Dual Screen setup with laptop

I have the ideapad u400.. is it possitble to connect 2 external monitors to this machine to have 3 displays if not.. can i use the 2 external monitors and just close the lid to the laptop to use just 2 monitors?
let me know
Thanks.

As you need to connect two external monitor with your IdeaPad U400. You can connect the external Monitor via HDMI port, if it is available in your system.
Alternatively, you will need to create a two monitor connection via the USB input with a VGA to USB conversion cable, you can purchase these cables at any local computer store. And able this feature in your system.
Thanks & Regards,
Sameer

[SOLVED] Dual-Screen Setup with ATI Catalyst

I'm having a beast of a time trying to set up X to work on my two screens.
Screen 1 is a 23" screen connected with a DVI cable. My preferred resolution for this one is 1920x1080. Screen 2 is a 17" screen (4:3) connected with a VGA cable. My preferred resolution for this one is 1280x960.
I tried using "aticonfig --initial=dual-head". This does not produce a working xorg.conf file. Specifically, my smaller monitor simply complains about not being able to display the given video mode. Running xrandr (from the main screen) shows only that output as being "connected" - the rest of them (including the CRT outputs which seem to correspond to the VGA port) as "disconnected".
I've spent about 5 hours searching for an answer to this, and the only ones I seem to be able to find are nvidia-specific.
I have an ATI Radeon HD 4850 or 4870 - I honestly forget which, although the drivers should be the same. I'm using the catalyst driver from the AUR, because I'd like to have 3D acceleration.
I've read through the entire xorg.conf man page, and tried a few things from there (including writing my own xorg.conf from scratch). Unfortunately, this seems incredibly useless, as the man page doesn't list any of the options that I seem to need (for example, I've read about and tried the "PairModes" option under "Device").
I can probably eventually figure this out, but it would be nice to have a few pointers. For example:
Should I have one or two "Device" sections in xorg.conf? Should I have one or two "Screen" sections in xorg.conf? Where can I find a full list of possible "Option" keys, at least for the Device section? Should I be using Xinerama (I've tried with and without, to no avail).
EDIT: I solved this by using the aticonfig tool some more, and not by messing around with xorg.conf. Specifically, the command:
aticonfig --initial=dual-head --xinerama=on --resolution=0,1920x1080 --resolution=1,1280x960 --screen-layout=right
I'll leave this here in the hopes that it can help someone else.

If you aren't playing games, it may be worth it to check out xf86-video-ati. Then you can configure your displays the standard way with xrandr.

Is it possible to have a dual screen setup with an iMac (2012) and an iMac (mid 2007)?

Hello Everyone,
I have two iMacs. One is a 2012 model and the other is a mid 2007 model. Would I be able to use the mid 2007 model as an extra monitor?
I was going to purchase a mini dvi to mini display port cable and see what happens but I think it would be a good idea to see what everyone else thinks. Thanks for any suggestions!

X crashes on startup with AMD dual screen setup

Ever since I bought my AMD Kaveri A10-7850K at the end of January last year I've been having trouble getting a dual screen setup to work properly. Initially I put this down to poor beta drivers, and as I had far too much going on to investigate the issue further beyond some fiddling with xorg.conf, I bought an AMD A4-4000 as a temporary solution while waiting for the Catalyst drivers to catch up.
In June last year I decided to give my A10-7850K another go, assuming that the Catalyst driver would have matured enough in the meantime to cater for the Kaveri processors. Unfortunately the situation was still the same, and I I didn't have the time nor want to be swapping processors all constantly to I decided to just give up on a dual monitor setup for the time being.
After many years of using two screens, however, it is very hard to get used to a single monitor again, and as January is a quiet month for me I decided today to have another at getting it to work properly.
My setup is as follows:
an LG LG 23EA63V connected via HDMI as my main monitor at 1920x1080
a Viewsonic VP-171b connected via DVI as my secondary monitor at 1280x1024
AMD A10-7850K APU
Catalyst 14.12-1 drivers installed from Vi0l0's repo
Xorg 1.15 installed from Vi0l0's repo
KDE 4.14.3 using kwin
KDM is launched using kdm.service
KMS disabled via nomodeset
fglrx module loaded on boot via cat /etc/modules-load.d/catalyst.conf
Tear free rendering enabled
After plugging in my secondary monitor configuring it in amdcccle to be to the right of my primary moniotor in multi-display desktop mode, everything works correctly. This even works in my preferred setup where the secondary monitor is rotated into portrait mode, although I currently have not configured rotation so as to not overcomplicate the troubleshooting.
Upon rebooting, however, X hangs with a static white cursor in the top left hand of both screens, which after a while disappears completely. I then have to unplug the secondary (DVI) monitor and hard reset the PC before I can boot into my desktop again. The bizarre thing is though that when I plug in my secondary monitor again and configure it as desired, either through amdcccle or krandr, everything works perfectly again.
This is, of course, an incredibly cumbersome way of working, especially when most of the time I forget to disconnect my DVI monitor prior to turning on my PC, hence me just making do with a single monitor for the past 7 months.
I did a complete fresh install of Catalyst yesterday (uninstall drivers, delete remaining config files, reinstall drivers from repo), to no avail.

Dual monitor setup from laptop

I am a college student and have a Dell d630 laptop and am stuck with it until I graduate. I have many hours of programming still ahead and am very sick of this tiny screen. I like to have a minimum of 4 windows open at a time and would love a dual screen setup so I could cover more ground. I would like a setup where I don't need to use my laptop screen at all and just have 2 external monitors working together (I already have the monitors). I tried doing research to figure out my best option but I know nothing about video cards or monitor configurations so I didn't get far. Could someone recommend the product or setup i would need? thanks!

Well with a laptop, you're extremely limited as to video output capabilities, the best you're most likely going to be able to do is one external monitor.

Dual monitor setup with seperate resolutions

hey guys!
i currentley run thye latest version of archlinux with the cinnamon desktop environment and an nvidia geforce 7300SE graphics card.
im running a dual monitor setup with one 27" 1920x1080 monitor and one 27" 1024X768 monitor
because they have the same physical size they line up perfectley but because the resolution is different programs/mouse cursor movement doesnt, is there any way (without changing the resolutions) to compensate this effect so that in the eyes of linux/cinnamon the monitors line up so that for example dragging a window goes seamlessley between the 2 monitors.
i HAVE found out the panning option in the nvidia x server settings, but that really isnt what i am looking for...

A magnifier following the window down to the pixel, zooming to the exact size of 540 pixels the 384 pixels window could create an illusion of just that. It would be highly impractical however, not mention all the hacking time. Even if you would manage to get two screen with different sized icons, so that they match visually, the windows and fonts resizing on the fly, wmctrl might help with windows alone, no their themes (buttons, borders thickness etc.), you would still be left with a visually differently sized mouse cursor. Technically such a feat should be possible, but who is going to code it? Nvidia?

I have a dual-screen setup - Workspace Layout Panels - not functioning properly.

I have a dual-screen setup and since updating to 10.10.2, the panels open on the main screen - and not in the positions as they were saved in a Workspace layout.
Tried trashing the prefs - which works, but when I save a new Workspace layout, it does the exact same thing.
Any help is greatly appreciated. Thanks.

Hi Christopher,
This is a known issue and the product team is working with Apple to address it. Stay tuned.
Thanks,

ITunes startup reinitializes dual screen setup

Dear all,
as a dual screen setup, I have a MacbookPro7,1 (late 2010 Core2Duo 2,4GHz 13" model, OSX 10.6.6) attached to a NEC MultiSync LCD2690WUXi via DVI-I, using the digital signal flow. I am not using display mirroring. The resolution of the external LCD2690WUXi is 1920x1200@60Hz.
Everything works fine and "as expected" until I start iTunes.
Doing this, both the MacBookPro and the external NEC monitor blank for a short time, as if the MacBook would reinitialize the displays. After doing so, I get the correct resolution on both screens back again, but all windows have now moved to the main screen and decreased in their size, so the dual screen arrangements are lost during this phase. I have to manually put everything back in place, which is highly annoying.
I suspect this behavior might also relate to QuickTime being part of iTunes?
If you have any ideas, please share your knowledge or experience with me.
Kind regards,
Jens

The only solution (well, it's not really a solution, it's a miserable workaround) was to exchange the assingment of the primary and the scondary display, including all the negative side effects you can imagine.
Hopefully Firefox will gain a higher grade of intelligence one day.

Does LR handle a dual monitor setup with different aspect ratios (16:9 and 16:10)?

Does LR 5 handle a dual monitor setup with different aspect ratios (16:9 and 16:10)?
I'm planing to buy a 27" 16:9 monitor and use it as primary together with a 22" 16:10. Does any have any idea?
Thanks

Moreover, the two monitors can have completely different characteristics. As always, you really need to calibrate/profile any monitor (with a hardware tool - Spyder, Colormunki etc). That's no more important with two monitors, but you see for sure if you don't, as two dissimilar monitors will then probably look different.

Dual-Screen Sessions with Oracle Desktop Client

Dear All,
I have read that the new version of the SRSS and SRWC support dual-screen separation with Windows 2008 R2 sessions, i.e. Windows sessions are able to determine that they are running on a dual-screen device and allow separation as you'd expect on a fat client. Does anyone know if this functionality is available via the Sun Ray software client or if I'll have to invest in Sun Ray 3 Plus devices? Has anyone actually got this working at all?
Many thanks.
Chris

OK. I've applied patch -05 to the SRSS (which is odd because I thought I'd downloaded 5.1.1) which installed without complaint and have upgraded my copy of the Mac OVDC to 2.1.9.
I've run the command (see previous post) and now I can't seem to connect to the SRSS with or without a card - it's not even connecting to the server to get a pseudo session.
What version of the SRSS patching comes with the 5.1.2 download? It's very confusing with the version numbers not correlating. 5.1.1 seems to come with patch -06 but it refuses to install...
Many thanks.
Chris

[SOLVED] Best DE for dual screen setups?

Sorry if this is a dumb question, but what is the best DE for a dual screen setup on Arch? Also, can I just use the standard xrandr method to be able to drag windows between screens, if not, what do I do?

Dual monitor setup - need laptop on the left

Hi All
I'm running a dual monitor setup - specifically a HP G72 laptop and a widescreen monitor. I use the monitor as the default and sometimes I want to use the Laptop as a secondary screen for watching TV etc. My desktop is Enlightenment, I just changed to it from Gnome. My issue is that I want the laptop to be on the left of the monitor - that's how it is physically positioned - but when I switch the Laptop screen on all my applications shift over to the laptop screen. I've written 2 scripts, attached to hotkeys, one to turn the laptop off and the other to turn the laptop on. The script to turn the laptop on is as follows:
xrandr --output LVDS1 --mode 1600x900 --pos 1600x0 --rotate normal
--output VGA1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --left-of LVDS1
This works fine, applications stay where they should be, except that the physical position is incorrect; VGA1 should be to the right of LVDS1 like this:
xrandr --output LVDS1 --mode 1600x900 --pos 1600x0 --rotate normal
--output VGA1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --right-of LVDS1
However, when I use the second script all of the applications shift to the laptop but at least the physical position is correct. The issue appears to be something to do with laptops, almost as though when it's a laptop the default monitor is forced to be on the left. Has anybody got any suggestions how to get around this issue?
Thanks
Richard

This is due to your window manager treating the two monitors as a larger 'desktop' area - that combined with your specification of the pos=0x0 you are telling it to do this.
If you have only the VGA output on, the top left corner of the VGA monitor is 0x0. If you open a window, and it is placed 10 pixels in and down from the top left, it is at coordinates 10x10 in the x session. Then you turn on the laptop monitor and specify that the top left corner of the laptop monitor should now bo considered 0x0 - but nothing is done to move the windows, so the window with coordinates 10x10 is now near the top left of the laptop monitor.
I see 3 possible ways of acheiving what you want:
1) swap the "pos" parameters in your xrandr commands so that the monitor on the left is always at 0x0 and the one on the right is always at 1920x0 (or whatever). This will leave a large area of available X desktop that is not visible - I don't know how your window manager will treat this. It might try to map windows on the laptop screen space even though that screen is not on. I know openbox is easy to configure where it tries to place windows.
2) Keep the VGA monitor always at 0x0, but place the laptop monitor at a negative offset when you want it on. I don't actually know if X allows negative coordinates like that, but it's worth a shot.
3) Configure your window manager, or use a different window manager, so that it is aware of the two screens and treats them reasonably (e.g. moves windows when the desktop area is changed).

Is a dual monitor setup with 2graphic cards possible?

HI.
What i want to do is run Archlinux on my Desktop but i dont want to miss my second monitor.
I could use both monitor on my nvidia graphiccard but i want to use the energy saving features too (wich dont work with 2monitor on one card) therefore my windows setup is big monitor on nvidia and the smaller one on the intel onboard card.
They both get recognized by lspci but only the onboard cards isy being used (the onboard card is the first card on windows too).
So is it possible to get it to work? Id really want to use ARchlinux on my Desktop too but i dont want to use it with one screen or without energy saving?
Working compositing is a must, i want to use gnome3 wich is the only reason to swich to linux for the Desktop (arch is running on the laptop for ages^^) but i dont need to, Win7 is working flawlessly fine and i didnt have to pay for it (msdnaa).
Thanks in advance!

hy do you need to clock down your card?
Most gpu have a function that clocks down the card@idle and or desktop.
In my case thats down from 850mhz(560ti)to 200mhz while using windows and 50mhz if the gpu load is low.
Thats about 20watts less then with full clock.
The problem is, that the gpu wont clock down with 2monitors on it, it stays at 850mhz.
Theres some driver tweaks for amd cards wich "fix" thatfix this (i believe its intentionl, 2monitors equals more load but its no problem with new cards...
Thats one reason i use my onboard gpu for the second monitor, it works well with windows and also means that swiching off fullscreen (games) to the desktop works a lot better, the second monitor can play a movie while playing wich doesnt work with one gpu and fullscreen.
I really dont need that with Linux since i use it for work and multimedia only but the energy saving feature is nice if the pc is on 8hours and more wich is often the case.
Can you tell which one do you run? I'm going to buy one for dual-monitor setup, and I'm looking for something that will work for shure.
As said dual monitor on one gpu works, amd can do 3monitors while nvidia can do 2 at once, that means if u intend to use 3monitors some day with ur card u have to buy an amd card.
i took the nvidia because is can use it to render videos with cuda support (its not working with all tools yet but its getting better and if it works its a lot faster then my cpu rendering).
PS: Thats one hread about the power saviing with 2monitors:http://forums.nvidia.com/index.php?showtopic=197557
since my monitors dont share the same resolution it seems that theres no way to make it work .

Strange dual screen issue with HP Folio 1040 and docking station

Hi there,
I have a laptop in a docking station. Two displays are connected using the docking station's DisplayPorts. Instead of showing me two separate displays like I'd have expected, xrandr seems to "see" only one large screen.
Laptop: HP EliteBook Folio 1040 with Intel HD 4400 graphics card
Docking station: HP 2013 UltraSlim Docking Station

eDP1 is the laptop's built-in display, while DP2 seems to represent _both_ displays. When I select 1920x1080, the two displays show the same. When I select 3840x1080, however, the two displays show a side-by-side setup, such that X11 spans over both of them. While I'm happy that I'm now able to make use of the second display, this obviously breaks some software stuff, like fullscreen video in vlc, for example. Any suggestions what I can do about that? Is it possible to software-split the screen such that it looks like a normal dual-head setup again?

You could define two screens in xorg.conf similar to last post here. You would have to select the screen using the -display switch or the DISPLAY variable when using xrandr.

How to darken only one screen in a dual screen setup ??

Hi All,
I have a dual screen set-up probably like many of you and sometimes I prefer to use LR only on 1 screen. That allows me to work on Photoshop or read my emails or whatever else I'd prefer to do on the other screen. My dilemma is when in Lightroom & I press the letter L to darken the screen around my image, for better viewing, it also darkens the other screen that I'm working with. Is there a way to prevent both screens from darkening?? Thanks Ron
PS: Apologies if this has been addressed previously as I could not locate it

Thank you digitaldog, I didn't think so either
