as I set the orientation of the secondary monitor to left (to use pivot), even moving windows around is slow as hell. Setting a lower resolution and/or color depth didn't help either. It almost seems as rotating the secondary screen eats all of my system ressources. Is there a way to make it work? The desired setup would be: laptop lcd normal, primary, 1024x768 + secondary lcd, pivoted, 1280x1024. Having both monitors aligned normally works absolutely fine, even when moving a glxgears window around.
Specs (thinkpad t41):
Pentium-M 1.6
1GiB RAM
Mobility Radeon 7500 (32MiB dedicated)
Openbox+latest Xorg, xorg.conf is pretty much default...

it seems I have to respond myself to almost all of my questions on the forum lately LOL. Maybe I am not clearly expressing myself
Anyway, after talking to some people on IRC, I have found out that in order for rotation to work, I would need to enable the EXA acceleration method. Futhermore, there is a 2047x2047 texture size (virtual desktop size) limit for the radeon 7500 hardware acceleration. After messing with different settings, I finally gave up after finding a bug in xrandr which prevents me from using the requested mode correctly (see http://bugs.freedesktop.org/show_bug.cgi?id=20083).

T530 lenovo thinkpad, need dual monitor cables/converters: just a USB to split into 2 VGAs?

I want to run dual monitors from my T530, or, better yet, from the 4337 docking station. Can I just get a USB with a split pair of VGA ends?

you want to run two extra monitor in addition to the internal LCD? The T530 with the series 3 workstation dock will be able to support that, if you want to use displayport or dvi out.
If you need vga, you can get a USB2VGA conveter, and use the other vga port on the laptop as the second vga source. If you need to have 2 vga to give the exact same video signal, you can get a vga to dual vga splitter cable.

Thinkpad W520 with Minidock+ Series 3 - Dual monitors and USB fail sporadically

Hello there,
I wonder if anyone has experienced problems ThinkPad W520 and Mini Dock Plus Series 3 (Part number: 433830U)? I run into problems with dual monitor and USB devices.
For dual monitor setup, sometimes only a single monitor is detected, sometimes no monitors are available in the NVidia control panel. Rigorous display detection doesn't help. Disabling Optimus in BIOS doesn't seem to affect it. After I dock and undock couple of times, reboot, unplug the power cord, it seems to resolve and both monitors work fine.
Also, I run into troubles with USB devices (keyboard/mouse). Sometimes they are not detected at all, but if I plug them into different USB ports on the mini dock, they are detected and work fine.
For me this problem happens about 50% of the time when I dock... Any ideas, insights or suggestions are greatly appreciated. Could it be a faulty Thinkpad, docking station or may be both? I really to upgrade next time to W530, but I've been through so many problems with W520, so I don't know if it's a good idea...
Thanks so much.
Solved!

If system update isn't finding anything, and the system works just fine on its own, it could potentially be a faulty Dock.
It could be overloaded. Could you try testing the dock using just one monitor, and no keyboard or mouse, to see if you run into the same issue. It would still be a faulty dock, but it may be a potential workaround for the time being.

Thinkpad T420, Integrated Graphics, Dual Monitors

Warning: this isn't really a problem thread. I've looked and looked but can't find a definitive answer for my question.
I'm seriously considering a Thinkpad T420 for a new work laptop. I've heard great things from many people, but the most important question has yet to be answered: if I get one with integrated graphics (Intel HD 3000), will dual monitors work with VGA and DisplayPort with a DVI adapter? It's crucial that I'm able to use two external monitors simultaneously and I'm sick of using TwinView because I can't rotate a monitor. Can anyone confirm that this works?

according to tabook.pdf
Intel HD Graphics 3000 in processor,
external analog monitor support via VGA DB-15 connector and
digital monitor support via DisplayPort (supports single-link DVI-D via cable 45J7915);
supports dual independent display;
Maximum external resolution: 2560x1600 (DisplayPort)@60Hz;
2048x1536 (VGA)@75Hz; 1920x1200@60Hz (single-link DVI-D via cable 45J7915)
So, it looks like the hardware is certainly capable of it.

Dual-monitor setup + screen rotation

Hello, I want to use my desktop computer with a dual-monitor setup. I have connected both monitors successfully, but problems arise after this point.
The first problem is that they both just display the same screen and that xrandr only detects one screen called "Screen 0". I can change the screen resolution with it, so at least it sees things correctly, but I don't know how to extend my screen area to a new desktop. Not sure if this is relevant, but they're both monitors of the same model.
output of xrandr wrote:[user@archbang ~]$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200

800x600 0.0

The second problem is that I can't rotate my screen (I want this because it has pivot functionality). I'm using the xf86-video-ati driver.

Dual Monitors on t430

I just received my new t430 and having issue with dual monitors. I am using the Intel HD 4000. I have it connected to a ThinkPad Port Replicator Series 3 (Type 4336). The docking station only support VGA connection. My new t430 only has a VGA connection on the side.
I have 2 monitors. One is connected to the VGA on the docking station. The other is connected to the VGA on the t430 itself.
While the machine is docked, Monitor #1 that is plugged into the docking station works, while Monitor #2 that is plugged into the t430 does not.
While undocked. Monitor #1 does work (obviously because undocked), but then Monitor #2 does work.
So I know both monitors are working and configured for VGA input. My questions is, why can't both work at the same time? While undocked, I can use laptop screen and Monitor #2 as a dual monitor. So I don't believe there is something wrong with the Operating System (Windows 7).
I used to be able to do this on my t420. With one monitor using VGA, and my other monitor using a DisplayPort. But looks like this model my company purchased doesn't support a DisplayPort (at least don't have the connection.)
Any help is greatly appreciated.
Thanks.

T420 and dual monitors using eGPC?

Hello all,
I just purchased my first ThinkPad, a T420 (4180 62U). So far I really love this machine.
Unfortunately for me, I didn't realize that this model does not support dual external displays with the built-in graphics processor.
I was wondering if anyone has had success with using a external graphics card along with the dock so that they can have the dual external monitors and the laptop screen running.
If so, what hardware should I be looking at? I would welcome any advice or recommendations.
Thanks
Zim

Thanks for the quick reply!
I haven't actually tried the dock yet. I was going to order one, then I read that you had to have the Nvida Optimus graphics card to actually do a dual monitor + laptop screen set-up which my ThinkPad does not have.
It's my understanding that the intel graphics HD 3000 allows another monitor, it just doesn't support tow external monitors.
Am I mistaken about this?
If so, then I'll be real happy, because using 3 screens will be a great help when using Cisco Packet Tracer simulator, reading instructions and taking notes.

T410 Dual monitor support with integrated graphics

I am considering purchasing a T410 with integrated graphics, but I need to make sure it will support dual digital displays (with a dock of course). I use a T500 for work, and when I switch to the integrated chip, I am unable to use dual monitors.
Can someone confirm that the T410 (integrated graphics) can use dual digital displays with a dock?

Should work. That NEC is 1920x1080 which is suported on the single-link DVI. DP can handle even more. The dock has both DVI and DP. Your ThinkPad supports the 2 monitor outs. My understanding is the ThinkPad LCD would need to be off when you do this; the specs on the dock mention max 2 monitors simultaneously.

T400 Dual Monitor Recommendation

Hi all,
I want to use dual monitor with additional LCD monitor.
But I do not know much about dual monitor resolution setting.
Can I ask if this monitor works well with T400 as an additional extension display?

There have been problems with 1600x900 monitors on Thinkpads - supposedly a BIOS fix in the works.
I would go after a more standard 16x10 ratio. Also, will you be using the VGA port, or DVI from a base station?

T61p dual monitor with docking station, maximum resolution

I wonder what is the maximal resolution one can get with the quadro fx 570m. I specially want to reach the 2560x1600+2560x1600 with two 30'' monitors. Does anyone know about it or have experience with it?
dual monitor with docking station

You will need the huge docking station with Dual-Display Port & DVI. Then it should work, but you will only be able to use 2 displays at once (one external+laptop LCD or 2 external). But I think you already know that.
VGA on such resolution would be suicidal and i doubt it would even work.

PSE 6 - Dual Monitor Full Screen Problem

I've got a Thinkpad (with NVIDIA Quadro M140 integrated graphics) connected via DVI to a Samsung SyncMaster 206BW monitor using Vista Enterprise.
I've set up my workspace as Dual Monitor, DualView. My Font DPI is set at 96 (Default).
When I click Maximize on the Thinkpad LCD, PSE 6 opens fully and correctly.
When I click Maximize on the Samsung external monitor, PSE 6 opens a window that is larger than the monitor AND there are no bars at the bottom to shift the display. Therefore, I cannot see about 15% of the right side of the window when in Maximum/Full Screen mode.
PSE 6 appears to be the only program that has this problem.
I cannot adjust the monitor, since I'm connected via DVI.
All video drivers are current.
Is there a fix for this problem?

I haven't seen this occur on my Macbook pro with secondary or triple monitors. Is this happening with all fullscreen content (eg. YouTube)? What browser and Flash Player Version are you using? Also, is this a retina macbook?

Dual Monitor Capability

I was wondering if there was a way to have dual monitors hooked up to a TSeries ThinkPad? I currently have dual monitors and a Lenovo tower and was going to switch to a TSeries Thinkpad w/docking station but I don't want to lose the dual monitors when I am at my desk. Can anyone advise?

Yes it is possible if you use the Advanced Mini-Dock, there are several posts on how to do this.
The easiest way to set it up is to attach one monitor to the
dock's VGA and one to the dock's DVI and create a profile in
ThinkVantage Presentation Director, (shortcut Fn+F7).
When
creating your profile and selecting screens there is the option to
select output to DVI and VGA, this is only available if you first
de-select the internal screen. It will also allow you to clone the
screens or select extended desktop.
When docked the VGA port on the TP is disabled.
Another method would be to use the DualHead2Go solutions from Matrox.
Hope this helps

How to set up dual monitors with a Mac Mini

The Mac Mini has only one video output port. I very nearly didn't buy a Mac Mini system because I need to work with two monitors. I use the second monitor to display information in Web pages, PDFs, and Word documents while I am working in the main window.
However, I discovered after quite a bit of Googling that it is possible to set up dual monitors using an inexpensive USB video adapter (about $70).
So I bought my Mini (1.83Ghz, 2GB RAM, 200GB 7200rpm Seagate Momentus), and I also bought a USB video adapter called the EVGA Plus.
I've installed this system and used it now for a week, and I am quite pleased with it. So I thought I'd pass this information along to anyone who's interested. Please note that, although this is my first post to this forum, this isn't spam -- I have no financial relationship with any of the companies mentioned here, other than as a customer.
LINKS
EVGA Plus:
http://www.evga.com/articles/409.asp
Their literature does not mention Mac OS X compatibility. However, the underlying technology is made by Display Link. You can download beta Mac OS X drivers from their site:
Go to Display Link to download the beta Mac OS support -- see
http://www.displaylink.com/macbetadrivers.html
The disk image includes a very well written PDF document that explains the driver's status and limitations.

NOTES
* The DisplayLink driver is beta. It doesn't support 2D or 3D accelerated graphics. You can't use it to display iPhoto slide shows, for example. However, I need to be able to display a Web page, document, or PDF in the second monitor while I am working in the first. I've found this solution to be quite acceptable for this purpose.
* Several other companies make USB video units that use the same DisplayLink support, so they should work, too. However, they are more expensive -- largely because they're set up to function as port expanders, I believe. The EVGA Plus was the only unit priced under $100 when I did my search.
* USB does not have very much bandwidth, so you might be surprised that to hear that it's possible to use USB to drive a monitor! You'll find that the display isn't as fast as DVI, but for my purposes, I've found it quite acceptable.
* The EVGA Plus comes with a terrible USB to mini USB cable that will cause all sorts of display problems. Replace it with the type of cable that is used to hook up digital cameras to a USB port.
* Once everything is installed, you can use the Displays in System Preferences (or just click the icon on the menu bar) to adjust the second monitor. You can choose display resolutions (depending on your monitor's ability, of course). Rotation works. You can also right-click the second monitor and choose a different background color or graphic.
Don't expect miracles. Don't go this route if you want to run videos or games in the second monitor. And if you get an EVGA Plus, replace that horrible cable!
I hope this information is helpful.
Bryan

There has been quite a lot of discussion here about driving twin displays with the mini, and more recently about the potential for USB video adapters to facilitate this, particularly in the light of several vendors claiming they have suitable MacOS devices and drivers 'almost ready'.
The DisplayLink solution seems to be the one most suggested as viable, though it's a pity they have not yet been able to move their drivers from beta - I suspect that puts a few people off. It's therefore good to hear of a real-world experience that should help others decide whether or not to go this route!

Lenovo 3000 N200 0769-ALU Dual Monitor Support
